  • 288-pin 2Rx4 form factor fits the Supermicro X14SDW-40C-SP9F memory slots exactly

Purpose-built server upgrade

This 128 GB kit (2 x 64 GB) of DDR5-5600 ECC registered RDIMMs is validated for the Supermicro X14SDW-40C-SP9F motherboard. It delivers the exact rank, voltage and timing the platform expects so every slot is recognised at full capacity and rated speed.

Enterprise stability

Registered architecture offloads the memory controller while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. Modules operate at 1.1 V with CL46 latency and have no heat spreaders, matching the board's mechanical and electrical requirements.

Fitment check required

Server memory support varies by model; consult your system or motherboard manual for approved DIMM population order, maximum capacities per channel and installation steps before purchase. The 288-pin RDIMM form factor this board requires is not interchangeable with UDIMM or SODIMM modules.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules into the Supermicro X14SDW-40C-SP9F motherboard, and what step is often missed?

Power down the server and unplug it. Open the chassis and locate the DDR5 slots. Align the module notch with the slot key, press firmly until both side clips click shut. The step often missed is consulting the motherboard manual for the exact DIMM population order required for 2Rx4 registered modules.

What maintenance or replacement will the 128GB DDR5 ECC RDIMM kit need during its service life?

No scheduled maintenance is required for the memory modules themselves. Keep the server air filters clean and verify cooling airflow so the 1.1V DRAM stays within thermal limits. ECC corrects single-bit errors automatically; if multi-bit errors appear in system logs, replace the affected 64GB module.

What limit appears first when the 5600MHz CL46 registered memory runs under sustained full load?

The primary limit is the memory controller's thermal and electrical envelope when all slots are populated with 2Rx4 registered DIMMs. The registered buffer reduces electrical load, but sustained maximum bandwidth at 5600 MT/s is ultimately constrained by the platform's cooling capacity and power delivery for the 128GB configuration.
