This is by far the best Ryzen 7000 optimization guide on YT. Well laid out, explained and informative. Good job!
Thank you for this. Informative without going too far down the rabbit hole and losing the point. I see lots of undervolt videos and nothing about the load line. It helped me get more boost and cooler cooler temps. Can't beat that.
Just an fyi, but before touching load line calibration check for stability of the curve offset first. If you don’t need to touch the load line, don’t. It still increases voltage under load compared to auto which leads to higher temps. This is just to make certain offsets stable when needed.
Amazing, I’ve been obsessed with overclocking lately. I guess I’m a true enthusiast lol 😂 but I’m learning more and more! Thanks to cool guys like you
I was like you back in the mid 20's. I manually enter all my DRAM timings now. Notice how I called it DRAM instead of RAM? I also correct people when they count DRAM speed in Hertz instead of transfers per second. Wanna buy that awesome ROG whatever mobo? Too bad it has throughhole DIMM sockets. Wanna know why that is bad? Trust me you don't. The fact that I can't bring myself to call a DIMM socket a RAM socket like all the normal human beings is reason enough for any of you to steer clear of any overclocking whatsoever. It all started when I first overclocked my Pentium 3 733 50 800 MHz back in the year 2000. The fact that I kind of know physics and material science makes all this unimaginably worse.
There is still hope for you. Cease all overclocking immediately. This includes using the curve optimizer because, well you really don't wanna know why.
@@ahmetrefikeryilmaz4432 plz explain why it's bad i do wanna know
@@-NoodleBoy I am going to save you from yourself and deny you the knowledge you seek so foolishly. LOL I am speaking like a Skyrim NPC
Thank you for this video man!
No nonsense talk. No bullsh**t, Simply good and nice explanation. Through this I finally found the LLC on my Aorus X670. I put my 7800X3D with -45 and Extreme LLC up to 4900Mhz. Lets see how far I can go. Thank you buddy.
nah!! we won't see!
Thx bro, this bios setting solved my idle temperature rising up from 40 to 60 for a few seconds(crazy fans lol)
Came from Intel 6700k. I got that to 5ghz with 1.45 volts. Amd 7900x3d now and it’s so different. Helpful guide! I’m close to world record on 3d mark for a 3080 and 7900x3d set up (says “record for this exact combo of 3080 and 7900x3d” so I’m chasing that haha.
Which mobo do you have ?
@@bomboclutch asrock x670e
5ghz on a 6700k vs a modern cpu isn’t even comparable lol. Also the 7900x3d is a weird cpu where you have the voltage limitations of the 3d cpus and reduced benefit of 3d vcache since it’s only on half the cpu
@@josephbargo5024 obviously not comparable, but considered that majority of people could not hit 5ghz was pretty crazy. The boost stuff with amd is weird but I found not worth it really to mess with. I didn’t get much gains from anything or any guide I’ve tried, and I’ve tried a lot.
Stock I have 33253 With curve -30 and Asus optimized LLC 36580
360 water AIO
Bit of an improvement.
Thanks for the tip!
I get better cinebench scores with undervolt but I get worse wow performance with it so idk
@@bricegardner7815 performance in games, depends on your GPU mostly
maybe the game is not cpu demanding
Thank you for that. Without the extra step that you showed I could only cap out at -33. I could do higher for Cinebench but it failed on stability tests. Once I adjusted the LLC I was able to get it to pass OCCT running for an hour at -40 and capped out at 75C. it should be noted that the LLC does increase temps the higher you go but I was still able to keep everything at a reasonable temp with a 280mm AIO.
Thanks man first video in this topic that really useful. This option really helps 37578 score negative 34.
What wasnt mentioned is that you can also get a mobo that has an external clock generator and overclock the cpu bus. Something to consider additionally is that extreme LLC will put strain on the VRM. Depending on your board and your cooling scenario this can affect the life of your motherboard. Air cooling is actually better for cooling the VRM.
Well done that man! 😄
Thanks man!😀
Amazing explanation!
This was a great great video!!! Now Ryzen directly communicates withe memory controller for the ram; will setting the soc LLC make a difference in the ram or cpu?? Great fookin video mate!!
7900X3D here, stable at 33. Thanks for the tips
Super helpful!
My maaan! I've got the gigabyte Aorus x670 Elite AX REV 1.2 board and the bios is the same as yours. Great explaining what this negative CO does even though I already knew from hours and hours of reddit threads =). I came here to see if I could learn something new that's all! I'm a happy subscriber and hope you can bring more nice content soon for my 7800X3D.
