How high should I adjust my rails?

[Çhrist0ph]

Last week I bought my first PSU w/adjustable rails(OCZ 420w). My 12v is rocksolid@ 12.25 under idle and load. I have a 6800GT@ULTRA clocks and an Athlon XP@2.2ghz with 1gb of ddr ram, plus a couple drives and fans,etc. Should I raise my voltages and how high should I go? I am hoping more juice might help my oc.

ive heard of people running 3.9v+ 5.4v and 13v :|

i've got:

3.6 / 5.4 / 12.5
The 3.6 are set for burn-in my rams... They had only 2.8V - these nice BH-5 sticks...

Keep in mind:
CPU = 12V
Radeon GFX Cards = 5V
Ram, Northbridge-Southbridge = 3.3V

I would be aware that as more voltage equals more speed, it also starts to approach a max tolerance for each component.

You dont wanna blow a vid card, or other components, just because you want the rails to be high.

You can obviously limit the voltages on many components via the bios (cpu, ram, etc), but you cant limit the voltage going to other devices (hard drives, vide cards, etc). Keep those things in mind when you start to push the voltage up on components that are drawing current from each power rail of the psu.
