NEMIX RAM 1.5TB DDR5-6400 ECC RDIMM Kit

This NEMIX RAM kit delivers 1.5TB of DDR5 memory across twelve 128GB Registered DIMMs. Each module runs at 6400 MT/s with CL52 latency at 1.1V and uses a 2Rx4 organisation. The 288-pin RDIMM form factor and ECC Registered design match the Supermicro H14DSG-OD motherboard requirements exactly.

For Supermicro H14DSG-OD Servers Needing Maximum

This kit suits administrators populating every slot on a Supermicro H14DSG-OD board to reach the platform's supported memory ceiling. It is not for systems that accept only unbuffered UDIMMs or SODIMMs, nor for builds that require a lower total capacity or a different pin count.

12 x 128GB 2Rx4 Registered ECC Configuration

The twelve-module 2Rx4 Registered ECC layout is the single specification that determines compatibility with the H14DSG-OD memory controller. The board's population rules expect this exact rank structure and voltage so the full 1.5TB is recognised at the rated 6400 MT/s speed.

Questions about this item

What comes in the NEMIX RAM 1.5TB DDR5 6400 kit and do I need anything else to install it?

The kit includes twelve 128GB DDR5 6400 RDIMM modules for a total of 1.5TB. No additional parts are required; each module is a 288-pin registered DIMM that fits directly into the Supermicro H14DSG-OD memory slots.

Should I choose this 12x128GB CL52 kit or a different capacity for my Supermicro H14DSG-OD?

This 12x128GB kit delivers 1.5TB at DDR5 6400 with CL52 timing and 1.1V operation. Select it when your workload needs the maximum supported capacity across all twelve slots; choose a smaller kit only if your memory requirement is lower.

What does the DDR5 6400 CL52 rating mean once the modules are installed in the H14DSG-OD?

The memory will run at 6400 MT/s with a CAS latency of 52 cycles at 1.1V. The registered 2Rx4 organisation lets the memory controller drive all twelve slots at this rated speed while ECC corrects single-bit errors in real time.
