Server memory kit for Supermicro H13DSG-OM

This 2 TB DDR5 kit contains sixteen 128 GB registered ECC modules rated at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for the Supermicro H13DSG-OM motherboard and delivers the exact rank, voltage and timing the platform expects for full-capacity recognition.

Administrators needing maximum registered ECC

The kit suits IT teams populating every slot on a Supermicro H13DSG-OM with 2Rx4 RDIMMs for enterprise workloads that demand error correction and registered buffering. Builders using consumer boards, laptops or systems that require unbuffered UDIMMs or SODIMMs cannot use these modules.

288-pin DDR5 RDIMM form factor

Each module uses the 288-pin registered DIMM interface required by the H13DSG-OM memory controller. If your server calls for a different pin count, voltage or unbuffered memory this kit will not install or function correctly.

Questions about this item

My Supermicro H13DSG-OM board has 16 DDR5 slots — do I need to fill all of them for this 16×128 GB kit to work?

The kit contains sixteen 128 GB modules. The H13DSG-OM supports up to 16 DIMMs, so you can populate every slot for the full 2 TB capacity.

Will these DDR5-4800 CL40 2Rx4 registered ECC modules run at rated speed if I keep older DDR5 RDIMMs in the remaining slots?

Mixing ranks, speeds or latencies forces the controller to run all channels at the lowest common settings. Replace all DIMMs with this matched 16-module kit for stable DDR5-4800 operation.

After installing all sixteen modules, how can I confirm the server sees the full 2 TB at DDR5-4800 with ECC active?

Check the BIOS memory summary or run dmidecode / lshw on Linux; each of the 16 slots should show 128 GB, 4800 MT/s, CL40, 1.1 V, registered ECC.
