Im running the FX5200 and i was stumbled upon a problem within the drivers. Until recently i was running XP home, just a few days ago i installed XP pro, when i was running home i could clock my graphics card withing the Nvidia drivers, but now that i am running Pro the tab has dissapeared. anyone got any ideas on how i could fix this? or know of any other reliable programs that will allow me to overclock my graphics card?
