I did it with the OC Strategy #3. I tested everything with Prime95 and FurMark after the settings and then went into my main game Escape from Tarkov for the final test. I didn't get any errors, crashes or blue screens and my Ryzen 7 7800X3D simply doesn't get warmer than 70° - thank you for the video! Greetings from Germany
You are a monster! Amazing OC video. So much quality info condensed in less than 40m. Many thanks for your the effort you put into making this available.
You are the best overclocker I've seen, and I've seen a lot of them...every one of yours oc's is thoroughly explained to the smallest detail...with you it's easy to understand how silicon valley works...thank you for that...!!!!👍✌️
Wow, @13:20 the correlation with X3D profile plus PBO with stock or PBO (only) is amazing. Seems like easy performance gain with more to come. That chip wants to fly. No wonder you had a great time with this chip.
@@CarnivoryHODL My Crosshair board has 3 X3D profiles that were added to the BIOS after the launch of the AM5 X3D chips. Be sure to check for recent new BIOS
@@ryanodneal7001 Where do you think I’d find it in the bios? I’m on gigabyte, not asus, so what were the x3d profile names and what menu were they on? Thanks so much!
I really like your way of explaining things and amazing that you share your OC:s with the world! The only thing i would personally prefer is that you made the OC on a non closed loop liquid. The majority of ppl doesnt have that good cooling so doing what you recommend with for example an AIO could destory the system.
Sensacional, objetivo e direto... À simplicidade nas explicações atigiu o apce da magnitude. Irei fazer no meu sistema, pois imaginei que não seria possível em tal processador. Fico super grato pelo ensinamenteo.
since the x3D architecture is aimed at being a 'gaming' chip, would it not be best to have a config that allows 1 or 2 cores to boost high rather than an across-the-board medium uplift?
Maybe you've covered this in another video, but can you explain your method for determining your per core curve optimizer offsets? (Or direct me to it) or is it exactly as it seems and is just a time consuming and tedious process if you truly want to have every core at the edge? I'm curious to know your process either way.
It very much is a tedious and time-consumption process. The specific tuning process depends a lot of the specific CPU, because I find that some CPUs are more sensitive to different types of workloads (SSE, AVX, etc). But my general process is pretty simple: Set negative all core curve optimizer, then check stability with Prime95 small ffts no avx for each core separately (affinity). I just check for 20sec because I'm only interested in whether it crashes immediately or not. Then, as long as all cores pass, further increase the negative curve optimizer in steps of 5. Then, when 1 core fails switch to per-core curve optimizer and back down on the one core that failed and keep going with the others. When you have a configuration that works for all cores, it's time to double check stability in various scenarios. I usually do: 1) Per-core SuperPI 32M, to check high-boost stability in light workloads 2) Prime95 small ffts all core non-avx, to check boost in non-avx heavy workload 3) Prime95 small ffts all core avx2, to check boost in avx heavy workload 4) Run all my benchmarks to ensure stability For 1, 2, and 3, you can easily spot which core is unstable and then just back down with Curve Optimizer for that core. For 4, it's more difficult, so I just back down 5 steps for all cores to build in margin.
@@SkatterBencher Thank you so much for taking the time to detail this out. I guess I need to reinstall prime95. It's been years since I used it last and I wasn't aware you could do per core testing. SuperPI will be a huge help too because my biggest issue always seems to be high boost light workload instability with my last few builds. Thanks again. You should consider making this into a video, I can almost guarantee there are a lot of people out there that would love to have this in your usual format as a visual walkthrough for getting the most out of their CO.
@@SkatterBencher Just started my 7800x3D build and I would like to say thanks for this. Got a question regarding 1/2/3 though, how exactly do we spot the failing cores? All cores pass with -30 for 5 mins each for non avx but when I start with avx2 with the same settings it crashes(bsod) immediately and I can't tell which core was doing it heh.
Thank you for this incredibly useful information. Although I cannot find eCLK configurations on my MSI b650-P WIFI, this video inspired me to increase my base clock via the FCH option available to me. I performed a moderate increase of 102, which sped up the entire system just a touch. I used Ryzen Master to understand my best cores, and used HWINFO during gaming to infer the remaining cores capability. My CPUS cores in ordered of best to worst are 2,4,1,3,5,6,8,7 so I simply set a moderate curve optimizer of -5 and -0 for top 2 cores and +5 for the remaining cores. Very stable, no WHEAs, and increased boost clock to a bit over 5200. Thank you again!
Such a in depth video.....I am getting a 7800x3d with a msi x67e carbon wifi in the next week or so....hope I can get as close as possible to your results
I noticed your cpu soc voltage is 1.35v, with the recent news of the burning chips and expo problems, the manufacturers are hard locking the new bios versions to 1.30v max, was wondering your thoughts on this. Many users are manually setting the soc to 1.25v to be on the safe side at least until more info is known. Thanks for the video.
I've been trying to follow the news about the burning up a little bit (including some of the in-depth pieces). Generally, I'm a bit annoyed with the coverage because there's still lots of speculation and jumping to conclusions. Also, I'm not a fan of calling people "lazy" without evidence. It implies intentional malfeasance. My opinion is that 100mV difference will never be the difference between "guaranteed burnout" and "absolute safety", unless there is a specific hardware design flaw causing that. Going by the physical damage, it's clear some thermal protection is failing. That could related to a dysfunctional physical sensor in the CPU or some edge-case SMU firmware bug, or something different. But what's it's not is +100mV :). I look at the BIOS voltage limitations as a way to show customers something's actively being done about it and to shift the conversation to "it's those darned overclockers again". You know ... it's not "in spec" but "out of spec" behavior. I'm not confident we'll ever know the true root cause of this issue. And, honestly, I don't really care that much about the root cause being known by the public. I'm just a bit worried that this will further detract AMD from actively investing resources to enable great overclocking experiences.
Great video, with tons of information. Recently built my first PC in over 20 years and my specific 7800X3D CPU can take a max negative curve optimization of -25 all core when running EXPO tweaked profile. -30 and greater seems to cause stability issues when benchmarking in AIDA64 Extreme.
