Eight green DDR5 RDIMM modules with black chips no heat spreaders

NEMIX RAM

NEMIX RAM 512GB 8x64GB DDR5 6400 CL52 2Rx4 1.1V ECC Registered RDIMM Supermicro H13DSH memory upgrade

SKU CH-GFAH-7F6JG

Eight 64 GB DDR5 RDIMM modules deliver 512 GB of registered ECC memory at 6400 MT/s, CL52, 1.1 V for Supermicro H13DSH servers

  • Total capacity512 GB (8 × 64 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 512GB total capacity lets you fully populate the Supermicro H13DSH with eight 64GB modules
  • DDR5 6400 speed with CL52 latency runs at the board's rated frequency without down-clocking
  • Registered ECC architecture corrects single-bit errors on the fly to prevent silent data corruption
  • 2Rx4 dual-rank organization matches the motherboard's memory-controller expectations for stable operation
  • 1V standard voltage keeps power draw within the platform's design envelope

Server memory upgrade

This 512GB kit contains eight 64GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. It is built for administrators who need maximum registered ECC capacity on a Supermicro H13DSH motherboard.

Build integration

The 288-pin registered form factor matches the board's DIMM slots and population rules, so every channel can be filled without signal-loading issues. ECC and registered buffering let the memory controller manage the full 512GB at rated speed while correcting single-bit errors before they reach applications.

Thermals and power

Modules run at the standard 1.1V DDR5 voltage and have no heat spreaders, relying on chassis airflow for cooling. Registered architecture reduces electrical load on the memory controller, keeping power draw predictable across all eight slots during sustained server workloads.

Questions about this item

What is the CAS latency limit that appears first under sustained load?

The modules run at CL52, which is the rated timing the memory controller expects for stable operation at DDR5-6400.

How much power and heat do the eight RDIMMs draw when the server runs all day?

Each module operates at 1.1 V; with no heat spreaders the registered design offloads the controller so fully populated slots stay within standard DDR5 thermal limits.

Which motherboard and DIMM population rules must already be in place for this kit to work?

The kit is validated for the Supermicro H13DSH motherboard and requires its 288-pin RDIMM slots populated in the board's approved order.
