Hello,
I have AMD Phenom II X6 1090T @3.20GHz. 1 year ago my brother tried to change clock speed to 4.00GHz from 3.20GHz. And It succeed. I used it without any problems but now I changed my motherboard and I don't know anything about OC. I have Cooler Master's CPU Cooler so it's not a stock fan I think it'll handle 4GHz but I don't know how to do it. Could you please help me in this case?

Sorry for my English it's not my main language. Thanks. :)

Edit: Sorry, I forgot the mention my Mobo.
GIGABYTE 990XA :)
