Dell M1330 processor upgrade

[Guest]

I have a basic M1330 for over a year now originally configured with the lowest CPU available which is the dual core T5250 at 1.5 and 667. I want to buy and upgrade the CPU. Intel says the socket for teh 5250 is PPCGA478. When I run CPUID it says socket P(478). When I search for dual core mobile CPUs at Newegg, the socket options are P or 478. How do I know for sure which CPU to get?

Your chip is a Micro-FCPGA package type, which is compatible with socket P:

Socket P is equipped with 478 pins, also - but Socket P and Socket 478 are not pin compatible.

In other words, Socket P is your winner.
