NEMIX RAM 256GB (2×128GB) DDR5 5600 PC5-44800 CL46 4Rx4 1.1V ECC Registered RDIMM memory upgrade

Exact-match DDR5 server kit

This 256 GB kit contains two 128 GB DDR5-5600 registered ECC RDIMMs built to the precise 4Rx4 rank, 1.1 V voltage and CL46 timing the Supermicro X14SDW-64CM-SP9F motherboard expects. The modules are recognised at full capacity and run at their rated PC5-44800 speed without manual tuning. System integrators and server administrators who need guaranteed compatibility with this specific board receive a drop-in upgrade that eliminates guesswork.

Upgrade from smaller or slower DDR5 kits

Replacing a lower-capacity or slower-speed DDR5 kit with this 256 GB matched pair lets the platform address the full memory population the board supports while maintaining registered ECC integrity across every slot. The jump is worth it when workloads demand the maximum registered DIMM capacity the motherboard can populate and when single-bit error correction must remain active under full load. Buyers who need unbuffered UDIMMs, SODIMMs or a different DDR generation cannot use this kit.

Verify motherboard population rules

Before ordering, consult the Supermicro X14SDW-64CM-SP9F manual for supported capacities, approved DIMM population order and installation steps to ensure the 288-pin RDIMM form factor and 4Rx4 rank are accepted in your configuration. Confirm the server chassis provides adequate clearance for the installed modules and that the memory controller firmware recognises the kit at the rated DDR5-5600 speed. Systems requiring a different pin count, voltage or rank structure will not accept this memory.
