Problems with F4-3600C16Q-32GTZKK and Ryzen 9 3900X

[shmerl]

I just finished a new build:

MB: Asrock X570 Taichi (firmware 2.0)
CPU: Ryzen 9 3900X
RAM: 32 GB Trident Z L16-16-16-36 1.35V (F4-3600C16Q-32GTZKK): http://www.gskill.com/specification/...-Specification

I used Ryzen DRAM calculator to set voltages and timings for 3600 MHz (safe preset).

I noticed, it reboots when under heavy load, like compiling Linux kernel with 24 threads. I run stressapptest like this

stressapptest -W -M 30474 -s 900 -m 24 --pause_delay 300

and I see these errors:

Log: CrcWarmCopyPage CRC mismatch 5e9f7fffa25eaaaaaa4c230aca2a88172311aaaa8799 != ffffffff01ffffffff011002aaaa9ac801002aaaa9ac80, but no miscompares found. Retrying with fresh data.

Does it mean there is some problem with RAM?

Hm, I actually managed to make that test pass, by bumping RAM voltage a bit to 1.356 V.
