48 GB DDR5 RDIMM for Supermicro H13DSG-OM

This 48 GB DDR5 4800 RDIMM delivers registered ECC memory for the Supermicro H13DSG-OM motherboard. It operates at 1.1 V with CL40 timing in a 2Rx8 configuration across 288 pins. The module matches the exact rank, voltage and timing the board expects for full-speed operation.

Suited for servers needing registered ECC.

Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated capacity while correcting single-bit errors on the fly. Systems that require unbuffered UDIMM or SODIMM modules cannot use this RDIMM. Builders should verify population rules in the motherboard manual before ordering.

48 GB per module at DDR5 4800 with CL40

Each module provides 48 GB at PC5-38400 speed with CL40 latency at 1.1 V. The 2Rx8 registered design supports full-capacity population across all approved slots. Capacity scales with the number of populated slots within the platform limits.

Questions about this item

What motherboard must I already have for this 48GB DDR5 4800 CL40 2Rx8 RDIMM to work?

This module is an exact-match upgrade for the Supermicro H13DSG-OM motherboard and requires that board's 288-pin RDIMM slots.

Can I keep my existing DDR5 RDIMMs and add this 48GB CL40 kit alongside them?

You can mix this kit with other DDR5 RDIMMs only if they share the same 4800 speed, 1.1V voltage, CL40 latency, and 2Rx8 rank, and if the board's population rules allow the combined capacity.

How do I confirm the 48GB DDR5 4800 module is running at its rated speed and ECC is active after installation?

Enter the BIOS or use a hardware-info tool to verify the memory reports 4800 MT/s, CL40 timings, 1.1V, and that ECC is shown as enabled for the full 48GB capacity.