Hi,are you sure bios is exactly same as this? I think your motherboard must be having additional settings like Core clock multiplier and Vcore voltage
@@beardoguyyes of course it got the bclk multipliers and the voltage settings. I haven't made any successful boots with increasing the bclk even to 102.if I had the Asus main board there is modes like eclk 1 and 2 and also asosynchronos mode. My board doesn't have any of those. Those high end Asus board cost like 700 bucks. Mine was around 200, 250 bucks. U get what u pay for. I'm currently happy with the ram tunings I got it to run at CL 26 even though it's cl30 rated. Hynix A die 😅
thanks for replying, by any chance can you send the screenshot/picture of your tweaker(bios) page screen?@@buenosdias8606
Thanks for this video.
What do you recommend having the PBO limit setting on, auto? I see someone recommending "disabled" and "motherboard".
Great content !
My 78003xd runs fine with vcore set to 1.15 volt, curve optimizer -40 all cores, LLC to Level 3 (Asus 650 plus wifi) and PBO thermal limit set to 80 °C. Now the cpu works with max 1.015 volt and 4900 Mhz on all cores. Cinebench 2024 results are 1115 in multi.
LLC is to battle vdroop by giving the cpu more voltage during workloads.
Doubt that the negative value will be stable with prime95 or aida64 SHA3 testing
But nice to know that LLC improves stability
Yes, most CPUs won't be able to do -40 however, LLC prevents the significant vdroop under full load that would be incurred from such as high negative offset. At the same time, the negative CO offset prevents the higher voltage spike that would normally occur after transitioning from full load to low load or idle; due to using LLC.
@@GameTechReviews Asus use pbo scalar 2x and -50 on clock for asus pbo enhancement.
I didn't win the Silicon Lottery and left it on auto and got better performance. So placed my NVME Drive to the middle of the MB and got PCIE4 instead of PCIE3 and got better performance but ran hott. My graphics card slowed down so I placed it back and the NVME is just a little slower but the GPU is at full speed. Cheers!
Damn. I wish I would have seen this video when it dropped. I’ve been researching and tinkering on my 7800X3D and not a single person has mentioned anything about LLC. Here I was, happy with my -15 offset. I’ve just set my SOC to the standard 1.250 which is perfectly reasonable for my cpu.
But now I’m gonna have to go and tinker a little more. Thanks for the awesome tips man! Never seen anything else from your channel, but I’ll sub!
It's likely its a core or two holding you back from going lower. My 7800X3D only does -10 all core, but I just put some time into doing a per core CO and I can do like -40 on 6/8 cores.
@@billedwardz Whelp, I upgraded my cooler to a new 280mm AIO. Currently running -30 all core. Passed every stress test and stability test I've thrown at it over the last 2 days. No crashes yet haha. It's just odd, because I literally haven't changed any other settings. No clue why, but I'll take it!
@@ChrisLaneification Very nice. What'd you end up using to stress it?
@@billedwardz R23 and the entire OCCT suite. Threw in a few games and of course some light load with chrome browsing etc.
But! After a few days of running great, the Small/Extreme CPU test in OCCT caused a crash haha so I’m gonna sit at -25 offset for a bit. Tested everything there and it was fine.
I’ll run more tests as the days go by. But all in all, I’m really happy with the Chip.
@@ChrisLaneification Yeah I have a similar story which is why I asked, I initially was using y-cruncher, which apparently is a more moderate AVX2 or AVX512 load, which got me to -40 on most cores. a few days afterwards I loaded up OCCT and used Small/Extreme/AVX2 and had to lower everything to -30. Honestly we both could probably stay with our initial COs and be fine because IMO OCCTs stress test is probably harder on this chip than anything it would encounter during regular use.
Could you link the discord?
I just got my 7800x3d I've never over or undervolted before. What happens if the system is unstable and shuts down, how do you get back to the bios to fix the number?
Right now my cpu averages 4.4ghz with PBO turned on and no curve optimizer.
Your temps are over TJMax or i am missing something?
i found that changing some values in curve optimizer influences how other cores react,so i can go -33 on some cores and max -11 on others and if i set the -33 to something like -15 than the ones that couldn't run lower than -11 now can run -15...
is this a llc problem? it's on auto for me.
