Lenovo SR680a V3 DDR5 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5 registered DIMMs built for the Lenovo ThinkSystem SR680a V3 rack server. Each module runs at 5600 MT/s with CL46 latency and 1.1 V operation. The registered design with on-die ECC targets enterprise workloads that require data integrity.

1Rx4 organisation and major OEM DRAM

The 1Rx4 rank structure uses Samsung, Micron or Hynix die to deliver high density per module. Registered buffering reduces electrical load on the server memory controller. ECC circuitry corrects single-bit errors without software intervention. No heat spreader is fitted, so airflow in the chassis manages thermals.

288-pin DDR5 form factor for dense servers

The standard 288-pin DDR5 RDIMM connector fits the SR680a V3 memory slots directly. Modules install in minutes by seating them until the retention clips engage. Builders who need more than 64 GB per channel or who require non-registered UDIMMs cannot use this kit.

Questions about this item

Will the CL46 latency 1Rx4 DDR5 modules need any firmware updates or replacement under continuous server workloads?

The 1Rx4 DDR5 5600 CL46 registered ECC modules are validated for the Lenovo ThinkSystem SR680a V3 and run at the standard 1.1 V; no firmware updates are required and the modules carry a lifetime replacement warranty.

What limit appears first when the 64 GB kit runs at DDR5 5600 continuously in the SR680a V3?

The CL46 CAS latency at 5600 MT/s is the primary timing constraint; the registered buffer and ECC overhead define the sustained throughput ceiling before any thermal or power limit is reached.

How much heat and power does the 2 × 32 GB DDR5 5600 kit generate during all-day operation without heat spreaders?

Each module operates at 1.1 V with no heat spreader; the registered DDR5 design keeps power draw and thermals low for continuous server duty.
