  • 288-pin RDIMM form factor fits the required server board slots

Kit purpose

This 192 GB DDR5 registered ECC kit contains four 48 GB modules built for the Supermicro H14DSG-O-CPU motherboard. It targets administrators who need the full 192 GB capacity at the board's native 4800 MT/s speed with CL40 timing and 1.1 V operation.

Before ordering

Verify that your H14DSG-O-CPU system manual approves a four-DIMM population of 48 GB registered modules at 2Rx8 rank. Confirm the required slot sequence and any BIOS version minimums so the memory controller initialises every module at the rated 4800 MT/s data rate.

Build and connectors

Each module uses the 288-pin RDIMM form factor without a heat spreader, relying on server chassis airflow for cooling. The registered buffer reduces electrical load on the memory controller when all slots are filled, while on-die ECC corrects single-bit errors to maintain data integrity in production workloads.

Questions about this item

Does the 192GB kit include all four 48GB modules, or do I need to buy anything else?

The kit ships as four 48GB DDR5 4800 RDIMMs (part MR38400-4828K4) — no extra modules or accessories are required for a full 192GB install.

Why choose this 4800 CL40 2Rx8 kit instead of a different speed or rank?

The Supermicro H14DSG-O-CPU memory controller expects DDR5-4800, 1.1V, CL40, 2Rx8 registered ECC; matching those exact specs ensures full-capacity recognition and rated-speed operation.

What does the 4800 MT/s rating actually deliver once the modules are seated in the server?

At 4800 MT/s (PC5-38400) the memory runs at its rated throughput with ECC error correction active, giving the bandwidth the platform was validated for without down-clocking.
