For some reason, I am unable to get my computer to post after changing the FSB on my A7A266 to 133MHz...both the motherboard and my memory are capable of running @ 133MHz (DDR 2100), but the processor doesn't seem to like it at all! I am running the latest bios revision for my board (1004.002), and am wondering if anyone has a similar set-up that could help me figure this out...the highest I can clock the FSB is 120MHz and get the computer to post, but it still won't boot into Windows.
