128GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 128GB across four 32GB modules running at DDR5 6400 with CL52 latency. Registered ECC design targets Supermicro H14DST-FL servers that require 288-pin RDIMMs for full-capacity operation.

Verify motherboard population rules

Check the Supermicro H14DST-FL manual for approved DIMM population order and maximum supported capacity per channel before ordering. The board requires registered RDIMMs rather than unbuffered or SODIMM modules. Ensure BIOS is current for DDR5 6400 recognition.

Registered buffer steadies sustained throughput

Registered architecture reduces electrical load on the memory controller so all four slots remain stable at rated speed during continuous workloads. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. 1.1V operation keeps power draw consistent under load.

Questions about this item

Does the NEMIX RAM DDR5 6400 kit include anything besides the four 32 GB RDIMMs?

The package contains only the four 32 GB DDR5 6400 RDIMMs. No heat spreaders, cables, tools or documentation are included.

When would I choose this 128 GB 4 x 32 GB DDR5 6400 CL52 kit over a smaller capacity?

Choose this kit when your Supermicro H14DST-FL requires the full 128 GB populated across four slots at the rated 6400 MT/s speed with registered ECC.

What does the 6400 MT/s rating mean once the modules are installed in a Supermicro H14DST-FL?

The memory controller will run the kit at 6400 MT/s with CL52 latency at 1.1 V, delivering the full PC5-51200 bandwidth the board supports.
