Same here...a friend of mine has a Celeron 300A, which is
normally clocked at 66 x 4.5 (multiplier locked) on an LX
motherboard. He put it on a BX motherboard, and boom, 100 x 4.5
= 450 mhz. This works really well with no more fans than usual
(well, the heatsink on his chip has two, but other than that...). This
works a lot better than a PII 300 standard, because the 128 kB
cache (plenty to hold the RC5 code, I think) is on-die, not just on
chip as with the PII. Also the heatsink & fans are closer on Celeron.
There were also a few PII-300s made before August or something
(there's a code on the chip to check for) that are actually PII-
450s...oops Intel. Trust me -- the marks are identical. It isn't
overclocking on that chip. Too bad they're impossible to find, and
most of the people who have them probably don't know it.