Mine can only do -20 negative offset. Your one must be a super golden sample. But, I made sure mine is stable on every stress test and game test possible
Try only offsetting your gaming cores, 1-8.
@@AverageAsianJoe Those are the weakest cores, so offsetting those isn't going to reduce temps all that much. In fact, the gaming cores have less room for offset than the other cores. The main reason why the 7950X3D is lower power than a 7950X is because of those gaming cores being lower clocked and temperature limited by the 3DVCACHE, which heats things up. So the main problem is the weaker cores run hot, and can't be undervolted as much, while the stronger cores run cooler at the same clocks but also reach higher clocks.
The problem with LLC though is while it stops Vdroop, the opposite side of that coin is you get voltage spikes when load drops, which is actually worse for your CPU in the long run, because you're getting a lot of voltage pumped through a core that is essentially idle, which is far worse, because you're not doing anything with that energy, it's just scouring through the circuits with nowhere to go but to dissipate into heat, which means you might not get higher overall temps, but you will get very high temps over a smaller area of the chip that the sensors won't pick up.
So it's like if a small part of your cores suddenly went up to 100c, but in such a small area that as it dissipates through the chip, by the time it reaches the sensor it's only reading at 70c or less. This means very sharp spikes in voltage/energy, which is worse for electronics than a gradual shift. Temps aren't what kills hardware, it's voltage over time, and voltage spikes. The sudden shifts in voltage results in more dramatic energetic activities in the materials of the chip.
This is one reason why the IHS is soo thick in the first place, it's to keep different areas of the chip from becoming too different in temperature, otherwise those temperature differences at such small scales results in more stress on the materials, including physical cracking and delamination from each other. That's the main reason why the VCACHE is limited in temp. Not because it can't run at those temps, but because it would crack/delaminate from the CPU, because it's not so much built into the CPU, but rather, pasted on top of it and connected by thin circuits. If it was actually manufactured with the chip itself, rather than manufactured separately, the temp limits wouldn't even exist.
Mine only is stable with -12
Mine is stable with Vcore 1,15v and -40 offset.
@@timos.9409 are you using all 16 cores or 1-8 only
This makes sense, but then Bullzoid suggests that LLC is generally a bad thing, because of the spikes it causes. Confusing...
Couldn't you just reduce the CO offset and get the same VCORE result as raising the LLC, but with less transient spikes?
CO is undervolting for the old frequency but actually the voltage stays the same and now you get a higher Frequency at same voltage, as measured with a voltmeter...
Not sure what I’m doing wrong. Using a 7800 x3d and a rog strix b650a.
Set the negative on minus 35 on all cores. And the LLC on level 3 of possible 4. My voltage goes up a little from 0.993V to 1.065V during cinebench. Tried some other LLC levels but only the cpu temperature decreases a little bit. Voltage goes up. Did I miss something?
Wouldn't using a less steep LLC curve, make it produce more heat hence invalidating the Curve Optimizer stuff?
tomorow ill have my new 7900x3d and i will def. check this out : ) im so excited !!!! saved *
Did you try this out? Just picked up a 7900x3d myself.
@@Trampus10-4 make a video how to make our 7950x3d perform the same as 7800x3d for gaming

just for information. running llc on extreme will generate extreme voltage spikes for a short time when the load drops off. this can lead to huge voltage numbers for a short period of time. i dont recommend running llc on extreme!
This is not the same as applying a max llc to a non-x3d which you normally wouldn't do.
I used 35 for the undervolt and scored 37103 on cinebench R23, however i hit a high temp of 85.9 degrees. I see you hit over 90 degrees. No thermal throttling for me, i changed my thermal throttle to 90 degrees anyway, but im just ssying. I could probably go negative 40 but its gonna put my temps over 90 degrees. Im using a 360mm nzxt kraken AIO cooler which is really good, 85.9 is the hottest ive ever seen it get
You probably don't have to worry about it because you're undervolting, but the issue with setting a stiffer LLC is it can cause voltage spikes on transient loads.
Youre fully loaded, the LLC is compensating, there's a cache or memory stall which unloads your CPU but because you're running extra vdroop compensation your voltage spikes until the power stages catch up or the CPU loads again.
Finding the stiffest value that doesn't cause this requires hooking up an oscilloscope to the voltage probe points on your motherboard, as it varies by model/manufacturer/bios revision.
This is my concern (and what has prevented me from messing with the LLC); potential for damaging the CPU with overshoot.
