When I enable XMP and stress the cpu the PC reboots.
The temps seem fine when testing them.
I ran several test and sometimes found it would be stable for a few hours so played some games and it would reboot, when stressing it after the reboot it would reboot again.
Stressing the gpu seems to cause no reboots and I am yet to get one with xmp disabled.
The RAM is on the QVL list and both are in slots 2 and 4.
I've also tried OC the ram myself with the correct timings and voltage etc still no luck.
