Do it manually. I have the P5k-e/WIFI, and I simply changed it to "manual", and then changed the fsb to 333. That takes the 2160 to 3 GHz (you'll also have to up the volts to the chip a bit - don't go over 1.5V). If you don't have good cooling, set the multiplier back to 8, that will give you 2.67 Ghz, which is still plenty fast.
