I'm considering to upgrade my T60 with a better CPU (possibly T7400 or T7600).

However I noticed that these CPU's are manufactured with 2 different package types:

- micro-FCPGA: micro-Flip Chip Pin Grid Array = 478-pin micro-FCPGA = socket M
- micro-FCBGA: micro-Flip Chip Ball Grid Array = 479-ball micro-FCBGA

as listed here:

Obviously I want to avoid purchasing the wrong type and the hassle to sell it again.
Question: which package type is compatible with my T60?

P.S.
In the meantime I´ve changed the subject of my post (T60 into T6X), because this issue might be relevant for both T60/P and T61/P owners, interested in a CPU upgrade

BGA=permanently soldered in cpu

So no, you can't find individual BGA cpus, there's no chance of accidentally getting one. They are used in non-upgradeable laptops like the X series.

aaa, thanks for your so revealing info!

I'm feeling so much comfortable now!

aaa, no offense to you of course, as your info was crucial to me.

Next post gives some more details, for whom are interested in the differences in FCPGA and FCBGA.

Currently a Dutch guy is selling a T7400 BGA version on the internet (www.marktplaats.nl), after he purchased it at Ebay and finding out that he couldn't use this version.
