When i overclock my pentium d 940 to 3.6 ghz it becomes so unstable that it usually freezes when it is loading the desktop. So i raised the voltage from 1.4 to 1.5V. This worked better. I could play songs and stuff, but it would freeze when i loaded up cs 1.6. So right now i have it at 3.5 Ghz. Should i increase the voltage anymore? Or would that make it unsafe?
