  • Validated for Supermicro H13SST-G motherboard ensuring correct 288-pin RDIMM fitment and population rules

Exact-match DDR5 upgrade kit

This 192GB kit contains four 48GB DDR5 6400 Registered ECC RDIMM modules built to the precise rank, voltage and timing the Supermicro H13SST-G memory controller expects. The 2Rx8 organization and CL52 latency let the board recognize full capacity at rated speed without manual tuning.

Thermals power and noise

Modules operate at 1.1V with no heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller so every slot runs fully populated at full speed. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

Build fit and requirements

The 288-pin RDIMM form factor fits only boards that require Registered DDR5; it will not work in UDIMM or SODIMM slots. Population order and maximum supported capacity vary by motherboard revision, so consult the system manual before installation. No heat spreader means taller CPU coolers have extra clearance above the DIMMs.

Questions about this item

How do I install the four 48 GB DDR5 RDIMMs on the Supermicro H13SST-G and which population step is often missed?

Install one module per channel following the board's labelled slot order; the step most builders skip is checking the manual for the exact sequence required when all four slots are filled.

What maintenance or replacement will this 192 GB DDR5 ECC RDIMM kit need over its service life?

No routine maintenance is required; if a module fails the lifetime replacement warranty covers a direct swap of the defective 48 GB stick.

What limit appears first when the Supermicro H13SST-G runs this 6400 MT/s DDR5 kit fully populated under sustained load?

The memory controller's maximum supported speed with four 2Rx8 registered DIMMs installed is the first ceiling you hit; the modules themselves are rated for 6400 MT/s at CL52 and 1.1 V.
