System-Specific DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 768 GB of DDR5 memory in twelve 64 GB modules. It runs at 4800 MT/s with CL40 latency at 1.1 V. The registered ECC design targets Supermicro H14DST-F servers that require full-capacity stability.

Verify Motherboard Population Rules

Confirm the H14DST-F manual for approved DIMM slot order, maximum capacity per channel, and any BIOS version requirements. The board must accept 288-pin registered DDR5 RDIMMs with 2Rx4 organisation to recognise the full kit.

Registered Buffer Offloads the Controller

The registered architecture reduces electrical load on the memory controller when all twelve slots are populated. ECC corrects single-bit errors in-flight, protecting data integrity in production workloads. Modules lack heat spreaders, so chassis airflow must handle thermal dissipation.

Questions about this item

What comes in the box and do I need to buy anything else to install this 768GB kit?

The box contains twelve 64GB DDR5 4800 CL40 ECC Registered RDIMM modules totalling 768GB. No extra parts are required for installation on a compatible Supermicro H14DST-F motherboard.

How do I decide between this 12x64GB kit and a smaller capacity for my Supermicro H14DST-F?

Choose this 768GB kit when your workload needs the maximum supported capacity across all twelve slots. Select a smaller kit if your application fits in less memory and you want to leave slots open for future expansion.

What does the DDR5 4800 CL40 rating mean once the modules are running in the server?

The memory will operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1V. Registered buffering and ECC keep every slot stable at full population while correcting single-bit errors on the fly.
