Server Memory Kit

This 1TB kit contains eight 128GB DDR5 RDIMM modules rated at 6400MT/s with CL52 latency and 1.1V operation. It is built for the Supermicro X14QBH+ motherboard and other platforms that require registered ECC memory in a 288-pin form factor.

Registered ECC Benefits

The 4Rx4 registered design buffers address and command signals so the memory controller can drive all slots at full population. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads.

Pre-Purchase Checks

Verify your motherboard manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before ordering. This kit is not compatible with systems that accept only unbuffered UDIMM or SODIMM modules.

Questions about this item

Will the 4Rx4 registered DIMMs require any firmware or BIOS updates on the Supermicro X14QBH+ to run at DDR5 6400 CL52?

The kit is an exact-match upgrade specified for the X14QBH+ at DDR5 6400 PC5-51200, 4Rx4 registered ECC, 1.1 V, CL52, 288-pin. The memory controller recognises the rank, voltage and timing at full capacity and rated speed without extra steps.

What is the first limit reached when all eight slots stay fully populated at DDR5 6400 continuously?

Registered (buffered) architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

How much heat and power do the 128 GB modules produce at 1.1 V with no heat spreaders during all-day operation?

Each module operates at 1.1 V DDR5 standard voltage; registered buffering reduces electrical load on the controller. With no heat spreaders fitted, airflow across the 288-pin RDIMMs handles thermal dissipation in a properly cooled server chassis.
