I'm having a nightmare time with 1605 and my 1090T - no matter what I try - it refuses to prime stable @ 4Ghz irrespective of vcore / settings

Prime95 Blend lasts a maximum of 3-4hours before either causing BSOD, Blank screen, or complete reboot!


Used to work 4Ghz perfectly fine (24 hr's prime blend stable) on all previous BIOS's with Turbo Off
