  • 256 GB total capacity from two 128 GB modules for maximum memory density
  • DDR5 6400 speed with CL52 latency delivers rated server performance
  • 1 V registered ECC design offloads the controller and corrects single-bit errors
  • 4Rx4 288-pin RDIMM form factor matches Supermicro X14SRA-T population rules exactly
  • Built with major OEM Samsung, Micron or Hynix chips for enterprise-grade reliability

Capacity and purpose

This NEMIX RAM kit delivers 256 GB of DDR5 memory in two 128 GB RDIMM modules. It is built for the Supermicro X14SRA-T motherboard where registered ECC memory is required for full-capacity operation at 6400 MT/s.

Who this suits and who it does not

The 4Rx4 registered ECC design suits servers that need maximum density with error correction and buffered signalling. Buyers who need unbuffered UDIMMs or non-ECC modules for a workstation or desktop platform cannot use this kit.

What to verify before ordering

Confirm that your X14SRA-T firmware revision supports 128 GB per slot and the approved population sequence for a two-module installation. The board manual lists the supported capacities, DIMM order, and any voltage or timing constraints that must match the 1.1 V CL52 specification.

Questions sur cet article

Does my Supermicro X14SRA-T motherboard need a specific BIOS version or CPU to recognise the 256 GB DDR5-6400 RDIMM kit?

The kit is validated for the X14SRA-T at DDR5-6400 (PC5-51200) with 4Rx4 registered ECC at 1.1 V; consult the motherboard manual for supported DIMM population order and any BIOS updates required for full 256 GB capacity.

Can I mix these 128 GB 4Rx4 modules with smaller 1Rx8 or 2Rx8 DDR5 RDIMMs already installed in the server?

Mixing different rank architectures (4Rx4 with 1Rx8 or 2Rx8) on the same channel is not recommended; the X14SRA-T memory controller expects uniform rank-per-channel configuration for stable operation at 6400 MT/s.

After installation, how do I confirm the system is running the full 256 GB at DDR5-6400 CL52 with ECC active?

Enter the BIOS/UEFI or use a tool like dmidecode on Linux; verify total capacity shows 256 GB, speed reads 6400 MT/s (PC5-51200), CAS latency 52, voltage 1.1 V, and ECC status reports "Enabled" or "Corrected".
