Overclocking an i7 960

[Cuzzin Chizzy]

If I want to overclock to 4.2GHz what types of voltages should I be looking at for a good safe/stable overclock?

my rig is

ASUS Rampage iii Formula Motherboard
Intel i7 960 @ 3.2 GHz stock
Corsair H70 cooler
12GB of Corsair Dominator RAM
EVGA GTX 570 HD 2.5GB



would something like this be okay?
CPU Voltage 1.4375
CPU PLL 1.812 on auto

That CPU voltage is too high! The manufacturer (Intel) rates the max voltage at 1.375 V

I am running my i920 at 4010MHz with 1.264v. So I would expect you to be able to reach around this with lower than 1.4375. At that voltage you will have very large heat issues and damage the cpu.

is QPI/DRAM 1.375 okay?
Tried a lower CPU voltage and got BSOD . Not sure what I need to do next.
