lofi OC Buildzoid ramblings to relax/study to
Legit I fall asleep to his streams, they're weirdly relaxing. There's something about being vaguely interested in the topic and a tired brain that basically shuts it off
I WAS GONNA DO IT TO JAJAJ
Very informative and friendly to new Ryzen users / overclockers. Thank you!
i thank you, im too poor for more then premium and this guy deserves it.
Despite the channel being called Actually Hardcore Overclocking, I love all the real world advice for normal people who just want to OC with an AiO or an aircooler and run their systems stable 24/7. Very useful. I will come back to this when I get my 9950X3D.
Best oc video I've seen in a long time. Big thanks!
it is so valuable to have an accessible resource explaining how and why things work, not just skipping it to the results.
Probably worth mentioning that the minimum Vsoc requirement is also dependent on the number of PCIe lanes in use.
For example, I got a 7950X that can do DDR5-6400 at 1.21V as long as you don't connect PCIe devices, once you connect a GPU and/or M.2(s), and use either, it requires 1.24V Vsoc to keep running stable with the same timings. Therefore, I always run FurMark in parallel to y-cruncher, etc. when tuning timings that feel on the edge.
Too low Vsoc seems also the reason if you see flickering graphics when using the iGPU while testing. I had that on a different CPU, and raising the Vsoc by 20mV got rid of the flicker.
Also, always check your BIOS if you are in 1:1 !!!
My B650 LiveMixer (3.08 BIOS) switches to 2:1 when setting the XMP to 6000;
My B650E Aorus Master happily boots 6600 in 1:1 with any F31 and later BIOS I tested so far;
If you want easy 2:1 8000, try to get an X670E Crosshair Gene, took me 5 minutes to OC an Epyc 4124P to DDR5-8000 with 2200 FCLK 🤣
I've not run into the PCI-e thing but I'll look into.
Is that same cpu on all these mobos ?
@@ActuallyHardcoreOverclockingso running iGPU should lower Vsoc requirements for 6400 in 1:1 mode compared to running actual PCI-e GPU?
Could you test this?
does iGPU on/off influence vSoC or other requirements for stability?
@@Flank.Sinatra. and more than that, iGPU idle vs iGPU running Furmark could also skew Vsoc requirements at the same 1:1 memory ratio.
We enjoy your videos . Please never give up .
This is FCLK-ing awesome
YES IT IS!!!
What a wholesome video. Listened to this while driving (AirPods) and will revisit it later tonight when the wife and kid is asleep to really understand how to maximize my AM5 systems. Never stop doing these videos Build-Chad-Zoid!
Finally a TH-camr that actually knows how ram works. Just about everyone else is clown level
Word! Only listen to this guy when it comes to RAM.
Lol. Sad state of affairs if this guy is considered anywhere near the top.
I know more than he does by a ridiculous amount. Proven by my OC's in the past that he couldn't even come close to achieving.
Talk to me when he's achieved anywhere near 6600mhz CL28 with a 2200mhz FCLK. Actually stable. Something this man has a huge problem doing.
@@nexxusty I mean you need a gold sample CPU to do 2200 and 6600. Have you considered that not everyone has a gold sample CPU?
@@nexxustyyou sound like a clown who doesn’t actually know anything about
@@nexxusty if 6600 CL28 1:1 is so easy where's your How To Guide that makes it work on every CPU?
Boys play with toys, men play with ram timings on their motherboard to get artifical syncretic benchmark results that hardly translate to actual preformance B)
No but seriously this is an good and easily understandable guide thanks for making this.
Amazing content. A lot of suggestions out there on AM5 memory ratios just seem to handwave away talking about the memory controller and the fabric not being syncronised.
It certainly sounds like DDR5-8000 in 4000:2000:2000 is the superior option if you can get it to work, and it has the advantage of not needing to win the silicon lottery on the CPU side as much to boot. I wonder which of the new AM5 motherboards can do 8000 most reliably...?
