  • 1TB kit enables full server capacity with eight 128GB modules
  • DDR5 4800 speed matches the board's rated memory controller limit
  • Registered ECC design corrects single-bit errors for production stability
  • 2Rx4 rank and 1.1V voltage align with Supermicro H13DSG-OM requirements
  • 288-pin RDIMM form factor fits the motherboard's memory slots precisely

Targeted Server Upgrade

This 1TB kit delivers eight 128GB DDR5 RDIMMs built to the exact specifications of the Supermicro H13DSG-OM motherboard. It targets administrators who need maximum registered ECC capacity on that specific platform without guesswork. The modules arrive new and ready for deployment in compatible enterprise systems.

Build Integration Requirements

Each module uses the 288-pin RDIMM form factor with registered architecture, so the motherboard must support registered DIMMs and the documented population rules for eight modules. The registered design buffers the command bus, allowing all slots to run fully populated at the rated speed. ECC functionality operates automatically on hardware that enables it.

Capacity and Headroom

The kit provides 1TB of total memory at DDR5 4800 with CL40 timing and 1.1V operation. This density suits virtualization hosts, in-memory databases, and compute clusters that benefit from maximum DIMM-per-slot capacity. Systems requiring more than 1TB per CPU socket or speeds beyond 4800MT/s will exceed what this specific kit delivers.

Questions about this item

Will the 4800 MT/s DDR5 kit sustain its rated speed when all eight 128 GB RDIMMs are populated on the Supermicro H13DSG-OM?

The kit is an exact-match upgrade validated for the H13DSG-OM. Registered architecture and 1.1 V operation let the memory controller run every slot at the rated 4800 MT/s without downclocking.

How much heat and power should I expect from a fully populated 1 TB kit running continuously?

Each module draws 1.1 V with no heat spreader, so total power scales with eight 128 GB RDIMMs. Registered buffering reduces controller load, keeping thermals manageable in a server chassis with normal airflow.

Does the Supermicro H13DSG-OM require any specific BIOS setting or DIMM population order for this 8-module kit?

The board's manual defines supported capacities and the required population sequence. Follow that guide to install all eight 288-pin RDIMMs in the correct slots for full 1 TB recognition.
