I am just wondering if I am able to fit an intel 875P chip into the P4P800 Deluxe motherboard which has a chipset of 865PE? Both are of socket type 478... Any information is appreciated.
In addition to what Ninja Fetus has said, you can only use a Socket 478 CPU. The newer LGA775/Socket 775 CPU's are physically incompatible with the CPU socket on that motherboard.
