Socket S1g3 was the third socket for OPGA-638-packaged AMD mobile microprocessors with an integrated DDR2 memory controller, and the successor to Socket S1g2. Its counterpart for desktop processors is Socket AM2+, for servers Socket C32 and Socket G34. For the small form factor desktop, ultrathin mobile and embedded market AMD developed package ASB2. Socket S1g3 was superseded by Socket S1g4.

Socket S1g3 was used in AMD's "Tigris" mobile platform. All processors for Socket S1g3, codename "Caspian", are members of AMD's Family 10h with CPU cores based on the K10 microarchitecture.

All revisions of Socket S1 have the same dimensions, however processors for Socket S1g3 appear to be electrically incompatible with Socket S1g1. Socket S1g3 and S1g2 have the same pinout, if processors for these sockets are exchangeable is unclear. Socket S1g3 processors will not work in Socket S1g4 systems, which use DDR3 memory, but S1g4 processors which support both DDR2 and DDR3 memory may be compatible with Socket S1g3 if the BIOS recognizes the CPU.