A starting point for which X870 Mobos might work well could be the chart from Hardware Unboxed in the X870 roundup video. He did test what the highest clocks are he could do with each board. I don't think he did fiddle with any voltages and just ran a quick stability test, but it should give an indication which board may be the better ones for higher clocks.
Also the voltages are sometimes named different things. I had to go hunting for that a while ago (and I've forgotten what's what) and found a vagely informative block diagram that kind of explained it.
9:51 "This video is gonna be a disorganised mess" and we'll love it for this! ❤❤❤❤
yo BC thank u alot for all your effort in your videos, all i wanna say is i just simply love your content and u also a very wholesome dude to vibe in streams with
Thank you for sharing your experience with us
How safe is 1.3v soc for 24/7 use?
@@Markknightexeter Upper limit, its fine. You dont need 1.3 soc for 6000 anyway. 1.15 or even 1.2 will work.
@@frequencycs thanks, I was thinking of starting off trying to get 6400 1:1 to start with, still saving up for a CPU, got the ram and motherboard though 😀
@@Markknightexeter ya bro if u can do 6400 1:1 then you are very good. You will need 1.3 for that and 1.4 for the vddio. Always depends but thats the ballpark.
Good luck!
@@frequencycs that's what I was wondering, I might just try for 6200 in that case, thanks again
Perfect timing! Was just mulling over a couple kits for when the 9800x3d drops
which kit have you decided on? I'm also looking for ram for the 9800x3d and im narrowing at the trident z neo 6000mhz (cl30-40-40-96) or corsair vengeance 6400mhz (cl 32-40-40-86).
BUT Gskill is marketing AMD expo and Corsair Intel xmp, is this just words in the wind or do they have an impact?
Fabulous guide! I've been wanting to understand this stuff for a while now and didn't find good information. This guide clears up so much. After watching this I realized my 2x48GB 6400 is running 2:1 mode, so I reduced it to 6000 and set it to 1:1 mode. I stress tested in Prime95. Running stable and faster now.
I was just wondering about this few days ago! Tnx for posting this here so we can all learn about it!
Been on DDR4 xmp so long. This is a godsend for tuning my frist kit of ddr5 for 9800X3D
finally a new asmr from Buildzoid
This was an awesome video, really appreciate it!
The best video! We need more of this
I gotta say, I really appreciate these videos. Thank you!
Very useful, thank you. 7900x/TUF 670E. Gained 1% in R23, 3% in Civ6. 6200 cl30, 2200 fclk from 6000/2000. Auto voltages. Wouldn't do cl28 or 6400 with everything cranked. Will see if performance increases dropping the fclk to 2100 to hit 3:2.
Very good video, thanks for the really clear explanation!!!! ❤
Thanks, this is a great lesson on infinite fabric on the new AMD CPUs
For flight sims in VR, I was thinking of just getting a 2x48GB 6000 CL30 kit.
But having watched this, now I'm wondering about trying a 2x24GB 8000 CL38 kit (on MSI Carbon x870e board with 9800X3D) and doing the 4000 2000 2000 thing.
My main question: will I spend more time trying to get it stable than flying planes?
I saw data that 8000 CL38 achieves quite significant gains for MSFS, and that's the way I'm planning to go for my future setup
Really helpful, truly the guide I needed!
Also wanted to ask, is it even worth it to try & run 7800MHz RAM speed on a 7800X3D? I recall you mentioning high RAM speeds on single CCD chips being pointless because the Infinity Fabric can't handle that much throughput because it's very narrow. Asking because I kinda want to know if my RAM can run it, because I am planning to upgrade to a 9950X3D when they come out (because I need the cores for workloads I'm running when not gaming). Currently I know for a fact 8000MHz isn't happening, I've tried it all the way up to 1.55v with CL all the way up to 40 and it just will not train.
depending on the game it might be a bit faster than a 1:1 6400 setup.
