Exact-match DDR5 RDIMM kit

This NEMIX RAM kit supplies 256 GB across four 64 GB DDR5 5600 RDIMMs built to the Supermicro X14SDW-64C-SP9F memory controller specification. Registered ECC modules with 2Rx4 organisation and CL46 timing are recognised at full capacity and rated speed without manual tuning.

Practical limits of DDR5 5600 registered ECC

The DDR5 5600 standard delivers 44 800 MT/s bandwidth, yet total capacity and population order remain bound by the motherboard firmware. Registered buffering lets every slot run fully populated, while ECC corrects single-bit errors on the fly.

Build quality and daily handling

Modules ship without heat spreaders, relying on server chassis airflow for cooling. Major OEM Samsung Micron Hynix chips and 1.10 V operation keep thermals manageable in dense configurations. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots during maintenance.

Questions about this item

Should I choose the 256GB kit with four 64GB modules or a smaller capacity for the Supermicro X14SDW-64C-SP9F?

The 256GB kit provides four 64GB modules to fully populate the board's DDR5 RDIMM slots, delivering maximum registered ECC capacity at the rated DDR5 5600 speed.

What does the DDR5 5600 (PC5-44800) rating mean once the modules are installed in the server?

The memory controller will run each 2Rx4 registered DIMM at 5600 MT/s with CL46 latency at 1.1V, providing the full PC5-44800 bandwidth the platform expects.

How does the 288-pin registered ECC interface affect compatibility and performance limits?

The 288-pin RDIMM form factor with registered buffering and ECC is required by the Supermicro X14SDW-64C-SP9F; it enables full-capacity operation across all slots while correcting single-bit errors.
