Older CPUs are OCd only by altering the BUS. So, the first option in BIOS is to desable "Spread spectrum" so it wont affect the other components. RAM speed is going to be affectet alltough... so, you need to play with the ram ratio aswell (lower it). Then start increasing the bus, i say untill you get 3,2 GHz, run stress tests, monitor temps etc, then rais a bit more to 3,3 - 3,4. Dont alter the core voltage, i think you are fine with default.

Spread spectrum - disable it
Vcore = dont ouch it
PCI-e = dont touch it
RAM- if you have RAM that is able to OC well, then you need to check the frequency to. But first change your BUS, go to RAm and try to keep it @ arround the default speed (if you MB can keep you ram @ the default speed even wehn you change the BUS then you dont need to do that)
