'''Socket AM3+''', also known as AM3b and AM3r2, was the socket for '''OPGA-938''' and '''OPGA-940'''-packaged [[AMD]] microprocessors with an integrated DDR3 memory controller and the successor to {{\\|Socket AM3}}. Socket AM3+ targets the desktop segment. Its contemporaries are {{\\|Socket S1}} for mobile processors, {{\\|Socket C32}} and {{\\|Socket G34}} for the server and workstation market. For the small form factor desktop, mobile and embedded market AMD developed package {{\\|ASB2}}. Socket AM3 was superseded by {{\\|Socket FM1}} and {{\\|Socket AM4}}.

Socket AM3+ processors use the OPGA-940 package and are compatible with the earlier Socket AM3, subject to the motherboard recognizing the CPU and the limitations of Socket AM3. The OPGA-940 package for Socket AM3/AM3+ has the same dimensions but is mechanically, due to keying, and electrically incompatible with {{\\|Socket 939}} for processors with a DDR memory controller, {{\\|Socket 940}} for first generation Opteron processors, and {{\\|Socket AM2}} and {{\\|Socket AM2+}} for processors with a DDR2 memory controller.

"Socket AM3b Design Specification", AMD publication #48988, specifies another package type with 941 pins. This package is keyed to be mechanically compatible with Socket AM3+ only.

Socket AM3 processors use the OPGA-938 package and are compatible with Socket AM3+, subject to the motherboard recognizing the CPU. The OPGA-940 package for Socket AM2/AM2+ differs from the OPGA-940 package for Socket AM3/AM3+ by keying and electrically. The former carries CPUs requiring DDR2 SDRAM, the latter processors supporting DDR3 SDRAM exclusively. Socket AM2/AM2+ processors are therefore incompatible with Socket AM3+.
