Scooter's Learning how to voltmod guide.
Heres a list of the voltage modifications that can be to the NF7-S:
Vdimm Mods:

Increasing the vdimm can shorten the life span of the memory, also heatspreaders are recommended. A small fan blowing over them can help aswell.
Vbt/Vtt Mods(Very useful in gaining stability when using a higher voltage on vdimm):
http://s6.invisionfree.com/underclock/index.php?showtopic=100
These mods are used to make the memory more stable. This is refered to as the secondary voltage to the vdimm. This setting should be exactly 1/2 of the vdimm. IE. vdimm=3.3 vtt=1.65 , is what you want.
Vdd Mods:

If you do any Vdd mods, meaning increasing voltage to the northbridge it is imperative that you have a better cooler on it. Some NF7-S' dont like high vdd voltage. My previous board wouldnt even boot with a 1.7vdd set in bios. So I did not even bother with it. Yours may differ tho.
Cooling:
Cooling several of the mosfets on the Abit NF7-S is a good idea aswell. Sinking the mosfets shown here, can help in stability and keep them from burning out. IF DOING THE VTT MOD PUT A HEATSINK ON THE CHIP LOCATED BELOW AS IT WLL GET VERY HOT.
Voltage Checkpoints:
WHEN DOING ANY KIND OF VOLTAGE CHECKING DO NOT USE A ANALOG VOLT/MULTI METER, THEY CAN KILL YOUR BOARD. USE ONLY A DIGITAL VOLT/MULTI METER.
It has to do with the analog meters resistance being so low that it shorts out the circuit its testing, which is what happened to me. The digital meters have a much higher resistance not totally shorting out the circuit.