Hi ScatterBencher! Loved the info you have on the subject. I see in other TH-camrs that they utilize VCore Load Line Calibration, example here th-cam.com/video/4JXvewurhks/w-d-xo.htmlsi=42P_zU-bgKR8f0Wy To my understanding. You’re essentially accomplishing the same end result by adding a positive offset to PBO curve optimizer correct? I just wanted to know if you’d recommend using the VCore Load Line Calibration or just use the curve optimizer by itself?
I suggestion only use loadline calibration if you're doing a manual overclock ("OC Mode") with AMD Ryzen CPUs. If you're sticking with Precision Boost, then Curve Optimizer is the right tool. I experimented with loadline calibration for Ryzen CPUs a while ago and found that adjusting the loadline calibration would make the CPU SMU automatically adjust the requested voltage to offset the loadline. So it cancels each other out.
So the real question. Does it has FPS improvements or just 1% 0.1% lows on games ? thanks for the video, I just build my rig yesterday. 7800x 3d , 64gb 6400 CL32 on a x670e RS Asrock mainboard.
Great video. Helped me to understand what all the acronyms meant. My old 2600k was the last OC I have done. But it has been purring at 4.4ghz under an AIO for 10 years. It idles at lower temp than the 7800x3d which is also under an AIO. But seeing boost to 5150mhz using PBO2 curve at -30 and a 102mhz base clock. Ran p95 at up to 70c for 5 minutes. I am curious what I can undervolt to now to drop a few more degrees. I would like to know if I could OC just the boost. So it has a 5500mhz ceiling but idle and surfing the web only uses stock speeds for the most part.
Newbie here, so from what I can take in, this is a rather hit and miss proceedure with the only monitoring feedback that its working is temperatures, but it could still render your system unstable or even damage your sockets because you are driving them beyond their specified power/current limits? So ultimately, you could be reducing the lifetime of your CPU and motherboard?
I wish eclk was still effective on this cpu for multi core workloads, sadly not the case. Even if i copy your exact settings (theyre not fully stable for me) i dont get anywhere close your frequency, im getting 4620 effective in p95 avx disabled, whereas you were getting 4850. Would you know why exactly? Eclk is still good for single core tho Same motherboard A follow up video on this with a recent bios would be so cool, but it might be a lot of work, i understand
Let's assume there are two V/F points: 5000 MHz at 1.25V and 4500 MHz at 1.15V. Now we use Curve Optimizer to undervolt the processor by 100mV. Then these two V/F Points will become: 5000 MHz at 1.15V and 4500 MHz at 1.05V. We get a lower voltage at a given frequency: 5000 MHz = 1.25V -> 1.15V We get a higher frequency at a given voltage: 1.15V = 4500 -> 5000 MHz

Hello, what was your bios version ? 1101 is instable and does not allow me enable EXPO. When I do it it does not reboot stucks at black screen and if I load overclock preset it gives BSOD.
Have you thought about delidding the CPU?? From other videos I've seen, at least for the non 3d variants, it seems to be more or less free performance, or free power/heat savings. Would be fun to see you maybe push this processor even more, or see how much lower temps/power draw you can get which is quite important for sff builds.
I'm very interested in doing this since mine runs on a fractal ridge case. The ihs seems to be too thick to allow height compatibility with coolers, so removing it already benefits heat transfer
Not in combination with Precision Boost, because the PB algorithm relies on the voltage to estimate the appropriate frequency. With positive curve optimizer, you set the voltage for a given frequency higher. So if the algorithm determines a maximum allowed voltage, the actual maximum allowed frequency will become lower.
great video, many thanks! But "asus x3d oc profile" can be enabled independently from PBO2. So what happens if for example both "PBO CO" and "asus x3d oc profile" are enabled? which one is used?
@@Dodgerca With zen 4, even if you add + voltage to curve optimizer it will not go past the hard cutoff. Temps also will hard stop at the maximum temp. Unless you really go out of your way to disable default protections, it's going to be rather difficult to kill one. The thing that works best for zen 4 is PBO + curve optimizing, maybe eclock if you have it on your board as well, and with these it's very safe.
I've found that the tweaked expo profile from asus bios does actually provide substantially better memory performance at least in memory benchmarking, have you tried it and found any impact on cpu performance?
I've tried EXPO Tweaked (or XMP Tweaked) in one previous OC guide but can't remember which. I didn't see it have impact on CPU overclocking. But then again, I did not test very thoroughly.
I'm using the latest bios 1516, and it doesn't have the "core voltage" option for 7800x3d on the GENE board. I noticed that in the video you are using bios 1002. I'm afraid to go back to this old bios because of the melted cpu problems. Is there any hidden option to release the core voltage, or is it blocked in this bios? Is there any trick to release it?
I have my eclk set to 105 -10 on all cores apart from core 4 wich is set to 0. Temp limit does not go above 83c in cinebench. Is this okay to use daily? I only use for gaming. Thankyou
Ryzen Master has a Curve Optimizing feature that will give the most performant voltage curve per core. I recommend using it because it was very accurate versus my manual tuning would have saved a lot of hours of testing.
Ryzen Master on 7000 should only be used for viewing, pressing "Apply" garbles the BIOS nvram on some AM5 boards (all ASUS in my experience), and you wouldn't be able to boot until you clear CMOS.
EXPO I loads EXPO primary timings, frequency, and voltage but lets the motherboard optimize the rest of the EXPO timings EXPO II loads the full EXPO profile, including the primary and secondary timings, frequency, and voltage. EXPO Tweaked is EXPO I, but also adjusts some non-EXPO profile timings according to the motherboard auto-rules.
Hi and thanks for your work ! Could you please tell us more about Shamino’s Boost Curve tool, where to get it and how to use it, I can't find anything about it on the web. Thank you and best regards.

I have a HUGE question: In my Asus bios for the X570 motherboard, I have TWO sections for AMD overclocking, where both have a PBO submenu. This confuses me, as I do not know what the two separate PBO settings are for. IF you could explain this to me, I would be very grateful.
