Could you guide me in doing so?
Sure, Cabbs has pretty much said everything but I suppose I can add some stuff:
- Running at 3.75GHz(that's what you're is at, right?), you shouldn't really need to change anything other than the Vcore. FSB (also known as VVT) and CPU PL should be at their defaults (1.1V for FSB and 1.2V-1.5V for PL) I'm not sure if Nvidia mobos have the latter option, though.
- Start with a relatively low Vcore, 1.25V for example, if it's not stable at 3.75GHz, just keep bumping it up until it is. Keep your RAM at 1:1 and you won't need to increase the voltage for that.
- If increasing the Vcore doesn't help stability, NB voltage is the most likely problem. Just bump it up one notch above default (default is usually the lowest value)
