Offset voltage Asus Mobo

Hi,

I would like to ask if anyone can point me to a great guide on how to set offset voltage on Asus motherboards (P8Z77-V LX). At the moment, I have i5-3570k @ 4200Mhz at 1.232 V. I believe I could achieve many benefits (power savings, processor lifecycle) if I use offset voltage for processor and none of the drawbacks.

I can't remember exact features which I am enabled/disabled in BIOS, but I have some load-line calibration, disabled turbo, still have the feature which downclocks CPU to 1600Mhz while idle.

Thank you for your help, I would really love to have same performance as I currently have with an ability to offset voltage to the stock while idle.

Same principles apply to all the asus boards. I use offset mode to oc on my system.