Llc doesn’t raise or have higher spikes. It just helps hold continuous. Cheers.
I've been building pcs for fun for over 20 years. I retired early ,age39 (hey Fu I'm still young at heart) lol but 1) I always buy nvidia gpus
And 2) up until last year always purchased Intel cpus.
Last year I built 3 pcs for myself. Total overkill, one was for my virtualpinball build I built,the other was for my 32inch rec room masters arcade cabinet build.
Both pcs are identical, msi mpg x570 gaming edge wifi motherboards, Ryzen9 5900x cpus, Nzxt 360mm aio coolers , both in corsair 5000D airflow cases. The only difference was (remember this was during the gpu drought) my virtual pinball machine has a rtx3090 founders edition, and my arcade has a rtx3080ti. I fell in love with amd cpus specifically that ryzen 9 5900x 24threads @4.7ghz was no problem.
Ok sorry for the backstop but if everyone here is into pcs and tuning them etc, I love seeing peoples builds and hearing them talk about their systems just as car enthusiasts have car shows.
Anyway, I went with the gigabyte Aorus X670E Master motherboard (thank God so nothing exploded) ryzen 9 7950X3D, grabbed the only pcie5 m.2 drive I could find (microcenter Inland 2tb pcie5 m.2 drive for only $179!!, and yes it gets read and write speeds over 10,000gb/s)
It took lots of updating drivers and bios's but finally the cpu is running as intended. I think I just set my negative to -20 and left it.
Right now I'm using the motherboard above, so hoping some of you are familiar with the layout.
1) I'm unsure but are you saying the graph you show , if its still on a negative curve , even on extreme, it's safe to leave it like that?
2) under where we turn pbo on to advanced, then motherboard, there's a scalar option that's on auto but goes 1-10. Should we just leave that alone?
Lastly,
I want to apologize for all the questions, if you got to know me you would know I try and help every person I can for arcade builds, pcs etc.
But I'm a grown man and can admit, all my years of experience isn't really helping with this ryzen9 7950x3d.
It idles around 40°C and usually games or benchmarks around 60-65°c. Does that seem like normal temperatures? My cpu cooler is once again the NZXT 360MM kraken.
I appreciate anyone whose read this, I have a disability after almost being killed at work so I'm still trying to fight my way back mentally.
As I always do, I like and subscribe to any fellow tech youtuber, even though I'm new at it and onky have 1500members lol 😅
Thank you guys for taking the time to read my long ramblings lol I've loved building pcs since my first 386sx 25mhz pc build. I think it had windows 3.1? Or windows for workgroups whatever was before windows 95. Lol it basically could only run the paint app. Then I went to a computer show , some of you who are in your 40's like me remember having to go to computer shows to buy our hardware before the internet. Lol scored a intel 486DX 66MHZ CPU, WITH 4MB OF RAM. LOL God anyone remember having to run memmaker? Because of the way we had to run games in DOS? Lol
Coupled with the other replies, you must remember that the x3d is different than the x, which you normally wouldn't set to the highest setting. The x3d voltage won't go above its limit. LLC only helps the vdroop remain more stable.
In what situation would the llc need to be on extreme? It’s not necessary for regular gaming right ?
I just set mine to medium to make a -25 all core more stable. No whea errors. This gave me a 14.5k in timespy
i recommend starting from 20 (15 if you want to extra safe) and go up by 2 till most cores are hitting the mh the cpu is meant to hit
I have the 7800x3d in the dan a4 h2O... would it be better to do settings like this or to just use the ECO mode? Not sure if it's more of a personal preference for tradeoffs in performance and temperature or if one is known to be overall better than the other
You can use ECO mode to lower the overall power consumption but that shouldn't be combined with what is shown here. This video focuses on leveraging Curve Optimizer along with LLC to get better performance than stock, or getting the same performance at lower wattage which results in lower temperatures.
complete beginner here, if i used an air cooler and wanted to lower the average power usage during load and idle while achieveing close to the same performance, what can i do? ,
why you using xmp instead of expo 1 ?
checking this video was nice info due im soon upgradeing to a 7800x3D but i did notice you hit 90c on both the core and die temps more or less noticed any thermal throttleing etc bcs of that since it seems high i also know after checking videos that the 7000 series seems to run abit higher temps then the 5000 series but 90c feels abit hot what cooler are you using?
i use a Be quiet Dark Rock Pro 4. Set your PBO Thernal Limit to 80°C and check your Vcore max in uefi. is it higher than 1.25 set it manualy to 1.2 or - 1.15 volt
So there is genuinely no negative from doing any of this? (assuming everything is stable)
With LLC and CO -40 how is your SHA3 CPU test off Aida64?
