Six green DDR4 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM DDR4 ECC RDIMM Registered Server Memory 768GB (6 x 128GB) 3200MHz CL22 1.2V 288-Pin

SKU CH-86JS-BJZD7

A 768GB registered ECC DDR4 server kit of six 128GB modules running at 3200MHz CL22 and 1.2V on 288 pins

  • Capacity768GB (6 x 128GB)
  • Type288-Pin DDR4 RDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.20V
  • ECCYes

Capacity 768GB (6 x 128GB)

  • Massive 768 GB capacity across six 128 GB modules
  • ECC registered design protects data integrity in servers
  • DDR4 3200 speed at CL22 latency for responsive throughput
  • Low 1.2 V operation reduces power draw per module
  • Built with major OEM chips and stress-tested for reliability

768GB DDR4 ECC RDIMM kit

This 768GB kit contains six 128GB DDR4 3200 registered DIMMs with ECC and a CAS latency of 22. It is built for servers and workstations that require registered memory and error correction for data integrity. The modules operate at 1.2V using major OEM DRAM from Samsung, Micron or Hynix. Systems that only accept unbuffered UDIMMs or non-ECC memory cannot use this kit.

Sustained load stability

All modules are rigorously stress tested under load to ensure reliability during continuous operation. Registered buffering and ECC maintain signal integrity and correct single-bit errors across the full 768GB capacity at DDR4 3200 speeds. The 1.2V operating voltage supports consistent thermal behaviour in dense multi-DIMM configurations. Workloads that exceed the registered memory limit of the platform will not benefit from this capacity.

Installation and common issues

The 288-pin RDIMM form factor installs in standard DDR4 server slots following the motherboard population rules for 4Rx4 modules. Compatibility depends on the platform supporting registered ECC memory and the total capacity per channel. Mixing these modules with unbuffered or different-rank DIMMs will prevent boot or reduce stability. Always consult the system manual for the correct slot order and maximum supported density.

Questions about this item

How much power does the 1.2 V DDR4 3200 kit draw when running 768 GB continuously?

Each module operates at 1.20 V; total draw depends on your platform's memory controller and workload, not on the kit alone.

What motherboard feature is required to use these 288-pin 4Rx4 registered DIMMs?

The board must support DDR4 RDIMM ECC memory with 4Rx4 organisation and 288-pin slots.

Will these CL22 registered modules work alongside older DDR4 UDIMMs I already own?

No — registered and unbuffered DIMMs cannot be mixed on the same motherboard.
