Compatibility and revision notes
Check exact RAM SKU, M.2 key/interface, power source and case/cooler. ROCK 5B is distinct from ROCK 5A and ROCK 5 ITX; do not assume identical connector placement.
Socket, connector shape and family branding alone do not establish compatibility. Verify the exact processor list, minimum BIOS, memory population table, power input, dimensions, and shared-lane behavior in the cited manual before installation.
Preservation and repair
Inspect USB-C and M.2 standoff, maintain RK3588 heatsink contact, and record board revision and bootloader. Avoid powering through multiple inputs unless the documentation permits it.
For archival preservation, photograph the PCB, labels, connectors and included accessories before cleaning. Record serial/date codes, firmware versions, known faults, prior repairs and test conditions; use ESD-safe handling and do not power a board with loose conductive hardware beneath it.
