NEMIX RAM

NEMIX RAM DDR5 6400 64GB (2x32GB) CL52 1.1V 2Rx4 ECC RDIMM Supermicro X14SDV-36CE-SP3F memory upgrade

SKU CH-K9H6-S94SY

64 GB DDR5 ECC registered server memory kit with two 32 GB modules at 6400 MHz CL52 1.1 V for Supermicro X14SDV-36CE-SP3F

  • 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

  • Exact DDR5-6400 64 GB kit matched to Supermicro X14SDV-36CE-SP3F for full-speed recognition
  • Registered 2Rx4 ECC RDIMM offloads the memory controller and corrects single-bit errors automatically
  • Low 1.10 V operation at CL52 reduces power draw while maintaining rated throughput
  • 288-pin RDIMM form factor fits the board's required slots without adapters
  • Built with major OEM Samsung Micron Hynix chips for enterprise-grade reliability

Exact-Match Server Upgrade

This 64 GB kit (2 x 32 GB) of DDR5-6400 ECC Registered RDIMM memory is built specifically for the Supermicro X14SDV-36CE-SP3F motherboard. It delivers the precise rank, voltage and timing the board's memory controller expects so the full capacity is recognised at rated speed.

Build Integration

The 288-pin RDIMM form factor matches the slots this board requires, not UDIMM or SODIMM alternatives. Registered architecture offloads the memory controller, allowing every populated slot to run at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Sustained Operation

Operating at 1.1 V with CL52 latency, the modules maintain rated DDR5-6400 throughput under continuous enterprise workloads. Registered buffering keeps signal integrity stable when all channels are fully populated, avoiding the throttling or errors that unbuffered designs can exhibit under prolonged load.

Questions about this item

Does the 6400 MT/s speed hold under continuous 24/7 server workloads?

The kit is rated DDR5-6400 (PC5-51200) with CL52 at 1.1 V; registered buffering and ECC are designed to maintain that data rate when all slots are populated and the system runs sustained loads.

How much heat and power do two 32 GB modules draw in a fully populated chassis?

Each module operates at 1.10 V without a heat spreader; registered architecture reduces electrical load on the memory controller, so total power and thermal output stay within standard RDIMM limits for the Supermicro X14SDV-36CE-SP3F platform.

What motherboard and firmware must I already have for this 64 GB kit to be recognised at full capacity?

The memory is validated for the Supermicro X14SDV-36CE-SP3F motherboard running DDR5-6400; the board must support 2Rx4 registered ECC RDIMMs and its BIOS must be current enough to initialise the full 64 GB (2 × 32 GB) population.
