Exact-match DDR5 RDIMM kit for Supermicro H14DSG-OM

This 128GB kit contains two 64GB DDR5-4800 registered ECC modules built to the 288-pin RDIMM form factor. It is designed for servers that require registered memory with error correction and operates at 1.1V with CL40 latency. The 2Rx4 organization matches the memory controller expectations for full-capacity recognition.

Check your server manual for population rules

Supported capacities, approved DIMM slot order, and maximum module count vary by motherboard revision and BIOS version. The H14DSG-OM requires registered RDIMMs, not unbuffered UDIMMs or SODIMMs, so verify the exact configuration your chassis and firmware allow. Installing modules in the wrong slots can prevent boot or limit usable memory.

Kit delivers two matched modules for dual-channel

The pair is tested together so both DIMMs share identical timing, voltage, and rank characteristics, allowing the memory controller to initialize them at the rated 4800 MT/s speed. No heat spreaders are included, so airflow across the bare PCB must be provided by the server chassis fans. The package contains only the two memory modules.

Questions about this item

Does the 128GB kit include both 64GB modules or do I need to buy a second kit?

The kit contains two 64GB RDIMMs for a total of 128GB; nothing else is required to reach that capacity.

Should I choose the CL40 4800MHz version or a different speed grade for the H14DSG-OM?

This module matches the board's qualified DDR5-4800 CL40 1.1V 2Rx4 specification exactly.

Will the registered ECC design run at the full 4800MT/s when all slots are populated?

Yes, the registered architecture offloads the controller so every populated slot operates at the rated 4800MT/s with ECC active.
