Hello fellow overclockers!
I’ve got a rather lengthy and unfortunate tale about my Threadripper 1950X and its RAM issues.
In short:
It was November 2017 when my old rig failed due to exhausted PCIe lanes on the motherboard or CPU. I then discovered AMD’s Threadripper and was completely caught off guard—so I ordered the largest and most attractive RAM package I could find, without fully understanding how sensitive Ryzen RAM actually is: Corsair CMD128GX4M8A2666C15.
The first module failed, so I sent it back via RMA. Only after removing some parts did my system finally boot up with the new RAM. The fix came from a BIOS update.
Even now, without overclocking, my setup remains unstable at stock speed 2133 CL15. On the QVL, the kit is listed but with a specific version number I don’t have. Through RMA, I received an arbitrary version instead. That’s a real setback—I lost around 1400 EUR, mostly my fault.
I even swapped out the PSU because I thought voltage stability might be an issue.

Now my question is clear:
Which RAM is absolutely compatible with my current build?
My needs are:
- 64 GB as four modules (I doubt we can get eight stable ones)
- Highest possible XMP profile, ideally under 3200 MHz
- Minimal latencies

Full system specs:
Corsair HX1200i PSU
ASUS ROG ZENITH EXTREME
AMD Ryzen Threadripper 1950X – currently stable at 4GHz 1.375V
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
Dell UltraSharp UP3216Q

I really hope you can assist me in choosing the right RAM so I can enjoy a fast and stable setup for years to come, avoiding all the hassle and wasted money.
PS: I have the Enermax TR4 360mm liquid cooler. The pump always runs at full capacity, and my fan controller—my own DIY solution—works perfectly! Idle temps between 19-21°C, max 66°C during Prime95 stress tests.

*In case anyone wants to know more about the fan controller, I can share links via PM.*
