FM2 Socket CPU List: Every AMD Processor That Fits FM2 and FM2+ | The Board Decides

Socket FM2+ boards run both FM2 and FM2+ processors, but an FM2+ chip will not boot in an FM2 board — the extra contacts have nowhere to go.

A cheap Kaveri chip looks like a free upgrade for an aging Trinity build. Seat it in an FM2 board and the fans spin with nothing on screen, because the newer processor carries contacts the older socket never had. That one-way rule shapes half the shopping questions around these two AMD sockets before anything else matters.

What follows is the working model list for both sockets, then the check that settles whether a specific processor runs in a specific board — the step most people skip.

FM2 Vs FM2+: What Changes Between The Two Sockets?

FM2+ takes every FM2 processor and adds the Kaveri and Godavari generations. The reverse never works: an FM2+ processor will not seat in an FM2 socket because the chip has extra contacts the socket does not provide.

Both are desktop PGA designs. Neither shares a footprint with AM3, AM3+, AM4, laptop sockets, or soldered BGA chips, so a processor from any of those families is a non-starter no matter what a used-listing title claims.

• PCI Express 3.0: FM2+ boards enable it only with an FM2+ processor installed. Pair an FM2 chip with the same board and the slots drop back to PCIe 2.0.
• A hot 95 W APU in a thin OEM board is a cooling problem first and a speed problem second.
• Feature loss: FM2 chips generally boot fine in FM2+ boards, but they may skip FM2+-specific capabilities on the way.

The FM2 And FM2+ CPU List: What Fits Where

Four AMD desktop families cover these sockets — Trinity and Richland on FM2, Kaveri and Godavari on FM2+.

Two caveats travel with that list. Business and low-power variants carry B and E suffixes, and a board maker has to list each one individually before it counts. ASRock’s CPU support database separates FM2 from FM2+ boards and attaches exact BIOS requirements to individual entries — versions such as P2.10, P3.30, or P2.50 — so the model names above are the candidate pool, not a per-board guarantee. The ASRock CPU support list shows how granular those entries get.

Checking A Processor Against Your Board

The socket name is the weakest form of evidence available. The manufacturer’s CPU support list is the one that counts, and it is specific to the board model, the board revision, and the BIOS version already installed.

1. Read the exact model number off the motherboard, plus any revision code printed beside it.
2. Open that model’s CPU support page and search the processor by its full model name.
3. Note the minimum BIOS version listed for that chip and compare it with what your board runs now.
5. Cut power, lift the socket lever, line the gold triangle on the chip up with the triangle on the socket, and lower it without pressing.
6. Add fresh thermal compound, seat the cooler, plug the fan lead into the CPU fan header, then power on and open firmware setup.

The processor name appearing on the firmware screen is how you know the board recognized it. A black screen after a BIOS update that matches the support list points to a seating or cooler-mounting problem before it points to a dead chip.

Buying blind is where these builds go sideways. If you would rather work from a shortlist than from a model number, the tested FM2 processor roundup covers which of these chips are still worth fitting.

Work the order backwards when something feels off: board model first, support list second, BIOS third, physical install last. Skipping the second step turns a cheap processor into an expensive lesson.
