Socket FM2+
Socket FM2+ (FM2b, FM2r2) is a CPU socket used by AMD's desktop (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.x data rates. In addition, the Gfx link is capable of supporting PCIe  3.x data rate. 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.
