No problemo! PPGA celeron on Abit ZM-6 motherboard! You can lower the cpu core voltage to 2.0v or 2.1v you experience any unstability! Mine works fine:) Extra fan would do the trick too!!! by the way! The multiplier was 7x of course becouse it´s locked, but the external bus clock speed was raised to 83Mhz, but you can also try it with 75Mhz external bus speed!!!
