Hi Everyone !

I have this extremely annoying «Code 68 Check CPU» message from time to time especially when doing 3D simulations.
Everything worked perfectly from months now but suddenly since a few weeks this appears. The computer crash during a simulation at random time and refuse to boot after that with this Code 68 message.
If I wait for a few minutes/hours, it boot properly and I can get back to work.

I have tried to take in and out the CPU, change the Thermalpaste, switch betweens GPU. I also have updated to the last Bios version and put everything on «optimized default».

CPU: AMD threadripper 2990Wx
MB: Asus zenith extreme,
PSU: 1600 G2, 80 PLUS Gold 1600W
Cooling system: Liqtech TR4 II 360, 360mm Radiator, 500W+ TDP, Liquid Cooling System
RAM: Ripjaws V Series 128GB (8 x 16GB)


I have zero idea from where this could come from. Can anyone help me on that please ?
