As with @cliffordcooley 's response you just need to have a little more than a stock cooler to be able to handle an overclock. Normally 3ghz on a Core 2 Quad is achievable with just a little bit of effort while keeping temps down.I have a ECS G31T-M7, Intel Core 2 Quad Q8300 2.50GHz, DDR2 2GB ram and GeForce GT 630 1GB.
I just going to ask if my computer can handle the OC? And if it can? Can it reach 3.0 GHz? Just asking
