Ok this is funny, I tried enabling ECO mode => all WHEA errors are gone, overall performance lower, but memory related results unaffected.

So how does it change my FCLK & voltages vs WHEA situation? Does it mean they are caused by:
  • overheating
  • lack of power, or other power management issues with PBO on auto (CPU SoC power still goes to around 20W, while power left for CPU is not hitting nowhere near 120W+ anymore)
  • else?

I can live with that waiting for BIOS update.

dont know if it matters that i do have synapse software, afterburner and a few other apps running in the background but this is without GDM with one change to tRFC and the mentioned GDM being off and still in 1T. and passing 10 runs of tm5 . ive found that with these chips (teamgroups 3200mhz c14 kit, that within the third run errors pop up if its unstable cant say thats 100% always the case but so far everything that wasnt stable that brought errors did.

Samsung C die @3800 FCLK 1900 UCLK 1900 working in progress
ive got a set of lpx 2x8 kit with c die GOD forbid me from sticking that back into my system again. or at least thats what someone told me on buildzoids channel and is why i had such a hard time with the kit posting at XMP at all... (CMK16GX4M2D3600C18) is the kit. 4.32 is the version number which is where C die came into play.

I've got 3200 4.32 and I know how hard to set it, but I can't spent more money in a ram, here the b-die can cost as a 3300x


The G. Skill work better and they are amd certificate 😂😂😂. I love old school oc

Hi all, I've a set of 4x8Gb 3200c14 B-Die and this is my situation at 1.41v DRAM, no CPU OC or PBO tweak.

2467163


Is there more to squeez out of this set at this voltage? What should I consider to test?

The system right now is stable but now and then I hear an audio crack. Seems I delayed it by happening rising VDDG IOD but I'm not entirely sure It's the right parameter to tweak, any suggestions?

Hi there, a noob question. How stable are higher FCLKs for you? I'm not asking about TM5, or Prime95 like stuff as it never crashes for me at 1900 but about these annoying WHEA 19 warnings. I had zero crashes or issues since I build my set (5800X Asus TUF B550 board, 1212 and 1216 BIOS) but heavy load like Prime95 or OCCT will make WHEA 19 warning appear. Tried to tweak voltages up and down without great success. I can make things worse and get WHEA while idle, but I was never able to get rid of them entirely.

Timings and voltages attached. AIDA64 performance is where I want to be (unless they patch AGESA so much I'm able to stabilize FLCK at 2000MHz)

What voltage are you pumping for the RAM itself?
Thanks for sharing your results.

considering i literally bought teamgroup DARKZa 4000mhz not paying attention X2 yes thats right 4 sticks 32gb 8gb sticks (which is C/Djr not to sure) not good for the price over the 3600 kit) and this c die kit as well as the 3200c14 bdie kit which im running now which TM5 with anta777 extreme profile has been going for around an hour and 26 minutes now with 3800mhz with one change from the screenshot above to timings and that being 16,15,15,15,32,38 trfc288 ect and the rest pretty much the same as before so pretty much just went from 3600 to 3800 and slightly loosened the timings with the same voltage @1.4v so far stable. point is ill be sending all the others back except for one of the 4000mhz kits to amazon...after tallying up what ive spent in ram this past week alone i could have literally got a third 3600XT before the price went ******edly high again (bought one got the 2nd free amazon made a mistake claiming i hadnt recieved the 1st one when i clearly sent them picks showing it in my hands but they insisted i take it and keep my mouth shut so thats what i did)... considering i have an old set of 2400mhz c14 TLred from teamgroup with J die, clocks to 3200mhz c16 pretty easy, and hyperX3466 kit j die i believe which was my best kit up till three days ago... for the cost difference it very well still may be my best kit lol....im currently working 12hours a day..well night and 6 days a week so money at this time isnt an issue...

if you lived closer id simply give this cdie kit to you so i could see it be used instead of being pawned off so someone believing that its amd ready like the listing says (checking corsairs website quickly shows its not)

just finished finally when i got done on my phone replying to you....perhaps at this time without anymore knowledge of what it is i should shoot for this is where ill stick too until i read a few more days on ram sub timings ect.... GDM was turned on and improved my aida score which swapped one timing from 14,15,15,32 to 16,15,15,32 ect. thats the only timing i seen swapped while using GDM...or then again perhaps ill see about getting a little tighter sub timings..perhaps that tfaw could use a cutting in half....

idk if this says anything or not but here is the hyperX kit i spoke of but that write speed is well...the best ive had yet....

