Haha. Many of you will laugh at me for asking this. I know how to install a P4 Socket 478 Processor, but I can't seem to figure out how to install/uninstall a P3/Celeron Socket 370 Processor. The reason why I'm asking this is that I wan't to take out a perfectly working P3 1GHz CPU and put it on my Celeron 633. Do you know how I can do this?

Haha, P4 boards are automatic transmission, and Celeron / PIII are stick shift, you know how to drive an automatic but not manual shift.

PIII 1ghz is either 100 or 133FSB and Celeron 633 is 66mhz FSB. Either the board has jumper settings for the FSB or does not.

Before you do that, make sure your motherboard supports it. Its not that hard to take out the Celeron on your machine. First you take off your heatsink, then take out the CPU, there should be a stick next to the socket where you can pull it up @ 90 degrees so you cpu will pop out, then you can take out the CPU from there.

Ok Thanks for replying TMP-Man and real cool. I'm going to see if my motherboard supports it and if it does, I'll change it.

Arg... my Mobo does not support the P3 CPU. So I can't change it. Thanks for your help anyways.

How do you find out whether or not you can upgrade your CPU? I'm running a 1GHz PIII and want to go a bit faster. Can someone please help me??

Chris,
check the manual and the manufacturer site of your board if the socket370 is FCPGA (also written FC-PGA) or FCPGA2. There is a difference because at least two pins are wired differently.
Also check if the board supports 133MHz FSB.
And check if you have a FCPGA or FCPGA2 cpu.

If your board is FCPGA I have bad news because the fastest FCPGA Celeron and Pentium3 (Coppermine Core) run with 1,1Ghz so an upgrade doesn't make sense.
But if you cpu is a FCPGA2 (they overlap at that speed) you may try one of the faster FCPGA2 cpus but I'm not sure it works!
The problem is that someone here said a FCPGA2 works on FCPGA but as I upgraded my old slot1 board with help of a slot1 to socket370 FCPGA adaptercard every site stated that it won't run with FCPGA2 cpus. I'm not sure if it's a problem of the 2 socket versions or the controller on may slot1 board.

If you board is FCPGA2 you can theoretically go up to the fastest socket370 FCPGA2 cpu but better recheck with the manufacturer if it works because there can be reasons like a different cpu voltage (VCore) that it won't work.

Sorry, but that's all I can say. I hope it helps!