Stable or instant crash?
Probably instant crash
yes blue screen
Can I achieve the same modification using amd adrenaline software ?
Running a Negative 50 offset stable with this. Super surprised at these results.
I have 7950x3D and I am with MB X670E-PLUS with the "Negative 20" curve Optimizer my PC restarted 2 times in a matter of 3hrs ish maybe? I also Set the Thermal Throttling to be at 75* Cel. Would that mean that my CPU doesn't tolerate even -20 o the curve settings?
😅 RIP

pbo like lower voltage drop allcore oc like higher voltage drop form llc
After you pass a prime95 run of about 6-8h you can say the settings are good. I can run cinebench with even -45 on my 7800x3d but man...the second I press start in prime...boom, crash. After that I started to test each core in OCCT and found out that, 7 of the 8 cores can run at between -21 and -25 and one core is absolute "garbage" and can only run at -13. Yes, curve optimizer is the way to go to lower the temperatures but the architecture on the am5 platform, especially on the 7800x3d is a bit weird, you cannot boost that high the clocks and needs at least a few days of testing to say that your system is 100% stable. After doing all these tweaks I then tested in prime95 and OCCT for about 12h each (the average time my pc is open) and had 0 errors. I saw someone said that picking individual offsets for each core can lower your performance...that is 100% false. You gain performance by doing so, cause each core can boost higher depending on the offset. If you can make 7 cores to boost at a bit over 5ghz and one stays below 5, will always bee better than having all cores limited to 4.8.
The 7000 series x3D chips are technically locked. The 7800x3D will not boost past its top speed of 5050hz without some infinity fabric or multiplier tweaking as the boost overide settings do nothing. It's online but I'm not sure if it is prime stable.
The guy who said you lose performance by applying per core offsets was Michael, one of the first comments. He is greatly mistaken and is applying trying to set per core FREQUENCY in CCD/CCX (not per core CO), which in that case can't be done as it defaults to the lowest core's speed. However, (as you and others have mentioned) per core CO is completely different as it adjusts the voltage offset (not frequency) and it works great . Just a thought on stability testing: Some of the stability tests you mentioned are unrealistic compared to what most people will actually stress their systems in real-world cases. I tend to stress for my worst-case real usage. You could be losing a lot of performance if you stress test for something way outside of your worst-case real-world usage scenario... just something to consider.
@@jimmyhuang7481 You are correct, some of the higher-end mobos, such as the Asus x670e Hero, have a separate bClK adjustment. You set eCLK to asynchronous mode, bCLK1 stays at 100, and bCLK2 you would adjust for cpu frequency (to like 106 or 108.15, etc). Employing that function/strategy/technique along with others can achieve some great overclocks on a processor that is otherwise "locked". I've had a lot of fun with the 7800x3d :)
@@RKBenchmarker i always stress test for worst case scenario, but as you said that is unrealistic for most cases, as I usually game on my pc, for example forza5 or cod can run with no problems, cyberpunk crashes my system the second I play start. Sometimes even the basic youtube videos crashed my pc. Since then i try to find the perfect balance between 100% stability and usual workload/gaming stability. But you cannot go wrong with 100% stability, even at a loss of 2-3 fps.
@@Focaz With your knowledge, you and others could easily set different bios profiles for a set of different games/scenarios if you wanted to take the time. Just another option in the long line of options :) Game hard my friend!
What happens if my motherboard doesn’t have a graph for the LLC? My Asus board goes up to level 8
Hey man, i stumbled across your video and i have a question. I recently bought and build my new system with a Ryzen 7 7800x3d, now im running into a problem with my idle temps, under full load my Peak core voltage is around 1.08-1.10, and while idling it sits around 1.12-1.1.13. do you have any idea how i can fix this? I've tried nearly everything from updating bios, reseating cpu cooling, re applying thermal paste, power plans, updating bios etc but i can't seem to get my idle voltage down. Right now the cpu idles around 53-55 celcius with a 360mm corsair h150i, in game it won't even go above 65 celcius and under full cinebench load this changes to around 77-80 celcius. which in my eyes, does seem like allright temperatures... I've got no clue why my idle voltage is higher than my full load voltage... if anyone got a clue please let me know
Windows power plan needs to be in Balanced mode.
