This article is part of the CPU socket series

Socket FM2+ (FM2r2) is a CPU socket used by AMD's desktop "Kaveri" APUs (Steamroller-based) and Carizzo APUs (Excavator-based)[1] 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" are compatible with FM2+ socket.[2]

  • ECC DIMMs are supported on Socket FP3 but not supported on the Socket FM2+ package. GDDR5 memory is not supported at all.[3]
  • There are 3 PCI Express cores: one 2 x16 core and two 5 x8 cores, for a total of 64 lanes. There are 8 configurable ports, which can be divided into 2 groups:
    • Gfx-group: contains 2 x8 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 x16 link.
    • GPP-group: contains 1 x4 UMI and 5 General Purpose Ports (GPP).

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.[3]

For available chipsets consult Fusion controller hubs (FCH).

Its mobile counterpart is Socket FP3 (BGA-???).
