Exact-fit server upgrade

This NEMIX RAM kit delivers 64 GB across two 32 GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro X14QBH+ motherboard. The modules run at 1.1 V with CL52 timing and a 2Rx4 organisation that matches the board's memory-controller expectations.

Replacing slower or smaller DIMMs

Swap out lower-capacity or slower-speed Registered ECC RDIMMs when your workload needs the full 64 GB at the rated 6400 MT/s data rate. The jump is worth it when every slot must be populated at full speed without down-clocking.

Verify before ordering

Confirm the motherboard manual lists 32 GB dual-rank Registered DIMMs in the approved population order for your CPU configuration. Ensure the system accepts 1.1 V DDR5 RDIMMs and that no UDIMM or SODIMM requirement exists.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro X14QBH+ motherboard slots?

Yes, the 288-pin RDIMM form factor matches the slots on the Supermicro X14QBH+ motherboard and is not a UDIMM or SODIMM.

What is the correct installation order for the two 32GB modules on the Supermicro X14QBH+?

Consult the motherboard manual for the approved DIMM population sequence before installing the 2Rx4 registered modules.

Will the Samsung, Micron or Hynix chips on these modules require any firmware updates later?

No firmware updates are needed for the memory chips; the modules run at the rated DDR5-6400 CL52 1.1V settings once installed.
