Hello i have a 3400+ (clawhammer core) @ 2.20Ghz on a asus K8V Deluxe. There are overclocking options in the bios however whenever I raise the core or voltage etc etc it says overclocking failed please continue to setup. I have very decent temps for stock cooling 30/32C idle, 38/45C gaming. A better fan/HS is no problem to aquire but I know thats not the problem. I do not know alot about overclocking so some help would be appreciated.
