Server memory kit for Supermicro H13SSW

This 256GB kit consists of two 128GB DDR5 RDIMMs built for the Supermicro H13SSW motherboard. Each module uses a 2Rx4 registered ECC design that matches the board's memory controller requirements. The kit is intended for administrators expanding capacity on this specific platform.

Registered ECC architecture

Registered buffering offloads the memory controller so all slots can run fully populated at rated speed. On-die ECC detects and corrects single-bit errors to prevent silent data corruption. The modules operate at 1.1V with CL46 timing, matching the voltage and latency the platform expects.

DDR5 5600 speed grade

The kit runs at DDR5 5600 (PC5 44800), the speed grade the Supermicro H13SSW memory controller is validated for. Using modules at this exact data rate ensures the system recognises the full 256GB capacity and operates at the rated frequency without downclocking.

Questions about this item

Will the 288-pin DDR5 RDIMM modules need any firmware updates or scheduled replacement intervals?

DDR5 RDIMM modules have no firmware to update and no scheduled replacement interval; they are solid-state components designed to run for the life of the server unless a hardware fault occurs.

What is the first limit reached when the 256 GB kit runs at DDR5 5600 continuously?

The primary sustained-use limit is the memory controller's maximum supported capacity and population rules on the Supermicro H13SSW, which determine whether all slots can operate at the rated 5600 MT/s.

How much heat and power does the 2Rx4 1.10 V kit produce when fully loaded all day?

At 1.10 V the modules draw low power for DDR5, and with no heat spreader they rely on chassis airflow; registered buffering reduces electrical load on the controller, keeping thermals manageable in a properly cooled server.
