All in all. I've been trying to solve problems with stutters on my build for a very long time.
Which I just haven't tried. And I seem to have found a solution that works for me:
1. Rolled back BIOS version on ASUS B450M-K to 3802 2. Disabled the item in the BIOS Erase fTPM for factory reset, but did not disable fTPM itself + deleted AMD psp 11 in the Device Manager in the Security Devices section. 3. Set the frequency to HyperX Fury from 3200 to 3600 directly in the BIOS without changing the timings.
