I am having a real problem. I just purchased a Q9550 Processor, but on my Gigabyte board with F13 BIOS, I cannot get the processor to overclock at all. It works fine at its stock speed, but if I raise the FSB by 5 points, the machine just reboots and loads the original BIOS settings. This is very frustrating. I had no problems overclocking the E6600 Duo Core, but cannot get it to budge with the Q9550. Does anybody know why I am having this problem? Is it a limitation with the Gigabyte Board? It has been a good motherboard for me. If it is the board, can someone recommend a motherboard that would work well with the Quad? Thank you very much!
