Compatibility and revision notes
Do not assume all AM4 CPUs/APUs are supported. The top M.2 and PCIe generation depend on CPU; the second M.2/SATA options may share resources. Fit the correct Wi-Fi antenna leads and use the manual's DIMM population order.
Physical socket fit alone does not establish compatibility. Verify the exact processor support list, minimum BIOS, memory population rules, case dimensions, power connectors and shared-lane behavior in the cited model documentation before installation.
Preservation and repair
Inspect AM4 socket pins on the CPU (the socket is pin-grid-array), board VRM heatsink contact, M.2 standoffs and rear-I/O Wi-Fi antenna connectors. Use BIOS Flash BIOS instructions only for this exact board model and retain stable power throughout firmware recovery.
For an archive record, photograph the PCB and labels before cleaning; note serial/date codes, BIOS/BMC versions, accessories, known faults, repairs, and test conditions. Use ESD-safe handling and never apply power with loose conductive hardware beneath the board.
