Compatibility and revision notes
AM5 requires DDR5 and does not accept AM4 CPUs or DDR4. Confirm BIOS support for the exact Ryzen CPU and check reduced I/O/M.2 availability with selected 8000-series processors.
Socket, connector shape and chipset branding alone do not establish compatibility. Check the exact board revision, CPU support table, minimum BIOS, memory population rules, power connectors, case clearance and lane-sharing details in the cited documents.
Preservation and repair
Protect AM5 socket contacts and inspect Wi-Fi antenna sockets, M.2 retention and ATX power connections. Use only MS-7D78 firmware and its documented flash procedure.
For archival preservation, record PCB revision, serial/date codes, installed firmware, known faults, repairs and test conditions. Use ESD-safe handling and do not power a board with loose conductive hardware beneath it.
