I have a shuttle An35n Ultra 400 w/batron 2500+ it is currently overclocked to 2ghz. 200 x 10 @1.7v.
I dont know if this is normal, but in bios in the voltage settings where it lists the different voltages, the top one on the list says "auto" and that is what I have selected and everything is fine. In the auto setting my voltage is 1.7v. When I try to change the voltage to to anything other than auto my computer locks up when I save settings and restart.
whats the deal? It would be nice to change the voltage to 1.8 and see how much higher I can get the oc. Is there anyone out there with a AN35N having the same problem? What could be the porblem?
