Set your base clock to 143Mhz, leave turbo and HT on.
Set the Vcore to 1.3V
Set the memory voltage and timings to default, 8x multiplier
QPI voltage to 1.3V
Leave everything else for first and boot up.
If it posts and manages to get into windows, stability test.
If it doesn't work,
Set the Vcore to 1.33V
Try again, keep going to 1.36V
If at 1.36V, try setting the QPI voltage to 1.35V
Then if stable you can go higher base clocks until unstable, then focus mainly on the vcore and qpi volts.
Make sure that the QPI speed is below 7.5Ghz, usually more stable then. (3.75Ghz * 2)
And keep an eye on when the memory reaches the 1333Mhz, as after that it may need a bit more volts if it is overclocked or it may be fine depending on how lucky you are.
First of all 4 hours is probably needed for overclocking, then once at desired clock speed 8+ hours is preferred.
