512GB DDR5 ECC RDIMM Kit for Lenovo SR680a V3

This 512GB kit contains eight 64GB DDR5 5600 registered DIMMs built for the Lenovo ThinkSystem SR680a V3 rack server. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 1.1V with CL46 latency and a 4Rx4 organisation.

Replaces Smaller or Slower DDR5 Kits in the SR680a

Upgrading from lower-capacity or lower-speed DDR5 kits is worthwhile when virtualisation density, in-memory databases or large-scale analytics demand more bandwidth and capacity per socket. The 5600 MT/s rate and 512GB total capacity raise the ceiling for concurrent VMs and dataset size.

Fills Eight DDR5 RDIMM Slots at 1.1V

The kit occupies eight 288-pin DDR5 RDIMM slots and draws 1.1V, leaving no empty DIMM positions for future expansion within this population. Builders needing additional memory beyond 512GB must plan for higher-density modules or a different server chassis.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the Lenovo ThinkSystem SR680a V3 server slots?

Yes, the 8 x 64 GB modules are built for the SR680a V3 and use the standard 288-pin DDR5 RDIMM form factor required by that platform.

What is the correct order to populate the eight 64 GB modules in the SR680a V3?

Follow the server manual’s population sequence — typically fill one DIMM per channel across all memory controllers before adding a second rank to any channel.

When should the 4Rx4 ECC RDIMMs be replaced if correctable error counts start rising?

Replace modules once the system logs show a sustained increase in correctable ECC events, as the 4Rx4 organisation offers no spare ranks for online sparing.
