you need a really old mobo for that cpu
thats a socket 478 chip the latest are 775 - that cpu will not work on anything made in last 2 years
keep in mind you going down the wrong street, that cpu has use to only someone that needs one for an old system.
to put any money into that cpu is really waste, you can get a better celron for $20. i suggest you go with a new cpu that is cheap, low end core 2, can be found for $40 or less.
The mobo will be a lot less expensive and less headaches
I pulled the chip, it is most definatedly a 775 chip, @ the other poster i thought intel board had different voltages and fsb, and were not backward compatible, if thats the case i'll get a invida board.
