Frequently Asked Questions

What is the difference between DDR5 RDIMM and DDR4 RDIMM?

DDR5 RDIMMs operate at higher speeds (4800MHz+), lower voltage (1.1V vs 1.2V), and include native on-die ECC. DDR5 and DDR4 are not interchangeable — DDR5 requires a DDR5-capable server platform.

Is HMCG94AGBRA182N compatible with Intel Xeon Sapphire Rapids?

Yes, it is compatible with Intel Xeon Scalable Sapphire Rapids server platforms supporting DDR5-5600 ECC RDIMM. Verify your specific server's QVL before ordering.

What is the difference between HMCG94AGBRA182N (DDR5-5600) and HMCG94MEBRA123N (DDR5-4800)?

Both are SK Hynix 64GB DDR5 ECC RDIMM 2Rx4 modules. HMCG94AGBRA182N runs at DDR5-5600MHz (PC5-44800) while HMCG94MEBRA123N runs at DDR5-4800MHz (PC5-38400) — they are different speed grades.
