Re: Overclcoking question
Well first off you're not at 980 FSB, you're at 245. Current processors are quad pumped, which effectively quadruples the FSB. DDR RAM is double pumped, which doubles the FSB for them, hence Double Data Rate.
Now it could be any number of things holding you back. VCore is a good guess, put it up step by step in the BIOS to see if it helps, watching temps closely.
