I built my first computer a while back and had quite a few difficulties. I used an asus p5wdh deluxe mb, with 3GB of ram and a C2D 6750 2.6GHz processor. In the begining the MB defaulted to the incorrect voltage for the ram, and after I figured that out, I still wound up having the slow the fsb speed from the defaulted 333 to 266 in order to make it stable. Now the machine is very stable, but I would like to increase that fsb speed. The max available with the mb is 5 hundred and something. This confuses me more because I think it should be higher. Does anyone have any ideas? I can post pics if need be. Thanks in advance for the help.
