Okay, sounds stupid but I am curious. Tomorrow my motherboard arrives....ASUS G4A89GTD PRO...it will be a few more days until my 1055 AMD phenom II x6 arrives.. I check the QVL @ the ASUS site for compatable processors and it doesn't list my previous AMD phenom x4 and I was wondering what the worst possible thing that could happen would be. I only ask because I read some people have used different RAM sticks than specified and havent experienced any ill effects. Would it just not recognize the phenom X4? Or could it possibly fry either/or/both? I know It would physically fit but I understand that means nothing. I dropped $100 for the board and don't want a bbq. Thanks!
