System-specific DDR5 RDIMM for Supermicro X14QBH+

This 32GB NEMIX RAM module is built as a direct upgrade for the Supermicro X14QBH+ motherboard. It uses the DDR5 6400 (PC5-51200) standard with CL52 latency and 1.10V operation. The registered ECC design matches the board's memory controller requirements for full-capacity recognition.

Suited for populated server slots.

This module fits administrators expanding or repairing X14QBH+ systems that require registered ECC RDIMMs. It will not work in desktop boards or laptops that accept only unbuffered non-ECC UDIMMs or SODIMMs. Builders needing consumer memory should look elsewhere.

Registered ECC with 2Rx4 organisation

The single specification that decides fitment is the registered ECC RDIMM format with 2Rx4 rank configuration. This exact organisation allows the memory controller to address every slot at the rated DDR5 6400 speed without signal degradation.

Questions about this item

What is the CAS latency of this DDR5 6400 module under sustained load?

The module runs at CL52, so the CAS latency remains 52 cycles at its rated DDR5 6400 speed.

Does this registered ECC RDIMM generate noticeable heat or fan noise during 24-hour operation?

It operates at 1.1 V with no heat spreader, so thermal output is low and it adds no fan noise of its own.

Which motherboard and DIMM type must already be installed for this kit to function?

A Supermicro X14QBH+ motherboard with 288-pin DDR5 RDIMM slots is required.
