Head over to the
AMD Overclocking Club, if you ask nicely I'm sure someone will be happy to help you.
The basics are pretty much the same as AMD chips have been for a while. If you're going for a mild overclock, start out 100MHz-200MHz increases at a time. When under stress the system crashes, then you know you need just a little more voltage. Only touch the multiplier and vCore until you get an idea of what you're doing, too many variables in the mix make for tough troubleshooting.
But rule #1 is make sure you have adequate cooling, the stock cooler simply wont cut it.
