Nope there shouldn't be anything you need to change in Your BIOS.
However you must remember that you dont want the temps for that CPU to go above 62C (143.6F) and that the max voltage is 1.4V
Be very careful as going above one of these two limits CAN FRY YOUR CPU!!
take your time and make minor adjustments slowly. First you will need a stress/stability tester Prime95
make sure you have CPU-Z
that will give you your Mhz and Voltage.
you will also need HWmonitor
so the you make sure you are not overheating
After you make an adjustment in Overdrive start to run Prime95 while watching your temps with HWmonitor, making sure that they are safe.
after running Prime 95 for a while and A
. your computer does not crash and B
. Your temps remain at a safe level.
you may increase the overclock slightly. repeat these steps until your computer crashes, or your temps get dangerous.
once one of these two things happen, back-off the overclock a bit and run prime 95 once more, if everything is fine that should be a correct overclock.
Remember that overclocking reduces the life-span of a CPU. so you might not want to keep this overclock on all the time. maybe just when playing games and other heavy loads
EDIT: just out of curiosity why did you want to OC your CPU?
