How can i find my cpu socket type ?

[frankd]

Hi all.
I'm the proud owner of a T41 , for which i'd like to upgrade the cpu but i can't find out what kind of socket my Centrino 1.5 is running on.
I don't really want to try my luck with opening the laptop case and all just to look at the cpu model number to then reclose it , buy a new cpu and re-open it again.

This is what i've found out:
my ibm is a type 2373-3JG
I'm running with a 400 MB bus
My chipset is an Intel 855PM (but i think this is standard)

Is there any software that can tell me if my Centrino 1.5 is using a Socket 479 or a 478?
I know, it's only 1 pin more/less but that makes a hell of a lot of a difference!

PS: I'm running Linux

Many , many thanks

Welcome to the forum!

The question you ask has been discussed quite a few times on this (outstanding!) forum, and I trust that you will benefit from browsing e.g. the following threads - while planning to speed up your old work-horse! See: What is the fastest processor for a T41? and T41 Processor upgrade and New T40 owner, new upgrade race!! and T4x Banias to Dothan Upgrade - Proper Stepping Required! and Upgrading processors in my T41? - all of which were quickly found if using the (very powerful!) Search function available on this forum, and searching for "t41 cpu upgrade" (remember to check "Search for all words" and restrict your search to the T4x forum).

Good luck with the upgrade - and start prepare yourself for a speedy future!

Best regards,

Johan

Hi Johan and thank for the welcome.
Yes this forum IS great for any Thinkpad lover.
I've followed the links you gave me , and i've found one answer to my question:

I think socket 478 is the older name for what later became socket 479. It's rather confusing, but because there already existed a Pentium 4 socket called "Socket 478" and the Pentium M's socket was also "socket 478" having 478-pins, they eventually renamed it socket 479 to differentiate between the two because the P4 and P-M sockets were incompatible.

but the guy wasn't too sure.
Is it possible to confirm such news ie that Socket 478 and Socket 479 are two different name for the same thing?

Many Thanks

Oh, well, I agree with you that this is a bit confusing, but fortunately we both have the "Search" function on this forum (remember?), and Google is also your friend... so using these nice, free tools I found a few more links that should (hopefully!) definitively answer your questions. Read: Why is there 478 and 479 pins Pentium M?? and Intel's 479 Socket Explained and Compared to the 478 and Will T40 work with this Dothan processer? and Upgrading processors in my T41? and How many pins does the T41 Banias have?

OK?

BR,

Johan

Johan,
sorry, i thought i did my searches.
Thanks for your patience and for providing those great links that answered my question completely.
It's all clear now!
