Server memory kit

This 512GB kit contains sixteen 32GB DDR5 5600 ECC registered DIMMs built for the Lenovo ThinkSystem SR680a V3 rack server. Each module runs at 1.1V with a CL46 latency and uses a 1Rx4 organisation. The registered design and error-correcting code target enterprise workloads that require data integrity across all populated slots.

Sustained operation

Registered buffering reduces electrical load on the memory controller when all sixteen slots are filled, helping the platform maintain the rated 5600 MT/s transfer rate under continuous demand. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 1.1V operating voltage keeps power draw predictable across the full kit.

Build and connectors

Modules use the standard 288-pin DDR5 RDIMM form factor without heat spreaders, relying on server chassis airflow for cooling. Major-brand Samsung, Micron or Hynix DRAM components are assembled to meet Lenovo qualification requirements. The kit is intended exclusively for the validated platform; other systems will not accept the registered ECC pinout or firmware profile.

Questions sur cet article

How much power does the 1.10 V DDR5 5600 kit draw when the Lenovo ThinkSystem SR680a V3 runs all day?

Each 32 GB module operates at 1.10 V, so the 16-module kit runs at the standard DDR5 voltage; actual watts depend on the server workload and memory controller.

What must the Lenovo ThinkSystem SR680a V3 already have for this 512 GB kit to work?

The server needs 16 free 288-pin DDR5 RDIMM slots and a BIOS that supports 1Rx4 ECC registered modules at 5600 MT/s.

Will the 1Rx4 CL46 registered modules run alongside existing 2Rx8 DDR5 RDIMMs in the same server?

Mixing ranks is possible if the platform's memory controller allows it; the SR680a V3 manual specifies which rank combinations are supported per channel.
