For some reason I can't run my system at 133 fsb.. everything works fine at 100 mhz fsb.. but my 1800+ is runnin at 1150 mhz. When i set the fsb to 133 in the bios, fans still run and everything, just no video or any beeps. I had the exact same system runnin at 133 fsb before, just swapped out boards. Anybody have this same problem? Any input would be appreciated.
