Size 256GB 2X128GB

  • 256 GB kit lets the Supermicro X14SDW-36C-SP9F reach its maximum supported capacity
  • DDR5 5600 (PC5-44800) speed matches the board's rated frequency for full bandwidth
  • CL46 latency and 1.10 V voltage are the exact timings the memory controller expects
  • Registered ECC 4Rx4 architecture offloads the controller and corrects single-bit errors on the fly
  • 288-pin RDIMM form factor is the only module type this motherboard accepts

System-Specific DDR5 256 GB Kit

This 256 GB kit (2 x 128 GB) is a registered ECC RDIMM upgrade built for the Supermicro X14SDW-36C-SP9F motherboard. It targets administrators who need maximum supported capacity on this exact platform without manual tuning. The modules arrive at the precise rank, voltage and timing the board expects.

Capacity and Headroom

Each 128 GB module uses a 4Rx4 organisation, so two DIMMs fill the capacity ceiling this board recognises at DDR5-5600 speed. Registered buffering lets every slot run fully populated while ECC corrects single-bit errors on the fly. Workloads that exceed 256 GB will require a different platform.

Upgrade Path

The kit replaces lower-capacity DDR5 RDIMMs or a partially populated configuration on the same motherboard. The jump is worth it when virtualisation density, in-memory databases or large dataset processing hit the previous memory limit. It does not fit boards that require UDIMM or SODIMM form factors.

Questions about this item

Will this 256GB DDR5 5600 kit run alongside existing RDIMMs in my Supermicro X14SDW-36C-SP9F?

The kit is spec-matched to the X14SDW-36C-SP9F motherboard for DDR5 5600 PC5-44800 4Rx4 1.1V CL46 Registered ECC; consult the board manual for approved population order and maximum capacity per channel.

How do I confirm the 2x128GB modules are recognised at full speed after installation?

Enter BIOS or use a hardware utility to verify both DIMMs show 128GB each, DDR5 5600 MT/s, 1.10V, CL46 and ECC active with no memory errors reported.

What comes in the box and is anything else needed to install the 288-pin RDIMMs?

The package contains the 256GB 2x128GB DDR5 5600 CL46 4Rx4 ECC RDIMM kit only; no heat spreaders or extra cables are included and no additional parts are required for standard server DIMM slots.
