System crashing on custom voltage settings

[krysta24]

Hello guys,

I recently bought new PSU to my old computer (c2q q6600, Asus p5kc, Seasonic ss-350et, Kingston UV400 240gb), so I wanted to overclock it a bit. I bumped FSB from 266 to 333 (2,4GHz to 3GHz) with no issues, but I wanted lower noise and I tried lowering voltage (it was set on auto) I tried 1,3V which I thought was really safe for a start but I got BSOD during windows boot. I tried a few other values about this but every time it crashed same way. I have no idea what´s wrong because the voltage, as well as the temperatures, seems OK to me (56°C in CPU-Z stress test), but obviously, it has some problems with the voltage I set because on auto it´s running just OK.

 

BTW. sorry for my English

There's no guarantee a cpu will be stable after voltage tampering, even by a small amount. Your chip may simply be very picky in this regard.
