Socket FM2+ (FM2b) is a CPU socket used by AMD's 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 FM2+ socket.[1]
- ECC DIMMs are supported on Socket FP3 but not supported on the Socket FM2+ package. GDDR5 or HBM memory are not supported.[2]
- 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.[2]
For available chipsets consult Fusion controller hubs (FCH).
Its mobile counterpart is Socket FP3 (BGA-???).

- ↑ To feed more than two displays, the additional panels must have native DisplayPort support.[5] Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed.
