Exact DDR5 RDIMM kit for Supermicro H14DSG-OD

This NEMIX RAM kit supplies 256 GB across eight 32 GB DDR5-6400 registered ECC modules. Each stick runs at 1.1 V with CL52 timing and a 2Rx8 rank layout that matches the motherboard's memory controller requirements. The 288-pin RDIMM form factor fits the server board's DIMM slots directly.

Suited for fully populated H14DSG-OD servers

Administrators expanding a Supermicro H14DSG-OD to its maximum supported capacity with verified registered ECC memory will find this kit plugs in and runs at rated speed without manual tuning. Builders needing UDIMM, SODIMM or non-ECC modules for other platforms cannot use these registered DIMMs.

Registered ECC with 2Rx8 organisation

The dual-rank registered design offloads the memory controller so all eight slots operate at full DDR5-6400 throughput while ECC corrects single-bit errors in flight. This combination of registration, ECC and 2Rx8 density is the single specification that determines whether the motherboard recognises the full 256 GB at rated performance.

Questions about this item

What motherboard must I already own for this 256GB DDR5 6400MHz CL52 ECC RDIMM kit to be recognised at full capacity?

The kit is spec-matched for the Supermicro H14DSG-OD motherboard; its memory controller expects the exact 2Rx8 rank, 1.10V voltage and CL52 timing so all eight slots populate at the rated 6400MHz speed.

Can I keep my existing DDR5 RDIMMs and add these eight 32GB modules alongside them?

Mixing ranks or capacities breaks the board's population rules; the H14DSG-OD requires identical 2Rx8 Registered DIMMs in every occupied slot, so you must replace any older modules with this full 8×32GB kit.

How do I verify the kit is running at 6400MHz with ECC active after installation?

Enter the BIOS or run a tool such as dmidecode — each DIMM should report 6400MT/s, CL52, 1.10V, Registered ECC and 2Rx8 organisation across all eight slots.