@@ActuallyHardcoreOverclocking I can't get 6400 to work thus far, best I've done is CL28 6200MHz with a 2066 FCLK. Thanks for the reply 👍
Fantastic overview and explanation BZ. I guess one overlay to this is also density and SR/DR DIMMs? All the 8000 kits seem to be lower capacity up to say 2x24GB. As you push 64GB and 96GB kits I presume the memory controller has even more to contend with so the lower MCLK and UCLK rates would be preferable or even just straight up feasible?
yeah DR sticks introduce more signalling challenges.
What drawing program do you use? Also love your vids, I can't ask for more.
@@DuckyQuackBoi GIMP
36:02 RAM takes forever, wire length doesnt matter.
best part in the video so far.
Thanks for the great info BZ
Question: do you expect there to be any benefit for AM5 if/when CUDIMM support arrives? Haven't had time to listen to the whole video but the question popped up in my mind. Would an external clock chip on the DIMM allow the memory controller to push above 6000/6400 MT/s (in 1:1) or get even tighter timings?
Of course I have subscribed to your channel, so I will look forward to see if us potential AM5 buyers should wait for the newer standard or snag a deal for regular DDR5😊
I'd like to see the answer to this one as well.
Cu-dimm will work only in bypass mode - clock driver won't be used, so AM5 system would boot with cu-dimm but there wouldn't be any gains. CKD improves signal integrity so ram speed can be pushed higher, but Infinity fabric is already saturated.
PS. Signal Integrity is not issue on AM5 the more Ryzen APU that can drive 8000-9000 MT/s on cheap boards. Only UMC on chipset CPU has to be improved - support ddr fgr mode etc
amazing!! i love this videos, a like for you my friend!!
Thank you for another great video! What motherboards would you recommend for 8000Mhz? :)
x870e aorus pro can handle 8200mt like nothing.
Great video! You could also make one about Intel 12th, 13th and 14th Gen, they are very similar.
Thanks for this bro much appreciated 👍
Regarding 600 chipsets doing high frequencies: my ASRock Phantom Gaming B650I runs 8000 with a 8700G and my ASUS B650E-I boards can do 7800 with a 9700X. So for anyone shopping, those seem to be capable options (ASUS was also fairly easy to setup the 1950 IF mentioned).
just found this channel - does there happen to be a written guide (by buildzoid bro or not) that i can read as an intro to OC?
coming from the 2023 dec ddr5 vid and now a bit lost.. 😊
Actually my "loaner" 7700 I bought while my RMA of 7950X was being handled can handle 3.2 GHz UCLK. When I disable iGPU but run all PCI-E lanes occupied (VGA, all lanes for SSDs also occupied) then I passed 12 hours in OCCT memory with 1.215 VSoC, so while it is not golden sample, it is decent piece. I tried it as I got 6400 MT/s kit from AliExpress if my CPU could do that as well as I assumed newer AGESA releases could help. And when I grabbed EXPO profile with 6400 MT/s it POSTed (most EXPO profiles will dial in automatically 1.25 VSoC). Then I started looking for safe lower voltage and later found that 1.215 VSoC will pass the test suite I throw on it (OCCT Memory, Y-Cruncher and Prime95 Large FFTs)
On the other my 7950X pre-failure needed at least 1.155 VSoC to run just 3 GHz UCLK and 1.275 VSoC for 3.1 GHz UCLK. I am looking forward for how much will handle my future upgrade 9800X3D
Amazing video.
I'd love a video like this about Ryzen 8000 APUs and also dual rank hynix A-die DDR5 for those of us that unfortunately need the extra capacity (what you said on you dual rank hynix m-die video is also true for dual rank a-die?)
I was also curious about an 8000 video, but Buildzoid replied to me he thinks it’s a ‘potato CPU’ so I highly doubt it.
@@kasimirdenhertog3516That's a shame.
When the GPU market became 100% insane I decided not to own a discrete GPU ever again. My iGPU will be lagging 6-8 years but I haven't regretted it one bit.