Is it still work? I do -50 mode1 x10
It still 78-81 when play game. Is it work? Or should i buy aio?
I found the vrm settings for my Asus board but it’s way more options and I don’t know what to do on changing it.
TH-cam has many tutorials how to setup bios for OC.
Just search away and you will land on one that gives you all the details.
Dude, I have a 7900X3D and also a Noctua NH-D15 and my Idle temps are mostly around 55C. I got a curve offset of -15 and a 85C temperature limit set in BIOS, but this only helps with temperatures and clock speeds in full load. What else can I do to improve idle temps? Or should I maybe not even be worried about those temps? Also the highest clock speed I can reach is 5.2GHz, never even close to 5.6GHz. I can not use a curve optimizer of -20, so I think I got bad silicon. What do you suggest? Thx
X3D isn't meant to actually get max clocks in benchmarks, even with good liquid coolers. It can clock that high, but it will always reach temp limits before it will clock that high. Those idle temps seem a bit high though, but maybe not. I'd say 45-50 might be better, but it's probably nothing to worry about. About all you can do is set a more aggressive fan curve for the CPU fan. So instead of 20% fan speed at idle, you'd start with 40% at idle and step up from there. i.e. 50% at 60c, 70% at 70c, 80% at 80c, 90% at 85c. Usually CPU fan curve settings have about 4-5 steps, so you'd just try to evenly distribute the fan curve so it ramps up smoothly. Buying a better fan would also help. Try the Noctua industrial fans. They go to 3000RPM, but they're basically identical to the normal noctua fans at 100%, when used at only 50%, but with twice the static pressure. So you don't have to run them at 3000RPM, but you also can if you don't mind the noise for heavy tasks, and they would definitely make a big difference in the amount of air being pushed through.
@@peoplez129 thanks for your reply. I installed some monitoring and benchmarking software in the meantime and did some testing. In single core benchmarks or benchmarks which only stress a few cores the boost reaches 5.5 or even 5.6 GHz, so I think everything's alright now. The rather high idle temps are probably also because of my case and the whole setup. I got a sound dampened case, so the side walls are closed. I run the front and back fans pretty slow via a fan controller, because I want a silent build. That's the reason why it runs pretty hot. Already got a silent CPU fan curve as well.
@@dominik2631 Since you want a quiet system but are choking your cpu due to lack of air flow, I would suggest upgrading your case to a Fractal Torrent as it is the best ranked air case out there, and can run those large front fans slow making it extremely quiet with great airflow! The other choice is get a good AIO, which will help significantly.
Curious to see if you are stable at Aida64 CPU SHA3 performance test with -40 all cores….
This is the most difficult test to stabilize on high negative CO on 3D chips.
And Cinebench is not for stability.
Use instead Corecycler, y-cruncher and your most CPU demanding games….and…last but not least Aida64 CPU SHA3 performance test.
I have a 7950X with a MSI MPG X670E Carbon Wifi, what performance settings would you recommend to keep the temps below 55C on idle?
HI, extreme LLC on Gigagybte, what does that translate to on asus boards? I have an x670e e gaming wifi?
Asus LLC is opposite of others; Asus, highest number is most voltage applied to vdroop. (On other boards, the lowest number is most voltage applied to vdroop).
I guess I have a bad silicone... My 7800X3D only goes to negative 20 with the curve. If I try to go lower my pc doesn't boot...
I need your advice. Two CPUs (7950x3d and 7800x3d) are available for sale: a new 7800x3d for €359 and a 2-month-old 7950x3d for €445. Which one should I go with? (Money is not an issue, and I have a 360 AIO cooler.) Which one should I choose for performance and future-proofing?
7950x3d is better.
I would also run prime95 for a while, your system may seem stable, with -40 but I found that some cores would run into errors, and you don't want that.
I didn't go into the individual cores because I don't want to invest too much time into marginal gains. Now i'm running -20 and EXPO
Are we talking avx enabled or disabled? Prime95 seems to do absolutely nothing to my 7800x3d vs cinebench
i am on -18 all core with a 7800x3d and be stable. -20 or even -19 would be unstable for specific cores.
@@NightForce would the unstability means restarts? I tried with -20 and it restarted twice in 3hrs?
