This article is part of the CPU socket series

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 the 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 ×16 core and two 5 ×8 cores, for a total of 64 lanes. 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).

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 (µBGA906).

  2. ^ Unified shaders : texture mapping units : render output units
  3. ^ To feed more than two displays, the additional panels must have native DisplayPort support.[9] Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed.
  4. ^ To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
  5. ^ a b DRM (Direct Rendering Manager) is a component of the Linux kernel. Support in this table refers to the most current version.
