Hi. I have a MSI K7T266 Pro2RU with Athlon XP 1600+ and i cannot push the FSB more than 140 mhz with default voltage selected, so i tried to give some more voltage for stability, tried 1.775 - 1.800 but when i check it with MBM 5 inside XP pro ti goes from 1.680 to 1.748, it never goes to the settings i put in bios. Is there a problem or not? Using Enermax 350W psu with 2 Quantum Fireball HDDs, Pioneer DVD, HP CDRW and Geforce2GTS.