@@alishfitness no, i experienced core-crashes in Prime95. If there were more then 2 cores crashing i even had bluescreens. If your System restarts out of nowhere i would suggest to monitor your temperatures
@@NightForce I am doing that constantly, nothing crosses 65 degrees C. And that's the hot spot. my CPU goes as high as 49 (AIO cooler), GPU I already undervolted and doesn't cross 62 ish. The only thing that I do not monitor is my ram. I have Kingston Fury 2x32 6000. Could that be?
You actually compensate with Extreme LLC the low value of Curve Optimizer.... which is wrong, but hey, have fun doing it.
What happens to me everytime i try curve optimizer on different CPUs is that my computer is fully stable under load but also unstable while idling
My pc wont even boot with these settings any help?
friend is using an Arctic Liquid Freezer II 120 and I think they messed up installing it a bit because it kinda holds back a 7600 (non X)
How is it installed?
What about RAM and Fabric?
So I have a x670e-a and I’ve set the llc to maximum and I see no difference in performance. If I set it to standard or normal I get the same scores in cinebench. This normal?
It doesn't help performance scores, it helps stability so your computer doesn't crash.
@@Daniel-fy2ob gotcha ! Good to know! Thanks
@@Mexi99 Are you using Curve Optimizer? That's where you will see increases. LLC will help with vdroop so the voltage won't go too low and crash.
It doesn’t allow me to go to 40 it just says invalid, any help?
Please help. Recently i swapped from intel to an 7950x3d cpu with an b560e motherboard, but after swapping my nvidia 4080 started to rise the temps in idle mode up to 60 degrees.. usually used to be around 35 degrees in idle , have any toughs?
Did you also upgrade your monitor?
Yes, the 4080 is 320w normal usage 280-300w thats a lot of heat. Install the exhausting fans. Also dont use negative curve -40 all cores like here. With 6000mhz ram and loose timings like 40 40 40 it might work. But if u will go 6400 cl28 or 7800-8000 cl36 100% wont work. Especially in the games. The programs might work but there will be a micro stuttering. With 6400 -30 with 8000 -25 or -20. If u dont believe try to set default 4800 cl 40,40 40 and -50 negative all cores 100% will work. The high temps are always bcos of heat accumulation. So i would say exhaust fans are the best. 🎉😊

My CPU Vcore Loadline Calibration is shown in Levels 1-8 in my uefi, ASUS B650E-I BIOS 1616
On Asus boards, 8 is the most voltage applied to vdroop. On other boards, 1 is the most.
you think just put -15 on ryzen 7950x3d is safe?
Could you please elaborate on whats considered stable?
Stability is a personal choice. Some people consider a system stable as long as it runs all of their programs and games without crashing - even if it crashes under CPU or GPU or RAM stability tests. Others want extreme stability where it won't crash under CPU or GPU or RAM stability tests. Basically, it's up to you to decide.
Hello guys,
I have a problem with this settings.
I have set a curve optimizer per core between negative 15 to negative 30 and loadline calibration to low, but when i run games, benchmark etc, my VID core have peak to 1.365Volt and when i simply wathc youtube o doing nothing the voltage VID stay from 1.2 to 1.3volt.
Have you any advice?
thanks :)
place the vcore lower to 1.2 volt
Wait..... But if you're reducing the voltage per clock under a specific load..... Then raising the LLC..... That means that the voltage is higher at a specific load so you're undoing the benefits you just got from Curve optimiser.
This does not make sense to me
CO undervolts the old 5Ghz. But now at same voltage you get 5.2Ghz.
This is not stable at the same voltage so you need overvoltage, since the CPU is locked, LLC is overvoltage workaround.
Thanks for the video. I noticed your running your ddr5 6000mhz at 5600mhz. Is running rhe ram slower hurting your performance noticeably?
Im running a Aorus Master X670E am5 motherboard with a 7950x3d and a 360ml kraken nzxt cooler. Im just running the negative 30 undervolt and my ram running we expo at 6000mhz. I feel like im leaving a ton of performance on the table, my temps barely hits 60 degrees with fans cranked up . Any ideas to try?.
