512GB DDR5-5600 ECC RDIMM kit for Supermicro

This 512GB kit provides four 128GB DDR5-5600 registered ECC modules built to the exact rank, voltage and timing the Supermicro X14SDW-36C-SP9F memory controller expects. It targets administrators who need maximum supported capacity in every slot without manual tuning.

Upgrade from partial population

The 4Rx4 organization and 1.1V operation let the board run all four channels fully populated at the rated 5600MT/s, replacing smaller or mismatched DIMMs that force downclocking or leave slots empty. The jump is worth it when the workload demands the full 512GB address space and registered buffering for signal integrity.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot remains stable at full capacity during continuous operation, while on-die ECC corrects single-bit errors in real time to prevent silent data corruption. The modules ship without heat spreaders, relying on server chassis airflow to maintain temperature under prolonged throughput.

Questions about this item

What 288-pin DDR5 RDIMM form factor does the Supermicro X14SDW-36C-SP9F require for this 512GB kit?

The motherboard requires 288-pin DDR5 Registered RDIMM modules; this kit provides four 128GB 4Rx4 ECC RDIMMs at 1.1V that match the board's registered architecture and pin layout.

In what population order should the four 128GB 4Rx4 RDIMMs be installed on the X14SDW-36C-SP9F?

Install the modules following the motherboard manual's approved DIMM population sequence for 4Rx4 registered ECC memory to ensure the controller recognises the full 512GB at DDR5-5600 CL46.

When should the 1.1V DDR5-5600 CL46 ECC RDIMMs be replaced if corrected error counts rise?

Replace modules when the system logs show increasing single-bit ECC corrections or any uncorrectable errors, as the registered 4Rx4 chips cannot be serviced and must be swapped as a matched 512GB kit.
