So it booted into windows and is priming at 45x, showing max Vcore of 1.4 at that speed and max Temp of 82C, but not sustained, since speed drops back to 34x/1.256v more often than not. Utilization still pegged at 100, and prime isn't throwing errors. How can I tell if the issue is with prime or the OC? Should I try bumping the turbo voltage and setting offset to Auto, or else setting turbo voltage to auto?
Perhaps my TIM needs a refresh.
Laser shows VRM sinks at 120F.
They are already maxxed, which for this board is 500.Sounds like the motherboard is throttling the CPU. Try increasing the power limits in Bios.
I agree. Looks like a crap chip, but it needs that much to complete boot to desktop, let alone start prime.4.5 and 1.4v is A LOT for that clockspeed... something is right there.
Have you tried blowing some air on the .osfets heatsinks?
