Bah! Go for 4ghz. I have a 1.312vid q6600, and was able to get prime95 stable at 4ghz, although on a high 1.65vcore. That low vid chip is wasted on you. Shame on you!
i had to save up like 3 monthes to get this pc. so u can imagin how scared i am to do any thing to it.
but in time. im gonna do it. ill go as high as possible. just waiting for the right time when i have enough money to burn this chip.
