i have a centrino laptop motherboard with a 479 cpu socket. will a 478 centrino chip fit this socket. will i encounter compatibility problems? can anyone explain to me the difference between a 478 and 479 socket protocals?

thanx, keith

Well the socket 478 looks like this here, and if you can imagine a processor with an extra pin on it .. it would not be able to fit in that socket .. not to mention that the ?pin out's? (what each pin is used for) for socket 478 and 479's are different. So if you felt :evil: one day and decided to brake the extra pin off to make it fit, you would be out of luck ;)

that?s the physical constraints, not to mention that the different sockets reside with different chipsets (not all processor can work with the same chipsets), and also the BIOS on the mobo you are using will not recognise it, as it is configured for a different spec processor.

so unfortunately the answer to your question is there is no way it will work .. and also the laptop is designed to work with a centrino/dothan which dissipates less heat and therefore the heatsink etc will be incompatible .. or insufficient in your case ..

hope this helps, and welcome to the forum :)


EDIT: ohh and dothans were never produced on the socket 478 platform, that was the pentium 4 "Northwood core" along with the Celeron ;)

As long as it's a pentium-m it will work. A desktop based socket 478 chip will not work(ie. pentium 4 or mobile pentium 4). There are 533mhz FSB and 400mhz FSB pentium-m's so you would have to be sure your motherboard supports 533fsb if you were to get a 533mhz FSB pentium-m.

wasn't all pentium M's socket 479 ?

thanks for the reply and the welcome.

my question arises from a perusal of a web site (xpcgear.com) selling centrino chips that indicated that the chips ( Intel's M 725/M 730/M 735 etc.) would work for both socket 478 and 479 applications. so....what's up with that?

do you have a direct link to the processor in question, because all of the 7xx series centrino dothans are socket 479.

EDIT: i think the ?Intel Pentium 4 M? will work (not the normal pentium 4, the mobile version), .. but the Centrino is exclusively for socket 479.

No, a pentium 4m will NOT work. Pentium-M's and Pentium-4's are not electricly compatible and pentium 4M's are just pentium 4's that will run on a lower voltage. There are some 478 pin pentium-m's if you look at the intel proccessor spec finder, such as this one.

yeah i wasnt to sure on the pentium 4 M, but as you say it obviously doesn't work, anyways i didnt realise that there was a socket 478 pentium m, what core is that ?

huh that is a 7 series aswell :confused: ..

I joined these forums for the information I could get!!

But it appears that one of the benefits of being a member of these forums is the comedic value!!
Way too funny!!!

You can't put a P4\P4-M (S478) in a S479 Socket. You can do the reverse though, on some ASUS mobos, with the CT-479. This allows you to run a Pentium M on the desktop, as it's basically a socket-converter. Unfortunately, its currently limited to certain ASUS boards, and I'm not aware that it'll work with others.

I've personally never heard of or seen a S478 Pentium M. The only possible explaination that I can give for those is that, if there were\are S478 P-M's, then they are the earlier ones (Banias Core), not Dothan. Because as far as I know, Dothan is exclusive to S479 ;) .

If you look at the intel proccessor spec finder, there are both banias and dothan 478 pin, B1 and C0 revisions, 400mhz FSB and 533mhz FSB, the only thing that appers differant is 1 pin..but they all go in socket 479 motherboards.

ok, they are all 'technically' 478 pin, Intel changed it to 479 pin when there was too much condusion. A 479 processor WILL NOT work on a 478 board!!!
