What he said

Be aware that increasing the CPU-NB will increase the heat on your chip.

I am so confused.

NB - North Bridge

CPU-NB - IMC (Integrated Memory Controller)


EDIT: NB voltage is not 1.2v max. All the 790X, FX and 890 chipsets can run 1.4v recommend for 24/7

CPU-NB/IMC is 1.55v MAX, as the same for the CPU
