So I recently got an i7-8700k and an ASRock Z390 phantom gaming 6 motherboard for my computer it’s been about two weeks and I have had zero problems till last night when I was playing destiny my pc randomly blue screened. I turned my OC on my cpu back 4.5 (it was originally at 4.7) and my pc still blue screened i then just disabled Xmp on the ram and put the cpu back to stock and then played for the rest of the night with 0 issues. When I overclock I tend not to play with voltages, I’d like to oc my cpu back to somewhere between 4.5 and 4.7 does anyone know a good voltage for that or would I be better of trying the motherboards auto overclock mode? and also could it have been a ram xmp issue?
