  • 192 GB total capacity for memory-intensive workloads with four 48 GB modules
  • DDR5 4800 speed (PC5-38400) matches the controller's rated frequency
  • Registered ECC design with 2Rx8 organisation corrects single-bit errors and stabilises full-slot population
  • 10 V operation at CL40 latency meets the board's exact voltage and timing requirements
  • Validated for Supermicro H13SSL-N motherboard using 288-pin RDIMM form factor

Capacity and fit

This 192GB kit delivers four 48GB DDR5 modules built to the 288-pin RDIMM standard. It is made for servers and workstations that require registered ECC memory and will not accept unbuffered DIMMs.

Build integration

The modules run at 1.10V and present a 2Rx8 organisation that the memory controller expects, so the system recognises the full 192GB at the rated 4800 speed. Registered buffering offloads the controller, allowing every slot to stay populated without signal degradation, while ECC corrects single-bit errors before they reach applications. Verify your motherboard manual for supported capacities and the required population order before installation.

Sustained operation

Rated CL40 at DDR5-4800 (PC5-38400), the kit maintains its timing and voltage under continuous load rather than only in short bursts. The registered architecture keeps electrical loading stable across all four slots during extended workloads, and ECC protection remains active throughout, reducing the risk of silent data corruption during long-running compute or database tasks.

Questions about this item

What sustained-load limit appears first with four 48 GB DDR5-4800 registered ECC modules?

The memory controller on the Supermicro H13SSL-N motherboard reaches its maximum supported DIMM population before any thermal or power ceiling, so full 192 GB capacity is recognised at the rated 4800 MT/s speed.

How does the registered DDR5 kit behave for noise, heat and power during continuous operation?

Registered architecture offloads the memory controller, the modules run at 1.1 V without heat spreaders, and they add no audible noise; typical server airflow handles the thermal load.

What must already be installed for this 288-pin RDIMM kit to function?

A Supermicro H13SSL-N motherboard with DDR5 RDIMM slots, a compatible CPU that supports registered ECC memory, and the correct DIMM population order shown in the board manual.
