    your MB is very old it will not support every P4, it will most likely not support any 800fsb and may not even support every 400/533fsb cpu, you have to list your MB make & model or check your MB manual

    also you do not have to reload Windows, just drop the new CPU in and your done.

    Had a look for th echipset, to see what it says. It will support an 800 FSB, so provided you dont exceed that it should be ok. Quick check shows that a P4 3.2 runs at 800 FSB (but check it yourself, to be sure) so i guess that should be ok. However you need to check your motherboard manual, or if you dont have one, the name of the mobo or computer, to really make sure.
    In terms of installing, the procedure is fairly simple usually, but you need to make sure it is done correctly, or no more computer.
    On the bright side, after installing a new chip, you should not have to reinstall windows.

    If you go from a 1.5 to a 3.4, chances are you will notice a huuuuuuuuuuuuge difference, in terms of loading, speed, etc. The increase in ram will have helped an awful lot, so if you do upgrade the cpu you should find everything a lot quicker :)

    The problem you are likely to encounter is the fact that Socket 478 processors ranged from 2.26Ghz. to 3.4Ghz. The caveat to this is some of these processors were manufactured using the 0.13 micron "Northwood" core, and some were manufactured using the 90nm "Prescott" core.

    Many boards that will support "Northwood" cored processors do not support "Prescott" cored processors.

    had to figure it was a bit more complicated than putting any old pent4 in the MB, I'm surprised all 478's went up to 800fsb

    certainly if you can put a 3ghz or more in your MB that would be worth thinking about

    I made a mistake in post #8. The clock speed in the socket 478 processors ranged from 1.4Ghz. to 3.4Ghz.

    If you have a Pentium 4 1.5Ghz. socket 478 it has to be a Williamette core with a FSB of 400Mhz.

    If you have an Epox board, somewhere on the board should be an Epox model number such as EP-4SGM8I. To know which processors are supported by your board you need to locate the Epox model number. Please locate the Epox number and post it.

    If you don't know what motherboard you have go here; http://www.gtopala.com/siw-download.html

    and download SIW 1.70. This is an executable that doesn't have to be installed on your machine. Just download it to the desktop and launch the application. After the application launches click on Motherboard in the left pane, and when the right hand side pane opens see what information it gives you for the board. Post the Motherboard Information.

    If you want to delete SIW 1.70 just right click on the desktop icon and delete it. You may want to keep it since it is handy for finding information for your machine.
