Exact-Match DDR5 Server Kit

This 512 GB kit delivers four 128 GB DDR5 5600 RDIMM modules built to the Supermicro X14SDW-72C-SP9F motherboard's exact specifications. Registered ECC architecture with 4Rx4 organisation and CL46 timing at 1.1 V ensures the memory controller recognises full capacity at rated speed. It is designed for administrators who need guaranteed compatibility without manual tuning. Builders using consumer boards or unbuffered DIMM slots cannot use this registered ECC kit.

Thermals and Power Draw

Operating at the standard DDR5 voltage of 1.1 V keeps power draw predictable across all four modules in a fully populated server. The modules ship without heat spreaders, relying on chassis airflow for cooling in typical rack environments. Registered buffering reduces electrical load on the memory controller, contributing to stable operation under sustained workloads. Acoustic output is determined by the system fans rather than the memory itself.

What the Kit Changes

Populating every slot with matched 4Rx4 registered ECC DIMMs lets the platform reach its maximum supported capacity while single-bit error correction runs continuously in the background. The exact rank, voltage and timing alignment eliminates the trial-and-error phase that often follows generic memory upgrades. No additional software or firmware tools are included; configuration is handled entirely through the system BIOS.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the correct order for the Supermicro X14SDW-72C-SP9F motherboard?

Follow the motherboard manual's population rules exactly. The board requires a specific slot sequence for four 4Rx4 registered DIMMs to initialise at the rated 5600 MHz speed.

What maintenance will this 4Rx4 ECC registered kit require over its service life?

No routine maintenance is needed. ECC corrects single-bit errors automatically, and the registered design reduces electrical load on the memory controller for stable long-term operation.

At what point does the CL46 latency limit sustained throughput on this 5600 MHz kit?

CL46 is the rated timing at 5600 MHz. Under sustained load the CAS latency remains fixed; the memory controller cannot push lower timings without exceeding the module's validated specification.
