FM2 Socket CPU List | All AMD FM2 And FM2+ Processors

Socket FM2 boards take Trinity and Richland A-Series chips; FM2+ boards add Kaveri, Godavari, and Carrizo and can still run most FM2 processors.

A socket mismatch is the usual reason a used APU won’t post. FM2 and FM2+ boards look nearly identical — same cooler brackets, DDR3 slots, and retention frame — yet their processor lists cross over in only one direction. Check the FM2 socket CPU list against the board maker’s support page before buying.

AMD launched desktop FM2 on October 2, 2012 for second-generation A-Series APUs. Both platforms are long discontinued, so everything below comes from manufacturer support lists rather than a current AMD product page.

What’s The Difference Between FM2 And FM2+ Sockets?

An FM2+ processor needs pins an FM2 socket lacks and will not work in an FM2 board at all; an FM2 processor usually works in an FM2+ board once the BIOS supports it.

Both use dual-channel DDR3, with FM2 rated to DDR3-1866 and FM2+ to DDR3-2133. FM2 boards commonly run A55, A75, or A85X chipsets; FM2+ boards use A58, A68H, A78, or A88X. PCI Express 3.0 appears on FM2+ boards only with an FM2+ processor installed — an older FM2 chip can drop those slots to PCIe 2.0 speeds.

FM2 And FM2+ CPU Lists By Family

Every FM2 and FM2+ desktop chip is an A-Series APU, an Athlon X4, or one of three FX-branded models, grouped here by socket and family.

Integrated graphics are the split that bites buyers. A-Series chips include Radeon graphics — HD 7660D on the A10-5800K, R5 or R7 on Kaveri parts — while Athlon X4 and FX-branded FM2+ models have none and need a discrete card. The A10-5800K pairs four cores with a 100 W TDP; FM2+ desktop chips run two to four cores at 45–95 W on 28 nm. FM2+ lists also turn up low-power Athlon 5150 and 5350 variants, whose support varies by board.

How To Check Compatibility Before You Buy

A socket label alone never confirms a match — the exact board model, revision, CPU stepping, and minimum BIOS version decide it.

1. Find the exact model and hardware revision, printed on the board and listed in the manual.
2. Open the manufacturer’s CPU Support List for that model.
3. Search the exact processor model, not just the family name.
4. Confirm the required BIOS version and the board’s supported TDP.
5. Flash that BIOS with the old processor installed, following the maker’s documented method and never cutting power mid-update.
6. Shut down, unplug AC, discharge the system, remove the cooler, clean off old paste, align the CPU’s corner marker, and lock the socket without force.
7. Fit a cooler rated for the new chip’s TDP, connect its fan, and let the board POST.

ASRock’s FM2 CPU support database shows how granular this gets: it names the socket, chipset, board model, CPU revision, wattage, and required BIOS version, with entries like P2.00, P2.10, and P2.30. Other board makers publish the same table.

Recognition is the tell. The POST screen and BIOS should report the exact processor string and core count; a board that hangs at the logo, spins fans at full speed, or lists the wrong model usually needs a BIOS re-flash or a lower-TDP chip. Once the socket question is settled, our tested FM2 processor picks for older boards narrows the shopping question. There is no current AMD retail pricing for any of these chips, so used listings vary by seller and condition.

• Treating FM2 and FM2+ as interchangeable because the sockets look the same.
• Assuming every FM2+ board runs every FM2+ chip — plenty need a specific BIOS first.
• Ignoring board revision, which can change CPU support within one model name.
• Dropping in an Athlon X4 or FX-branded FM2+ chip without a discrete graphics card.
• Equating “quad-core” across families — cache, clocks, TDP, and graphics differ.
