@elcompul As your colleague mentioned, you could if your motherboard allowed it. The problem is that your motherboard is not a wall, but I've looked on YouTube and in some videos they do OC on some micro with that motherboard, so in principle you could. I also tell you that it might be more worth it for you to look for a 775 Quad Core. On YouTube there are people with that motherboard and Quad Cores and today you can have a great PC without spending much. You won't be able to play current games, (some), but you can play games from years ago.
