NEMIX RAM

NEMIX RAM 64GB DDR5 6400MHz CL52 2Rx4 1.1V ECC RDIMM memory upgrade

SKU CH-6D6Q-V0Z1W

64 GB DDR5 ECC registered server module at 6400 MHz CL52, 2Rx4, 1.1 V for Supermicro SYS-822GS-NB3RT

  • Total capacity64 GB
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx4
  • 64GB capacity expands server memory headroom for virtualisation workloads
  • DDR5 6400MHz speed delivers high bandwidth for data-intensive applications
  • ECC registered design detects and corrects memory errors automatically
  • 1V operating voltage reduces power draw in dense configurations
  • Validated for Supermicro SuperServer SYS-822GS-NB3RT compatibility

Capacity and Form Factor

This 64GB DDR5 module uses the 288-pin RDIMM form factor and operates at 6400MHz with a CL52 latency. It is built with major OEM chips from Samsung, Micron or Hynix and runs at 1.10V. The registered design includes ECC for data integrity in server environments.

Target Server Builders

The module is validated for the Supermicro SuperServer SYS-822GS-NB3RT platform. It suits administrators upgrading that specific system or compatible Supermicro boards requiring registered ECC memory. It is not for desktop PCs, laptops or workstations that accept only unbuffered non-ECC DIMMs.

Workload Headroom

The single 64GB rank configuration provides substantial capacity for virtualisation, database caching and memory-intensive compute tasks. The 6400MHz speed delivers high throughput for supported workloads. Systems needing more than 64GB per slot or lower latency timings should evaluate alternative modules.

Questions about this item

Will this 288-pin DDR5 RDIMM fit a Supermicro SYS-822GS-NB3RT server?

The module is listed as compatible with the Supermicro SuperServer SYS-822GS-NB3RT, so the 288-pin DDR5 RDIMM form factor matches that system's memory slots.

Can I add this ECC RDIMM alongside existing registered DDR5 modules in the same server?

Yes, the registered ECC design allows it to operate with other registered DDR5 DIMMs, provided the motherboard supports mixed capacities and the total population rules are followed.

How do I confirm the 64GB CL52 module is running at 6400MHz after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify the reported speed shows 6400MHz and the CAS latency reads CL52 for the installed DIMM.
