Hi I just got a P5N D mainboard so i can run 2 graphics cards in SLI. But after i installed this motherboard, i can only get my Q6600 to 2.8 GHz. with my old P5K SE motherboard i could get my CPU up to 3.4 and it was stable. I have a Zalman 9700 cooler, and 500W PSU. Before i used the BIOS to overclock and all i had to do was change the FSB from 266 to 378 and it worked. Now with my new motherboard i can't figure out how to use the BIOS to overclock and i use the AI Suite utility that came with the motherboard. Does anyone know how to Use the BIOS to properly overclock my CPU, because i want to get it to at least 3.2 GHz Thanks!
