192GB DDR5 ECC RDIMM kit for Supermicro H13SST-GC

This 192GB kit provides two 96GB DDR5 6400 Registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It is intended for administrators who need maximum supported capacity on this specific server platform without compatibility guesswork.

288-pin Registered form factor fits the board's

The modules use the 288-pin RDIMM form factor required by the H13SST-GC, not UDIMM or SODIMM. Registered architecture offloads the memory controller so every slot can run fully populated at rated speed, while ECC corrects single-bit errors on the fly. Consult the motherboard manual for approved population order before installation.

6400 speed with CL52 latency at 1.1V

The kit operates at DDR5 6400 (PC5-51200) with CL52 latency and 1.1V, delivering the bandwidth and stability the platform specifies. It comfortably handles memory-intensive workloads such as virtualization, databases and large-scale analytics at full 192GB capacity. Systems requiring more than 192GB or a different DIMM type will need a different solution.

Questions about this item

Will the 96GB 2Rx4 RDIMMs populate all 13 slots on the Supermicro H13SST-GC at full DDR5 6400 speed?

The kit is validated for the H13SST-GC; the board's memory controller recognises the 2Rx4 organisation and 1.1V timing so all supported slots run at the rated PC5-51200 speed when populated per the manual.

How much heat do these 1.1V CL52 modules add when the server runs 24/7 at full load?

Registered DDR5 at 1.10V and CL52 draws modest power per DIMM; with no heat spreaders the modules rely on standard chassis airflow, which is sufficient for continuous operation in the H13SST-GC.

Does the motherboard need a specific BIOS revision or CPU stepping to boot with this 192GB RDIMM kit?

The modules match the H13SST-GC's required 288-pin RDIMM form factor, ECC, registered design and DDR5 6400 spec; the manual lists supported capacities and population order for this configuration.
