Exact-fit 576GB DDR5 kit for Supermicro H13SST-GC

This NEMIX RAM kit delivers 576GB in twelve 48GB DDR5 6400 modules built to the CL52 1.1V 2Rx8 registered ECC specification the Supermicro H13SST-GC memory controller expects. The 288-pin RDIMM form factor matches the board's DIMM slots exactly so every stick is recognised at full capacity and rated speed.

Verify manual population rules before ordering

Server memory support varies by model and BIOS revision. Consult the Supermicro H13SST-GC manual for approved capacities, the required DIMM population order across all twelve channels, and the correct installation sequence to avoid a no-post condition.

Registered ECC sustains full load without

The registered architecture buffers address and command signals so the memory controller remains stable when all twelve slots run continuously at DDR5 6400. ECC corrects single-bit errors on the fly preventing silent data corruption during prolonged compute or virtualization workloads.

Questions about this item

Does the kit include all 12 modules or do I need to buy additional DIMMs separately?

The kit contains 12 x 48 GB DDR5 RDIMMs for a total of 576 GB; no extra modules are required.

Why choose the 12 x 48 GB configuration instead of a smaller kit?

This 576 GB kit fills every slot on the Supermicro H13SST-GC with 2Rx8 registered ECC DDR5-6400 modules at the rated 1.1 V and CL52.

Will the memory run at DDR5-6400 CL52 once installed in the Supermicro H13SST-GC?

Yes — the modules are spec-matched to the board's memory controller so they are recognised at full capacity and operate at the rated DDR5-6400 CL52 1.1 V settings.
