Will you go out the great result when "PCI-E(102)" and "CPU Clock Skew" and "IOH Clock Skew" are reviewed ???

　　
Damn nice voltages mate, are you using CPU/IOH clock skew, if so what values do you have them set to?

I have my CPU clock skew set to 100ps for my 4GHz o/c, it has helped me get both my Vcore and Vtt down quite a bit.

I am now stable with 1.2645v Vcore and 1.215v Vtt, whereas before I set clock skew to 100ps, I needed Vtt at 1.275v and 1.2875v Vcore, it has made quite a difference to my load temps having these voltages down as low as this, though I wish I could use low voltages like some of the guys on here.

No mate, that wasn't a typo, I'm running 1.300v CPU PLL, and my boards default is 1.800v, I read on EVGA forums that lowering this setting can actually help with stability, so I started playing around with it to get my 4.2GHz o/c stable, and I got it right down to 1.300v, when it was at 1.800v my overclock was unstable, now it is perfectly stable.

I know several other guys using 1.300v CPU PLL as well.

Have you tried lowering it down even further than 1.82v?
