The Threadripper with 128 GB RAM (!) BUILDERS thread

I pushed up vDIMM (AB and CD) to 1.5v, and vSoC to 1.35v, but still the same Prime95 errors @ 3200 Mhz. Trying at lower speeds now.

Update: lowered vSoC to 1.2v (but kept vDIMM at 1.5v) after reading warnings not to push that too high. Prime95 appears to have no errors @ 2900 Mhz. A far cry so far from 3466 that others have achieved, but certainly better than the 2400 I achieved with the old Hynix RAM. Perhaps more tinkering will get me higher.

BTW I'm doing this in the BIOS but should I be doing in Ryzen Master instead?

I'm using 16GB Samsung B-Die RAM as well and the max I could do regardless of sane adjustments was ~2900. I could break 3000, but it took 1.35 vSOC and 1.45V on RAM. Not work it to me for a couple hundred Mhz.
 
I would not spend your time with Ryzen Master. You can try it - I had to use it in the early x370 days to get DDR4-3200 - but by now UEFIs should be mature enough that you wouldn't need it.

Is the CPU overclocked while you are attempting this? Sometimes you have to raise vcore to get anywhere with your RAM.
 
I arrived late to the party to say that I found that system76 offers threadripper builds with 1287GB memor5y clocked @2933Mhz. Any idea motherboard/memory they are using?

Also, that is an ECC memory...

Nice find and about motherboard? is it a custom one?
or even better witch of the existing motherboards will get that RAM speed up to 2933MHz,
or to go the extra mile, since its been a year since the 2950X release, are there any recommended combinations for a 128GB/high speed motherboard/RAM?

I believe any X399 motherboard will work, but L1Tech tested it on two brands - AsRock and Gigabyte.Memory speed will be more dependant on your CPU lottery than on motherboard itself. Currently all X399 boards have fairly mature BIOS and at least in my case, hitting 3333MHz was not a problem on 4x8GB G.Skill Samsung B-Die kit (I know that more moduls lowers max. clock, just saying how my system is setup).

That is not ECC memory, just gskill samsung b-die. Anybody else care to back me up on that ?