No catch, Tombexhill is correct. The PBO settings in the AMD Overclocking menu are AMD's "official" BIOS tools whereas the ones in Extreme Tweaker or Ai Tweaker are copies by ASUS to make access easier.
@@SkatterBencher @tombexhill Thank you for the clarification. To better understand: If I change values in both sections, but with different values, how does the bios decide which ones to use? Shall I leave the second on default and work just with the one by AMD? The duality is what confused me. What is the best cause of action? Thank you all for helping out here.
@@towercgaming7891 I've used both and they apply equally I have always left one on default though as I don't know what one it would go to preferentially. I normally use the ones in AI tweaker now as they are easier to get to
I have a ASUS ROG STRIX X670E-E GAMING WIFI but doesn't own a cpu for it yet. I wonder if this motherboard will have similar overclocking potential? Would a AIO 280mm be good enough for max overclocking this cpu? I don't think I can fit a bigger AIO in the case.
@@SkatterBencher Hum okey nice! I didn't have the time to watch the whole video in detail. I will do that now. But here in Sweden it became a paper launch and no accurate info on when they're suppose to arrive either sadly.
I have a tuf b650-e wifi and I noticed your motherboard has a higher power potention for overclocking I have a 7900xt is the difference between the boards worth the money or can you overclock it enough on this board that it will not hold up the gpu
So for any of us on a b650 without ECLK, we're stuck with pbo 2 curve optimizer basically, right? I'm running mine all cores -35 with RAM at 6000 IF 2033 (as per buildzoid hynix timings) and seems stable, but doesn't boost past 5050 mhz, around 82° celsius cinebench r23.
Is it correct to affirm that the strategy 3 is the optimal strategy for anyone who does not want to consume time on fine tuning? Also, I heard that CO ranges from +30 to -30, yet you can still set higher numbers like in your case -35 but in this situation the actual applied value would be -30. could you please verify this piece of information and confirm to me if that's true or false?
OC Strategy #3 is the most balanced in terms of extra frequency and effort required. Correct! +30/-30 used to be the range, but on Raphael it's a bit different. In my Ryzen 7000 launch video I showed up to -300 (three hundred) worked. However, this can change with different AGESA code and I think now the range is more like +30/-60. skatterbencher.com/2022/09/26/raphael-overclocking-whats-new/#AMD_Precision_Boost_Overdrive_2
there is a smidgen of extra performance in manually tuning memory, because EXPO profiles are not good enough. Although the effect of memory tuning is greatly reduced on x3d chips, its still greater than 0.
Good guide although a little confusing. Right now ive set the bios overclock profile and also the curve optimizer but my chip will only do -20. stock max i can get is 17500 in cinebench r23. Think i lost the silicon lottery this time😢 but with these tweeks im at 5ghz all core new score 18766 sad the reviews basic scores was 18k oh well.
- My stock 7800x3d is getting 18466 in in cinebench r23, all cores boost to 4825 Mhz in multi cores, ....and any single core hit 5050 Mhz in hwinfo while browse net or youtube. - Mabe some samples are allready tunned by amd from default with best volttage;) !! - And with -30 on all cores i can hit 18836 points...so 18466 vs 18836..... no such such a big deal ...just a little few points and the speed of single cores still do not surpass 5050Mhz in game , so don't be sad about silicon lottery because is doesn't metter a lot in the case of 7800X3D!!! like in the cases of non x3d who can boost higher the single clock frequency. - Also here in this video i see he get only +200 points in cinebench r23 with -30 on all cores, cause i believe this chip being mostly for gaming do not benefit for increase of more higher single clock while using curve -30, like in cases of others ryzen 7000 non X3D, - Also most people put -30 and forget it and come and report it on forums, and call it stable while is not in most of the cases, - I just see on reddit 4 posts about those cases i'm talking about, a lot of peoples saying put -30 and call it stable but after other users ask them if they test them for 24 hours of prime64 or aida64 sha3 they come back and report they are getting error or crashes. - Also i see other 2 peoples saying them best core support only -5 to -10. - Is the same with my 7800X3D to ! with -30 on all cores i get stable cinebench r23 result, i get all core boost to 5050 Mhz in multi, but single core it's still the same 5050Mhz(the same single 5050Mhz that i was hitting with stock settings to!), also i get stable boosting, also i get sable safe browse net and games, but.......... after i read that posts on reedit i start testing and discover that after 1 -2 hours of prime 95 cpu cores start spiting errors on prime 95 and aida sha3 benchmark!!!!!!!!!!!!!!! - So i decide i will do not keep my cpu with errors reported on prime95 and call it stable like others! and so i have to dial back the best core to -7 !, the other 3 cores to -15/-21/-21, and only the 4 worse cores to -30 to -32!! and only after that prime 95 report 0 error after 5 hours!!! The temperature not such a big deal also to....., on stock 76 C on cinebench r23 multi, and with all cores at - 30 it's hit 79- 80 C cause is boost all cores at 5050 Mhz while on stock all cores boosting at 4825 Mhz, and on prime 95 i get same temp 55-62 C with -30 curve or with stock to!( all core boosting to 4675 -4700Mhz) , and at idle is -3 -4 C less , and in game -3-4C less to, still not such a big difference, oh yes and my aio is 360 in push pull configuration.
Where do I even find the PBO options? I've been scouring my ASRock B650M-DVH/M.2 BIOS but there is nothing in here pointing to PBO related stuff. It was super obvious with my old Asus board on my Ryzen 5800X but not so much here....Help?
Bingo! Thing that i was missing in ECLK OC was increasing per-core CO for failing core...Thx!!!!... I assume you can have smaller ECLK increase, and per-core CO might stay into minuses or you can have bigger ECLK and some of the cores have to move into positive CO . How do you determine max ECLK? at what point are you stopping? As CPU is voltage sensitive are you stopping at first sights that CO needs to go into positives?
