128GB DDR5-4800 ECC RDIMM Server Module

This 128GB DDR5-4800 registered ECC module targets server and workstation operators who need high-density memory for virtualisation, database or compute workloads. The 4Rx4 3DS organisation packs four ranks into a single 288-pin DIMM, maximising capacity per slot. Major-brand DRAM ICs and factory testing aim to deliver dependable operation in qualified platforms.

Check DDR5 RDIMM Support and Slot Population Rules

Before ordering, confirm that your motherboard or server chassis accepts DDR5 registered DIMMs and that the memory controller supports 4Rx4 modules at the desired speed. Consult the vendor manual for approved population sequences, maximum modules per channel and any BIOS version requirements, because unsupported rank configurations can prevent boot or reduce performance.

Replaces Hynix HMCT04MEERA131N

This module serves as a direct replacement for Hynix HMCT04MEERA131N, HMCT04AEERA and HMCT04AEERA131N parts. The upgrade is worthwhile when your qualified system documentation lists these part numbers and you need to expand memory capacity or replace a failed unit without changing the platform.

Preguntas sobre este artículo

Does the 128GB DDR5 4800 ECC RDIMM come as a single module or a kit?

The product is a single 128GB module (1x 128GB) in a 288-pin DDR5 RDIMM form factor. No additional modules are included.

How does the 4Rx4 rank configuration affect capacity planning?

Each module provides four logical ranks (4Rx4) using 3DS/TSV stacking, so one 128GB stick delivers the density that would otherwise require multiple lower-rank modules.

What does the 4800MHz speed mean for actual server throughput?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, delivering the standard JEDEC data rate for DDR5-4800 registered ECC server memory.
