P3/p4 Question...need Help

post #1 of 8
Thread Starter 
My friend has a Dell with a P4 socket 478 and a dead motherboard. I have an old HP that has a good motherboard but a P3 cpu. Question, can I put a P4 cpu in a P3 mobo as long as both are socket 478, and if so will there be any side effects?? Thanks

You'll have to reinstall the operating system because it's a new motherboard, but if its the same socket chip, then it will work.

there are no p3's for 478, 478 is pentium 4 and celeron only, your p3 is 90% likely a socket 370

also, dell uses their own mounting pattern, the mobo will not fit in the case

I stand corrected, it is a Celeron, just checked. So if I buy a new mobo for the Dell it won't fit in the case???

Another reason to yell DELL HELL. I have a couple of old cases here, so I'll just order mobo and transplant to another case. Thanks.