Great question! And the boring answer is: it all depends on your CPU :) When you're pushing ECLK and you find there's a bunch of cores that are hitting the fmax, then it makes sense to continue pushing up the eclk to get more frequency. Then start giving the worst core a positive CO. However, if there's only one or two cores hitting the fmax, then it makes sense to leave those be and use negative CO to push up the others a bit.
@SkatterBencher If a motherboard has eCLK, does that mean we can force the CPU to a fixed clock speed when gaming or does the voltage need to be fixed to stop the clock speeds from jumping up & down?
Technically 7000X3D does not support manual overclocking ("OC Mode") which provides the pathway to fixed frequency and voltage. However, you can mimic this behavior as I've shown in OC Strategy #5: Manual Overclock. TLDR: you disable Precision Boost to get a fixed CPU ratio instead of constant fluctuation of clocks.
Hey Skatter Bench, I delid my 7800x3d and confirmed it would post! I don’t plan to use Liquid Metal but PTM 7950. Do you think I could go up to the 1.2V limit with a voltage offset? I am hoping to get an all core OC above 5 ghz using pbo2 and bclk like you did here. Thanks for the detailed guide keep the content coming.
Hi all. I have Rog Strix x670e-e gaming wifi mobo, 32 gb ddr5 6400 cl32 G.SKILL ram, ryzen 7 7800x3d. On current bios 1416 I am able to achive roughly 5335 mhz clock per core on my cpu. Using strategy #3 from this video, didn’t want to try manual core by core settings so did all at once. So my setup is also 6200 mhz, since 6400 mhz was not stable in DOCP I profile (mobo does not have EXPO for some reason, but it is esentialy same thing just different name for Asus). Precision boost overdrive - enabled, curve optimizer - all cores, negative, and i did 25 magnitude. Tried 30 did pass cinebench R23 but in idle crash, 35 magnitude crash instantly, and 25 was stable for me. I can probably go higher on some cores, and some not, but as I said, i didn’t want to do manual per core overclock. Managed to get around 3.25% (give or take) boost in performance (not counting gpu overclock) and from around 5000 mhz max core clock speed to 5335 mhz per core. Temps stable, droped i think 2-3 celsius from 88-89 to 86-87 in full load Cinebench 23. Idle startup is around 45-47, normal to heavy workload 65-75 celsius and veryhigh workload 86 celsius. Cinebench R23 score - before cpu overclock somewhere around 17400, after overclock 18051. I do not play highly intensive games, and even without OC i had enough fps in games, but did it anyway just to check the results and pass info here since there is almost none cpu overclock videos of this cpu after this fiasco with Asus and their burned up cpu and mobo. I couldn’t hit chinebench 23 scores he hit in this video, but i think that is due mobo diference (his is higer rank and have 20+2 A teamed power solution rate while mine have 18+2 , maybe clean windows 11 instalation, and some other thing, I don’t know, I am not expert, and don’t even know is that ever relevant for cpu overclock, but I have seen my cpu hit 18200 (give or take) score in Cinebench R23 when we put sistem together and did first few testings. Hope this helps someone.
Great videos man, i really like your methodical presentation you must be a teacher, either way makes it really easy to follow and im learning allot from your SkatterBencher series thanks!
Hi, if i use my 7800x3d with blck 102.93 i get in windows almost 5.2ghz.. should i use pbo with this method or disable? Right now i am using pbo amd eco 170w setting with a curve -10 all cores stable prime95.
SkatterBencher Would you answer one more question for me please. Is there a difference between PBO Enabled and PBO Enhanced (70-80-90c) on an Asus motherboard for the x3d chip or a regular chip.
Any idea why I would be seeing subpar performance compared to a 5800X3D/4090 with my 7800X3D/4090/Hero combo. I am seeing 15% lower performance then my wife's system? I think I have a Mobo issue but no way of verifying.

@@SkatterBencher It’s titled something like “easy 7000 ram timings” by buildzoid, if you haven’t seen yet. Sounds like it’ll work fine w/ the 7800x3d, but wanted your thoughts. Means so much!
I'm running a Gigabyte b650 Pro ax mb with 7800x3d. With pbo enabled and a negative 30 offset on curve optimiser my cinebench score is around 18900 and all cores are boosting to 5ghz. And during gaming some single cores are boosting to 5600 mhz. Seems strange how much its boosting according to hw info. I have no oc in mb enabled. Unless optimised default automatically runs one 🤷♂️ I've just changed a power setting within pbo settings from motherboard to auto so maybe it was charging something which made it boost higher as now its stopping within under 4900

Sensacional, objetivo e direto... À simplicidade nas explicações atigiu o apce da magnitude. Irei fazer no meu sistema, pois imaginei que não seria possível em tal processador. Fico super grato pelo ensinamenteo.
agora me ajuda kkkkkk ensina
since the x3D architecture is aimed at being a 'gaming' chip, would it not be best to have a config that allows 1 or 2 cores to boost high rather than an across-the-board medium uplift?
Id love a 6 core 3dv cpu with 1-2 super-cores,thats the dream cpu :O
Maybe you've covered this in another video, but can you explain your method for determining your per core curve optimizer offsets? (Or direct me to it) or is it exactly as it seems and is just a time consuming and tedious process if you truly want to have every core at the edge? I'm curious to know your process either way.
It very much is a tedious and time-consumption process. The specific tuning process depends a lot of the specific CPU, because I find that some CPUs are more sensitive to different types of workloads (SSE, AVX, etc). But my general process is pretty simple:
Set negative all core curve optimizer, then check stability with Prime95 small ffts no avx for each core separately (affinity). I just check for 20sec because I'm only interested in whether it crashes immediately or not. Then, as long as all cores pass, further increase the negative curve optimizer in steps of 5.
Then, when 1 core fails switch to per-core curve optimizer and back down on the one core that failed and keep going with the others.
