Capacity and Compatibility

This NEMIX RAM kit delivers 384GB of DDR5 memory across six 64GB Registered ECC RDIMMs. It is built for the Supermicro H14SST-GE motherboard, matching the board's 288-pin DDR5 slot layout and memory-population rules.

Ideal Use and Limitations

The kit suits administrators who need the exact 2Rx4 Registered ECC configuration that allows full-slot population at rated speed. It is not for systems that accept only unbuffered UDIMMs, require SODIMM form factors, or cannot supply the specified 1.10V operating voltage.

Deciding Specification

The registered 2Rx4 architecture with ECC at CL52 latency is the single specification that determines whether this kit will be recognised at full capacity and run at DDR5-6400 on the target platform.

Questions about this item

Should I choose the 384GB 6x64GB kit or a smaller capacity for my Supermicro H14SST-GE?

The 384GB 6x64GB kit fully populates six slots with 2Rx4 registered ECC modules at DDR5-6400 CL52 1.10V, matching the board's population rules for maximum capacity.

What does the DDR5-6400 rating deliver once installed in the server?

The modules run at 6400 MT/s with CL52 latency at 1.10V, providing the exact bandwidth and timing the memory controller expects for stable full-speed operation.

How does the 288-pin RDIMM interface and registered ECC design affect real-world use?

The 288-pin registered ECC RDIMM format offloads the memory controller, allows all six slots to run at full 6400 MT/s, and corrects single-bit errors to prevent data corruption.
