NEMIX RAM 1TB DDR4 ECC RDIMM Kit

This 1TB kit contains eight 128GB DDR4 3200MHz PC4-25600 registered ECC RDIMMs. It is built for the Supermicro X12QCH+ motherboard and suits administrators who need maximum memory capacity on that specific platform. The modules run at 1.2V with CL22 latency and a 2Rx4 rank configuration.

Verify Supermicro X12QCH+ DIMM Population Rules

Check your motherboard manual for supported capacities per slot, approved population order, and any BIOS version requirements before ordering. The board requires 288-pin registered RDIMMs; unbuffered UDIMMs or SODIMMs will not work. Confirm the server can address the full 1TB across all populated channels.

Replaces Smaller DDR4 RDIMM Sets on X12QCH+

The upgrade is worthwhile when your workloads exceed the capacity of a smaller registered ECC kit and the motherboard firmware supports full 128GB-per-slot population. It is not for systems that only accept UDIMMs, for builds needing SODIMM form factors, or for platforms limited to lower maximum memory per channel.

Questions about this item

Does the 1TB kit ship as eight 128 GB modules or do I need to buy any sticks separately?

The kit contains eight 128 GB DDR4 RDIMMs for a total of 1 TB; no additional modules are required.

Why is the kit specified as 2Rx4 CL22 rather than a different rank or latency?

The Supermicro X12QCH+ memory controller expects 2Rx4 organization and CL22 timing at 3200 MT/s; using this exact specification ensures full-capacity recognition and rated-speed operation.

What does the 3200 MT/s rating mean once all eight slots are populated on this motherboard?

With registered ECC modules the memory controller can drive every slot at the full 3200 MT/s data rate, delivering the rated PC4-25600 bandwidth across the entire 1 TB configuration.
