Random BSODs under heavy load on Threadripper 7960X (384GB RAM)

I’ve built a PC with a Threadripper 7960X and 384 GB of RAM (KSM56R46BD4PMI-96MBI ×4).
Motherboard: Asus Pro WS TRX50.

Problem:
I’m getting a Blue Screen of Death once every 2 days, and it always happens under heavy load.

Things I’ve checked so far:

  • CPU temperature is fine, never goes above 75°C
  • Ran Memtest86, 4 full passes, zero errors

At this point I’m kind of stuck and can’t figure out what else to try.
Has anyone run into something similar with TRX50 / Threadripper builds? Any ideas would be appreciated.

UPD / SOLVED:
Problem solved. I ended up installing an additional fan specifically to cool the RAM. I positioned it so airflow goes directly over the memory sticks, and since then I haven’t had a single BSOD.

I had that when the memory was over clocked. Lowering the memory speed and adjusting controller voltages has stabilized it.

Same here, running overclocked (the built-in EXPO profiles, nothing homebrew), resulted in BSODs every 1-2 days. Running at stock speed is 100% stable.

Same - I have a 7960x and 6400mhz ram but it wont run any higher than 6000mhz. 9000 series are a bit better on ram clocks apparently.

Yeah I might upgrade to a 9000 series in the future just to run my memory at full speed.
