MSI 915GM Speedster-FA4

Question

I've plan to purchase MSI 915GM Speedster-FA4 and combine it with my Pentium M 755 (479pin).
I searched the web for best price, but I found two different specification for CPU socket, one is Socket 478 and the other is Socket 479. Which one is correct info? ???

Answer 1

Actually the pentium M comes in socket 479, but according to intels site they do come in 2 different types Micro FCPGA & FCBGA.
and according to the sSpec# there is a 479pin version of the newer ones.
the  1.86 comes in both of the ways below - so make sure you get the SL7S9 if you were choosing between them.
SL7SR  1.86 GHz 533 MHz 90 nm C0 2 MB 479 pin 
SL7S9  1.86 GHz 533 MHz 90 nm C0 2 MB 478 pin
