Socket AM2+ is a CPU socket, which is the immediate successor to Socket AM2 that is used by several AMD processors such as Athlon 64 X2. Socket AM2+ is a mid-migration from Socket AM2 to Socket AM3 and both AM2+ and AM2 socket CPUs and motherboards have the potential to operate together. Actual interoperability depends upon other factors, especially the availability of compatible BIOS software, and some PC retailers, such as Dell, have not provided compatible BIOS versions that allow use of socket AM2+ CPUs on their products utilizing socket AM2 motherboards, such as the Inspiron 531.

The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors), is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. It was released on May 23, 2006, as a replacement for Socket 939 & Socket 754.