Less power, less noise, less space and good prices. It is a win-win-win-win for me.
@@spamlucal I’ve got a 8700G and I think it’s a great little chip. It runs very efficiently, especially at idle/low load, and has a great memory controller and quite a bit of overclocking headroom. For instance, it runs 2400 MHz Infinity Fabric no sweat, whereas 7000 (and 9000, same IOD) chips can just about crack 2200 MHz - if you’re lucky. With a bit of tuning, performance is on par with a 7700X while running cooler, quieter and it packs a beefy iGPU to boot!
Out of 5 pieces of 9950X I've already assembled (15 more to go from current batch), I have one piece that required 1,25V SoC for just 3,0GHz of UCLK. Some CPUs just really sucks.
As I do assemble these for max stability, I usually set VSoC to 1,2-1,25V, I really hope that's not too high for 24/7 simulation usecases.
Thanks for information about FCLK bug fix in newer AGESAs, I'll use 2100MHz instead of 2033MHz now.
I have a Gigabyte B650 Aorus Ultra still on F3 bios. Still use the 2033 FCLK but on my newer one I use 2100. since it's on F9 bios.
Yeah, ryzem mem controllers are all over the place. I had 2 7700s which couldn't manage 6000mt on 1.3 volts soc. One of them was stable-ish at 1.3 the other had to be lowered to 5600mt. A third one basically died after being run on 6200mt at 1.3 volts.
Great vid! 😎
My PC has been running for 96+ hours streaming at 3000,1500, 2000. I shut it off finally and enabled the ULK=MCLK.
b/w yourself & De8uer's info... I've been running 128GB of GSkill NEO at 6000 CL28 on my daily driver (7900X). not hard - certainly not impossible
What model ram do you use?
Great vid, ty
I can't get 8000 to work on the X870E Hero. Supposedly there's going to be a BIOS that helps but I've not got my hands on it yet.
Great video many thanks
I have b650e taiche, and it gave very good overclock potential with ddr5 and all. I play CS2 in very competitive way, and have, 280hz monitor, 1000hz mouse. I play very good, and can notice very little input lag on overclocked system. So I start to search for best bios settings for lowering input lag.
I was playing on AM5 DDR5 6400ddr cl30 about month on fclk2200, and it works. But when I CMOS my bios, and it works with default settings by motherboard, it works with best precision of mouse, not like with fclk2200. My overclocked config goes through all testmem, and occt tests without problems, but I goes to 2133 and I have much better mouse precision on that fclk, then with 2200. So I played about last week with that bios config, and now I saw your video. Very nice 👍
Next round I will try to turn off PBO...
Next try to lowering vsoc from 1.25v, to 1.2v but I have errors on occt processor test, maybe It's not vsoc problem.
And try ddr7600 and ddr7800 mode, because of your explanation of lower latency mode.
I have question for author, where you find information that on 7600mhz with if 1900 there is synchronization and it will be more good for games? I want to find proof of information, not only words.
Update: 26.10 I started with ddr5 7600mhz and it works on my a-die vddp 1.15, vsoc 1.15, vdd 1.45, vddq1.45, vddio 1.3!!
This guy has years of experience lol and as he said in some Szenarios btw. probably your 2200 just isn't stable..
@@dankingofbull8997yes I know about that moment, but I used all tests that I can get for IF. Cryncher VT3, Aida Photoworks, Occt CPU+RAM... And it's stable, as I sad taichi is very good plate with good overclocked potential, so everything works very stable as it can be in 8 layers plate.
After video I try to get stable work on 7800mhz cl36 vdd1.4, and it works, but memory latency 58.1 vs 55 on 6400mhz.
I tried it in CS2 and maybe it's placebo, but it's works good.
I downloaded cs2 benchmark and will try to make some fps results in 7800vs6400.
I noticed in ddr7800 more fps in that game, I want to have fact numbers.
