Is your chip not a Phenom 11 x 6 1090T? But whatever overclocking you have in mind you will certainly need a better cooler than the stock one. The Arctic Cooling Freezer A30 is certainly a decent cooler I have a Artic cooler in one of my PC's.
I have managed to find a video which may help but I cannot provide detailed help as I am an Intel man and my current CPU the i5 2500K is simplicity to overclock to 4.5Ghz from 3.3Ghz.
To thoroughly test your overclock Prime95 is a popular torture-testing program or Intel Burn Test, OCCT, Cinebench, 3dmark.
