  • Massive 512 GB capacity across four 128 GB modules
  • DDR5 6400 MHz CL52 speed for high-throughput workloads
  • ECC registered design detects and corrects data errors
  • 1 V operation reduces server power draw
  • Validated for Supermicro X14SBM-TP4F compatibility

Capacity and Configuration

This NEMIX RAM kit delivers 512GB of DDR5 memory across four 128GB registered DIMMs. It is built for Supermicro X14SBM-TP4F servers and workstations that require high-density ECC RDIMM modules.

Suited Use Cases

The kit suits administrators running virtualisation, large databases or AI workloads on the validated Supermicro platform. It is not for systems that cannot accept registered ECC memory, lack 288-pin DDR5 slots or require unbuffered consumer DIMMs.

Installation Notes

Each module installs in a standard 288-pin DDR5 slot at 1.10V with CL52 timing. Common issues include populating slots in the wrong order for the motherboard topology and forgetting to enable ECC in the firmware before boot.

Questions about this item

Does my Supermicro X14SBM-TP4F motherboard need DDR5 RDIMM slots to use this 512GB kit?

Yes, the kit uses 288-pin DDR5 RDIMM modules, so the board must provide DDR5 RDIMM slots for installation.

Can I mix these 6400MHz CL52 modules with slower DDR5 RDIMMs already in my server?

The motherboard will run all installed DDR5 RDIMMs at the speed of the slowest module, so mixing is possible but reduces overall memory frequency.

How can I verify the full 512GB capacity is recognised after installing the four 128GB sticks?

Check the system BIOS or operating system memory report; it should show 512GB total across the four DDR5 RDIMM slots.
