This article is part of the CPU socket series

Socket FM2 is a CPU socket used by AMD's desktop Trinity and Richland APUs to connect to the motherboard as well as Athlon X2 and Athlon X4 processors based on them. FM2 was launched on September 27, 2012.[1] Motherboards which feature the new FM2 CPU socket also utilize AMD's new A85X chipset.[2]

The socket is very similar to FM1, based on a 31×31 grid of pins with a 5×7 central void, 3 pins missing from each corner, and a few additional key pins missing. Compared to Socket FM1, two key pins were moved, and one more is removed, leaving 904 pins.[3]

For available chipsets consult Fusion controller hubs (FCH).

Steamroller-based "Kaveri" APUs are not supported, see Socket FM2+ (FM2r2) and Socket FP3 (BGA-???).[4]
