I tried two different BIOS setups last night.
i7 3820, Rampage 4 Gene, BIOS 1305, 125x39 1.504 Vcore loaded, Prime95 with AVX Win7 SP1
Turbo Mode: All Core 125x39
Turbo Mode: Per Core 125x39 (39 set for all entries in the per core section to force 39)
With All core mode temps under load were
With Per Core mode set and no other changes temps were
Running the exact same setups for all other settings, exact same software environment, and exact same thermal loading. Testing done within 5 minutes of each other in the same location with same ambient temps.
Clearly there is some witchery going on with this and now I am not sure which setting's temperatures to trust, can anyone else duplicate this?