When you have a configuration that works for all cores, it's time to double check stability in various scenarios. I usually do:
1) Per-core SuperPI 32M, to check high-boost stability in light workloads
2) Prime95 small ffts all core non-avx, to check boost in non-avx heavy workload
3) Prime95 small ffts all core avx2, to check boost in avx heavy workload
4) Run all my benchmarks to ensure stability
For 1, 2, and 3, you can easily spot which core is unstable and then just back down with Curve Optimizer for that core. For 4, it's more difficult, so I just back down 5 steps for all cores to build in margin.
@@SkatterBencher Thank you so much for taking the time to detail this out. I guess I need to reinstall prime95. It's been years since I used it last and I wasn't aware you could do per core testing. SuperPI will be a huge help too because my biggest issue always seems to be high boost light workload instability with my last few builds.
Thanks again. You should consider making this into a video, I can almost guarantee there are a lot of people out there that would love to have this in your usual format as a visual walkthrough for getting the most out of their CO.
I use OCCT and test 1 core at a time, takes forever but works.
@@SkatterBencher What about using Ryzen Master and running the per core optimizer, and either just using Master or entering the offset in your bios?
@@SkatterBencher Just started my 7800x3D build and I would like to say thanks for this. Got a question regarding 1/2/3 though, how exactly do we spot the failing cores? All cores pass with -30 for 5 mins each for non avx but when I start with avx2 with the same settings it crashes(bsod) immediately and I can't tell which core was doing it heh.
Thank you for this incredibly useful information. Although I cannot find eCLK configurations on my MSI b650-P WIFI, this video inspired me to increase my base clock via the FCH option available to me. I performed a moderate increase of 102, which sped up the entire system just a touch. I used Ryzen Master to understand my best cores, and used HWINFO during gaming to infer the remaining cores capability. My CPUS cores in ordered of best to worst are 2,4,1,3,5,6,8,7 so I simply set a moderate curve optimizer of -5 and -0 for top 2 cores and +5 for the remaining cores. Very stable, no WHEAs, and increased boost clock to a bit over 5200.
Thank you again!
Hello my friend can we contact in discord can you send me your discord please
Such a in depth video.....I am getting a 7800x3d with a msi x67e carbon wifi in the next week or so....hope I can get as close as possible to your results
does this mb has external clock generator? to oc bus to 105-110Mhz?
@@MrGrzegorzD It does not, you need to go up to the $700 x670e boards for that. I'm not sure about options on the lower end chipsets.

I noticed your cpu soc voltage is 1.35v, with the recent news of the burning chips and expo problems, the manufacturers are hard locking the new bios versions to 1.30v max, was wondering your thoughts on this. Many users are manually setting the soc to 1.25v to be on the safe side at least until more info is known. Thanks for the video.
I've been trying to follow the news about the burning up a little bit (including some of the in-depth pieces). Generally, I'm a bit annoyed with the coverage because there's still lots of speculation and jumping to conclusions. Also, I'm not a fan of calling people "lazy" without evidence. It implies intentional malfeasance.
My opinion is that 100mV difference will never be the difference between "guaranteed burnout" and "absolute safety", unless there is a specific hardware design flaw causing that. Going by the physical damage, it's clear some thermal protection is failing. That could related to a dysfunctional physical sensor in the CPU or some edge-case SMU firmware bug, or something different. But what's it's not is +100mV :).
I look at the BIOS voltage limitations as a way to show customers something's actively being done about it and to shift the conversation to "it's those darned overclockers again". You know ... it's not "in spec" but "out of spec" behavior. I'm not confident we'll ever know the true root cause of this issue. And, honestly, I don't really care that much about the root cause being known by the public. I'm just a bit worried that this will further detract AMD from actively investing resources to enable great overclocking experiences.
@@SkatterBencher Thanks man, appreciate you taking the time to answer.😀
amazing video - very insightful!
Great material. Thank you!
Great video, with tons of information. Recently built my first PC in over 20 years and my specific 7800X3D CPU can take a max negative curve optimization of -25 all core when running EXPO tweaked profile. -30 and greater seems to cause stability issues when benchmarking in AIDA64 Extreme.
Thanks for doing this.
The pleasure was all mine this time :)
thanks for the video :D
Hi ScatterBencher! Loved the info you have on the subject. I see in other TH-camrs that they utilize VCore Load Line Calibration, example here th-cam.com/video/4JXvewurhks/w-d-xo.htmlsi=42P_zU-bgKR8f0Wy
To my understanding. You’re essentially accomplishing the same end result by adding a positive offset to PBO curve optimizer correct? I just wanted to know if you’d recommend using the VCore Load Line Calibration or just use the curve optimizer by itself?
I suggestion only use loadline calibration if you're doing a manual overclock ("OC Mode") with AMD Ryzen CPUs. If you're sticking with Precision Boost, then Curve Optimizer is the right tool.
I experimented with loadline calibration for Ryzen CPUs a while ago and found that adjusting the loadline calibration would make the CPU SMU automatically adjust the requested voltage to offset the loadline. So it cancels each other out.
I have a 7800x3D with asus b650e-I and I don’t have the overcooking presets options (I did update my bios to the latest version
so 7800X3D is basically faster then the 7950X3D 3D cache enabled only?
Don't mistake a silicon lottery result for an average.
So the real question. Does it has FPS improvements or just 1% 0.1% lows on games ? thanks for the video, I just build my rig yesterday. 7800x 3d , 64gb 6400 CL32 on a x670e RS Asrock mainboard.
Great video. Helped me to understand what all the acronyms meant. My old 2600k was the last OC I have done. But it has been purring at 4.4ghz under an AIO for 10 years. It idles at lower temp than the 7800x3d which is also under an AIO. But seeing boost to 5150mhz using PBO2 curve at -30 and a 102mhz base clock. Ran p95 at up to 70c for 5 minutes. I am curious what I can undervolt to now to drop a few more degrees.
I would like to know if I could OC just the boost. So it has a 5500mhz ceiling but idle and surfing the web only uses stock speeds for the most part.
So whats the best Setting for Gaming ? 7800X3D asus B650E E Gaming
This video is still understandable at 2x speed. I congratulate You.
educated! your voltage reference and strategy is priceless. I would try tweaking and curving the voltages low enough for an air cooler.
