I generally ignore QVL lists for RAM. Memory IC's are made by a handful of big companies (Samsung, Micron, Hynix e.t.c).

I purchased: https://www.amazon.co.uk/Gskill-F4-3600-%C2%B0C17Q2-128GTZR-DDR4-128-GB-Memory-Grey/dp/B073VPCHSQ due to the great timings and binning by Gskill. According to Typhoon burner my ram is Hynix DJR, 1 step off the commonly accepted best Samsung b-die, however DJR can run with more stability at higher temperatures than B-die.

I can run all 128gb at 3600mhz @ 16, 16, 19, 20, 32 (@ 1:1 infinity fabric ratio) completely stable after using Ryzen DRAM calculator by 1usmus.

Can you ELI5 the bold part ?

Does it mean you bought this kit and you plan to somehow manually change the timings or the voltage for your RAM or do you plan to use it 'as is" ?
I ask you this question cause RAM choice is for me the hardest part, and i'm starting to look around for my next 3990 build (plan to get aorus xtreme)

Thanks !:!

Hi guys.
I want to build a new pc with the 3990 x. Starting to get info soon. If you have kinda working builds with this cpu, would be nice to share.
Thanks !!

i stumbled on the same problem

it seems that when i open the cxr the gamme is wrong . If in the lightmix panel i pu tanother value in the hdri then re enter the original value, then it becomes magically correct...perhaps itll help someone....

I 'm a bit afraid to overclock and burn my MB/CPU. Isn't it dangerous (overheat and crash/burn/die ?) ? doesn't it reduce the components lifespan ?

I 'm  using Noctua NH u14s with double mounted fan to cool my system.
I' m curious about other idle and "loaded" temps with  solutions like wraithripper, enermax, or custom.

my Tdies are :  idle 28-29 C  and loaded 48-49 C . Room temp is 20 C.

(I assumed you just wrongly worded your question, but you are asking about stable memory frequency right ? That is when that number comes from. Not CPU frequency).

yes i was talking about memory frequency.

Thanks for your answer.

Excuse me, I see in this thread multiple mentions of how 2933 is for the moment the highest stable freq for 2990wx but I can't find this info elsewhere.
Where does the info come from ?

Thank you

edit: i found https://en.wikichip.org/wiki/amd/ryzen_threadripper/2990wx

nice infos.
perhaps i can do the same if i take noctua u14s and add an additional NF-A15 PWM fan :)
I think i will do the same as you do with RAM and buy 64 more at a later date to limit brokitude.

again thanks for your help.

There is link to single benchmark in the big thread, but I have to say that is some low quality benchmarking... doesn't really tell anything.
Looks like it doesn't provide much improvement compared to the Noctua, but I have some doubts as the heatsinks are bigger and it has more heatpipes.

I would personally give preference to the Silver Arrow as well. You can mount additional fan easily using brackets or some home-made magic :- ). The default is so loud because it's 3000RPM fan, while Noctua uses 1500RPM. You can even replace the fans with the same combo that NH-D15 is using, by adding one Noctua Sterrox 120mm fan.

I forgot to ask.
If i take the same RAM kit as James for example (or any 64Gb kit), will it be ok to buy the same kit later to upgrade to 128 or will i have to replace all ?
thanks

Nice build from James :- ). Wouldn't change anything about it at all !

Double co-sign under the 1000W+ PSUs. It's both good to have PSU running at lower capacity and to have leeway. Additional bonus is the PSU will be more silent as it can run in semi-passive mode.

Hi Juraj,
Do you think Silver Arrow is superior to NOCTUANH U14S TR4‑SP3 ?
Thanks

I just finished my build a few weeks ago and this is what I got.

2990wx
Thermalright Silver Arrow TR4 CPU cooler- I added a 2nd fan to keep the noise down because at 100% it sounds like an aircraft taking off. Both are running at 50% and are quite.
Msi meg x399 creation (latest beta bios thats floating around msi forums)
Flare x 2933 CL14 (F4-2933C14Q-64GFX) 64gb 4x16
1080TI
1300W SEASONIC Prime ultra 80plus platinum
500GB Samsung 970 EVO M.2 NVMe SSD

I had an issue with the pc not turning on once it was uplugged from the wall but that was just a setting in the bios. Everything worked well together though and it has been working great now for a few weeks!

I would get at least a 1000w psu, My 2990wx is using almost 400w by itself when rendering using PBO.

Hope that helps.

thanks a lot !
I haven't had time to look all in detail yet, but good tip on the PSU.  About the Silver Arrow and the second fan, I m a bit confused as to where you added your second fan.
Cool to see a stable build.
What case did you take ?

Last time I posted that i was trying to build a 4k workstation with 2990wx and 128Gb for corona renders mostly.

Obviously I am for the moment beyond 4k and id like to minimize the price and optimize if possible.  But the main subject is not doing a big beginner mistake in picking parts, since I havent built a workstation for a veryyyyy long time.
If you could just have an look at my temporary build and thell me what you think that would be nice.

here is the link to the build :

Makes me think because Xmp for 2933 appears to be working stable also there are no indications apart from absence in gigabytes listings that ram shouldn't do.
Off course before buying i checked qvl's there and there, and wasn't concerned this memory would create any performance drops(and doubting it is to be blamed) as it is advertised as high performance memory for x399 platforms.
Also reading from this thread psanitra has same memory in his build without any complains.

Yes perhaps memory is not to be blamed. Just noticed this little strangeness. I am currently trying to build a 2990wx system and stumbled on the same incoherence where the gskill qvl listed my board but the board qvl was not listing the ram.
I think now I'll try to respect the board qvl  instead of the memory one. We never know.

good luck finding whats slowing you down. keep the thread updated :) if you can

prolly not related but the memory you listed (f4-2933c14q2-128gtzrx) doesnt appear on the motherboard QVL http://download.gigabyte.eu/FileList/Memory/mb_memory_x399-aorus-xtreme_2nd.pdf

actually g.skill website says aorus xtreme motherboard is on QVL https://www.gskill.com/en/product/f4-2933c14q2-128gtzrx
Maybe list from gigabyte isn't up to date.

yah this is strange.
i found another qvl for this card where the memory f4-2933c14q2-128gtzrx appears.
http://download.gigabyte.cn/FileList/Memory/mb_memory_x399-aorus-xtreme.pdf


i don't know which pdf is the most recent tho. the one where your ram doesnt appear has the mention "2nd" at the end of its name.

edit: from this page http://download.gigabyte.cn/FileList/Memory/  it seems the one which doesnt contain your ram is the most recent
edit 2 : http://download.gigabyte.cn/FileList/Memory/mb_memory_x399-aorus-xtreme_2990WX.pdf   this seems to be the good pdf to look at (doesnt contain f4-2933c14q2-128gtzrx)
