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

NEMIX RAM

NEMIX RAM 64GB (2x32GB) DDR5 6400 CL52 2Rx4 ECC Registered RDIMM for Supermicro X14SDV-42C-SP3F memory upgrade

SKU CH-4F16-JDW3Q

A 64 GB DDR5-6400 registered ECC kit (2 × 32 GB, CL52, 1.1 V, 2Rx4) built to the exact specifications of the Supermicro X14SDV-42C-SP3F motherboard

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

Size 64GB 2X32GB

  • 64 GB capacity with two 32 GB modules for full server memory population
  • DDR5 6400 speed with CL52 latency at 1.10 V for rated performance
  • Registered ECC RDIMM architecture corrects single-bit errors and offloads the memory controller
  • 288-pin 2Rx4 form factor matches Supermicro X14SDV-42C-SP3F slot requirements
  • Major OEM Samsung Micron Hynix chips provide enterprise-grade component reliability

64GB DDR5 6400 Registered ECC Kit

This 64GB kit contains two 32GB DDR5 6400 RDIMMs built for the Supermicro X14SDV-42C-SP3F motherboard. Each module runs at CL52 latency and 1.10V as a 2Rx4 Registered ECC device. The 288-pin form factor matches the board's DDR5 slots exactly so the memory controller recognises the full capacity at rated speed. It targets administrators who need validated server memory for this specific platform.

Registered DDR5 Interface Limits

Registered DDR5 architecture buffers address and command signals so the memory controller can drive every populated slot at the rated 6400 MT/s data rate. ECC circuitry corrects single-bit errors on the fly to prevent silent data corruption. The modules require a motherboard wired for 288-pin RDIMMs; they will not fit UDIMM or SODIMM slots and they cannot operate on platforms that only support unbuffered memory.

64GB Capacity and Headroom

The 64GB total delivered by two 32GB ranks provides ample space for typical virtualisation hosts, database buffers and container workloads on this board. Population rules for the X14SDV-42C-SP3F determine how many additional kits can be added before the controller reaches its maximum supported capacity. Workloads that demand more memory than the board's validated limit will require a different platform rather than larger modules of this specification.

Questions about this item

Should I choose the 64GB 2x32GB kit or a different capacity for my Supermicro X14SDV-42C-SP3F?

This 64GB kit provides two 32GB DDR5 6400 RDIMMs. Check your motherboard manual for the supported capacity per slot and the total memory limit before deciding.

What does DDR5 6400 mean for actual throughput in the X14SDV-42C-SP3F?

The modules run at 6400 MT/s, delivering PC5-51200 bandwidth when the memory controller is configured for that speed and all slots are populated with registered DIMMs.

Does the 288-pin RDIMM interface limit how many modules I can install?

The 288-pin registered form factor is required by the X14SDV-42C-SP3F; the board's memory-population rules determine the maximum number of modules and the installation order.
