SK Hynix 16GB DDR5-4800MHz PC5-38400 ECC Registered CL40 288-Pin DIMM 1.1V Single Rank x8 Memory Module — HMCG78AEBRA107N

The SK Hynix HMCG78AEBRA107N is a 16GB DDR5-4800MHz ECC Registered (RDIMM) server memory module operating at 1.1V with CL40 latency. Featuring a 288-pin DDR5 interface and Single Rank x8 (1Rx8) configuration, it delivers enterprise-grade ECC error correction for Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC (Genoa) server platforms requiring DDR5-4800 registered memory.

Key Features

  • 16GB DDR5-4800MHz ECC Registered DIMM for next-generation enterprise servers
  • DDR5-4800MHz (PC5-38400) for high-bandwidth DDR5 server memory performance
  • Registered DIMM (RDIMM) for stability in multi-DIMM DDR5 server configurations
  • Single Rank x8 (1Rx8) configuration
  • 1.1V operation — lower voltage than DDR4 for improved energy efficiency
  • 288-pin DDR5 interface — next-generation server memory form factor

Frequently Asked Questions

What is the difference between HMCG78AEBRA107N (16GB 1Rx8) and HMCG94MEBRA112N (64GB 2Rx4)?
HMCG78AEBRA107N is a 16GB DDR5-4800 RDIMM with Single Rank x8 (1Rx8) organization while HMCG94MEBRA112N is a 64GB DDR5-4800 RDIMM with Dual Rank x4 (2Rx4) organization — different capacities and chip organizations.
Is HMCG78AEBRA107N 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.

The SK Hynix HMCG78AEBRA107N 16GB DDR5-4800 ECC Registered DIMM delivers next-generation server memory performance for Sapphire Rapids and EPYC Genoa platforms. Order today for genuine SK Hynix DDR5 RDIMM quality.
