I have a GA-945P S3, and I'm working on overclocking it. Trouble is, my cache drive is an SATA raid array that runs off of a PCI-E card. Whenever I overclock above about 10%, the card stops working properly in Windows, and the drive disappears. If I clock even higher, the system just doesn't post. (I'm not sure if this is hw limitation or the same PCI-E problem)
I think this problem is from the PCI-E bus being set as a fraction of the system bus. Apparently SATA cards have a hard time running at anything above 110mhz. Whatever, the BIOS has a setting to let me control the PCI-E frequency by hand, right? Apparently not. Setting it manually to 100 makes no difference. The system just doesn't post.
Any suggestions? Right now I can overclock and be sans-SATA RAID at about 2.8ghz, but the temp seems fine and I think I can do better. More to the point, I want to be able to use my SATA RAID and overclock at the same time, even if 2.8 is the limit!
Suggestions?
