  • 256 GB total capacity from four 64 GB modules
  • DDR5 5600 speed with CL46 latency for rated throughput
  • Registered ECC design offloads the controller and corrects single-bit errors
  • 2Rx4 organisation at 1.1 V matches the Supermicro X14SDW-72C-SP9F spec
  • 288-pin RDIMM form factor fits the board's DDR5 slots

Exact-match server kit

This 256GB kit contains four 64GB DDR5 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro X14SDW-72C-SP9F motherboard expects. Each module runs at 5600MHz PC5-44800 with CL46 latency at 1.1V. The 288-pin RDIMM form factor matches the board's memory slots exactly.

Capacity and headroom

Fully populated, the four modules deliver 256GB of Registered ECC memory so every slot runs at rated speed while the buffered architecture offloads the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production workloads. Systems requiring more than 256GB or a different DIMM population order will need a different configuration.

Verified fitment and support

The kit is validated for the Supermicro X14SDW-72C-SP9F motherboard, ensuring the correct Registered RDIMM type and population rules are met. Buyers should still consult their system or motherboard manual for supported capacities and installation steps before purchase. Lifetime replacement coverage and free US-based technical support are included with the kit.

Questions about this item

Will this 288-pin DDR5 RDIMM kit run alongside existing 2Rx4 modules in a Supermicro X14SDW-72C-SP9F?

Yes, the kit matches the board's required 2Rx4 rank, 1.1V voltage, CL46 timing and DDR5-5600 speed so fully populated slots operate at rated specification.

How can I confirm the 256GB kit is recognised at full capacity and speed after installation?

Check the BIOS memory info screen or OS tools — they should show 256GB total, DDR5-5600 (PC5-44800) frequency and CL46 latency with ECC active.

What comes in the box and do I need extra parts such as heatsinks?

The package contains four 64GB DDR5 RDIMM modules; no heat spreaders are included or required for this registered ECC kit.