It's very easy to aircool the 7800x3d
@@havz0r what are you talking about?
even a random grandma can aircool any recent gen CPU if vcore voltage set to 1.2V
Correct me if I’m wrong but if you set pbo to enhancement & then set it to your motherboard - the motherboard will limit the CPU’s potential ?
Newbie here, so from what I can take in, this is a rather hit and miss proceedure with the only monitoring feedback that its working is temperatures, but it could still render your system unstable or even damage your sockets because you are driving them beyond their specified power/current limits? So ultimately, you could be reducing the lifetime of your CPU and motherboard?
Thats insane! Thank you
I wish eclk was still effective on this cpu for multi core workloads, sadly not the case. Even if i copy your exact settings (theyre not fully stable for me) i dont get anywhere close your frequency, im getting 4620 effective in p95 avx disabled, whereas you were getting 4850.
Would you know why exactly?
Eclk is still good for single core tho
Same motherboard
A follow up video on this with a recent bios would be so cool, but it might be a lot of work, i understand
I was waiting for it!

Yes 5.6 without a load.
Hi, I don't understand why you state at 16:02
Lower voltage for a given frecuency = Higher frequency at a given voltage.
Let's assume there are two V/F points: 5000 MHz at 1.25V and 4500 MHz at 1.15V.
Now we use Curve Optimizer to undervolt the processor by 100mV. Then these two V/F Points will become: 5000 MHz at 1.15V and 4500 MHz at 1.05V.
We get a lower voltage at a given frequency: 5000 MHz = 1.25V -> 1.15V
We get a higher frequency at a given voltage: 1.15V = 4500 -> 5000 MHz
Great video!
Excellent OC review as always, thank you! Quick question: where can anyone find the "Shamino's Boost Curve" tool for download? Thank you in advance!

Hello, what was your bios version ? 1101 is instable and does not allow me enable EXPO. When I do it it does not reboot stucks at black screen and if I load overclock preset it gives BSOD.
Have you thought about delidding the CPU?? From other videos I've seen, at least for the non 3d variants, it seems to be more or less free performance, or free power/heat savings. Would be fun to see you maybe push this processor even more, or see how much lower temps/power draw you can get which is quite important for sff builds.
I've thought about it, but don't have the time to do it
I'm very interested in doing this since mine runs on a fractal ridge case. The ihs seems to be too thick to allow height compatibility with coolers, so removing it already benefits heat transfer
would doing the curve optimizer in the postive direction yield better results if I dont care about the extra voltage and temps?
Not in combination with Precision Boost, because the PB algorithm relies on the voltage to estimate the appropriate frequency. With positive curve optimizer, you set the voltage for a given frequency higher. So if the algorithm determines a maximum allowed voltage, the actual maximum allowed frequency will become lower.
great video, many thanks!
But "asus x3d oc profile" can be enabled independently from PBO2. So what happens if for example both "PBO CO" and "asus x3d oc profile" are enabled? which one is used?
Almost ready to receive my CPU, I'll be trying all of this strategies for OC. Thanks for the guidance.
Good luck!
How likely are these strategies to brick your cpu? Ranging from ‘pretty darn low you’ll cook your cpu’ through to ‘try at your own extreme risk’?
@@Dodgerca With zen 4, even if you add + voltage to curve optimizer it will not go past the hard cutoff. Temps also will hard stop at the maximum temp. Unless you really go out of your way to disable default protections, it's going to be rather difficult to kill one. The thing that works best for zen 4 is PBO + curve optimizing, maybe eclock if you have it on your board as well, and with these it's very safe.
Do is possible to do strategies #2 and #3 together? ASUS X3D OC Profile + Negative Curve Optimizer?
I've found that the tweaked expo profile from asus bios does actually provide substantially better memory performance at least in memory benchmarking, have you tried it and found any impact on cpu performance?
I've tried EXPO Tweaked (or XMP Tweaked) in one previous OC guide but can't remember which. I didn't see it have impact on CPU overclocking. But then again, I did not test very thoroughly.
I'm using the latest bios 1516, and it doesn't have the "core voltage" option for 7800x3d on the GENE board.
I noticed that in the video you are using bios 1002.
I'm afraid to go back to this old bios because of the melted cpu problems.
Is there any hidden option to release the core voltage, or is it blocked in this bios?
Is there any trick to release it?
Thanks for sharing,awesome
In my bios there is no "eCLK" to set. Is that because my board simply does not have external clock generator?
Yes
this 3dx extreme profile isn't available on my Asus Strix B650E-F :C, my 7800x does not cross 5ghz,
Where to find this external clock in ASRock x670e board? Anyone? I did curve undervolt but can't find eckl anywhere...
I have my eclk set to 105 -10 on all cores apart from core 4 wich is set to 0.
Temp limit does not go above 83c in cinebench.
Is this okay to use daily? I only use for gaming. Thankyou
Ryzen Master has a Curve Optimizing feature that will give the most performant voltage curve per core. I recommend using it because it was very accurate versus my manual tuning would have saved a lot of hours of testing.
For me, Ryzen Master has no option to optimize the curve. I heard that it's disabled for X3D CPUs. Got any ideas?
Looks like it is only for 5000 series
Ryzen Master on 7000 should only be used for viewing, pressing "Apply" garbles the BIOS nvram on some AM5 boards (all ASUS in my experience), and you wouldn't be able to boot until you clear CMOS.
What is the difference between EXPO I vs. II vs. Tweaked?
Can not find any info on the profile differences on ASUS / G.Skills websites.
EXPO I loads EXPO primary timings, frequency, and voltage but lets the motherboard optimize the rest of the EXPO timings
EXPO II loads the full EXPO profile, including the primary and secondary timings, frequency, and voltage.
EXPO Tweaked is EXPO I, but also adjusts some non-EXPO profile timings according to the motherboard auto-rules.

FYI I've grilled my CPU by using the Get VF function of Shamino tools. Be careful.
