The "450A" doesn't exist as such, it is an unofficial name given to the end result of overclocking a Celeron 300A to 450MHz. This gives pretty good success rates, particularly with PPGA style processors. Exact numbers are anyones guess but most people seem to think it's over 75%. With the price of PPGA 300A's today, it is an extremely inexpensive way to get approximately P2-450 performance. As for your lack of luck getting Celerons to 100MHz bus speeds, what speed chips have you been trying to overclock? I ask because the average capability of the Mendocino core (although ever changing) seems to be around 450-500MHz. Some are better or worse, but because of this many 333MHz and up Celerons won't hit 100MHz bus because their core can't take it. 300A's are the natural choice, as their fixed 4.5x multiplier on a 100MHz bus gives a core speed that is obtainable by the majority of chips (450MHz). Also, use of a quality motherboard is helpful in overclocking. Tom Embt tom@embt.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
