128GB DDR5 RDIMM kit for Supermicro H13DSG-OM

This 128GB kit contains eight 16GB DDR5 4800 RDIMM modules built to the exact rank, voltage and timing the Supermicro H13DSG-OM memory controller expects. Each module is a 1Rx8 registered ECC DIMM running at 1.10V with CL40 latency. The 288-pin form factor matches the board's registered DIMM slots so the system recognises the full capacity at rated speed.

Capacity and headroom with eight 16GB modules

Fully populating the supported slots delivers 128GB of registered ECC memory for multi-socket workloads, virtualisation hosts and database buffers that benefit from maximum DIMM density. The registered architecture offloads the memory controller so every slot runs fully populated at DDR5 4800 without signal degradation. Workloads that exceed 128GB or need higher frequencies than PC5 38400 will require a different platform or memory configuration.

Build fit: registered ECC, 1.10V, 288-pin RDIMM

The kit uses the registered RDIMM form factor this motherboard requires, not UDIMM or SODIMM. Installation must follow the board's validated population order to initialise correctly. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production. Systems needing unbuffered memory, non-ECC modules or a different pin count cannot use this kit.

Questions about this item

Will these 1Rx8 registered DIMMs work with the existing memory slots on my Supermicro H13DSG-OM motherboard?

Yes, the 288-pin RDIMM form factor matches the slots on the Supermicro H13DSG-OM. The kit is spec-matched to the board's memory-population rules so all eight 16 GB modules are recognised at full capacity and run at DDR5-4800 with CL40 timing at 1.1 V.

How can I confirm the kit is running at the rated DDR5-4800 CL40 speed after installation?

Enter the BIOS or use a system-information tool such as CPU-Z and verify the memory frequency reads 4800 MT/s (PC5-38400) with CAS latency 40 and voltage at 1.10 V. The registered ECC design also logs corrected errors, confirming the modules are active and stable.

Does the package include only the eight 16 GB RDIMMs or are any extra parts such as heat spreaders or cables supplied?

The box contains the 128 GB kit comprised of eight 16 GB DDR5-4800 1Rx8 ECC registered RDIMMs. No heat spreaders, cables or additional accessories are included.
