NEMIX RAM 512GB 8x64GB DDR5 6400MHz CL52 1.1V 2Rx4 ECC RDIMM Supermicro SYS-222HA-TN

SKU CH-8A2Z-CTDPA

512 GB DDR5 ECC RDIMM kit of eight 64 GB modules at 6400 MHz CL52 1.1 V for Supermicro SYS-222HA-TN

  • Total capacity512 GB (8 × 64 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx4
  • 512 GB total capacity from eight 64 GB modules for high-density server workloads
  • ECC registered design detects and corrects single-bit errors to protect data integrity
  • DDR5 6400 MHz speed with CL52 latency delivers fast throughput for compute tasks
  • Low 1.1 V operating voltage reduces power draw in dense Supermicro SYS-222HA-TN deployments
  • 288-pin 2Rx4 RDIMM form factor ensures direct compatibility with the target Supermicro platform

Target server platform

This 512GB DDR5 ECC RDIMM kit is built for the Supermicro SYS-222HA-TN SuperServer. Eight registered 64GB modules provide the maximum capacity the platform supports. IT teams and data-centre operators gain reliable, high-density memory for virtualization, databases and compute clusters.

Compatibility scope

The kit suits administrators who need validated, registered ECC memory for this specific Supermicro system. Buyers requiring unbuffered UDIMM modules or non-ECC memory for workstations or consumer boards will not be able to use this kit.

Deciding specification

Registered 2Rx4 ECC RDIMM at 6400MHz CL52 and 1.10V is the single attribute that determines fit. Only systems designed for DDR5 RDIMM with this rank, voltage and latency will accept the kit.

Questions about this item

What motherboard slot type does the SYS-222HA-TN need for these 288-pin DDR5 RDIMMs?

The kit uses 288-pin DDR5 RDIMM modules, so the server must provide DDR5 RDIMM slots that accept registered ECC memory.

Can I add this 8-module kit alongside existing DDR5 RDIMMs in the SYS-222HA-TN?

Yes, provided the board has free DDR5 RDIMM slots and the installed modules are also registered ECC DDR5; mixing ranks or speeds may force the system to run at the lowest common speed.

How do I confirm the kit is running at 6400 MHz CL52 after installation?

Check the BIOS memory information or a hardware utility such as CPU-Z; it should report DDR5-6400 with CAS latency 52 and 1.1 V on all eight modules.
