Six green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM 288GB (6 x 48GB) DDR5 6400 CL52 1.1V ECC Registered RDIMM for Supermicro H14DSG-OD memory upgrade

SKU CH-29CX-6WRYS

Six 48 GB DDR5 RDIMMs totalling 288 GB at 6400 MT/s with CL52 latency, 1.1 V registered ECC for the Supermicro H14DSG-OD

  • Capacity288GB (6 x 48GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 288 GB total capacity from six 48 GB modules for dense server workloads
  • DDR5 6400 speed with CL52 latency delivers rated throughput for the H14DSG-OD
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • 10 V operation matches the board's voltage spec for stable full-population runs
  • 2Rx8 dual-rank organisation aligns with the motherboard's population rules for full recognition

Exact-Match Server Memory Kit

This 288GB kit contains six 48GB DDR5 Registered ECC RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. It is built for the Supermicro H14DSG-OD motherboard and uses the precise rank, voltage and timing that board expects. The registered architecture allows every slot to be fully populated at rated speed. Buyers who need unbuffered UDIMMs or SODIMMs cannot use this kit.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller so all six modules run at full 6400 MT/s continuously. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 1.1V JEDEC voltage keeps power draw predictable under heavy traffic. Systems that require higher voltages or non-ECC modules will not match this profile.

Pre-Installation Checklist

Confirm the motherboard manual approves 48GB 2Rx8 RDIMMs in a six-DIMM population and lists the required slot-filling order. Verify the BIOS version supports the full 288GB capacity at DDR5-6400 before installation. Ensure the chassis provides adequate airflow for modules without heat spreaders. Orders for boards with different population rules or voltage requirements will not be compatible.

Questions about this item

How much heat and power will this 1.10V DDR5 kit add when the server runs continuously?

Each module operates at 1.10 volts and the registered architecture reduces electrical load on the memory controller, keeping heat output modest even with all six slots populated at 48GB per DIMM.

What motherboard slot type and population rules must my Supermicro H14DSG-OD already have for this 288-pin RDIMM kit to work?

The board needs 288-pin DDR5 RDIMM slots and must support 2Rx8 registered modules; the kit is spec-matched to the H14DSG-OD population rules so all six DIMMs are recognised at full 288GB capacity.

Will these 6400 CL52 modules run at rated speed alongside slower DDR5 DIMMs I might keep installed?

The kit is validated for DDR5-6400 CL52 on the H14DSG-OD; mixing different speeds or timings forces the memory controller to down-clock all channels to the slowest module present.
