I am not new to computer building but never really got into the OC'ing stuff. I built a PC that will be primarily used for gaming and ripping/encoding HD-DVD/Bluray and would like to do some tests and see if OC'ing makes any sense for me. I am using a gigabyte X48-ds4 board with a q9550 quad core cpu. I have played around a little bit in the bios but for some reason no matter what i set the multiplier and speed to it defaults to 2.83g, im not trying any crazy numbers here just really trying to get to 3.0 and see how it runs. What am i doing wrong?
