OEM cross-references are compiled from distributor cross-reference data and OEM documentation. Verify against your vendor's parts list before ordering.
Server compatibility checks review the evidence for each match
Confirmed = a reviewed primary document lists this exact part for that server. Vendor match = reviewed OEM documentation supports the exact OEM part for the server; a native part also requires a separately reviewed OEM cross-reference. Preliminary match = generation and DIMM type match, with no conflict in the capacity limits recorded here. Capacity, ranks, CPU, BIOS and population rules may still need verification. Confirm the exact part and revision against the server documentation before ordering.
The catalog groups these part-number variants by matching recorded specifications. Confirm the exact suffix, revision and server qualification before substituting; the grouping does not verify that their hardware is identical.
Same-spec candidates matching catalog values · verify before substituting
Candidates match five catalog values: generation, module type, capacity, rated speed and organization. This does not verify those values or establish interchangeability. Check CAS latency, the exact part and revision, server support and population rules before substituting.
These are catalog comparisons, not per-server qualification or testing.View the full family →
