Hello everyone,
I have a problem with my Threadripper 1950X and Memory speeds. My Corsair CMD128GX4M8A2666C15 8x16GB kit REFUSES to run on 2666 CL15 at the stated 1.2V, no matter what I do. I can get it partially stable, so that I get a BSOD once a week or twice a week which is not great since I want a stable and fast system. Normally I wouldn't bother with fast RAM but the Ryzen architecture strongly benefits from higher RAM speeds.
Motherboard is ASUS ROG ZENITH EXTREME with the BIOS version 1003 from before the AGESA upgrade for the Threadripper 2 as I do not plan to get one. Maybe shall I upgrade my BIOS to the most recent version?
The Threadripper is currently not overclocked (how should I even get started if the RAM doesn't overclock properly?!), except for the SoC pushed to 1V since I've read that it can make memory more stable. The Threadripper is cooled by a Corsair Hydro Series H115i with two 1400 maxRPM Noctua fans.
Other hardware:
400 GB Intel 750 Series NVMe PCIe Card SSD (OS)
1000 GB Intel 6000p Series M.2 NVMe SSD (Games + Documents folders)
GeForce Titan X 2nd Gen Maxwell.
Also, the BIOS is ignoring stuff I enter!!
I entered CL15 and it shows it running as CL16. I don't get it.
Secondly I set Command Rate to 2T, but it still runs on 1T?!
I tried to bring the DIMM voltages up to 1.4V for both banks and it made it POST with all modules at 2666 CL15, but this way I got minor stability issues in the form of a BSOD every 3-5 days (with SoC voltage on 1.1V). :/
In addition: When the System was new and also young, this kit wouldn't even POST with 128GB. Maximum was 64 so 4 sticks, after some new BIOS versions, it finally posted at 2133 CL15...
Do I do something wrong or is it just all for vain cause this RAM just doesn't run properly with this setup? :C
I was stupid anyway, I should have gone for 64 GB instead and should have get even faster RAM which is certified to work with this setup.
Allegedly the memory kit I mentioned above is in the QVL of this motherboard, though... But I doubt it or Corsair did changes to the kit that makes it difficult to run it within the XMP parameters.
Is there any chance to get this to work at 2666 CL15 reliably?
Nobody can help here? :C
Many thanks!
