Two green DDR5 RDIMM modules without heat spreaders, 288-pin, 128GB kit

NEMIX RAM

NEMIX RAM MR51200-924K2 128GB (2x64GB) DDR5 6400 ECC RDIMM memory upgrade

SKU CH-8EZN-CYJMR

128 GB DDR5-6400 ECC registered DIMM kit (2×64 GB, 2Rx4, CL52, 1.1 V) validated for the ASRock Rack TURIN2D24XGM/500W motherboard

  • Capacity128GB (2 x 64GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 128GB 2X64GB

  • 128 GB capacity from two 64 GB modules for dense server memory
  • DDR5 6400 speed with CL52 latency matches the board's rated timing
  • Registered ECC architecture offloads the controller and corrects single-bit errors
  • 10 V operation at the exact voltage the memory controller expects
  • 288-pin RDIMM form factor fits the ASRock Rack TURIN2D24XGM/500W motherboard

Targeted server upgrade

This 128GB kit provides two 64GB DDR5 6400 ECC Registered DIMMs built for the ASRock Rack TURIN2D24XGM/500W motherboard. It matches the board's required 288-pin RDIMM form factor, 2Rx4 rank structure, 1.10V operating voltage and CL52 latency so the memory controller recognises full capacity at rated speed.

Platform-specific limits

The modules operate only with systems that accept DDR5 6400 (PC5-51200) Registered ECC memory and follow the motherboard's validated population rules. Mixing with unbuffered UDIMMs, SODIMMs or different rank configurations will prevent boot or reduce stability, so the host platform must explicitly support this exact specification.

Daily handling implications

Chips from major OEM suppliers (Samsung, Micron, Hynix) are mounted on bare green PCBs without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM keying prevents accidental insertion into incompatible slots, while registered buffering ensures electrical stability when all channels are fully populated in dense rack deployments.

Perguntas sobre este artigo

Should I choose the 128GB 2x64GB kit or a different capacity for my ASRock Rack TURIN2D24XGM/500W motherboard?

This 128GB kit provides two 64GB DDR5 6400 RDIMMs. Check your motherboard manual for the maximum supported capacity per slot and the approved population order before deciding.

What does the DDR5 6400 speed rating mean once the modules are installed in the server?

The modules will run at 6400 MT/s with CL52 latency at 1.1V, delivering PC5-51200 bandwidth, provided the motherboard memory controller supports that speed with a fully populated 2Rx4 configuration.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The 288-pin RDIMM form factor fits the board's DDR5 slots. Registered buffering reduces electrical load on the memory controller, and ECC corrects single-bit errors to prevent data corruption.
