[5] Socket M is used in all Intel Core products, as well as the Core-derived Dual-Core Xeon codenamed Sossaman.

It was also used in the first generation of the mobile version of Intel's Core 2 Duo, specifically, the T5x00 and T7x00 Merom lines (referred to as Napa Refresh), though that line switched to Socket P (Santa Rosa) in 2007.

It typically uses the Intel 945PM/945GM chipsets which support up to 667 MHz FSB and the Intel PM965/GM965 which allows 800 MHz FSB support, though the Socket M, PM965/GM965 combination is less common.

Pentium III-M processors designed for the first version of Socket 479 will physically fit into a Socket M, but are electrically incompatible with it.

[8] Although conflicting information has been published, no 45 nm Penryn processors have been released for Socket M. This computer hardware article is a stub.
