Good morning,

I'm a new user - my name is Mawrecki. It's a pleasure to be here.

I'm a Scientists who is using Machine/Deep Learning daily.
I got a new PC for my job which includes all the components below.
I'd like to set it in such a way that it works with the highest efficiency and stability.

The thing is, that after XMP 2.0 activation in the BIOS, I heard three beeps.
Which mean I cannot use 3600 MHz frequency of my memory and I had to turn XMP off.

My set:
  • Gigabyte X399 AORUS PRO
  • AMD Ryzen Threadripper 1950x
  • NZXT Kraken X62
  • G.SKILL 32GB (2x16GB) 3600MHz CL16 TridentZ - 2x
  • 970 EVO Plus 1TB
  • Chieftec GPS-1250C 1250W
  • MasterBox MB600L

What I checked by myself:
  • BIOS was upgraded from F1 (01/10/2018) to F2 (16/12/2019);
  • I checked Qualified Vendors List (QVL) X399 AORUS PRO and I see that G.SKILL and 3600 MHz frequency should be supported;
  • I checked X399 AORUS PRO User's Manual to support Quad Channel memory configuration properly;
  • I was able to changed DRAM voltage by hand from 1.200V to 1.350V and multiplier to 30 what allows me to set 3000 MHz without beeps and errors;

After 14h of MemTest86 testing I got result:

The question is, what should I do to be able to use XMP 2.0 and 3600 MHz by default without any issues.

Thank you for all of your answers and comments.

Threadripper 1000 is not designed to run at 3600. In most cases, it won't run stable above ~3200 using 16GB memory modules. If you had 4 memory slot motherboard then you could push it to ~3466-3600, depends on IMC quality and luck but on 8 slot motherboards it simply won't run like that (or you need much more luck). I recommend to set something like 3200 15-17-17 Command Rate 1N and play with a lower tRFC, maybe around 400.
3600 is generally supported but using 8GB modules which are easier to OC. Also, everything past 2666 on this motherboard is counted as overclocking so not guaranteed. You can play with a higher SOC voltage (up to 1.2V), VDIMM up to ~1.45V or manual settings for some sub-timings. However, I think you care about full stability and overclocking may take a lot of time till you find these perfect settings.

If it's not too late and you bought those mem modules new. I would see if they could be exchanged for FlareX 3200 CL14 these would most likely run at the rated 3200 MHz using XMP