His word is the proof
@@rdmz135 I talk with experienced overclockers in special forum, where only proof can work ;) I want to share this with them and discuss.
thanks for the vid, i didn't know anything about ram oc before watching this lol. you think these values will shift much with zen 5 x3d, maybe there will be imc/fabric improvements? i was thinking of getting a 9800x3d and pushing it to its max in gear 1, but if there are no substantial improvements then why not just go 8000mhz+ and fully take advantage of x870 mclk
useful as always, thanks!
Thank you for this
52:12 I love potato chips!
*EDIT I've seen reviews of X870E motherboards now with a G-Skill 32GB 8000Mhz CL38 kit that actually "just worked" with AMD EXPO. So maybe a 8000MHz CL38 memory kit that is on the QVL for your X870E motherboard combined with a 9800X3d (or any 9000-series) wont be a bad purchase then :D
Because they run at 2:1 ratio.
8000 ram 2000 uclk and 2000 fclk
@@stormrider01 Sounds nice! But ofc paying for a performance you could tune into yourself instead.
Just recently purchased Gigabyte X870 Elite wifi with 9800x3d and GSkill Neo Z5 8000 2x24g CL 40-48-48, 1.35V @ 2:1 ratio 2000uclk and 2000fclk with XMP enabled worked straight out the box 24hour Mem86 stress test no errors.
@@Tracerlink I endedup with the ASUS X870E Hero and G.Skill 8000 2x32 CL38 and it works like a charm with EXPO! But where u found the 48GB kit? There where no in stock anywhere for me so had to go with the 32GB kit. Maybe I replace them in the future and sell the 32GB kit. But it's ok for now I guess.
Awesome content, great!
Here I am enjoying the info and being just boring and going stability above all else, and sticking at 5200, because I need capacity more than speed. Lost to many files to the wrong RAM in the 1990s, from tin on gold contacts. My question is how good is Gigabyte's RAM sub timing optimization since it seems to be very aggressive from what I have read. Thank you for the videos they have really helped me understand my computer.
25:05 lol error correction every ten minutes is amazing, on my zen3 IF is stable at 1833, but at 1866 it just spams corrected error events every few seconds
In my testing, this video doesn't apply to 2x32GB modules, the best I could get is 5600MT/s with FCLK 2200, with MLB5C640A77P32GX2
It would be helpful if you could define more of the acronyms as you encounter them in the diagram and during your video. I know many of them at this point, but not (for example) what CAD stands for. The meaning and purpose of various important timings and impedances somewhat escapes me. The voltages seem especially important, so I would try to summarize them up front as much as is feasible. Thanks.
Really wish amd would improve their IOD. Starting to feel like it's really holding them back. What if they used the epyc IOD? Idk if that's even possible. In my head it would make sense to move them closer for signal integrity, maybe something like intels doing where it's on top of a base substrate that can carry the signal faster?
High Yield speculated on the future packaging of Zen 6, and he figures the most likely answer is that they'll move to using something called an organic RDL interconnect. th-cam.com/video/ex_gPeWVAo0/w-d-xo.html
Having QVL for Memory is the first time I am seriously looking on AMD's boards
Stabilizing 7000 series with non-QVL ram is rough, and sometimes even with QVL ram doesn't stay stable
Ryzen is super voltage sensitive, you are still stable, but you will get lower 0.1% and 1% lows, sometimes as much as 10-15 fps just from changing SOC from 1.25v to 1.24v
You will crash in games if you are undervolting GPU a bit too much and it will happen on 7000 and 9000 Ryzen, I really could not figure it out at first, because that undervolt was stable for 2 years with Intel 13900k, long story short I realized that everything in AMD CPUs that has to do with voltage can affect your performance negatively if you add undervolt. Sometimes as little as -10 Curve Optimizer will cause worse performance, and I tried it with 7 AMD chips 7000 and 9000 series
Before RMA-ing parts, turn stuff to stock voltages and see if it goes away. It is how sensitive AMD is to voltage, but Intel doesn't care as much about voltages, you seem to benefit more from undervolting than overclocking on Intel
If you are struggling with blue screen and game crashes, change stuff to stock voltages for each part and slowly test it for next week, then start changing undervolts on each part.
