Hey all, I just traded my Celeron 300A for a Pentium II 333, and to my surprise, this CPU is multiplyer unlocked! I thought all Intel's were locked internally? I can clock this puppy to 400 Mhz (6x66), but the cache disables itself at that speed, so I don't think there is any performance gain. I am gonna do the pin mod to this CPU to get it to auto-detect 100Mhz FSB...then I should have some fun!

Eah, to each their own, I'd have fun with an unlocked Intel chip, if only for my smug sense of happiness at stickin' it to the man!

If I remember correctly, early PII's were all multiplier unlocked.

Anthing under a PII350 should be multi unlocked. They didn't start locking the PII350's until a few weeks into production. I have one as a file server and it is locked <g> PII350@464
The week at which the PII350 started being locked was the week in which production of the PII400's which came locked coninsideed if I remember right(maby not), but being made on the same die that's when they should have started being made locked.

after august 1998 all multipliers were locked.
anything from before that date is potluck.
some were locked, some weren't and some were partially locked.
i had a PII 300 that was partially locked. you could lower, but not raise the multiplier.

Looktall is correct, the early P-II CPUs were unlocked, but after August 1998, all Intel processors were locked. I've had two P-II 233, one was unlocked and one was locked. My unlocked 233 would easily do 300 with default voltage. Not many 300 CPUs were unlocked, so congrats.
