I found out an interesting thing about the PS;
each of the main rails (3.3/5/12) has a sense wire. This wire is smaller gauge and connects to the voltage rail at the mobo connector. I did a little reading and this sense wire is supposed to monitor the voltage at the connector to provide feedback to the regulator. So, this PS individually regulates each rail; nice!
Well, I got to thinking and discovered that if you use a voltage divider, you can trick the sense wire into thinking it is seeing less voltage than there is and needs to boost that rail. The resistor values you need depend on the rail you are trying to boost. Use two resistors in series (so total is around 100-150 ohms; higher values don't work well). One end goes to the voltage rail, the other end other goes to ground, then hook the sense wire to where the resistors meet.
Most PS units use only one of the rails to regulate all three rails, so it'll take some playing around depending on the PS unit you're using.
I love playing with this stuff!
