Targeted server memory upgrade

This 256GB kit contains two 128GB DDR5 RDIMM modules built for the Supermicro X14SDW-72C-SP9F motherboard. It is intended for administrators who need to maximise the memory capacity of that specific platform. The registered ECC design supports stable operation in multi-socket server environments.

Registered ECC with 4Rx4 organisation

The modules run at DDR5 5600 (PC5-44800) with a CAS latency of 46 at 1.1V. The 4Rx4 rank configuration and registered buffer match the memory controller requirements so the system recognises the full 256GB at rated speed. ECC corrects single-bit errors to prevent silent data corruption.

Two-module kit for full population

The package supplies exactly two 288-pin RDIMMs, allowing you to populate a matched pair of slots in one step. No heat spreaders are included, so airflow in dense server chassis remains unobstructed. The kit is validated for the named Supermicro board and is not compatible with UDIMM or SODIMM slots.

Questions about this item

What does the 5600 MT/s rating mean when the kit is installed in the Supermicro X14SDW-72C-SP9F?

The board's memory controller will run both 128 GB modules at DDR5-5600, delivering PC5-44800 bandwidth per DIMM for a total of 256 GB at rated speed.

How does the DDR5 RDIMM interface and registered design affect usable capacity on this platform?

Registered buffering lets the memory controller drive both 4Rx4 modules at full 5600 MT/s without signal degradation, so the 256 GB kit is recognised at its full rated capacity.

What physical slot and clearance requirements must the chassis meet for these 288-pin modules?

Each 288-pin DDR5 RDIMM needs a standard DDR5 DIMM socket; the kit has no heat spreader, so low-profile CPU coolers or tight server rails will not interfere.
