Bah! It looks like I am having the same problems as Smit. Instead of the FSB barrier of 400, mine is limited at 375. I am currently using F5 -- but then again it keeps switching back and forth and .... well, I don't really know which bios version I am switching the settings at anymore.
I cranked every voltage up: Dram at 2.2v, cpu voltage at 1.5 and I can barely make it to my windows with a FSB of 370 and it'll still crash. Ram is currently underclocked to 742.
I disabled every setting in the BIOS, C1, etc, etc, and lowered the LDT frequency from 5x to 4x as suggested in the review by VR-Zone. (What does LDT do anyway?)
Still cant get anything past 370
I know the CPU could go higher as I have gotten it to post and into windows at 3.6Ghz on the ASUS 650i board.
Is there any hope left for me in this Gigabyte board?
Currently using a E6600 w/ arctic Freezer 7 pro. Crucial Ballistix PC2 8000.
btw -- Im jealous of cubeless......
P.S.
Gigabyte mispells voltage in the bios. Mispells Check in the online bios utility and much more! --Just funny.
