Capacity and Configuration

This 1 TB kit contains sixteen 64 GB DDR5 modules for a total of 1 TB of registered ECC memory. It is built for the Lenovo ThinkSystem SR780a V3 rack server and similar platforms that require 288-pin RDIMM modules.

Speed and Latency

Rated at DDR5 5600 with CL46 timing, the kit delivers PC5-44800 bandwidth for demanding server workloads. The 2Rx4 organisation and 1.1 V operating voltage keep power draw low while maintaining stability under sustained load.

Build and Compatibility

Modules use major OEM Samsung, Micron or Hynix chips without heat spreaders, relying on server chassis airflow for cooling. Registered buffering and ECC support ensure data integrity for mission-critical applications in compatible Lenovo systems.

Questions about this item

Will the 5600 MT/s DDR5 RDIMMs run at their rated speed alongside other DDR5 modules I might keep?

All 16 modules in this kit are DDR5 5600 CL46 2Rx4 1.1V ECC RDIMMs; mixing modules with different speeds, latencies, ranks or voltages will cause the memory controller to run at the lowest common settings.

How can I verify the 1 TB kit is operating as intended after installation?

Check the server BIOS or management console to confirm all 16 modules are detected at 5600 MT/s with ECC active and the registered RDIMM configuration recognised.

What is included in the box and what must be purchased separately?

The package contains the 16 x 64 GB DDR5 5600 CL46 2Rx4 1.1V ECC RDIMM modules; no heat spreaders, cables or additional hardware are supplied.
