NEMIX RAM 128GB DDR4 3200 4Rx4 ECC RDIMM Supermicro memory upgrade

SKU CH-FWHE-181Y5

A single 128 GB DDR4 3200 registered ECC module built for Supermicro servers

  • Total capacity128 GB
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • 128 GB capacity expands server memory headroom for large workloads
  • DDR4 3200 speed delivers high bandwidth for data-intensive applications
  • ECC registered design detects and corrects errors to protect data integrity
  • 4Rx4 organisation maximises density within a single 288-pin module
  • 2 V operation reduces power draw in dense Supermicro configurations

128GB DDR4 3200 ECC RDIMM

This 128GB DDR4 3200 registered DIMM adds ECC-protected capacity to compatible Supermicro servers and workstations. It operates at 1.2V with CL22 latency and a 4Rx4 organisation. The module uses major-brand Samsung, Micron or Hynix chips and carries part number MR25600-744K1.

Replaces lower-capacity RDIMMs

Swapping smaller registered modules for this single 128GB stick raises total memory without occupying additional slots. The upgrade is worthwhile when workloads exceed the current limit and the platform supports 4Rx4 registered DIMMs at 3200MT/s.

Fits Supermicro DDR4 RDIMM slots

The 288-pin form factor installs directly into registered DDR4 channels on supported Supermicro motherboards. ECC and register logic maintain signal integrity at high density, freeing remaining slots for future expansion. No heat spreader is included.

Questions about this item

Does the 288-pin DDR4 RDIMM fit my Supermicro server DIMM slots?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor that matches Supermicro server DIMM slots.

How do I install the 128GB 4Rx4 module, and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify the 3200 MT/s speed and CL22 timing in BIOS.

When will the ECC registered memory need replacement?

The module has no heat spreader and runs at 1.20 V; with proper airflow it typically lasts the server's service life, and the vendor provides a lifetime replacement warranty.
