Capacity and fit

This 192GB kit (4 x 48GB) DDR5 6400 PC5-51200 CL52 1.1V 288-pin ECC Registered RDIMM is built for the Supermicro H13DSH motherboard. The 2Rx8 rank structure and registered design match the board's memory controller so the full capacity is recognised at rated speed. It targets server administrators who need maximum registered ECC capacity on this specific platform.

Before ordering

Confirm the H13DSH manual for approved DIMM population order, maximum capacity per slot and any BIOS version requirements. The motherboard requires 288-pin RDIMM modules; UDIMM or SODIMM will not fit or function. Verify that your configuration supports four 48GB 2Rx8 registered DIMMs at 1.1V before purchase.

Thermals and power

Modules operate at 1.1V without heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all four slots are populated. Power draw scales with the 192GB capacity and 6400 speed; ensure server cooling is adequate for fully populated memory channels under sustained workloads.

Questions about this item

What is included in the NEMIX RAM DDR5 6400 192GB kit and do I need to buy anything else for installation?

The kit contains four 48GB DDR5 6400 ECC Registered RDIMMs for a total of 192GB. No additional parts are required; the modules install directly into the Supermicro H13DSH motherboard's 288-pin slots.

Should I choose this 192GB (4x48GB) CL52 kit or a different capacity for my Supermicro H13DSH?

This 192GB kit uses four 48GB 2Rx8 modules at CL52 and 1.1V, matching the board's validated population rules. Select it when your workload needs the full 192GB capacity; otherwise choose a smaller validated kit.

What does the DDR5 6400 (PC5-51200) rating mean once the modules are running in the H13DSH?

The modules operate at 6400 MT/s with CL52 latency at 1.1V, delivering the rated bandwidth and error-correcting stability the server's memory controller expects when fully populated.
