Capacity and purpose
This kit supplies 256GB of DDR5 registered ECC memory in eight 32GB modules for the Lenovo ThinkSystem SR780a V3 rack server. It targets IT teams expanding capacity for virtualisation, databases or other memory-bound workloads on that specific platform.
Registered ECC impact
Registered buffering reduces electrical load on the server memory controller while ECC corrects single-bit errors, together protecting data integrity under sustained load. The 1Rx4 organisation and 1.1V operation follow the platform's DDR5 5600 specification without requiring configuration changes.
Build and connectors
Each module uses a standard 288-pin DDR5 RDIMM form factor without a heat spreader, relying on the server's directed airflow for cooling. The eight-module kit fills matching slots in supported configurations, and the CL46 latency is the rated timing for this speed grade.

이 상품에 대한 질문
Will the 1Rx4 288-pin DDR5 modules need any firmware updates or reseating after long-term use in the SR780a V3?
The registered ECC RDIMMs run at 1.10 V with CL46 latency; no firmware updates are required on the modules themselves, and reseating is only needed if the server is moved or the chassis is opened.
What limit appears first when the 256 GB kit runs sustained workloads at 5600 MT/s?
The 1Rx4 organisation and CL46 timing set the bandwidth ceiling at PC5-44800; sustained throughput will hit that ceiling before thermal or voltage limits are reached.
How much heat and fan noise should I expect from the eight 32 GB sticks running continuously at 5600 MT/s?
Each module operates at 1.1 V without a heat spreader, so power draw per DIMM is low; the server’s existing airflow handles the thermal load without extra fan speed.
