Exact-match server upgrade

This 768GB kit contains six 128GB DDR5-5600 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SST-G motherboard expects. The modules install as a matched set so the board recognises the full capacity at its rated 5600 MT/s speed without manual tuning.

Capacity and headroom

Six dual-rank 2Rx4 modules populate every slot the platform supports, giving 768GB of addressable memory for dense virtualisation, in-memory databases or large-scale simulation workloads. The registered buffer lets the memory controller drive all slots at full load, while on-die ECC corrects single-bit errors before they reach the application layer.

Thermals and power

Bare modules without heat spreaders rely on the server chassis airflow to stay within spec at the standard 1.10V operating voltage. Registered buffering reduces electrical load on the memory controller, keeping per-DIMM power draw modest even when all six ranks are active under sustained throughput.

Questions about this item

Will this 768GB DDR5 5600 kit work alongside DDR5 modules I already have in my Supermicro H13SST-G?

The board requires 288-pin Registered RDIMMs at 1.1V with CL46 timing. Mixed kits must match this exact rank, voltage, and CAS latency to be recognized at full capacity and rated speed.

How can I verify the 768GB kit is running correctly after installation?

Enter the BIOS or use a hardware monitor to confirm all six 128GB modules are detected, total capacity shows 768GB, speed reads DDR5 5600 (PC5-44800), and timings report CL46 at 1.1V.

What does the box contain and what extra parts are needed?

The package includes the 6x128GB DDR5 5600 CL46 1.1V 2Rx4 ECC Registered RDIMM kit. No additional memory components are required for a compatible Supermicro H13SST-G motherboard.
