Server-grade memory kit

This 128GB kit delivers four 32GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. It targets administrators upgrading the Supermicro X14SDW-36CE-SP9F motherboard where registered ECC memory is mandatory for full-capacity population.

Registered ECC architecture

The 2Rx4 registered design buffers address and command signals so the memory controller remains stable with all slots filled. On-die ECC detects and corrects single-bit errors automatically, preventing silent data corruption that would otherwise crash production workloads.

288-pin RDIMM form factor

Modules use the standard 288-pin DDR5 RDIMM keying required by the target board; they will not fit UDIMM or SODIMM slots. No heat spreader is fitted, so airflow across the bare PCB must be provided by the server chassis fans.

Questions about this item

Will the four 32 GB DDR5 6400 CL52 RDIMMs need any firmware updates or periodic replacement?

No firmware updates are required; the modules are designed for continuous server operation and carry a lifetime replacement warranty.

What limits sustained throughput on the Supermicro X14SDW-36CE-SP9F when all four slots are populated?

The memory controller runs the kit at its rated DDR5 6400 speed with CL52 timings when fully populated.

How much heat and power does the 128 GB kit draw at 1.1 V during all-day workloads?

Each module operates at 1.1 V without a heat spreader; registered buffering reduces electrical load on the controller.
