I've upgraded my cpu from an 1800xp to a 2600xp on the k7t266 pro2-a\nmotherboard and it only shows a 2000xp at start up. The fsb of the cpu\nis 266mz wich matches the motherboard. The multiplier ratio for the\ncpu is 16 but the bios only goes to 12.5 on auto setting with 15 as\nthe highest available. I tried to use 14 and 15 ratios but it kicks\nthe cpu down to lower settings. MSI cpu support states that this\nmotherboard supports the Athlon 26ooxp at 266mz fsb. Has anyone been\nable to work around this?
