Capacity and form factor

This NEMIX RAM kit provides 384GB of DDR5 server memory across four 96GB modules. Each 288-pin RDIMM operates at 4800MHz with CL40 latency and 1.1V, using a 2Rx4 registered ECC design built for the Supermicro H14DST-FL motherboard.

Suited workloads and limits

The registered ECC architecture supports full-capacity population and on-the-fly error correction for databases, virtualization and other production workloads that cannot tolerate silent data corruption. Systems requiring unbuffered UDIMMs, SODIMM form factors or non-ECC memory should look elsewhere.

Kit contents and practical impact

The package delivers the exact four-module kit specified by the board's population rules, so the memory controller recognises the full 384GB at rated speed without manual tuning. Major OEM Samsung, Micron or Hynix components provide the stability expected in continuously running server environments.

Questions about this item

Will this 384GB kit work in a Supermicro H14DST-FL without any other memory installed?

Yes, the kit is an exact-match upgrade for the H14DST-FL; install the four 96GB RDIMMs following the board's population order and the server will recognise the full 384GB at DDR5-4800.

Can I keep my existing DDR5 4800 RDIMMs and add this 4x96GB kit to the same H14DST-FL?

Mixing ranks or capacities can prevent full-speed operation; the board's manual specifies which slots must match, so populate all channels with identical 2Rx4 modules for stable DDR5-4800 performance.

How do I confirm the kit is running at its rated CL40 1.1V after installation?

Enter the BIOS or use a tool such as dmidecode to verify each DIMM shows 4800 MT/s, CAS latency 40, 1.10 V and registered ECC status.
