Exact-match DDR5 6400 kit for Supermicro H13SST-GC

This 192GB kit contains four 48GB DDR5 6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It is intended for administrators upgrading that specific motherboard to its full supported capacity with server-grade stability.

Install by following the motherboard manual

Registered RDIMMs must be seated in the exact slot sequence the manual specifies; using the wrong order or mixing ranks will prevent the system from recognising the full 192GB. The 288-pin modules key only one way, so physical insertion is straightforward when the population rules are observed.

Four 48GB modules deliver 192GB at DDR5 6400 CL52

Registered architecture offloads the controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly. Workloads that exceed 192GB or require faster timings than CL52 will need a different platform.
