The Socket AM2 + is a processor socket for AMD processors of the Athlon 64 and Phenom family .

It differs from its predecessor, Socket AM2 , essentially only in the support of HyperTransport  3.0 and a separate power supply for processor cores and memory controller. It is therefore both mechanically and electrically compatible with the AM2 socket. According to AMD, both AM2 processors in AM2 + motherboards and AM2 + processors work in AM2 motherboards. However, the new functions can only be used if both components follow the AM2 + specification.

In September 2007, the mainboard manufacturers began to make their existing AM2 mainboards fit for use with AM2 + processors. A BIOS update is usually necessary in order to identify the new processor. The AM2 + processor then works in the old AM2 mainboard, but the advanced power-saving functions of the AMD K10 processors cannot be used. The first boards fully compatible with Socket AM2 + were presented parallel to the presentation of the first Phenom processors on November 19, 2007 and are based on the chipsets of the AMD 7 series chipset . In 2009, the successor, Socket AM3, came onto the market, which mainly differs in its support for DDR3 RAM .
