Can you explain how to do it?
*BEFORE ATTEMPTING TO UNLOCK AND OVERCLOCK, REPLACE THE STOCK HEATSINK FAN WITH A MORE EFFICIENT ONE LIKE A COOLERMASTER HYPER 212+/212 EVO OR A CORSAIR A50/A70. THEY CAN BE FOUND REALLY CHEAP ON THE NET. IF YOU DON'T WANT TO BUY A BETTER FAN, LEAVE THE CPU STOCK.*
It's in the BIOS...an option called ACC (Advanced Clock Calibration). You simply have to activate it in the BIOS, reboot and see if it's stable...you'll notice it quick.
If it is, congratulations on your X6 for the price of a X4!
If it isn't, simply re-enter BIOS and disable the option and reboot.
For overclocking someone will be able to better inform you how to do it properly. My CPU, PHenom II X4 955, which was stock at 3.2GHz, went up to 3.7GHz without touching the voltage and could do 4+GHz if I was not afraid of playing with the voltage
