CPU Compatibility Checker
Check your CPU, motherboard and RAM work together before you buy. Verifies socket, chipset, memory generation, capacity and BIOS updates.
What has to match for a CPU to work
Four things have to line up before a processor will run in a given board: the physical socket, the chipset's support for that specific chip, the memory generation, and the BIOS version on the board. Getting the first three right and the fourth wrong is the most common and most frustrating build failure.
Socket
The socket is the physical interface — AM5 for current AMD, LGA1700 and LGA1851 for recent Intel. A processor simply will not fit a board with a different socket. Note that a shared socket does not guarantee support: AM4 spans several generations, and not every board runs every chip.
Memory generation is decided by the board
AM5 is DDR5 only. LGA1700 exists in both DDR4 and DDR5 variants, and the two are physically keyed differently, so you must match your memory to the board you buy rather than the processor. Check the details with the RAM Compatibility tool.
BIOS support is the trap
A board manufactured before your processor existed may need a firmware update to recognise it — and updating usually requires a working CPU already installed. Many modern boards include BIOS Flashback, which updates from a USB stick with no processor fitted. If yours does not, buy a board with a sticker confirming support for your chip, or plan to borrow an older one.
Do not forget power and cooling
Compatibility is not only electrical. A 250 W processor on a budget board with weak voltage regulation will throttle under sustained load. Confirm your cooler fits and can cope using the CPU Cooler Compatibility tool.
Frequently asked questions
Will any AM5 CPU work in any AM5 motherboard?
Electrically yes, but a board made before a given chip launched may need a BIOS update first. Boards with BIOS Flashback can be updated without a CPU installed, which removes the risk entirely.
Can I use DDR4 memory with a DDR5 motherboard?
No. The two are physically keyed differently and electrically incompatible. The board decides which you need, so check its specification before buying memory.
Do I need a high-end chipset?
Only for overclocking or lots of high-speed connectivity. A B-series board runs a high-end CPU perfectly well for gaming. What matters more is the quality of the voltage regulation, which varies widely within a chipset tier.
What happens if I install an unsupported CPU?
The system usually fails to POST - no display output, and often a diagnostic LED for CPU. Nothing is damaged; the board simply does not recognise the chip and needs a BIOS update.
