Server Memory Kit

This 1TB DDR5 kit contains sixteen 64GB registered DIMMs built for the Lenovo ThinkSystem SR780a V3 rack server. It targets administrators who need maximum registered ECC capacity in a single validated package.

Compatibility Check

Confirm the server has sixteen free 288-pin DDR5 RDIMM slots and that the memory controller supports 4Rx4 modules at 5600 MT/s. Verify the BIOS revision matches Lenovo's qualified vendor list for this part number.

Build Integration

The modules operate at 1.1V and run without heat spreaders, so airflow across the DIMM rows must meet Lenovo's thermal guidelines. Populating all slots delivers 1TB of registered ECC capacity while leaving no additional DIMM positions open.
