Exact-match DDR5 server kit

This 192 GB kit contains four 48 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 timings and 1.10 V operation. Each module uses a 2Rx8 registered ECC design that matches the Supermicro H14SSL-NT memory controller requirements. The 288-pin form factor fits the board's DIMM slots without adapters.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller so all four slots can run fully populated at the rated 4800 MT/s speed. ECC circuitry detects and corrects single-bit errors during continuous operation, preventing silent data corruption. The 2Rx8 organisation maintains consistent bandwidth across extended workloads.

Thermals noise power

Modules operate at the standard DDR5 1.10 V without heat spreaders, relying on chassis airflow for cooling. Registered DIMMs draw slightly more power than unbuffered equivalents but stay within the motherboard's power budget. No active cooling components are present, so acoustic output depends entirely on system fans.

Questions about this item

How much power does the 192GB kit draw at its 1.1V operating voltage?

Each module runs at 1.1V DDR5 standard voltage; total power depends on server load and the number of populated slots.

What motherboard slot type is required for these 288-pin RDIMMs?

The Supermicro H14SSL-NT must provide DDR5 RDIMM slots; UDIMM or SODIMM sockets will not accept this kit.

Will the 2Rx8 registered ECC modules work in a board that only supports single-rank UDIMMs?

No — this kit uses registered 2Rx8 ECC RDIMMs, which require a motherboard designed for registered DDR5 memory.
