Capacity and configuration

This 2TB kit provides 16 modules of 128GB each, filling every slot on a Supermicro H14DSG-OD motherboard. The 2Rx4 Registered ECC design lets the memory controller address the full population at rated speed without signal degradation.

Speed and headroom

DDR5 4800 (PC5-38400) CL40 at 1.1V delivers the bandwidth the platform specifies for fully loaded operation. Workloads that exceed the 2TB limit will require a different motherboard or a scale-out architecture.

What the kit changes

The matched 16-piece set eliminates mixed-rank variability so the server posts at full capacity on first boot. Registered buffering and on-die ECC protect data integrity across all slots, reducing unplanned downtime in production environments.
