2 TB DDR5 6400 ECC RDIMM kit

This 2 TB kit contains sixteen 128 GB DDR5 6400 RDIMMs built for the Supermicro X14QBH+ motherboard. Each module is a 288-pin registered DIMM with ECC and a 4Rx4 organisation. The kit is designed for servers that need maximum registered memory capacity in every slot.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller so all sixteen slots can run continuously at 6400 MT/s without signal degradation. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 1.1 V operating voltage keeps power draw stable under full population.

Verify DIMM population rules before ordering

The X14QBH+ motherboard has specific slot-filling sequences and maximum capacity limits per channel that must be followed for the kit to be recognised. Consult the board manual for the approved population order and any BIOS version requirements. Ensure the platform supports 4Rx4 registered modules at the full 2 TB density.

Questions about this item

With 16 modules drawing 1.1 V each, how much heat and power should I expect when the server runs continuously?

Each 128 GB RDIMM operates at 1.10 V with a CL52 latency; the registered buffer reduces electrical load on the memory controller so all 16 slots can stay populated at DDR5 6400 without extra voltage, keeping thermals predictable in a properly cooled chassis.

What motherboard and firmware do I need so the 2 TB kit is recognised at full speed?

The kit is validated for the Supermicro X14QBH+ motherboard running DDR5 6400 (PC5 51200); the board must support 288-pin registered ECC RDIMMs and have a BIOS version that enables 4Rx4 population across all 16 slots.

Can I mix these 4Rx4 CL52 sticks with lower-rank DDR5 modules already installed in the same system?

Mixing ranks or capacities is not supported — the X14QBH+ requires identical 4Rx4 registered ECC RDIMMs in every populated slot to run the full 2 TB at the rated 6400 MT/s with ECC active.
