Four green DDR5 RDIMM modules in static bags

NEMIX RAM

NEMIX RAM MR51200-924K4 256GB DDR5 6400 ECC RDIMM 4x64GB memory upgrade

SKU CH-1S9J-S24AF

A 256 GB DDR5 ECC registered memory kit with four 64 GB modules running at 6400 MHz, CL52 and 1.1 V for the ASRock Rack TURIN2D24XGM/500W motherboard

  • Capacity256GB (4 x 64GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 256GB 4X64GB

  • 256 GB total capacity across four 64 GB modules for maximum density
  • DDR5 6400 (PC5-51200) speed with CL52 latency at 1.10 V for rated performance
  • Registered ECC RDIMM architecture corrects single-bit errors and buffers signals for stability
  • 2Rx4 dual-rank organisation enables full population on supported ASRock Rack boards
  • 288-pin DDR5 RDIMM form factor matches the TURIN2D24XGM/500W motherboard slot requirement

Exact-match server upgrade

This 256GB kit delivers four 64GB DDR5 6400 RDIMM modules built to the precise rank, voltage and timing the ASRock Rack TURIN2D24XGM/500W memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly, so fully populated slots run at rated speed without silent data corruption.

For fully populated enterprise boards

Suited for administrators populating every DIMM slot on the validated motherboard with registered ECC memory that meets the board's population rules. Not for systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC modules or lower-density kits that the platform cannot address at full capacity.

Sustained-load stability

Registered buffering keeps electrical loading constant across all channels during continuous workloads, while on-die ECC corrects errors in real time so throughput remains consistent over long runs. The 1.1V operating voltage and CL52 latency are maintained without throttling when the kit is installed per the motherboard's population guide.

商品問答

Do I need an ASRock Rack TURIN2D24XGM/500W motherboard to use this 256GB DDR5 6400 ECC RDIMM kit?

Yes, this 4 x 64 GB kit is validated for that specific motherboard. The board must support DDR5 6400 RDIMM memory, registered ECC operation, and 2Rx4 rank configuration at 1.1 V.

Can I mix these 2Rx4 DDR5 6400 RDIMMs with existing 1Rx4 modules on the same motherboard?

Mixing different rank organisations on the same channel is not recommended; the memory controller will default to the lowest common speed and may limit total capacity.

How do I confirm the kit runs at DDR5 6400 CL52 after installation?

Enter the BIOS and verify the memory frequency shows 6400 MT/s with CL52 timings; the POST screen should also report the full 256 GB as registered ECC.
