  • 128 GB total capacity across four 32 GB modules for dense server deployments
  • DDR5 5600 speed rated at PC5-44800 for high-throughput workloads
  • Registered ECC design with 2Rx8 organisation offloads the controller and corrects single-bit errors
  • CL46 latency at 1.1 V delivers stable operation within JEDEC limits
  • Validated for Supermicro X14SDW-64C-SP9F motherboard ensuring correct population and full-speed recognition

Exact-match server upgrade

This 128GB kit contains four 32GB DDR5 RDIMMs rated at 5600MT/s with CL46 latency and 1.1V operation. It targets administrators who need the precise rank, voltage and timing the Supermicro X14SDW-64C-SP9F memory controller expects for full-capacity recognition.

Sustained-load behaviour

Registered architecture buffers every command so all slots remain stable when fully populated under continuous workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended production runs.

Build and daily implications

Modules ship without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor fits only registered DIMM slots, not UDIMM or SODIMM sockets, so installation must follow the motherboard's documented population order.

Questions about this item

How much power does this 1.1 V DDR5-5600 kit draw when the server runs all day?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 128 GB capacity and 5600 MT/s data rate your workload demands.

What must my motherboard provide for these four 288-pin RDIMMs to function?

A DDR5 RDIMM slot that supports 2Rx8 registered ECC modules at 5600 MT/s (PC5-44800) and accepts the 1.10 V operating voltage.

Can I mix this 2Rx8 registered ECC kit with other DDR5 RDIMMs already installed in the same Supermicro X14SDW-64C-SP9F board?

The board's memory-population rules decide; matching rank, voltage and speed (5600 MT/s CL46) gives the best chance of stable operation.
