This is FCLK-ing awesome

[@Brodda-Syd]

YES IT IS!!!

[@Sarajiel]

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 🤣

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...?

[@Hugh_I]

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.

@@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!

[@_scott_chegg]

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.

[@kasimirdenhertog3516]

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).

[@Iscandelt]

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.

[@PadPoet]

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.

[@marcopazzi117]

Very good video, thanks for the really clear explanation!!!! ❤

[@LOLHoneybadger]

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.

[@ActuallyHardcoreOverclocking]

depending on the game it might be a bit faster than a 1:1 6400 setup.

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.

[@frzen]

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

[@Matty-rn5gt]

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?

[@ActuallyHardcoreOverclocking]

yeah DR sticks introduce more signalling challenges.

[@stennan]

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😊

[@Meticulate826]

I'd like to see the answer to this one as well.

[@altynspiryt1039]

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

[@EndUser-yu7gg]

I must be lucky as my 9900x i push 6400 memory without a hitch.... 1.35V stock but i run the hero tweaked profile... So maybe the production of 9000 series is better and the hero memory slots with shielding cleans it up... Makes me want ti try 8000 memory just because...

I dunno how many people are watching this well after the upload date; Had to test this out on my system, which is the 9800x3d, Asus X870E-E, and a G.Skill 6400mhz cl32 ram kit, and it hits the magic number of 3200 1:1 ratio at 2133. Stock timings were 32-39-39-102. Running 39-39-80 seems to work just fine. Being a recently built system, I was having memory issues before tweaking anything, and after even just a little bit of tuning, my system seems to play real nicely with that setup. I'm not sure about bringing voltages down, because stock spec is 1.4v, and I'm rather new to all of this. But further testing will be conducted.

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.

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.

Good stuff. I wish I could figure out why my 9800X3D with 6000 cl30 RAM is stubbornly sitting at 1990ish FCLK, and 2960ish UCLK. I've set FCLK manually to 2000 and HWINFO still reports 1990.

I hope I can get a comment here but what does BZ mean by "not working"? Doesn't pass a stress test or will not boot? What does BZ use to stress test the UCLK?

[@Meticulate826]

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.

[@brzroman]

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.

[@lucaskelinohermansino4730]

So for a 7800X3D with 6000MHz CL 30, what would be the best setup for low frametimes? 6200 MCLK3100/UCLK3100 FCLK 2100/2133/2166 ? Or should i push further ? Temps are fine, i just want a stable low latency, low frametime system… help a bro out ! Great video

[@PuscH311]

What board for 8000 ?

[@WillFuI]

Thank you for this

[@shishinamys]

Please tell me what FCLK values ​​can be set at 6200 cl28 (1:1)? Thx.

Great video! You could also make one about Intel 12th, 13th and 14th Gen, they are very similar.

[@WillFuI]

Did anyone notice that the new x870 boards support up to 256GB of ram? Are we getting 32bit sticks?

[@Sarajiel]

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.

[@ActuallyHardcoreOverclocking]

32Gb mem chips have been in pre-production for a while now. Still no mass production AFAIK.

[@Sarajiel]

@@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😵😭

Full instrumental on your channel soon?

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!!

[@dankingofbull8997]

This guy has years of experience lol and as he said in some Szenarios btw. probably your 2200 just isn't stable..

[@K1-mf7un]

​​​@@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.

[@rdmz135]

His word is the proof

[@K1-mf7un]

@@rdmz135 I talk with experienced overclockers in special forum, where only proof can work ;) I want to share this with them and discuss.

[@IIHydraII]

Error correction. FCLK can be unstable without throwing errors in stress tests.

[@BasilHamdouni]

thanks a lot pal for video but its look so long to watch video can some one shortcut and tell me witch ram should i buy? for 9800x3d with board x87e asus , thanks a lot and please i need high end

[@IoNoobMaster]

In the whole 58 minutes of the thing (did I just watch a 58 min rambling about RAM?), I'm not sure I got this right and someone should correct me if I'm wrong. Basically, if you have Hynix memory that has 6000 expo, you should be able to do 6400 if the CPU can handle the 3200 UCLK?

[@jkd4568]

can someone explain to me why you would want you infinity fabric synchronised? what benefits does it give? also, what's the point of the DDR PHY? so should my OC order be Timings, UCLK, then FCLK? trying to wrap my head around how all of this works 😭🤣

[@IIHydraII]

Tyvm ❤ To test UCLK, do you think VT3 is best?

[@ActuallyHardcoreOverclocking]

Karhu or testmem5 should also work just fine. Too high UCLK is usually a pretty clean breaking point.

[@OptimizingNetwork]

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

[@a.pelayo_19]

Are these examples assuming you are running 2 sticks of RAM? Or 4? Noob here.
