Replacing Celeron-D with a Pentinum 4

Specs: Windows XP Home
I have an eMachine with a Socket 478 Celeron processor. Can I use a Socket 478 Pentium 4 processor as a drop-in replacement? Could it really be just that simple? THANKS.

U can use socket 478 p4 cpu,but first check your pc cpu support.

Just because a CPU is socket compatible doesn't necessarily mean it's compatible with the motherboard/chipset. As kuwese mentioned, check the CPU support list before you run out & buy anything. You didn't bother to list the model number of your eMachines, so there's nothing more we can do to help....

It's not as simple as you may think. for starters what pentuim 4 processor are you going to put in there? If your motherboard doesn't support an 800mhz FSB then the best you can do is a Pentuim 4 with a 533mhz FSB. Now it will def support that setup because the Celeron D's have a 533mhz FSB. But that's just one factor you have to look for. Another factor is if your Bios is microcoded to read it. Now I take it since the Celeron D's came out after the Pentuim 4 533mhz FSB processor versions then the Bios should be able to read that type of processor just fine, but the Bios made not read a Pentuim 4 800mhz FSB processor at all. So if you are trying to install a Pentuim 4 with a 800mhz FSB processor, those are two factors you have to look into before buying one. Remember just because it uses the same socket doesn't automaticly mean it will wor and that's where a lot of novice pc users make that mistake.

Sorry, didn't realize the answer(s) would be so involved. I have an eMachine T4510 in which I installed some RAM (that I thought was good) and it wouldn't boot; removed the RAM but it still wouldn't boot -- never even completes POST. Anyway, I swapped the processor with a known-good Dell Gx270 and the Gx270 worked so I know the processor's okay. What I'm wanting to do is put the processor in a eMachine T2885 with "2.8GHz Celeron" and an 845G chipset. Any help or advice would be appreciated, as this is the computer my fie uses as a self-employed medical transcriptionist.

If you are asking will a Intel 845G chipset support a Celeron D 2.8ghz 533mhz FSB processor then the answer is yes. The 845G chipset will support all the way to a Pentuim 4 3gz 533mhz FSB processor.

Actually, I'm trying to figure if I can simply pop out this Celeron (currently running on the 845G chipset) and drop a Pentium 4 in its place. i THINK it'll work but then I thought simply adding RAM would be a safe thing to do, too, so am looking for advice from someone who knows compatability better than I do.

It will work as long as it's a Pentuim 4 533mhz FSB version or lower. If it's a Pentuim 4 800mhz FSB version it will not work on an 845G chipset.

Check the spec number on the Pentuim 4 processor to see what version you have. For example "SL6K6" and go here to see which model it is and rather or not it has a 533mhz FSB or an 800mhz FSB.
