Size 64GB 2X32GB

  • 64 GB capacity across two 32 GB modules expands server memory headroom for virtualization workloads
  • DDR5 6400 speed with CL52 latency delivers rated throughput for Supermicro X14SDV-36C-SP3F platforms
  • Registered ECC architecture corrects single-bit errors on the fly to prevent silent data corruption
  • 10 V operation at 2Rx4 rank matches the memory controller's exact voltage and timing requirements
  • 288-pin RDIMM form factor fits the motherboard's registered DIMM slots without adapter or modification

Capacity and purpose

This 64 GB kit contains two 32 GB DDR5 6400 RDIMM modules built for the Supermicro X14SDV-36C-SP3F motherboard. The registered ECC design targets servers and workstations that require error correction and full-slot population at rated speed.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so all populated slots operate at DDR5 6400 without downclocking. ECC corrects single-bit errors in real time, preventing silent data corruption during continuous workloads.

Pre-installation checks

Verify the motherboard manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before installation. This kit uses 288-pin RDIMM form factor and 1.1 V operation; it is not compatible with UDIMM or SODIMM slots.

Questions about this item

How much power does this 1.1 V DDR5 6400 kit draw when the Supermicro X14SDV-36C-SP3F runs fully populated all day?

Each module operates at 1.10 V, the standard DDR5 voltage, so total draw scales with the 64 GB capacity and 2Rx4 registered design; the board's memory controller manages power per slot.

What must the Supermicro X14SDV-36C-SP3F already have to accept this 288-pin RDIMM kit?

The motherboard needs DDR5 RDIMM slots wired for registered ECC memory and a CPU memory controller that supports DDR5 6400 at 1.1 V with 2Rx4 population rules.

Can I keep existing DDR5 RDIMMs in the other channels while adding this 2Rx4 CL52 kit?

Yes, provided the other modules are also DDR5 registered ECC at 1.1 V; the board will train all channels to the lowest common speed and latency.
