Two green DDR5 ECC RDIMM modules with black chips, no heat spreader

NEMIX RAM

NEMIX RAM 64GB (2x32GB) DDR5 6400MHz CL52 2Rx8 1.1V 288-Pin ECC RDIMM memory upgrade

SKU CH-YSFB-K70FH

A 64GB DDR5 registered ECC kit with two 32GB modules at 6400MHz CL52 for Supermicro servers

  • Total capacity64 GB (2 × 32 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx8
  • 64 GB total capacity in a matched 2 x 32 GB kit
  • DDR5 6400 MHz speed with CL52 latency for responsive server workloads
  • ECC registered RDIMM design detects and corrects single-bit errors automatically
  • Low 1.10 V operating voltage reduces power draw in dense configurations
  • Validated for Supermicro GPU SuperServer SYS-422GS-NBRT-LCC systems

Capacity and purpose

This kit provides 64GB of DDR5 ECC registered memory in two 32GB modules. It is intended for servers and workstations that require error-correcting registered DIMMs for data integrity. Builders needing unbuffered consumer DIMMs or non-ECC memory should look elsewhere.

Sustained-load behaviour

The modules run at 6400MHz with a CAS latency of 52 at 1.1V. Registered buffering and ECC allow the memory controller to maintain signal quality and correct single-bit errors during continuous workloads. The 2Rx8 organisation supports stable throughput in multi-channel server configurations.

Pre-order checks

Verify that your motherboard accepts 288-pin DDR5 RDIMMs and supports registered ECC operation. Confirm the platform can operate memory at 6400MHz and 1.1V without manual tuning. Ensure the system in question is the Supermicro GPU SuperServer SYS-422GS-NBRT-LCC or another board qualified for this exact part number.

Questions about this item

How much power do the 1.10V modules draw under sustained load?

Each stick is rated at 1.10V, the standard DDR5 operating voltage, so power draw scales with the 6400MHz data rate and the registered buffer on the DIMM.

What motherboard feature must already be present for this ECC RDIMM kit to function?

The board needs DDR5 RDIMM slots that support registered ECC memory and a memory controller able to address 2Rx8 organisation.

Will the 288-pin DDR5 RDIMM form factor fit in a Supermicro SYS-422GS-NBRT-LCC alongside existing DDR5 RDIMMs?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor and 2Rx8 rank layout, so it installs in any compatible DDR5 RDIMM slot on that platform.
