Hi,

the first thing you should to is returning to the default CPU voltage if you don't get stable.

However a quadcore puts more stress on the northbridge and it is impossible to tell what your issue is unless we get more infos on your hardware and settings.

My Q9300 C1/M1 runs at 1.325V at 3.45 GHz on a P45 chipset (1.28V, ASUS P5Q3). Just as a rough guideline.