I have a HUGE question: In my Asus bios for the X570 motherboard, I have TWO sections for AMD overclocking, where both have a PBO submenu. This confuses me, as I do not know what the two separate PBO settings are for. IF you could explain this to me, I would be very grateful.
Either menu applies the PBO settings just choose one and stick to it 😊
@@tombexhill This makes no sense, as you can set either of them with very different settings. There must be a catch.
No catch, Tombexhill is correct.
The PBO settings in the AMD Overclocking menu are AMD's "official" BIOS tools whereas the ones in Extreme Tweaker or Ai Tweaker are copies by ASUS to make access easier.
@@SkatterBencher @tombexhill Thank you for the clarification. To better understand: If I change values in both sections, but with different values, how does the bios decide which ones to use? Shall I leave the second on default and work just with the one by AMD? The duality is what confused me. What is the best cause of action? Thank you all for helping out here.
@@towercgaming7891 I've used both and they apply equally I have always left one on default though as I don't know what one it would go to preferentially. I normally use the ones in AI tweaker now as they are easier to get to
I have a ASUS ROG STRIX X670E-E GAMING WIFI but doesn't own a cpu for it yet. I wonder if this motherboard will have similar overclocking potential? Would a AIO 280mm be good enough for max overclocking this cpu? I don't think I can fit a bigger AIO in the case.
Depends more about silicon and cooling not that much about mobo
At worst, when overclocked this CPU pulls only 100W. Any decent air cooler will handle that.
@@SkatterBencher Hum okey nice! I didn't have the time to watch the whole video in detail. I will do that now. But here in Sweden it became a paper launch and no accurate info on when they're suppose to arrive either sadly.

Which mobo is the most affordible with a ext clock gen?
thanks for your nice video.I wanna know which motherboard could be the cheapest to change the eclk ，could you please provide an answer?
I have a tuf b650-e wifi and I noticed your motherboard has a higher power potention for overclocking I have a 7900xt is the difference between the boards worth the money or can you overclock it enough on this board that it will not hold up the gpu
So for any of us on a b650 without ECLK, we're stuck with pbo 2 curve optimizer basically, right? I'm running mine all cores -35 with RAM at 6000 IF 2033 (as per buildzoid hynix timings) and seems stable, but doesn't boost past 5050 mhz, around 82° celsius cinebench r23.
at the moment it seems like it. Hopefully somebody finds a work around.
Is it correct to affirm that the strategy 3 is the optimal strategy for anyone who does not want to consume time on fine tuning?
Also, I heard that CO ranges from +30 to -30, yet you can still set higher numbers like in your case -35 but in this situation the actual applied value would be -30. could you please verify this piece of information and confirm to me if that's true or false?
OC Strategy #3 is the most balanced in terms of extra frequency and effort required. Correct!
+30/-30 used to be the range, but on Raphael it's a bit different. In my Ryzen 7000 launch video I showed up to -300 (three hundred) worked. However, this can change with different AGESA code and I think now the range is more like +30/-60.

there is a smidgen of extra performance in manually tuning memory, because EXPO profiles are not good enough. Although the effect of memory tuning is greatly reduced on x3d chips, its still greater than 0.

@@SkatterBencher Does it work also with a B650 motherboard?
Good guide although a little confusing. Right now ive set the bios overclock profile and also the curve optimizer but my chip will only do -20.
stock max i can get is 17500 in cinebench r23. Think i lost the silicon lottery this time😢 but with these tweeks im at 5ghz all core new score 18766 sad the reviews basic scores was 18k oh well.
- My stock 7800x3d is getting 18466 in in cinebench r23, all cores boost to 4825 Mhz in multi cores, ....and any single core hit 5050 Mhz in hwinfo while browse net or youtube.
- Mabe some samples are allready tunned by amd from default with best volttage;) !!
- And with -30 on all cores i can hit 18836 points...so 18466 vs 18836..... no such such a big deal ...just a little few points and the speed of single cores still do not surpass 5050Mhz in game , so don't be sad about silicon lottery because is doesn't metter a lot in the case of 7800X3D!!! like in the cases of non x3d who can boost higher the single clock frequency.
- Also here in this video i see he get only +200 points in cinebench r23 with -30 on all cores, cause i believe this chip being mostly for gaming do not benefit for increase of more higher single clock while using curve -30, like in cases of others ryzen 7000 non X3D,
- Also most people put -30 and forget it and come and report it on forums, and call it stable while is not in most of the cases,
- I just see on reddit 4 posts about those cases i'm talking about, a lot of peoples saying put -30 and call it stable but after other users ask them if they test them for 24 hours of prime64 or aida64 sha3 they come back and report they are getting error or crashes.
- Also i see other 2 peoples saying them best core support only -5 to -10.
- Is the same with my 7800X3D to ! with -30 on all cores i get stable cinebench r23 result, i get all core boost to 5050 Mhz in multi, but single core it's still the same 5050Mhz(the same single 5050Mhz that i was hitting with stock settings to!), also i get stable boosting, also i get sable safe browse net and games, but.......... after i read that posts on reedit i start testing and discover that after 1 -2 hours of prime 95 cpu cores start spiting errors on prime 95 and aida sha3 benchmark!!!!!!!!!!!!!!!
- So i decide i will do not keep my cpu with errors reported on prime95 and call it stable like others! and so i have to dial back the best core to -7 !, the other 3 cores to -15/-21/-21, and only the 4 worse cores to -30 to -32!! and only after that prime 95 report 0 error after 5 hours!!!
The temperature not such a big deal also to....., on stock 76 C on cinebench r23 multi, and with all cores at - 30 it's hit 79- 80 C cause is boost all cores at 5050 Mhz while on stock all cores boosting at 4825 Mhz, and on prime 95 i get same temp 55-62 C with -30 curve or with stock to!( all core boosting to 4675 -4700Mhz) , and at idle is -3 -4 C less , and in game -3-4C less to, still not such a big difference, oh yes and my aio is 360 in push pull configuration.
Where do I even find the PBO options? I've been scouring my ASRock B650M-DVH/M.2 BIOS but there is nothing in here pointing to PBO related stuff.
