Exact-match DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 256 GB as two 128 GB DDR5-6400 Registered ECC modules built to the PC5-51200 standard. It is designed for servers that require registered DIMMs with on-die error correction and the precise 2Rx4 rank layout the memory controller expects.

Thermals noise and power draw

Operating at 1.1 V without heat spreaders, the modules rely on server chassis airflow for cooling and add minimal power load per DIMM. Registered buffering reduces electrical loading on the memory controller, helping keep system power draw predictable when all slots are populated.

2Rx4 registered ECC constraint

The 2Rx4 registered ECC organisation is the single specification that decides compatibility; only motherboards qualified for this exact rank and buffer type will recognise the full 256 GB capacity at the rated 6400 MT/s speed. Buyers whose platforms require unbuffered UDIMMs or a different rank configuration cannot use this kit.

Spørgsmål om denne vare

How do I install these 288-pin DDR5 RDIMMs in my Supermicro H13SRH, and which population rule is most often missed?

Insert each 128 GB module into the slots listed first in the H13SRH manual, pressing until the ejectors click; the step most often missed is following the exact DIMM sequence so the memory controller recognises the full 256 GB at DDR5-6400.

What maintenance or replacement will this 2Rx4 registered ECC kit need over its service life?

No periodic maintenance is required; the modules carry a lifetime replacement warranty, so a single-bit error corrected by ECC or a rare hardware fault is resolved by swapping the affected RDIMM without opening a support ticket.

What limit appears first when the kit runs at 6400 MT/s under sustained load?

The CL52 latency at 1.1 V is the first constraint; registered buffering keeps every slot stable at full capacity, but the timing budget at DDR5-6400 governs maximum sustained throughput before the controller must throttle.
