MCE: Micro-op cache data parity error Ryzen 5 3600

Issue Description:

Ever since December last year I got any application crashing after about 10 seconds. Searching for the error I had replaced and tested so far the GPU, RAM, PSU, drives and MB. Last week I installed the new MB and tired to install Windows resulting in errors during the middle half of the process. After trying for about 5 installs I swapped to a Linux distro and it froze. Soon enough I got a distro straight into RAM and checked dmesg. In there I found several segfaults and 2 MCE errors. From my experience the MCE errors come in 1 about every 3-4 mins.

 

MCE error
