Capacity and configuration

This is a 192GB DDR5 ECC registered DIMM kit built as four 48GB modules. It is intended for servers and workstations that require maximum memory density per channel with error correction and registered signalling.

Build integration

The 288-pin RDIMM form factor fits only motherboards designed for registered DDR5 memory, such as the Supermicro H13SSL-NT. Registered buffering reduces electrical load on the memory controller, allowing all four slots to be populated at full capacity without signal degradation. ECC corrects single-bit errors in real time, protecting data integrity in production workloads.

Sustained operation

Rated at DDR5-6400 with CL52 latency and 1.1V operation, the kit maintains its specified speed and timing under continuous load. The 2Rx8 organisation and major OEM DRAM chips provide consistent throughput for virtualization, database, and compute tasks that keep memory fully utilised for extended periods.

Questions about this item

What is the first limit reached under sustained full-capacity load with four 48GB RDIMMs?

The registered DDR5 6400 modules operate at 1.1V with CL52 timing, so the memory controller’s thermal and signal-integrity ceiling is the first constraint when all four slots are populated continuously.

How much power do the four 48GB DDR5 6400 RDIMMs draw at 1.1V during all-day operation?

Each 2Rx8 module runs at 1.1V, so total kit power scales with the memory controller’s sustained bandwidth demand rather than a fixed per-DIMM wattage.

Which motherboard must already be installed for this 192GB kit to function?

The kit is validated for the Supermicro H13SSL-NT motherboard, which provides the required 288-pin RDIMM slots and registered ECC memory controller.
