Technical specifications

AMD Athlon II P320 with Socket S1

Socket S1 is a 638 pin, low profile, ZIF, 1.27mm pitch socket.[1] It replaces the existing Socket 754 in the mobile computing segment (e.g. laptops).

Socket S1 CPUs can include support for dual-channel DDR2 SDRAM, dual-core mobile CPUs, and virtualization technology, and compete with the mobile Intel Core 2 processor series.[2]

Socket S1 Revisions

Different generations of processors used variant pinouts of the S1 socket; processors were not necessarily compatible with a socket even if they fit mechanically.
