Hi, I recently upgraded my CPU+motherboard to a Ryzen 5 5600X and a Gigabyte B550M AORUS PRO over the weekend. Since then my computer has been shutting off/crashing (power straight up cut, not BSoD, can turn PC back on immediately after) during high sustained CPU loads. (high fps games, cinebench, etc)
I have been troubleshooting since then and in the process, I have ruled out a couple of potential issues. I initially suspected it was overheating, so I bought a new CPU cooler and now my temperatures under max load is 75 degrees Celsius. Then I did a fresh reinstall of Windows. Finally, I tried updating my BIOS to F11g and still no dice.
Eventually, I found out that turning off core performance boost in the BIOS has allowed my system to be stable at high sustained CPU loads. However, this disables the turbo frequency and therefore the all cores are permanently stuck at 3.7 GHz or below, never to go higher.
I am unsure what to do now and help regarding this issue would be greatly appreciated.
System specs:
OS: Windows 10 version 20H2
CPU: Ryzen 5 5600X
CPU cooler: Dark Rock 4
Motherboard: GIGABYTE B550M AORUS PRO
RAM: Crucial Ballistix 2x8 3200MHz CL16
GPU: GIGABYTE RTX 2070 SUPER WINDFORCE OC 3X
PSU: Corsair CX-M 650w (had this in my previous build and was working fine, don't think it's the PSU)
BIOS version: F11g