Trust me, it will make more sense than changing parts over and over
So which Ram to get for 9800x3d and asus rog x870e-e ? Is corsair dominator titanium 7200 cl 34 better than 6000 c30?
while this video I tried switching from 6000, 2033 fclk to 6200, 2066 fclk. This should be definitely be better but my SOTR benchmarks went significantly lower. So that's fun. I'll guess I'll try some other configs
Could you make a video to recommend your favorite motherboards and just good motherboards for Ram overclocking?
thx
Exccelent video. I want to see how much more I can push my CPU. I am currently running a 9700X with 6400MT DDR5. So, 3200Mhz MCLK, 3200 UCLK and 2000 FCLK with 1.3v SOC. I wanna see how low I can go on the SOC voltage as well as how much more FCLK I can get. I think 2033 is stable for me but I dont think ill get it to 2133.
Errr... I might have a unicorn.... My IF is at 2233 right meow and I cant say if its 100% stable yet but R23 ran, Prime95 ran. Got toasty on the CB run at 94c... More testing needed. Bench scores seem fine. System hasnt been hitching and stalling out on me... YET.
@Seansmit23 find where FCLK boots but is very obviously unstable, then go down 2 settings. That's the lazy easy way to find a probably stable max FCLK
At 1:1 mode, 6000 cl28 is better than 6400 cl30 for esports gaming?
has something changed with the last couple AGESAs? the newer they got the worse my FCLK OC gets.
some pre 1.2.X.X Version were all fine at 2166 with stock SoC of 1.25V and +50mv on both VDDGs (900mv)
now i can barely post 2166 at 1.15V SoC and up to 1V VDDG. 2133 is the absolute limit on both my launch week 7950X and 7800X3D from early 2024.
I find the original 0805 bios for my proart x670e is the best for my memory oc. Newer ones very hard to get anything stable
My Ryzen 7800x3d is paired with a DDR5 6000 CL30 and can do up to 2133 FCLK with no issues but I reduced it to 2000 because it’s divisible by 3 so I thought it will be better , basically you said that if I go back to 2133 actually will be even better ! 😅
I really want to know what the actual cause for „VSoC up = FCLK down“ is.
Some comments from an 8600g owner. It can run 7600-7800 plug&play-ish with auto timings and 1.15 vdd_soc, however I simply cannot get it to work at 6200 1:1 at all 😂. Also with vdd_soc more than 1.15-1.16 something happens to iGPU (driver fails, my guess here) very fast after booting into windows and screen turns grey, which renders all expo profiles unusable. I've seen many complaints about it over the internet, I wonder why AMD does not do anything about it. Also FCLK runs 2400 no problem.
the APUs use a different memory controller and different IF design.
I have a hp laptop, 8 years old now that I managed to increase its RAM to 16GB, DDR4. I simply bought another DDR4 8GB DIMM and put it in the empty slot for memory channel 1 I had had for all those years. I was careful to buy a DIMM with same frequency as my old, 1066MHz. I then ran CPU-Z for the first time and realised that the DIMM my laptop came with all those years ago was generic. No manufacturer information shows on CPU-Z and the memory chips have "Enfineon" branding which I think is a ripoff of the Infineon brand. Still, this is the DIMM that has served me all this time with no issues. To increase my memory, I bought an 8GB DIMM which has Micron chips and on CPU-Z, manufacturer information shows about this new DIMM unlike the old. Both DIMMs have same specs. The older DIMM goes up to JEDEC 7 while the newer one upto JEDEC 9 on CPU-Z. I am assuming therefore that the memory controllers will default to JEDEC 7 for both. The JEDEC 7 specs of both all match except the tRC. The older, generic DIMM has tRC value of 51 while the new Micron one has 50. Is this a problem?
