Hey, I own a GA-P31-DS3L and a E8400. Having looked over the net they both seem to have good OC performance, especially the CPU. So I set out to bump it to 4GHz on air with the AC7 Alpine cooler. The problem is for some reason the FSB setting won't get properly saved or used. When I change it save and exit, the pc starts with the default fsb. The strange thing is that overvoltages and multipliers are saved just fine, everything except changing the FSB is working. I tried overvolting the FSB, the CPU, the ram, even used some looser timings but it would still revert to the default 333MHz after the "Save and Exit". Also when I do that the screen goes black like a failed shutdown and i have to reset or turn it off manually. I've tried reseting the cmos, the battery is fresh, i got the latest bios. A friend even suggested upping the PCIe bus because as he said it the PCIe clock may be linked to the fsb. Here are some pics.
