The bios setting is like this :
PCIE FREQUENCY 100
Processor Multiplier set to 11.0 (max can go to 25x)
processor voltage set to 1.3v. (max can go to 1.35v, min is 0.8v).....minimum set to 1.4v
DDR voltage set to 2.70v. (max is 3.2v, min is 2.65v)
PCIE voltage set to 1.2v (max is 1.5v, min is 1.2v)
Vcore over-voltage (disable).......better enable, but have risk, normal vcore below 1.6v is still safe
