Eight green DDR5 RDIMM modules with black chips, no heat spreaders

NEMIX RAM

NEMIX RAM 256GB (8x32GB) DDR5 4800 CL40 ECC RDIMM Server Memory Upgrade

SKU CH-RTW0-NK5MH

Adds 256 GB of DDR5 ECC registered server memory in eight 32 GB modules at 4800 MT/s CL40

  • Capacity256GB (8 x 32GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 256GB total capacity scales demanding server workloads
  • DDR5 4800MHz speed feeds data to multi-core CPUs
  • ECC registered design corrects errors for uptime
  • 1V operation reduces power draw per module
  • Validated for Supermicro 821 and 421 GPU SuperServers

Compatible SuperMicro DDR5 Servers

This 256GB kit contains eight 32GB DDR5 4800 ECC registered DIMMs built for SuperMicro GPU SuperServer systems including the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. Each module runs at 1.1V with CL40 latency and a 1Rx4 organisation. The registered design adds signal integrity for dense multi-DIMM configurations.

IT Teams Needing Validated Capacity

Departments expanding memory in the listed SuperMicro platforms can install this matched kit without mixing modules of different rank or voltage. Builders who require unbuffered UDIMMs, non-ECC memory, or speeds above 4800MT/s should select a different product line. The absence of heat spreaders also means this kit relies on chassis airflow for cooling.

1Rx4 Registered ECC Architecture

The single-rank-by-four organisation lets all eight DIMMs populate a full channel set while keeping electrical loading low enough for stable operation at the rated 4800MT/s. This rank structure is the decisive factor when the server memory controller expects 1Rx4 registered modules.

Questions about this item

Does the kit include all eight 32GB modules or must any be purchased separately?

The package contains eight 32GB modules for a total of 256GB; nothing else is required to reach that capacity.

Should I choose the CL40 1.1V version or a different latency and voltage?

This kit is specified at CL40 and 1.1V, matching the DDR5 4800 standard for the supported Supermicro servers.

What does the 4800 MT/s rating mean once the modules are installed in a Supermicro GPU SuperServer?

The memory will run at 4800 MT/s (PC5-38400) with ECC and registered operation on the compatible SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT platforms.
