Supermicro X14QBH+ DDR5-6400 kit

This 256 GB kit contains eight 32 GB DDR5-6400 ECC registered DIMMs built to the exact timing and voltage the Supermicro X14QBH+ memory controller expects. The modules run at 1.10 V with CL52 latency and a 2Rx4 rank layout so the board recognises the full capacity at rated speed.

Servers needing maximum registered ECC capacity

Ideal for administrators populating every slot on a Supermicro X14QBH+ with validated registered ECC memory for production workloads. Not suited for systems that require unbuffered UDIMMs, SODIMM form factors, or lower-density modules than the 32 GB per DIMM this kit provides.

Verify DIMM population rules before ordering

Consult the motherboard manual for approved slot-filling order, maximum supported capacity per channel, and any BIOS version requirements. The kit uses 288-pin RDIMMs only; confirm your platform accepts registered DDR5 and that the 2Rx4 organisation matches its qualified-vendor list.

Questions about this item

Will this kit run at DDR5 6400 in a Supermicro X14QBH+ without manual timing changes?

The kit is spec-matched to the X14QBH+ memory controller with 1.1 V, CL52 and 2Rx4 registered ECC, so it is recognised at full 256 GB capacity and runs at its rated DDR5 6400 speed without extra configuration.

Can I mix these 2Rx4 RDIMMs with 1Rx4 or 2Rx8 modules already installed in the same board?

Registered ECC RDIMMs of different rank or organisation should not be combined in the same channel; the X14QBH+ population rules require identical 2Rx4 modules per channel for stable operation at DDR5 6400.

How do I confirm the system is using all 256 GB at DDR5 6400 with ECC active after installation?

Enter BIOS or use a tool such as dmidecode to verify total memory shows 256 GB, speed reads 6400 MT/s, and ECC status reports enabled for every DIMM slot.
