Size 64GB 2X32GB

  • 64 GB capacity in a 2 × 32 GB kit for high-density server workloads
  • DDR5 6400 speed rated at PC5-51200 for maximum throughput
  • CL52 CAS latency and 1.1 V voltage tuned for stable registered operation

  • 288-pin RDIMM form factor validated for the Supermicro X14SDV-32C-SP3F motherboard

Targeted Server Upgrade

This 64GB kit delivers two 32GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. It is built for administrators upgrading a Supermicro X14SDV-32C-SP3F motherboard that requires registered ECC memory in a 288-pin form factor.

Build Integration

The modules use a registered (buffered) architecture that reduces electrical load on the memory controller, allowing full population of every slot at the rated 6400 speed. ECC functionality detects and corrects single-bit errors in real time, protecting data integrity without additional software or configuration steps.

Upgrade Context

The kit replaces lower-capacity DDR5 RDIMMs or mixed-rank configurations that limit total memory or force downclocking. The jump is worthwhile when workloads demand the full 64GB at native 6400 MT/s with verified 2Rx4 rank structure and 1.1V compatibility. Builders needing UDIMM, SODIMM or non-ECC modules cannot use this product.

Questions about this item

Will the DDR5 6400 CL52 timing hold under continuous full-load operation?

The modules are rated DDR5 6400 with CL52 latency at 1.1 V; registered ECC buffering keeps every slot stable at that speed when fully populated.

How much heat and power should I expect from this kit running 24/7 in a server chassis?

Each 32 GB RDIMM operates at 1.10 V without a heat spreader; registered buffering reduces electrical load on the memory controller, helping thermals in dense configurations.

Does my Supermicro X14SDV-32C-SP3F motherboard need a specific BIOS version or CPU to recognise this 64 GB kit?

The kit is validated for the X14SDV-32C-SP3F at DDR5 6400; consult the board manual for approved DIMM population order and any BIOS updates required for full capacity.
