Two green DDR5 RDIMM modules without heat spreaders, 288-pin, 64GB kit

NEMIX RAM

NEMIX RAM 64GB (2x32GB) DDR5 6400 CL52 1.1V 2Rx4 ECC RDIMM Supermicro X14SDW-42C-SP9F memory upgrade

SKU CH-GSXC-1ZXY6

A 64 GB DDR5 ECC registered DIMM kit, two 32 GB modules at 6400 MT/s CL52 1.1 V 2Rx4, validated for the Supermicro X14SDW-42C-SP9F motherboard

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 64GB 2X32GB

  • 64 GB capacity from two 32 GB modules for full server memory expansion
  • DDR5 6400 speed with CL52 latency delivers rated throughput on Supermicro X14SDW-42C-SP9F
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors automatically
  • 10 V operation at 2Rx4 rank matches the board's memory-controller requirements exactly
  • 288-pin RDIMM form factor fits the motherboard's DDR5 slots without adapters or mismatches

Exact-fit DDR5-6400 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5-6400 registered ECC modules rated at CL52 and 1.10V. The 288-pin RDIMM form factor matches the Supermicro X14SDW-42C-SP9F motherboard's requirements for registered memory with 2Rx4 organisation.

Suited for populating the validated Supermicro

Builders expanding the named Supermicro board to its supported capacity with registered ECC modules will find the rank, voltage and timing pre-matched. Those needing unbuffered UDIMMs, SODIMMs, non-ECC memory or a different DDR generation should look elsewhere.

Drops into the board's 288-pin RDIMM slots

Registered architecture reduces electrical load on the memory controller when all slots are filled, while on-die ECC corrects single-bit errors without software intervention. The kit frees you from verifying individual timing parameters because the SPD profile matches the platform's qualified speed of DDR5-6400.

Questions about this item

Does the Supermicro X14SDW-42C-SP9F motherboard need any specific BIOS setting to recognise the 64GB 2Rx4 RDIMM kit at 6400 speed?

The kit is an exact-match upgrade for the X14SDW-42C-SP9F, so the board's memory controller expects the 2Rx4 rank, 1.10V voltage and CL52 timing; it will be recognised at full capacity and rated speed without extra configuration.

Can I keep my existing DDR5 RDIMMs installed while adding this 64GB kit to the same board?

The X14SDW-42C-SP9F follows its own population rules; you must consult the motherboard manual for supported capacities and approved DIMM order before mixing this 2Rx4 kit with other modules.

How do I confirm the new memory is running at 6400 MT/s with ECC active after installation?

Enter the system BIOS or use a hardware-info utility in the OS; both will report the DDR5 6400 (PC5-51200) data rate, CL52 latency, 1.10V voltage and Registered ECC status for each 32GB module.
