Exact-match DDR5 384GB kit

This 384GB kit contains four 96GB DDR5 RDIMMs running at 6400 MT/s with CL52 latency and 1.1V operation. It is built for the Supermicro H13SST-GC motherboard where the memory controller expects 2Rx4 registered ECC modules in a 288-pin form factor.

Capacity and headroom

Four slots are fully populated with 96GB each, delivering 384GB of registered ECC memory for multi-socket workloads. The registered architecture keeps electrical load low so every slot runs at rated speed, while ECC corrects single-bit errors before they reach production. Buyers who need more capacity than the board's maximum population cannot use this kit.

Build and daily implications

Modules ship without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots. Population order must follow the motherboard manual exactly; incorrect sequencing will stop the system from posting at full capacity.

Questions about this item

Will the 4 x 96GB DDR5 6400 RDIMMs run at rated speed in my Supermicro H13SST-GC alongside any existing DDR5 ECC RDIMMs?

The kit is spec-matched to the H13SST-GC memory controller at 1.1V CL52 2Rx4. Mixing with other DDR5 ECC RDIMMs is supported only if they share the same voltage, rank, and timing; otherwise the board will downclock all modules to the slowest common settings.

How can I confirm the 384GB kit is operating at DDR5 6400 with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 6400 MT/s, voltage shows 1.1V, and ECC status is reported as enabled or active for all four slots.

Does the 384GB kit include heat spreaders or any mounting hardware, and what must I supply separately?

The package contains only the four 96GB 288-pin DDR5 ECC RDIMM modules. No heat spreaders, brackets, or tools are included; the server chassis and motherboard provide all required retention.
