Capacity and fit

This 1.1 TB kit contains twelve 96 GB DDR5 RDIMMs built for the Supermicro H13DSG-O-CPU-D motherboard. Registered ECC modules offload the memory controller so every slot runs at the rated 4800 MT/s without manual tuning. IT teams and system integrators use it to max out supported capacity in a single validated package.

Thermals and power

Each module operates at 1.10 V with a CL40 timing and no heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory bus, keeping power draw predictable across all twelve slots. In typical server workloads the kit runs within standard DDR5 thermal limits without additional fan speed changes.

Upgrade scope

The kit replaces smaller-capacity RDIMM sets or mixed-rank configurations that limit total memory or force downclocking. It is not suited for boards that require UDIMM or SODIMM form factors, nor for systems that do not support 2Rx4 registered ECC at 4800 MT/s. Verify the motherboard manual for approved population order before installing.

Questions about this item

How do I install the 12 DDR5 RDIMMs into the Supermicro H13DSG-O-CPU-D and which slot order should I follow?

Power down the server, open the chassis, and insert each 288-pin module into the DIMM slots following the population sequence shown in the motherboard manual; the board requires Registered ECC RDIMMs and will not accept UDIMMs or SODIMMs.

What maintenance or replacement will the 1.1TB DDR5 ECC RDIMM kit need during its service life?

No routine maintenance is required; the modules have no heat spreaders and rely on server airflow, so keep intake filters clean and if a module fails it is covered by a lifetime replacement warranty.

What is the first limit reached when the 12x96GB DDR5-4800 CL40 kit runs sustained workloads?

The memory controller on the H13DSG-O-CPU-D caps the kit at DDR5-4800 with CL40 timings at 1.10V, so bandwidth and latency are fixed by the platform rather than thermal throttling.