Would love if you also did a video on impedance settings, very hard to find any info on them
I watched through the whole thing, I think I understand the relationships between the numbers but coming from inexperience I don’t know how this translates into actually figuring out what the optimal setup is for a chip, like step-by-step. Or how to get a feasible list of configurations I can try out. Like I don’t want to buy a memory kit only to find I need another one.
I really only undervolted Intel laptop chips before so this is a bit more granular than I’ve dealt with before. I think now that a new wave of people are taking AMD seriously after this disastrous Intel launch, it would be good to have a more cut down guide that goes through things in the order they’d be done for a stable system setup? Like pushing that voltage to 1.3, figuring how high this setting goes as a priority in this ratio, figuring how high it goes in that ratio, and kind of the math involved in picking the best option.
Like I wouldn’t know what to prioritize here. Maybe the “optimal” settings here are just too power-hungry, and I want the best settings for a certain efficiency.
Again, I come from the laptop undervolting world where sometimes “worse” theoretical settings are better because they don’t hit power or temperature limits. So maybe I’m thinking of this the wrong way.
I have a Hyperx 5600 CL 36, supposedly Hynix M-die.
I'm running it stable at 6000MTs with Vsoc at 1.2, MOBO automatic, with your timings starting point guide.
Can't push it any further, even maxing Vsoc at 1.3 :(
The FCLK on my 7500F maxes out at 2206.6MHz with a 100.3 BCLK OC. I will cry myself to sleep😭
nice work
so i woke up on saturday and watched this vid
2 months in my system is still not properly tested, i tried to figure out what should be done to get 6200 going once, ended up clearing cmos and rolling back to 6000 xD
but after watching this video, i got curious, whats the min vsoc for the current 6000 setup.
well, 2 days later, i know - 1.16 - life is not fair =/ it seems to be ok at 1.1-1.13 at first glance, but if you leave testmem5 running long enough - errors are there. i guess 6200 is not happening for me.
thanks, BZ. thanks for the content and thanks for the motivation.
How do the most recent (if they change) "aggressive" timing preset compare to your easy hynix mem timings?
20:00 talking about 2 out of 4 Slots used or with all 4 Slots
what? hes not talking about that right?
Do you have examples of the audio glitches? The infrequent ones? Does it sound like a to audio buffer underrun? Asking for a friend 😅
Thank you, now I know a little bit more, maybe I will try some oc and get roasted on reaction stream 😂

To test UCLK, do you think VT3 is best?
Karhu or testmem5 should also work just fine. Too high UCLK is usually a pretty clean breaking point.
Just be aware that when AHO says "faster", what that actually means is faster by a tiny amount, in a specific workload and only if your system is actually stable running that faster clock/timing.
My 9950X system runs stable @ 6400/3200/2133 with 1,27v SoC, so i guess my chip is above average on silicon quality.
I would guess DDR5-6400 at about 1.25V SOC is average nowadays, though my sample size is small. Of my 4 CPUs, 3 of them do it. 4th one does DDR5-6200 at 1.2V SOC but can't stabilize 6400
@@atirta777 You'd need twice the silicon luck for dual CCD CPUs. Are your CPUs dual or single CCD?
@@techtechuw597 Twice the luck for the IMC in the single IOD? What do you mean exactly? My CPUs are single CCD so I'm probably not understanding something
@@atirta777 I may very well be wrong on this. I think the max fclk clocks are limited by the lesser capable CCD, because each CCD has its own control unit. Max mclk clock is probably limited by the quality of IOD only.
@@techtechuw597 Oh that's what I was confused about. Yeah IOD isn't affected by CCD count. The FCLK probably is, but that doesn't affect what you can run 1:1 at a given SOC voltage. UCLK (memory controller clock) is what the IOD is responsible of.
So do you still consider 8000 memory particularly difficult with the new X870 motherboards or have you not gotten to try it yet? Every single one has 8000+ kits on the QVL list.
