Frequently Asked Questions

How does HMCGM4MEBRB233N achieve 96GB capacity?

The 96GB capacity is achieved using 48Gb die technology in a Dual Rank x4 (2Rx4) configuration — a higher-density die generation compared to standard 32Gb or 16Gb DDR5 dies used in 64GB 2Rx4 modules.

Is HMCGM4MEBRB233N 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 for 96GB RDIMM support before ordering.

What is the difference between HMCGM4MEBRB233N (96GB) and HMCG94MEBRA112N (64GB)?

HMCGM4MEBRB233N is a 96GB DDR5-4800 RDIMM using 48Gb die technology while HMCG94MEBRA112N is a 64GB DDR5-4800 RDIMM — the 96GB module provides 50% more capacity per slot using advanced die technology.
