  • 64 GB capacity lets you run large workloads in fewer slots
  • DDR5 5600 speed transfers data at the rated PC5-44800 bandwidth
  • Registered ECC design corrects single-bit errors and offloads the memory controller
  • 1 V operation matches the motherboard voltage requirement for stable full-population use
  • 288-pin RDIMM form factor fits the Supermicro H14DSG-O-CPU slot exactly

Exact-Match 64 GB DDR5-5600 RDIMM

This 64 GB DDR5-5600 module delivers the precise rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. Registered ECC architecture with CL46 latency and 1.1 V operation ensures the module is recognised at full capacity and runs at its rated PC5-44800 speed. It targets administrators upgrading that specific server platform with validated components.

288-Pin Registered Form Factor for Full Population

The 288-pin RDIMM form factor matches the board's physical and electrical requirements, not a UDIMM or SODIMM. Registered buffering offloads the memory controller so every slot can be fully populated at the rated capacity and speed. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production workloads.

Sustained Enterprise Stability Under Load

Registered architecture and ECC combine to maintain data integrity when all channels run continuously at 5600 MT/s. The module operates at the standard 1.1 V without requiring elevated voltage headroom. Builders who need a different capacity, an unbuffered DIMM, or a non-ECC variant should select an alternative product matched to those requirements.

Questions about this item

What sustained-load limit appears first with the 1.10V DDR5 5600 CL46 modules fully populated?

The 1.10V operating voltage is the first fixed limit; the registered ECC RDIMM architecture lets every slot run at the rated 5600 MT/s without down-clocking, so voltage headroom, not bandwidth, becomes the binding constraint.

How much heat and power do the 64GB 2Rx4 RDIMMs add when the server runs all day?

Each module draws 1.10V at DDR5 5600 speeds with no heat spreader; registered buffering keeps per-DIMM power low, so total thermal load scales linearly with the number of populated slots.

Which motherboard feature must already be present for these 288-pin RDIMMs to work?

The Supermicro H14DSG-O-CPU must provide DDR5 RDIMM slots with registered-ECC support and the correct population rules; the modules are keyed for 288-pin DDR5 and will not fit UDIMM or SODIMM sockets.
