  • Low 1.10 V operation reduces power draw
  • Validated for Supermicro X14SBW-TF systems

Capacity and configuration

This kit delivers 512GB of DDR5 capacity across four 128GB registered DIMMs, each organised as 4Rx4 with ECC. It targets administrators and integrators who need maximum memory density in Supermicro X14SBW-TF platforms for virtualisation, database or AI workloads.

Build integration

The modules use the standard 288-pin DDR5 RDIMM form factor and operate at 1.1V, drawing power directly from the motherboard slots. Registered signalling and on-die ECC reduce electrical load on the memory controller, freeing headroom for sustained throughput in heavily populated configurations.

Upgrade context

The kit replaces lower-capacity or non-ECC DDR5 DIMMs when the workload demands 512GB of registered memory with CL52 latency at 6400MHz. The jump is worth it when the application scales beyond the limits of smaller kits and the platform supports the 4Rx4 organisation.

Perguntas sobre este artigo

Does the CL52 latency limit throughput during sustained workloads?

CL52 is the rated CAS latency at 6400 MHz; sustained throughput depends on the server memory controller and cooling.

How much heat does a 512 GB kit generate when running all day?

Each 128 GB module operates at 1.1 V without a heat spreader; total power draw scales with load and chassis airflow.

Which motherboard slots are required for the 4Rx4 registered DIMMs?

The kit needs a Supermicro X14SBW-TF or compatible DDR5 RDIMM platform with 288-pin slots supporting 4Rx4 registration.
