Lenovo SR780a V3 Memory Kit

This 2TB kit provides 16 registered DDR5 modules at 128GB each for the ThinkSystem SR780a V3 server. It is built for IT teams that need maximum ECC capacity in a single qualified configuration.

Sustained Load Behaviour

Registered buffering and on-die ECC keep data integrity stable during continuous enterprise workloads. The 1.10V operating voltage helps maintain thermal consistency across all 16 modules under prolonged utilisation.

DDR5 5600 Interface Limits

The PC5-44800 standard sets the peak transfer rate at 5600 MT/s with CL46 latency. Four-rank 4Rx4 organisation increases density per slot but constrains maximum operating frequency compared to lower-rank alternatives.

Questions sur cet article

How much power does the 1.1V DDR5 kit draw when the SR780a V3 runs continuously?

Each module operates at 1.1V; total draw depends on how many of the 16 slots the server populates and the workload.

What must the server already have to accept this 16×128GB RDIMM kit?

A Lenovo ThinkSystem SR780a V3 with 16 free 288-pin DDR5 RDIMM slots and a BIOS that supports 4Rx4 registered ECC modules.

Will these 5600 CL46 modules run with slower DDR5 DIMMs I keep in the same chassis?

The server will clock all installed DDR5 to the lowest common speed and latency; mixing ranks or speeds is not recommended by Lenovo.
