Need help figuring out processor sockets

[CurseTheSky]

I've done a bit of searching on Google, and I'm still not 100% sure what sockets these processors use. Unfortunately, I can't rip the systems apart at the moment (they're in continuous use), so physically seeing what socket they are is sort of out of the question.

Two of the processors are Pentium 4 3.0GHz. They came in Dell Dimension 8300s a few years ago. I know one of them supports HT, and I'm not sure about the other. Are these socket 478, or 775? Are they Northwoods or Prescotts?

A third processor is a Pentium 4 2.0GHz that came in a Hewlett Packard (unknown model). Again, 478, or something older? Northwood or *gasp* Willamette?

Finally, there's a Celeron 1.4GHz. I figured this is a Tualatin, but I wanted to double check to make sure.

Thanks.

download CPU-Z and run it on each computer. It will tell you all you need to know about the processors.

Stogez beat me to it. But yeah, CPU-Z will give you everything you need.

Unfortunately, I don't have access to them at all. I'm just trying to figure out what hardware they have so I can plan around upgrades for them.

how can you plan upgrades when you dont have access to them?
anyway, the Dells are probably s478 if they're more than 2 years old. I'm not sure which core but would say northwood.

They're computers that used to be sitting unused. Lately they've all (with the exception of the Celeron, which has no HDD) gone back into use. They're going to be presents for various people, but I'm trying to fit them with affordable upgrades where necessary.

For example, the Dells have just a heatsink on the processor, no attached fan. They RUN ok, but it's not something I'm particularly fond of.

Dell Dimension 8300 was Socket 478. Looks like Dell used both Northwood and Prescott in the 8300, but if I had to guess I'd bet on it being a Northwood.

Pentium 4 at 2 GHz could be Willamette (Socket 478 or 423) or Northwood (Socket 478). Without knowing the socket or L2 cache, no way to tell.

The only 1.4 GHz Celeron I'm aware of was indeed a Tualatin on Socket 370.

More here, here, and here.

Thanks a ton.

Any idea if HT was available on Northwoods? I heard somewhere it was Prescott only, but I can't confirm it.

Edit: Bleh. The only ones I can find that aren't newish are socket 478 anyway. Too bad, I was hoping to build a spare Core 2 Duo system piece by piece, and stick that thing in there to tide it over. Oh well.

I had a 2.4 Ghz Pentium 4 Northwood with HT. So yes, HT on Northwood is possible

Hyper-Threading originated with the Northwoods. It was available on all Northwoods with a 800 MHz Front Side Bus as well as the 3.06 GHz model with 533 MHz Front Side Bus. On other Northwoods with 533 MHz FSB, it was present but disabled.
