Its from Hardforum - thread by ASUS staff.

4.7GHz and above
CPU Turbo Multiplier – To desired value
Dram Voltage to specification
Digi + VRM options
VRM Frequency change to 350 – this value will allow for scaling to 50+ multi without issues
Phase Control change to extreme – this value will allow for scaling to 50+ multi without issues
Duty Control change to extreme - this value will for scaling to 50+ multi without issues.
No other values need to be changed. Unless otherwise noted all other UEFI values used are AUTO.

Enter a value of 350. This is best for sustaining stability at multis of 48x or above. This is key especially for running unrealistic loading testing such as prime or linx.

Yes. I understand that this is the 'safest' way, however based on the fact the chip can achieve 4.6GHz @ 1.385v, it can be logically estimated that an increase to 5Ghz would require a vcore somewhere between 1.42-1.48, obviously each chip is different, thus the range. Just trying to save OP some time

"Each chip is different" could not be more true... My chip can do 4.6Ghz @ 1.375v no problem, but 5 GHz needs well over 1.5v to stable. Most of these chips can't do 5 GHz with any measure of stability, and the ones that can often need close to 1.5v.

Check out the SB 5 Ghz Club and you'll see that a large number of these chips need 1.48 or more, with many being over 1.5v... so I have to say that I agree with the idea of starting with 1.52v and stepping down. Some chips still require even more juice than this.

If you can get it up to 4.8 GHz fully stable, then pat yourself on the back. It really is a great overclock. I know that many of us feel that 5 GHz is the magic number, but sometimes we need to be realistic too It's just a fact that not every chip can achieve this with stability.

Okay thanks so much for the great information. I am on my way home from work now and determined to see if I can get this stable at 4.8+ at a "reasonable" voltage.
