Why is my CPU clocking down under full load?

post #1 of 4
Thread Starter 
I can prime95 @ 4.4GHz, at a wavering 1.232-1.240v perfectly fine.

4.5GHz at that voltage BSODs, so I bumped the voltage via Offset mode to 1.290v. (was going to continue to increase the multiplier, but i ran into this issue)

It primes @ 4.5GHz perfectly fine, but after a minute or two, cpu-z will begin to report the GHz and voltage dropping, and i mean drop, the ghz i've seen go as low as 3GHz and the voltage as low as 1.095 before turning off prime. it'll slowly go down like 4.3, 4.1, 4, 3.8, etc etc

Why is it doing this? I'm not overheating at all.

I'm a beginner at OCing Intel, any help is appreciated

Not to be a nuisance but can you explain WHY i have to change those settings?

Just trying to get a feel for when and why they would have to be changed in the first place.

Those allow the CPU to draw more than the usual TDP of 95w under load, iirc.
