Service and archival notes
Record CPU sSpec, BIOS microcode, motherboard power limits, cooling and memory configuration. Verify 300-series support list and inspect socket contacts.
Preserve provenance and a record of the exact marking, condition, tested board/platform, firmware, cooling, memory configuration, and test conditions. Separate published specification limits from observations made on a particular surviving system.
