  1. Hello , I have an hp a305w(mobo specs below) with a 2.7ghz celeron processor and someone gave me a dell (bad power suppy) with a 2.9ghz P4 processor. Both are 478 pin and mobo specs say it supports P4 also. I swapped the chips out Perfect fit, and the computer will not boot with the new P4 , only boots w/the old celeron. Powers on and the fan works just wont boot with the P4 processor. Am I missing something? Is it more than just a chip swap? heres the mo specs.

    The Pentium 4 maybe dead, if the power supply killed it while it was in the other computer.

    Its not,I verified this in the dell. The power supply just randomly shuts the dell off, green light and all, it just wont stay running more than a couple minutes.

    It doesn't say the motherboard supports all Intel P4s, just Willamette and Northwood. Perhaps the Dell P4 belongs to another family (like Prescott) or perhaps it is a Dell special proprietary P4.

    P4G533 - there's your answer.

    It appears to support 533MHz FSB {not the 800MHz of later P4's}

    Your new CPU isn't compatible with the Motherboard unfortunately, coz it'd be considerably faster.

    Actually the 845GL chipset doesn't support any FSB above 400MHz so it's almost sure that P4 will not work on that motherboard.
