your scores are already very good especially with AiO! That cooler is proper strong!

and in Ycrucncher too, you can run it realtime prio, and use a .bat file to make it run in REAL realtime prio for another couple hundreds, you can get to LN scores if you really really try! Also try 6600 in 1:1 mode with 2200 fclk for it, sometimes its almost half seconds faster as in 1:2 mode. Make a word documnet with this text: (and save as . bat)

wmic process where name="22-ZN4 ~ Kizuna.exe" CALL setpriority "Realtime"

and run it as admin after you press start in ycruncher to set in in realtime prio. This is the way Buildzoid had his topscore on YT couple months ago btw.

Neurotix, you have lots of headroom for those GPUPI benchmarks, you should at least set GPUPI to batch and reduction sizes 128 4, and disable IOL vectorizer. You will beat me in one run. And use this program: to mess with curve optimizer in windows. SMUdebugtool 1.3.2 . This is a nice start but you can get at least 0,2 seconds off!

Hey, some of you guys especially @kalizshould get on hwbot with these high memory speeds you're posting. Here's some benches to beat:

if i had a 12 core CPU i would try to beat that, 

the only benchmark you can compare is GPUPI 100M , i only have 6 and 8 core CPU's

So this Dom guy from overclock.net DDR5 forums was busy the whole day to beat it by 2 hundreds  so its a pretty sharp score

scroll a bit through my hwbot page and you see the specs on the screenshots, it can do 8200 C32-43-40-32-72 with 1.7v around that, havent tried much more yeah a 8360C34-46-46 really  should try more and tigten up with high clock. 

its surprizingly 'stable' i can open benchmate and do all kinds of benchmarks with over DDR5-8400. I wouldnt dare to run a stresstest becasuse i just upped the voltages to extreme level. I did try a normal voltage and tighter timings a few times and that also works just fine, but then again its only in benchmarks and not a stresstest. I could go browsing with 110 bclk and 8560 and upload a score to hwbot, pretty amazing

lol even the 8000 strap works for over 8600 wth!

you can also manually set TSME disabled (if you can find it, and for huge bandwidth increase you always want to have the optimal CPU curve optimizer , or at least close to optimal for max CPU boost in the test. or for non X3D set manula CPU OC!! I was trying for max clock on my 7800X3D and got DDR5-8580 just now with 110 bclk and 7800 strap! 

make sure your mobo and CPU have the latest chipset drivers and agesa it really helps to get things 'more stable' 

that was on a random Z690 MSI mobo, on AMD its also buried deep in settings! I will make a pic when i restart my PC!

the first one i got was great and fits perfectly, this one however doesnt even fit. Its too small cut out. Waste of 4 euro

i managed to get 6800 in 1:1 mode working even with max CPU clock in benchmarks. Not all benchmarks, allthough 7zip/Ycruncher gives an error halfway through so its not stable, but i havent seen this anywhere on hwbot, yet

Ye i saw that indeed. 

 

I think expo is better for if there are any issues i can always revert back to expo settings that work but maybe that is the lazy/faulty way lol. 

I want stability for mostly gaming. 

 

I was tweaking on my previous system which was an AMD 5600x with FlareX 3200MHz RAM tweaked to 3600 MHz lol. 

So i am not an total noob but definetaly A LOT to learn about DDR5 xD. 

 

Thnx for the help, much obliged! 

Hey Richard, i would suggest going with a Hynix A-die kit, for example this one (i made review about on Tweakers.net)  This set has XMP profile which also works flawlessly on AM5 platform with tight timings. Only thing you have to manually set is mem clk/ u clk in 1:1 mode, rest auto. This is the best you can get at the moment for under 130 euro.

Alright trying 8000mhz with the looser timing set that Orion gave me, 1.0v VDDG, and 1.1v VDDP. Doing memtestCL now. Wish me luck, but I do fully expect it to fail.

 

I think my problem with 8000mhz is that it might be cooling-related; I think you guys (kaliz and Orion) have fans pointed at your RAM, yes? In my case, with full RGB and matching RGB on the memory, I don't want a fan sitting on my GPU pointed at the RAM.

 

The interesting thing is that 8000mhz for me is benching stable: I ran Cinebench, y-cruncher and a few other demanding benches for my hwbot yesterday with the RAM at 8000, and it was fine. No Bsods, crashes in the programs or anything. I imagine it would probably be gaming stable too. However, since my rigs primary use case is a home server/streaming server, I cannot afford to have bad memory corrupt files over time, especially on obscure 80s anime I wouldn't be able to download again.

most issues you have with AM5 platform is RAM training. One day you find a good stable setting, it plays all the games benchmarks and stesstests, and the next boot up you get lagspikes or errors. Really crazy.

I now have set Powerdown enabled, this seem to help, and memory context restore disabled, so that every time you warm reboot, the ram retrains. If that doesnt work, loading a profile, reboot, shut down system, turn off PSU completely, wait a bit and restart PC so it cold boots with your previously stable settings. Really annoying but if i wanna play BF2042 i do it like this. Then my 8000C32-44 profile with 1,70v is stable, or a 8000C34-45 profile with 1,62v. I always use a fan to DDR5 it gets really warm even on lower voltage. Specially the G.Skill modules, they dont have a thermal pad on PMIC and the heatsink arent great. If i dont use a ram fan i have seen 80C+ with TM5, and also with gameing when GPU heats up. Errors occurs at 50C+ sometimes even 45C+ and thats pretty easy to reach

make sure to set memory context restore to disabled , with this 1.0.0.7 b and c Agesa you will get training issues! AMD is on it to fix it with 1.0.0.8.

VDDG's auto are 0,850v , they are safe daily up to 1,1v. Ive set mine to VDDG CCD 1,050 and VDDG IOD 0,950 just as i did with Ryzen AM4 and it works for high FCLK speeds! Safe is up to 1,15 but anything over 1,05v is out of spec.

i screwed my OS by using 8000C32-34 the whoile day without knowing it, so now sometimes my browser hangs

o yeah those are single rank 2x24GB Hynix M-die modules, very nice stuff!

Is the TridentZ5 that I'm getting (I convinced her ) dual or single rank?

i couldnt find the part number if you posted it here, but if its 2x16GB or 2x24GB it is single rank, and 2x32gb most likely dual rank. Just as with DDR4 single rank clocks a bit better vs dual rank and has better latency.

Nice! 

 

Quick one as I have observed this a few times now, and your screenshot just reminded me. I note that you have RttNomWR & RttNomRd set to OFF. I assume that is based on your current OC/Memory module characteristics and not some general recommended setting ?

those two are only used for dual rank ram! 

also for the Nitro settings enabled enabled  2-3-1-8-8

And try tRDRDSC/DD and tWRWRSD/DD 8-8 10-10

Not much to add, @kaliz already got it covered better than I could. FYI, I keep V_SOC at below 1.26 V and VDDQ in the 1.3s and yeah, as already mentioned, either go to 1:1 for 6400 and below, or 1:2 for 7800 and higher

in 1:1 mode if set 6400 with 2133 fclk its 'synced' as in 3:2:3 (3200:2133:3200) If your CPU cannot handle 2133 you can set 6000 with 2000 fclk (and raise the bclk),  or 8000 with 2000 fclk in 1:2 mode (2:1:2) , the best CPU's do 6600 with 2200 fclk, or 8000 with 2200 fclk. a

here arent many more combination but this will help somekind of throughput dont know the name anymore. I like to use 8000 with either 2000 or 2200 fclk ( or 2133+ at least)