Any plans to put the FX6300 that did 5.6 on air under LN2?
Im still trying to figure out to get my 7800x3d stable at cl28 6200 on a-die. Feel im close. Fclk at 2167 so that is good. It is probably the most I can get out of this system.
Low CAS latency is entirely dependent on setting the memory VDD voltage high enough. For 6200 CL28 I'd guess you'll need around 1.55V
I run 2000 FCLK bc those audio cut outs are soo annoying
Are there FCLK holes like they were on AM4? e.g. My chip could do 1900Mhz IF just fine but not 1800 1833, 1866. 1600-1800 could just fine.
Did anyone notice that the new x870 boards support up to 256GB of ram? Are we getting 32bit sticks?
MSI advertises almost all current boards as 256GB for some time now, but so far you can only buy memory sticks with 32Gb ICs as the registered ECC variant for servers. Consumers will probably have to wait till the demand for AI nonsense fizzles out.
32Gb mem chips have been in pre-production for a while now. Still no mass production AFAIK.
@@ActuallyHardcoreOverclocking Crucial/Micron sells 128GB reg. ECC modules (MTC40F2047S1RC56BR) based on 32Gb ICs for about $1200/€1300/£1100 each in their online shop. Seen them over here in Europe for €1500+ at retail as well😵😭
I thought Infinity Fabric Frequency was the same as FCLK so I set it to 2066 to match my FCLK of 2066 because I’m running 6200. So am I supposed to set Fabric Frequency to 3100 to match the UCLK?

@@jilhermethank you
I have 7600 + 4080s and proart x670e with 64g kit , hoping to get best out of it with your videos.
This is great reference
why a 7600 +4080s love proart but like why not better cpu/worse gpu to get better cpu
no hate❤
@@kkillertck8097playing at 4k is one reason
@@kkillertck8097 long story short, I stared with 7600 + a620m, sold this when I got a really good deal on proart+ 4080s, then i waited for 9000 series to get the cpu, expensive+ 7800x3d price up, i brought back another 7600 at way cheaper than what I had sold mine for .. now hopefully, 9800x3d when time is right.. until then, gotta do with 7600 and play around with overclocking/under
@@SeventhCircle77 I mean I guess that is one reason but I have a 13600k 6650 XT play on 2560x1440p and I still am CPU bottleneck and most of the games that I play Q FSR most of the time and not not fornut or val or not great fps
The CPU isn't a bottleneck it's complete BS, it'll be the game engine.
I think Borderlands 3 max fps is 365 didn't matter the CPU you have.
There's only so much stuff the game engine is going to do and games don't push a cou past 60% usage.
There's videos of cyberpunk and parts only have 30% cpu usage, so its idling 70% of the time.
The best for Ryzen 9000 and X870e MBs is: 8000 at 2:1 mode
Any chance we'll see an attempt at 8000 running 2:1 on the Tomahawk? 👀
what if MCLK is higher while UCLK and FCLK are the same on 5000 series? is there less of a penalty compared to full desync?
Watching this video is just confirming how dogshit my 7700x’s IMC is lol. Thanks BZ.
Any idea why my 7800X3D needs FCH spread spectrum enabled or else I get stutters in games? RMA the cpu?
14:22 My cpu needs 1.19 for 3000 it's really bad
Also I think it's infinity fabric is garbage too starting with 2100 becomes unstable
So i stuck to 3000:3000:2000 for now
I'll test 3600:3600:1800 when I get time
actually, i'm on 8000 with a Gene, and 2000 FCLK even though its synced, 2200 gives me better results overall ... so i prefer to keep it at 2200 FCLK.
running 1.15v VSOC ( i know i can go lower, since i tried it but didn't want to leave it like that until i fully test it )
1.30 VDDIO (need to test lower values, i starter with 1.35 and keep lowering until i had an issue, which i did not have, but was so tired of FAFO'ing that i left it there :D )
