Tried installing a AMD 2600+ 333fsb on my KT3 Ultra2 Rev 1.0 mainboard but could not figure out how to get it to run as a 2600+. Checked the MSI processor support page and the 2600+ 333fsb isn't listed but the 2800+ 333fsb is listed. Flashed to the 5.7 bios but still no go. Is the 2600+ 333fsb not supported or is there some settings in bios I am missing.
