Dude, I'm an OCer from way back.
Remember the days of the Celeron 300-A? 450's in disguise!
Or searching for that PII-300 that was made in the Malaysia factory that was really a 450 in disguise? I had one of them running that's been running at 450MHz from 1998 till 2 weaks ago when it was finally replaced by my Athlon 1600. That was a trooper!
