this is tempting me to disable cores and overclock more... run a bench to compare your 6 core overclock and 4 core overclock?

It's different:
Disabling cores in the BIOS is something fisical. You do disable the cores, your hardware won't interact with it, neither your OS. They are still there, but no power is pulled by them. They are OFF.

As for disabling them in windows, that is a virtual action. The cores are still powered on, they still draw power. But your OS won't use them, your software won't be able to use those cores, but they will be there, powered on and alive.

So if you run prime, your temps decrease a little because you will have 4 cores under load an 2 on idle.
To check this out, try to enable all of your 6 cores and run prime on only 4 threads.
The temps should be the same, if you can stress only the 4 cores windows was stressing.

your right. the temps were the same. thanks for clearing that up. but theres no option in the msi nf750-g55 bios to disable any cores though. i looked through the manual and still got nothing. so the OP wont be able to disable those cores.
