Re: new motherboard
That motherboard should be fine for OCing. Did you try updating the BIOS or raising the FSB? Also, the ram is no longer connected over the chipset but directly to the cpu that has a built in ram controller. The ram speed will rise at the same percentage as the FSB. For example raising the FSB by 10% will also raise the set ram clock by 10%.