Pretty sure at 64g of ram the memory controller on the 7000 can't handle that size and speed together. I can run 32g at 6000 cl30 with tight timings no problem but have stability issues and stuttering at 64
@Dunkdamonk , I Judt changed my settings to basicslly a negative 25 undervolt and my cpu runs at 5325mhz and 5725mhz . I had my ram running at 6120mhz and it was running fine, I didn't stress test it though so I'm just running it back it's stock expo1 speed of 6000mhz. My motherboard BIOS just upgraded to accept ddr5 8000mhz and a guy has a video up running xmp ram at 8000mhz with a 7800x3d. I'm not gonna buy a bunch of xmp 8000mhz ram kits until I get one that works lol just gonna stick with my trident 32gb , just turn on EXPO and it's solid at 6000mhz. AMD said their next big 3d chip will be pcie5 so I'll wait for that to come out to try out a new ram kit. I got lucky with my trident kit I have.
@@JerseyJohnnysElectronicsGaming do you know if u have an A die hynix on ur kit or is it samsung? I've never seen amd get those kinds of speeds on x3d chips.
Nice scored a 37103 using a negative 35 undervolt. We have a newer bios, i also have another setting beyond extreme in the bios. They must have just added it.
I've heard that some motherboards have LLC settings that are just so unstable that it causes degradation of the cpu
Is it something I should be concerned about?
LLC settings that add voltage above the zero line should never be used. Those are the settings that will damage the CPU.

@Pikkoroo yes, on Asus motherboards u can do even a -75mV offset volt mode and the cpu is still stable.
I dont like, that the Temps are going above 90°C. This makes the CPU throttling.

You shouldn't have to use extreme only Level 3 should be enough or any of the levels that still results in a decent amount of vdroop.

what bios settings should we do
I have an ASUS motherboard, and I'm hesitant to try this because the LLC options are just levels numbered 1-8, and I don't know how that compares to your "extreme" setting, and my BIOS doesn't include a graph.
Same issue , can't find any info about Asus LLC , so max probably not a good idea .I'm using LLC 6 , Asus bios manual recommends 5 for overclocking so I bumped up by one
Asus LLC settings are opposite of other mobo as Asus' highest number (8 in some cases) is the max LLC setting; whereas 1 is the max llc setting and a larger number is the lower settings on other mobos. Setting max llc on an x3d chip is not the same as setting max llc on a non-x3d (which you normally wouldn't do). However, if you can set llc at a lower v-droop setting and still get your max performance, all the better.
I tried LLC 8 on my Asus mobo with co -37 , instantly almost hits 89 , artic freezer ii 240 open/bench build , at least with LLC6 hovers around 82 , might dial back more , no crashes with R23 or corecycler but instant crash with OCCT
@@RKBenchmarkerhey man you seem really knowledgeable about this. But I always like doing more research and getting more sources. Trouble is not many people are talking about this other than this video
I'm especially interested in seeing more info/sources about 3d chips capping voltage making messing with LLC safer.
My specific situation: Applying per core co offsets that seem stable with core cycler and all core stability tests and gaming. But are weirdly unstable at lighter loads (usually reopening a browser with existing tabs from idle causes bsod).
I'm thinking LLC can help with this. Thoughts?
I follow all his settings for my 7950x3d and it crashed when running CPU benchmark , BLUE SCREEN so if you don't wanna kill your CPU don't follow this video
or don't do EXTREME profile, don't put -negative 40 try other value -30, -20
My 7800x3d is running stable using negative 25 and also negative 30. However, getting worse results at 30 in cinebench. Negative 25 is getting me ~18600, 30 only about 18100. Is there any reason why this could be?
Possibly not stable at those offsets. DId you follow what was shown in the video regarding LLC?
@@GameTechReviews make a video how to make our 7950x3d perform the same as 7800x3d
I think I lost the silicone lottery with my 7950x3d, (without messing with the LLC, but with decent cooling) won't even post at -30 (had to clear CMOS), BSOD at -20, then after a BSOD at only -10; I gave up angry and defeated. Bizarrely, the BSODs (even at -20) would only occur during light desktop activity, never during stress testing, not even after hours and hours of P95. On the upside, the SoC only needs 1.05v for 6000MHz memory clock. My cooler is a Corsair H170i with a 420mm radiator. Motherboard is an MSI MEG X670E ACE. Performance is about 36k in Cinebench R23 without undervolting, so seems hardly worth it to be honest.
Try doing Per Core instead of All Core. There might be a bad core that drags down your entire setup.
@@lpaaaaaaaaaa yeah, I have since found this out. someone else with the same processor could get most of their cores to around -25, but one could only do -8. Thing is, I really don't want to do it per core.
