All Celerons have locked multipliers and there is no way to unlock 'em, sorry.

On the bright side, 5.5 is a very good multiiplier for most celerons of that era. C366@550MHz (100fsb) was one of those magic combinations, and likely most of us old hands have had one (or more) ourselves. I've still got one around here somewhere, and it's still a nice setup.

yup my cele does 550 at stock voltage and it ran 3ds max 5

only when i tryed to put it up to 133 it booted then went black i don't think it liked that too much.
