piii processors can have either a 100 or a 133 front side bus speed (fsb).
i don't think that the 800mhz was made with a 100fsb and so assume that it
is 133 (you can look up your exact model number on intel.com to find out).
if your 800mhz processor has a 133mhz front bus speed then it has a fixed
multiplier of 6 (800/133=6) and so when you stick it into a machine that
only supports a 100mhz fsb it will only run with an internal speed of 600mhz
instead of the rated 800mhz. that makes it not worth the effort. you would
be better off buying the powerleap upgrade for about $100 with the newer
type celeron 1.4ghz which has a 100mhz fsb (older socket 370 celerons had
66Mhz fsb)... but keep in mind that spending $100 on memory and $100 on
this processor upgrade and possible $100 on a new hard drive is a big price
tag to pay when you consider that dell had a p4
2.7/128mb/80gb/cdrw/17"crt/winxp home/keyboard/mouse/free shipping for $350
after the $100 rebate. that deal may be over but it comes around
frequently...
