NEMIX RAM 384GB DDR5 ECC RDIMM kit

This 384GB kit contains four 96GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1V operation. Registered ECC architecture provides error correction and signal buffering for stable server operation. The modules use 2Rx4 organisation and 288-pin form factor required by the target platform. It is built for the Supermicro H14SST-G motherboard.

Suits Supermicro H14SST-G memory upgrades

This kit fits administrators upgrading a Supermicro H14SST-G motherboard to its full 384GB capacity using matched 96GB RDIMMs. Builders needing UDIMM or SODIMM form factors, non-ECC memory, or lower-density modules should look elsewhere. Systems requiring different voltages, speeds, or rank configurations are not supported by this specific kit.

288-pin DDR5 RDIMM form factor

The 288-pin Registered DIMM format is the single specification that decides compatibility. Only motherboards designed for DDR5 RDIMMs with 2Rx4 rank structure and 1.1V operation will recognise these modules at full capacity and speed. Verify your board's qualified vendor list and population rules before installation.

Questions about this item

Does the 384GB kit ship as four 96GB RDIMMs or are extra modules needed?

The kit contains four 96GB DDR5 RDIMMs for a total of 384GB; no additional modules are required.

Should I pick this 384GB 4800 CL40 kit or a different capacity for the Supermicro H14SST-G?

Choose this 384GB kit when the board's memory population rules allow four 2Rx4 RDIMMs at DDR5-4800; otherwise select a smaller kit that matches the approved DIMM order in the manual.

Will the DDR5-4800 CL40 rating run at that speed once installed in the H14SST-G?

Yes, the modules are spec-matched to the motherboard so the memory controller recognises the full 384GB at the rated DDR5-4800 CL40 1.1V without down-clocking.
