Confirmed = listed in the vendor's memory documentation for this server. Vendor match = the vendor's own part cross-reference matches the module and its speed is validated for the platform; not taken from this server's memory list. Spec match = meets this platform's JEDEC requirements (generation, form factor, validated speed); interchangeability is spec-based, not per-server testing. How we verify →
