Frequently Asked Questions

What is the difference between HMCG78MEBEA081N (UDIMM) and HMCG78MEBRA113N (RDIMM)?

The HMCG78MEBEA081N is an ECC Unbuffered DIMM (UDIMM) for workstations and entry-level servers, while the HMCG78MEBRA113N is an ECC Registered DIMM (RDIMM) for enterprise servers requiring registered buffering for multi-DIMM stability.

Is this module compatible with Intel Xeon Sapphire Rapids?

Yes, the HMCG78MEBRA113N is compatible with Intel Xeon Scalable Sapphire Rapids server platforms supporting DDR5-4800 ECC RDIMM. Verify your specific server”s QVL before ordering.

Is DDR5 backward compatible with DDR4 servers?

No. DDR5 uses a different physical connector and is not backward compatible with DDR4 server platforms.