Ram alone is 1.4V and it's passing all sort of memory focused tests so timings/voltage are fine.

I had just gotten WHEA errors under control when GB releases a new BIOS for the B550 Aorus Pro that fixes the 1900IF hard limit and I can now boot at up to 2000IF.
However even 1866IF spews out WHEA errors and 2000IF seems to need gear down mode enabled to boot so far.

Currently testing 4000 RAM 1800IF and that seem stable shame it performs like crap.
Will keep playing around to see if I can find any rhyme or reason to it.

Similar with Asus on current and previous BIOS. I can boot all the whay up to 2000 IF but gives me WHEA even at idle, and terrible performance it doesn't look like I could stabilize it with current BIOS.
1900 IF seems stable everywhere but heavy synthetic load like OCCT, Prime95, y-cruncher will eventually generate few WHEAs, one every few minutes. Here hope they are going to fix it.

You'll be always better with FLCK to MCLK ratio 1:1, so if best you can have is 1800IF then 3600 for RAM & go down with timings.

Okay, I've had this Ryzen 9 5950X for the past week or two and I've been struggling to get memory speeds in the same range as I had with my 3950X. AT present I have two sets of G-Skill Flare X DDR4 3200 CL14, thus 4 x 8GB sticks which in my old 3950X build I ran 3733 with FCLK and UCLK at 1866mhz. It was perfectly stable TM5 or Karhu memtest up to 20 000%. At present my system won't even boot if I set the memory, fclk or uclk at that speed. The highest I can go is 3600 CL16, 15, 15 30 1T and it is stable.

I did run 3800 with 1900 fclk and uclk with only two sticks but for some reason Aida64 latency was like 85.

After spending the day tweaking the RAM in the new BIOS this is where it is at.
1986IF 3973c16 1.49v set (1.5-1.512v reported) 52.2ns
I am just ignoring the 1500 WHEA errors in HWiNFO for now.
VSOC ect. are all tuned to there lower limits.
TRCD could go a notch lower if I removed the one dud stick.

after random restarts no error codes no bsod, i finally got stable with this. any suggestions or does this look "good enough for daily driven" dram voltage is 1.41 llc is at 2 which is flatlined on my board...perhaps all msi boards? HCI also passed overnight without errors.
also why is zen + write speeds so much greater than zen 2? can someone explain? same ram speed only quite a bit looser timings on zen+ over zen 2 (1600af specifically) ALSO how are you guys getting hwinfo to show errors? all i can see in errors in windows errors which always stays at 0 until i start killing stuff in task man for benchmarks.....??

This is a 2x16GB kit of Hynix CJR-VKC (according to Taiphoon) so possible DJR.

I am running it at 1.32-1.33V because it is ungodly hot once overvolted at all. It would however do CL17 at these timings with 1.38V.

As it is I'm quite satisfied by these results, but I'm interested is a second pair of eyes, is there anything in the secondary or tertiary timings that I've missed or am doing wrong?

tCWL will fail at 14 and yes I realize tRC should have been 59, oops.

Thank you :)

Hi
I have a question or 2
A friend is setting up a new PC with a 5600x, B550 Aorus Master and some G.Skill Trident Z RGB F4-3200C14D-16GTZR 16GB (2x8GB) DDR4, 3200MHz, 14-14-14-34, 1.35v
Is this a good choice of memory for the platform compared to the Neo and what overclock would he expect to get easily?
Cheers
I should add that he hasn't overclocked memory for a very long time and doesn't want to spend too much time learning but will follow some simple steps :)
I haven't done anything with AMD yet but it looks like the time is near :p
