Question about 3.2 P4 processors.

I have noticed that some Socket 478 processors have a letter at the end of the name of the processor. This is really bugging me because I don't know which one performs better or if there is even a difference! One would say Pentium 4 3.2 E while another would say Pentium 4 3.2 C !!! What does that mean? They are both (I believe) prescott, and are both 478 socket with 800 FSB and 3.2 ghz operating frequency. Can anyone help? I was going to buy the low priced one from newegg (3.2 E) for $214 but saw the 3.2C at a relatively close price.

Thanks for you help!
 
Actually: E = Prescott and C = Northwood

you did not ask but also: J = E0 Prescott with XD and F = E0 Prescott with x86-64

Thanks, which one would be best for 478 socket, assuming they are all at the same speeds? Thanks.
 
Oh, personal preference.. what will you be using it for?

The Northwood is slightly faster than the Prescott in most cases, with the exception of newer games and video encoding. (Prescott has SSE3 and things that know how to use that get a performance boost from the Precott)

So if you are a Gamer, Prescott, if this is an Office machine Northwood.

If you are doing a little of both, either will be fine for both jobs within a few % of eachother.

Oh, and Prescotts use more power / run hotter.

I just noticed it looks like this might be an upgrade?

Are you sure your current motherboard can run a 3.2? Not all S478's are compatable... (and even fewer can run Prescotts)

Oh? I'm not really sure if my motherboard can run it then. Because it is a Dell. Are you saying even if it is the same socket, it might not be able to run? Would that mean not run at all, or just not at capacity? What would I need to do to find out if it is compatible and would work?

Also, I believe my current PSU is around 230-350W (not sure can someone tell me how to find out as well) should I upgrade that too? Thanks.

Click to expand...

Might not run at all, in fact it might even damage things...

Why is that? How do I find out what Motherboard it is, and if it would damage it? Please help! Do I have to replace my mobo?!?! I really would like a new processor with my new card! Thanks.
 
The thing is, your motherboard has to support Prescott voltages and it needs to support the 800MHz FSB speeds. If it doesn't do the latter it won't do the first. So the 533MHz FSB Prescott's are out of the question as well.

As far as the motherboard goes, it helps to know what manufacturer made it. In the case of Dell you need the exact specs of the machine to find out. For example what processor do you have now? If you have anything without a FSB of 800MHz then it's doubtfull you can use a Prescott. If you've got a 800MHz FSB processor, A Northwood with HT, then it only will work if the board has support for Prescott voltages and the proper BIOS.
