I assume you have LLC enabled? What ambients? You could try turning off Speedstep, its probably worth 0.01-0.03V

Otherwise those temps seem pretty normal with that high a voltage and with your cooler.

LLC is on Auto. Will disabling or enabling it result in 4Ghz at lower voltage??

Iam seeing a 24 point increase in 3DMark11 from 3.8 to 4ghz.

Disabling it will mean your Vcore will drop under load so you will set it higher in the bios. Some people like it, some people don't, sometimes it makes a difference in your temps and stability, you should try both and see which one does better for you.

Not really with those temps imo : /

I thought the CPU PLL was meant to be left alone or undervolted though, not overvolted?


Have you tried dropping it instead of increasing it?
