Exact-match DDR5 RDIMM kit

This NEMIX RAM kit delivers 256GB (2 x 128GB) of DDR5-4800 ECC Registered memory built to the precise rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. The 2Rx4 organization and CL40 latency let the board recognize full capacity at rated speed without manual tuning.

288-pin Registered form factor

The modules use the 288-pin RDIMM form factor this motherboard requires, not UDIMM or SODIMM. Registered architecture offloads the memory controller so every populated slot runs at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption.

1.10V operation without heat spreaders

Running at 1.10V keeps power draw low in dense server configurations where multiple kits fill every channel. The modules ship without heat spreaders, relying on chassis airflow to maintain stable temperatures under sustained enterprise workloads.

Questions sur cet article

Will the 1.1V DDR5 4800MHz CL40 modules throttle or error out during 24/7 server workloads?

The RDIMM registered buffer offloads the memory controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly, preventing silent corruption during sustained use.

How much heat and power will the 2x128GB kit add to a fully loaded Supermicro H14DSG-O-CPU chassis?

Each module operates at 1.1V without a heat spreader; registered buffering reduces electrical load on the CPU memory controller, keeping thermals and draw low enough for standard server airflow.

Does the Supermicro H14DSG-O-CPU motherboard need a specific BIOS version or CPU stepping to recognise the 256GB 2Rx4 kit?

The kit is spec-matched to the board's 288-pin RDIMM slots and population rules; consult the motherboard manual for supported capacities, approved DIMM order, and any required firmware updates before installation.
