Two green DDR5 RDIMM modules with black chips no heat spreaders

NEMIX RAM

NEMIX RAM 128GB 2x64GB DDR5 6400 CL52 1.1V 4Rx4 ECC RDIMM for Supermicro X14SDV-36CE-SP3F memory upgrade

SKU CH-XRDX-V80PS

A 128 GB DDR5 ECC registered DIMM kit (2 × 64 GB) running at 6400 MT/s with CL52 latency and 1.1 V, validated for the Supermicro X14SDV-36CE-SP3F motherboard

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

Size 128GB 2X64GB

  • 128 GB capacity in a 2×64 GB kit supports dense server workloads
  • DDR5-6400 PC5-51200 speed matches the board's rated memory frequency
  • CL52 latency at 1.1 V delivers rated timing without over-volting
  • 4Rx4 registered ECC RDIMM architecture enables full-slot population with error correction
  • 288-pin form factor fits the Supermicro X14SDV-36CE-SP3F memory slots exactly

Exact-match DDR5-6400 ECC RDIMM kit

This 128GB kit contains two 64GB DDR5 6400 CL52 1.1V 4Rx4 Registered ECC RDIMMs built to the Supermicro X14SDV-36CE-SP3F motherboard specification. Major OEM Samsung, Micron or Hynix chips are used. The modules are 288-pin Registered DIMMs with no heat spreader.

Suited for capacity-bound servers

Administrators who need the full 128GB registered ECC population this board accepts will match rank, voltage and timing exactly. Buyers who want non-ECC UDIMMs, SODIMMs, lower capacities or speeds other than 6400 should look elsewhere.

Fills every supported slot at rated speed

The registered architecture offloads the memory controller so all populated slots run at 6400 MT/s with ECC active. No heat spreader means standard server airflow clears the modules. Verify the motherboard manual for approved population order before installation.

Questions about this item

Will this 128GB DDR5 6400 kit install directly into the Supermicro X14SDV-36CE-SP3F motherboard?

Yes, the 288-pin RDIMM form factor and DDR5 6400 specification match the board's memory slots and rated speed exactly.

Can I mix these 4Rx4 registered ECC modules with older DDR5 RDIMMs of different rank or speed in the same server?

Mixing ranks or speeds is not recommended; the memory controller will down-clock all channels to the slowest module and may limit total capacity per channel.

How can I confirm the kit is running at DDR5 6400 CL52 1.1V with ECC active after installation?

Enter the BIOS or use a tool like dmidecode to verify each DIMM shows 6400 MT/s, CL52 timings, 1.1V, registered type, and ECC enabled.
