  • 128 GB capacity in a 2 x 64 GB kit for dense server workloads
  • DDR5 5600 speed with CL46 latency matching the motherboard's rated timing
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation at 2Rx4 rank exactly as the Supermicro X14SDW-64CM-SP9F expects
  • 288-pin RDIMM form factor ensures physical and electrical compatibility with the target board

Server Memory Kit

This 128GB kit consists of two 64GB DDR5 RDIMM modules built for the Supermicro X14SDW-64CM-SP9F motherboard. It delivers registered ECC memory that matches the board's required 288-pin form factor and 2Rx4 rank configuration.

Thermals and Power

Modules operate at 1.1V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all slots are populated, supporting stable operation at the rated 5600 speed.

What the Kit Changes

Installing this exact-match kit lets the system recognise the full 128GB capacity at its rated CL46 timing without manual tuning. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Supermicro X14SDW-64CM-SP9F, and what step is often missed?

Power down the server, open the chassis, and insert each 64GB module into the DIMM slots following the motherboard manual's population order; the step often missed is verifying the exact slot sequence for 2Rx4 registered DIMMs so the memory controller initialises all 128GB at DDR5-5600.

What maintenance or replacement will the NEMIX RAM 128GB kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only necessary if a DIMM fails, which is covered by the lifetime replacement warranty.

What limit appears first when the 2Rx4 ECC RDIMMs run sustained workloads at 5600 MT/s?

The registered buffer and ECC logic keep signal integrity at the rated 1.10V CL46 timing, so the first practical limit is the motherboard's maximum supported capacity per slot rather than a thermal or electrical ceiling on the modules themselves.