It was super obvious with my old Asus board on my Ryzen 5800X but not so much here....Help?

Bingo! Thing that i was missing in ECLK OC was increasing per-core CO for failing core...Thx!!!!... I assume you can have smaller ECLK increase, and per-core CO might stay into minuses or you can have bigger ECLK and some of the cores have to move into positive CO . How do you determine max ECLK? at what point are you stopping? As CPU is voltage sensitive are you stopping at first sights that CO needs to go into positives?
Great question! And the boring answer is: it all depends on your CPU :)
When you're pushing ECLK and you find there's a bunch of cores that are hitting the fmax, then it makes sense to continue pushing up the eclk to get more frequency. Then start giving the worst core a positive CO. However, if there's only one or two cores hitting the fmax, then it makes sense to leave those be and use negative CO to push up the others a bit.
@@SkatterBencher what are the signs that a particular core is hitting fmax?
Great video.
@SkatterBencher If a motherboard has eCLK, does that mean we can force the CPU to a fixed clock speed when gaming or does the voltage need to be fixed to stop the clock speeds from jumping up & down?
Technically 7000X3D does not support manual overclocking ("OC Mode") which provides the pathway to fixed frequency and voltage. However, you can mimic this behavior as I've shown in OC Strategy #5: Manual Overclock. TLDR: you disable Precision Boost to get a fixed CPU ratio instead of constant fluctuation of clocks.
Hey Skatter Bench,

Hi all.
I have Rog Strix x670e-e gaming wifi mobo, 32 gb ddr5 6400 cl32 G.SKILL ram, ryzen 7 7800x3d.
On current bios 1416 I am able to achive roughly 5335 mhz clock per core on my cpu.
Using strategy #3 from this video, didn’t want to try manual core by core settings so did all at once.
So my setup is also 6200 mhz, since 6400 mhz was not stable in DOCP I profile (mobo does not have EXPO for some reason, but it is esentialy same thing just different name for Asus).
Precision boost overdrive - enabled, curve optimizer - all cores, negative, and i did 25 magnitude. Tried 30 did pass cinebench R23 but in idle crash, 35 magnitude crash instantly, and 25 was stable for me. I can probably go higher on some cores, and some not, but as I said, i didn’t want to do manual per core overclock.
Managed to get around 3.25% (give or take) boost in performance (not counting gpu overclock) and from around 5000 mhz max core clock speed to 5335 mhz per core. Temps stable, droped i think 2-3 celsius from 88-89 to 86-87 in full load Cinebench 23. Idle startup is around 45-47, normal to heavy workload 65-75 celsius and veryhigh workload 86 celsius.
Cinebench R23 score - before cpu overclock somewhere around 17400, after overclock 18051.
I do not play highly intensive games, and even without OC i had enough fps in games, but did it anyway just to check the results and pass info here since there is almost none cpu overclock videos of this cpu after this fiasco with Asus and their burned up cpu and mobo.
I couldn’t hit chinebench 23 scores he hit in this video, but i think that is due mobo diference (his is higer rank and have 20+2 A teamed power solution rate while mine have 18+2 , maybe clean windows 11 instalation, and some other thing, I don’t know, I am
not expert, and don’t even know is that ever relevant for cpu overclock, but I have seen my cpu hit 18200 (give or take) score in Cinebench R23 when we put sistem together and did first few testings.
Hope this helps someone.

I'm wonder about new edition Ryzen 7 9800x3D how fast will You ahve it ? ther will be lower power consumpiont moore room to overclock 🙂
So how do we figure out which values to use for our own cpu?
The fact he uses asus makez me roll my eyes, would be nice if he used boards that werent overpriced in his tutorials, asrock has boards that are just as good for much less
I have a asrock mobo and this was easy to follow, I used strat #3
@@puffyipsi have asrock taichi. Can you share your guide
Did you experiment with the max frequency boost setting on the 7800X3D at all? I was surprised to see it not mentioned in this video, considering how much detail and thought has been put into it.
That setting has for some reason been disabled by AMD on vcache CCD's, even for their flagship.
Fmax Boost Override doesn't work on X3D CCDs, unfortunately.
@@SkatterBencher weird that the menu option was still there then, it disappears with my 5800X3D
When OCing RAM w/ this chip, what should the max VSOC be? 1.15v?
Since the memory controller is integrated in the IO die, not the CPU dies, you can run standard EXPO voltages (1.4V is fine)
@@SkatterBencher huge help for a novice. Thanks!
@@SkatterBencher Have you seen Buildzoid’s easy ram timings video? Would these timings be stable with the 7800x3d OCed vs EXPO?
I may have seen the video. Stability depends heavily on the specific memory and CPU, but in theory it should be possible to make it work
@@SkatterBencher It’s titled something like “easy 7000 ram timings” by buildzoid, if you haven’t seen yet. Sounds like it’ll work fine w/ the 7800x3d, but wanted your thoughts. Means so much!
I'm running a Gigabyte b650 Pro ax mb with 7800x3d. With pbo enabled and a negative 30 offset on curve optimiser my cinebench score is around 18900 and all cores are boosting to 5ghz. And during gaming some single cores are boosting to 5600 mhz. Seems strange how much its boosting according to hw info. I have no oc in mb enabled. Unless optimised default automatically runs one 🤷♂️ I've just changed a power setting within pbo settings from motherboard to auto so maybe it was charging something which made it boost higher as now its stopping within under 4900
You're gonna blow up your CPU and MB.
you must be new here
Do i risk messing up my NVME drives if i run higher bus speed than the default 100MHz? tnx
On Ryzen 5000, yes.
On Ryzen 7000 in Sync mode, yes.
On Ryzen 7000 in Async mode, no.
@@SkatterBencher Thank you. Unfortunately my Gigabyte b650e board doesnt specify if it is in sync or async mode. Only has "CPU clock control" so i think its best i play it safe and dont touch it. Thank you!
@@bismuth7730it's sync, because your Mobo doesn't have an eclk generator
