if anybody else has an msi 266a pro2 then do they have the problem where you cannot run your pc with the fsb at 133. I have a 1800+ xp chip and it has to run at 1150mhz. I have tried changing the vcore voltage to 1.800 and the ram voltage to 2.7. When i do this the pc will get to where it loads the login screen on xp and it freezes on a black screen. I only have a 300W psu so this could be the problem. But having no money i want to make sure there is no other way to solve the problem before buying a better one. Thanks to anybody who can help.
