OEM cross-references are compiled from distributor cross-reference data and OEM documentation. Verify against your vendor's parts list before ordering.
The preliminary rows are a sample across vendors: 99 further platforms share this generation and DIMM type without a recorded capacity conflict. This is not a qualified-parts list. Browse all servers →
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.
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.
