How could I overvolting the NB (SIS 645DX chipset) on my Asus P4S533 motherboard. I would like to get higher FSB, because the CPU and RAMs could handle it. The NB stays cool under Zalman heatsink, so it definitely could run with higher voltage. Does anyone know voltage modification for it[:p]?

Asus P4S533 is the fastest motherboard for 3dfx AGP systems, so this question is very important. If some of you is familiar with electrician, I would even send you a motherboard to find out the way of overvolting!
