You should not raise the voltage until you begin having stability problems. For example, use default voltage and set the FSB at 110 MHz (16X110=1760 MHz). Next step should be test for stability and then check load CPU temps. If all is well, then step up to maybe 112 FSB and see if it's stable and if the temps are still ok. At some point along the way, you'll lose stability (BSOD, crash, or lockup). Next, raise the voltage up one step and repeat stability test and check for temps. It's a trial and error thing. Each system is different. Don't use anymore voltage than you need, because overvolting can damage the CPU by heat and electromigration.
