Frequently Asked Questions

What is the difference between HMCG88AEBRA107N (2Rx8) and HMCG94MEBRA112N (2Rx4)?

Both are SK Hynix DDR5-4800 ECC RDIMM modules. HMCG88AEBRA107N is a 32GB 2Rx8 module while HMCG94MEBRA112N is a 64GB 2Rx4 module — different capacities and chip organizations.

Is HMCG88AEBRA107N compatible with Intel Xeon Sapphire Rapids?

Yes, it 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 slots?

No, DDR5 is not backward compatible with DDR4. DDR5 RDIMMs require DDR5-capable server platforms and cannot be installed in DDR4 memory slots.
