Mobile P3 1ghz..socket 478...20W.

Never heard of such a chip. If can really work in a modern 478 board, it would make a cheap alternative to a P4-M. According to the specs, it only uses 20W......like a P4-M.

Wheels spinning in head.......

That is very interesting...I checked Intel's website thinking the site had a typo and indeed they do have a Socket478 P3, with 512KB L2 cache as well. I'm not sure whether it has support on modern chipsets, though. The trail ran cold here.

I think that's a different socket 478, in other words you cannot use mobile PIII's with your P4 socket 478 (intel is great at confusing end users with their socket numbering).

If you want low power socket 478 look into mobile celerons. They go from 1.4Ghz up to 2.4Ghz and with a little modding most of them will work with your regular Socket 478 motherboard. According to intel they only consume 35W. I have 1.8Ghz in one of my PCs with zalman 7000 installed on it (with no fan though) and only one case tricool antec fan on exhaust and it idles at 37C. Not bad for fanless heatsink that's not really optimized to run passive.

hm.. if u have a s478 board its almost worth trying..

but, its not like P4-Ms are atall expensive on ebay.. sure they could be had for $18.

..pehaps email the site about compatible motherboards..?

I'm guessing this CPU is designed for embedded circuit boards and has the same socket type as the P4 to consolidate their CPU sockets. These CPU are sold to the industrial sector for making things like medical equipment.

I once sold one of these on ebay....only got around 5quid for it....

I should have told you guys first....

did u ever get it to work?

One big advantage of this chip (if it really works) is that it could work on countless 478 boards.....some of which are really cheap. This chip and a board for <$50.

P4-M boards, only three or four available, cost about $200 or more.

As a quiet project computer, this might make a really cheap, silent computer.

I'd say it's almost impossible to tell which CPU will work with what mobo in some cases. These are all the S478/479 CPU's listed at Intel, and if you start locking at them and count the pins I guess maybe none of them have 479 pins. Some of them are pretty much the same, and some are quite uncommon.
What a mess.

Bluefront: It has a 133 MHz FSB, not P4 style 4x100 MHz or more, I highly doubt it will work.
Yes, 478 pins, but the buses have just as much in common as a regular P3 and a P4 does.

An Asus mobo, a CT-479 and a PM is your best bet. It will cost you more (mobo and adapter starting at $100) but it will work. I know you're handy enough to make any cooler fit that mobo. And I won't tell you to buy an AMD instead, I know better than that.

don't u mean P-M?
..p4-m works in normal motherboards??

Yet again Intel confusing names take another victim. Thought I'd step in just to say Mobile Pentium 4 M's do work in normal socket 478 motherboards (and very well I might add), Pentium M's do not. I actually have one of these socket 478 mobile P3's around here somewhere (might have been the person who bought it off you Gojira-X because I got it cheap) but unfortunately they have a different pin layout (at least 1 pin is in different location) and I didn't fancy breaking it off to test as I don't have a spare s478 board I'm willing to sacrifice.
