I've hit a brick wall

I cannot get my Celeron 2.6 above 2.91GHz (112MHz FSB).

Im using a Abit IS7 motherboard with the latest BIOS. Tried 1:1 memory speed but that did no good. Increased the CPU voltage to 1.575 (1.525 by default) and DDR voltage to 2.7v without any success. If I set the FSB to 113Mhz or more, PCmark and sandra will generate bug reports.

One thing that is very wierd is that voltage seems way too low in winbond hardware doctor. When on load at 112MHz, +3.3v goes down to about 3.04 and the program beeps lika an ambulance. The CPU voltage goes down too (to about 1.46v).

edit: Could it be my PSU`? It's a codegen 300W...

Raise your vcore up a few ticks & set the last 2 settings in your GAT to disabled.

I've ordered a Chieftec 360w PSU with dual fans instead. It weights more than twice as much as the codegen, and the components inside the codegen look like donald duck equipment in comparison
