NEMIX RAM

NEMIX RAM 64GB DDR4 2933MHz CL21 2Rx4 1.2V 288-pin ECC RDIMM memory upgrade

SKU CH-RDM5-AMQEX

Adds 64 GB of DDR4-2933 ECC registered memory with CL21 latency for Lenovo ThinkSystem servers

  • Capacity64GB
  • SpeedDDR4 2933 (PC4 23400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • 64GB capacity supports heavy server workloads
  • DDR4 2933MHz speed enables fast data throughput
  • CL21 latency provides responsive memory access
  • ECC registered design protects data integrity
  • 2V operation reduces power consumption

Capacity and Form Factor

This is a single 64GB DDR4 2933MHz ECC registered DIMM built on a 288-pin RDIMM PCB. It operates at 1.2V with CL21 latency and uses a 2Rx4 rank configuration for server and workstation platforms.

Who This Suits

IT professionals upgrading Lenovo ThinkSystem servers that require PC4-23400 registered ECC memory will find this module validated for that environment. Builders needing unbuffered UDIMM memory, non-ECC modules, or speeds other than 2933MHz should look at a different product.

Build Integration

The stick plugs directly into a compatible 288-pin DDR4 RDIMM slot and draws standard 1.2V power without a heat spreader. It frees the remaining memory channels for additional registered ECC modules of matching specification.

Puntos fuertes

  • 64GB capacity supports heavy server workloads
  • DDR4 2933MHz speed enables fast data throughput
  • CL21 latency provides responsive memory access
  • ECC registered design protects data integrity
  • 2V operation reduces power consumption

Preguntas sobre este artículo

Does this 288-pin DDR4 RDIMM fit a Lenovo ThinkSystem that specifies part number 4X77A12186?

Yes, the module is built to match the 4X77A12186 specification for Intel-based ThinkSystem servers.

Will the 1.2 V registered ECC design work in a slot that currently holds 1.2 V registered ECC memory?

The 1.20 V registered ECC electrical profile matches the existing 1.2 V registered ECC DIMMs, so the server will train them together.

How can I confirm the 64 GB stick is recognised at 2933 MHz with CL21 timings after installation?

Check the BIOS memory information or OS tool such as dmidecode — it should show 64 GB, 2933 MT/s, CL21, 2Rx4 organisation and ECC enabled.
