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. The "Sossaman" Xeons use the E7520 chipset.

Relation to other sockets

Socket M is pin-compatible with desktop socket mPGA478A but it is not electrically compatible. Socket M is not pin-compatible with the older desktop

Socket 478 Socket 478, also known as mPGA478 or mPGA478B, is a 478-contact CPU socket used for Intel's Pentium 4 and Celeron series Central processing unit, CPUs. Socket 478 was launched in August 2001 in advance of the Northwood core to compete with AMD ...

(mPGA478B) or the newer mobile Socket P (mPGA478MN) by location of one pin; it is also incompatible with most versions of the older mobile Socket 479. 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. Although conflicting information has been published, no 45 nm Penryn processors have been released for Socket M.
