Raising the vcore

Well i just tried to increase my FSB from 100 to 133. My system just wont boot, the screen remains black. As i got PC 133 Ram and the Asus P3B-F, components should not be the problem here.
So it must be the core voltage which has to be increased. The problem is, that i got my Tualatin Celeron running on an adapter card.

The question is : Do i have to increase the voltage on the card via jumper or in the bios ? Current bios setting is 1,65

bios set it to around 1.725

hmm i even tried 1,75 in Bios, but still the black screen

maybe i should try more

up the vdimm voltage a bit maybe that wud give u stability.
