- Keep firmware/AGESA version and memory profile recorded; verify cooler contact and temperatures before sustained load. Confirm exact CPU support and any board BIOS requirements before installing.
- Before installation, compare the exact CPU marking with the motherboard maker’s support list, board revision, BIOS minimum, package/socket, power requirements, and memory type. Do not force a package into a socket.
Service & archival record
Keep firmware/AGESA version and memory profile recorded; verify cooler contact and temperatures before sustained load. Confirm exact CPU support and any board BIOS requirements before installing.
For a collection record, photograph both sides, retain the full model/OPN and date/lot codes, describe package and contact condition, and record the tested motherboard revision, firmware, cooling, memory, and measured operating conditions. Separate measured observations from published limits.
