Exact-match 768 GB DDR5 kit

This NEMIX RAM kit delivers 768 GB through twelve 64 GB DDR5-5600 RDIMMs. Each module is a 2Rx4 registered ECC part rated at CL46 and 1.10 V. The kit is built to the precise rank, voltage and timing the Supermicro H14SST-G memory controller expects for full-capacity recognition and rated-speed operation.

Verify manual before ordering

Server and motherboard memory support varies by model, so consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The board requires 288-pin registered RDIMMs, not UDIMMs or SODIMMs, and the population rules must be followed to avoid POST failures.

Registered ECC for full-slot stability

Registered architecture offloads the memory controller so every slot can run fully populated at full capacity. On-the-fly ECC corrects single-bit errors to prevent silent data corruption and unplanned reboots. The modules have no heat spreaders, so ensure your chassis airflow meets the platform's thermal requirements.

Questions about this item

Does the kit include all 12 modules or must any be purchased separately?

The package contains the complete 768GB kit — 12 modules of 64GB each — so nothing extra is required for a full installation.

Should I choose a different capacity or speed for the Supermicro H14SST-G?

This 12x64GB DDR5 5600 CL46 kit matches the board's exact specifications; other capacities or speeds would deviate from the validated configuration.

Will the CL46 latency and 5600 speed run at rated values once installed?

Yes, the modules are spec-matched to the motherboard's memory controller, so they are recognised at full 768GB capacity and operate at DDR5 5600 with CL46 timing.
