Socket FM2+

Socket FM2+ (FM2b, FM2r2) is a zero insertion force CPU socket designed by AMD for their desktop "Kaveri" APUs (Steamroller-based) and Godavari APUs (Steamroller-based) to connect to the motherboard. The FM2+ has a slightly different pin configuration to Socket FM2 with two additional pin sockets. Socket FM2+ APUs are not compatible with Socket FM2 motherboards due to the aforementioned additional pins. However, socket FM2 APUs such as "Richland" and "Trinity" are compatible with the FM2+ socket. All PCIe links are capable of supporting PCIe 2.0 data rates. In addition, the Gfx link is capable of supporting PCIe 3.x data rate.
 * ECC DIMMs are supported on Socket FP3 but not supported on the Socket FM2+ package.
 * There are 3 PCI Express cores: one 2 ×16 core and two 5 ×8 cores. There are 8 configurable ports, which can be divided into 2 groups:
 * Gfx-group: contains 2 ×8 ports. Each port can be limited to lower link widths for applications that require fewer lanes. Additionally, the two ports can be combined to create a single ×16 link.
 * GPP-group: contains 1 ×4 UMI and 5 General Purpose Ports (GPP).

For available chipsets consult Fusion controller hubs (FCH).

Its mobile counterpart is Socket FP3 (μBGA906).

Heatsink
The 4 holes for fastening the heatsink to the motherboard are placed in a rectangle with lateral lengths of 48 mm and 96 mm for AMD's sockets Socket AM2, Socket AM2+, Socket AM3, Socket AM3+ and Socket FM2. Cooling solutions should therefore be interchangeable.
