In overclocking what roll does the voltage play (2.2,thru 2.9) in the performance of a P233 chip. What are the best setting to use. I have tried to overclock it and it reboots when the monitor refreshes. The settings I used are 3.5x, 75mhz and 83mhz. The voltage setting was 2.9, could this be the problem?(Recommended by intel (2.9v))
