Twelve green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 768GB (12x64GB) DDR5 4800 CL40 2Rx4 ECC RDIMM Server Memory Upgrade

SKU CH-8RJ7-8AD27

A 768 GB DDR5 registered ECC server kit of twelve 64 GB modules running at 4800 MT/s CL40 1.10 V for Supermicro GPU SuperServer systems

  • Capacity768GB (12 x 64GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 768 GB total capacity for memory-intensive server workloads
  • 12 modules of 64 GB each simplify large-scale deployment
  • DDR5 4800 speed with CL40 latency supports high-throughput computing
  • ECC registered RDIMM design protects data integrity in critical systems
  • 1 V operating voltage reduces power draw per module

System-specific DDR5 kit

This 768GB kit contains twelve 64GB DDR5 4800 ECC RDIMM modules built for Supermicro GPU SuperServer platforms including the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. It targets administrators who need maximum registered memory capacity in those qualified systems.

Upgrade from lower-density RDIMMs

Replacing smaller RDIMM modules with this 12-module set fills every slot to reach the platform's 768GB ceiling. The jump is worth it when workloads such as large-scale virtualization or in-memory databases exceed the capacity of a partially populated configuration.

Capacity and headroom

Twelve dual-rank 2Rx4 modules at 1.10V deliver 768GB of registered ECC memory with CL40 latency across a 288-pin interface. The kit handles memory-intensive server tasks until the CPU or memory-controller limit is reached, at which point additional capacity cannot be added without a platform change.

Preguntas sobre este artículo

Will these 288-pin DDR5 RDIMM modules fit the memory slots on a SuperMicro SYS-821GE-TNHR server?

Yes, the kit is listed as compatible with SuperMicro GPU SuperServer SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT systems.

What is the correct way to populate all 12 modules, and which step is often missed?

Follow the motherboard manual for the exact slot population order; the step often missed is ensuring each module clicks fully into the 288-pin socket so the retention clips lock.

If a module fails years later, what replacement does the kit’s lifetime warranty cover?

The lifetime replacement warranty covers a matching 64 GB DDR5 4800 CL40 2Rx4 ECC RDIMM module from the same series.
