PURCHASE CHECKS
1. Keep the model suffix and ordering code. A CPU model, tray code and OEM upgrade kit can describe different purchasing units.
2. Check the server generation, firmware and thermal support. A matching socket does not by itself prove compatibility.
3. For a multi-socket system, verify pairing requirements and include the correct heatsinks and carriers in the same review.
4. Record whether the offer is production silicon, an engineering sample or a qualification sample. Do not infer its status from the model name.
5. Request top-side markings, package photographs and the stated test scope before accepting a substitution.

PHOTO / EVIDENCE REQUIREMENTS
Top-side markings
Package underside where safe
Carrier or protective tray
Heatsink if included
