Server memory kit for Supermicro X14QBH+

This 512GB kit contains 16 modules of 32GB DDR5 RDIMM memory. It is built for servers that require registered ECC modules and is validated for the Supermicro X14QBH+ motherboard. The kit delivers the exact rank, voltage and timing the platform expects.

DDR5 6400 registered ECC limits

The modules operate at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V. Registered buffering allows every slot to be populated at full capacity while ECC corrects single-bit errors. The 288-pin RDIMM form factor is not compatible with UDIMM or SODIMM slots.

Verify motherboard population rules

Check your system manual for supported capacities, approved DIMM population order and installation steps before ordering. This kit requires a platform that accepts 16 registered DDR5 modules at the specified speed and voltage.

Questions about this item

Should I choose the 16-module 512GB kit or a smaller capacity for my Supermicro X14QBH+?

The 16 x 32GB kit fills every DDR5 slot on the X14QBH+ and delivers the full 512GB the board supports; choose it when you need maximum capacity, otherwise pick a smaller kit that matches your workload.

What does the DDR5-6400 rating mean once the modules are installed in the server?

The memory controller will run the kit at 6400 MT/s with CL52 latency at 1.1V, giving the full PC5-51200 bandwidth the X14QBH+ is designed for.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered buffer lets all 16 slots run at 6400 MT/s without signal degradation, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
