128GB DDR5 ECC RDIMM Kit for Lenovo SR780a V3

This 128GB kit contains two 64GB DDR5 5600 registered DIMMs with ECC and a CAS latency of 46. It is built for the Lenovo ThinkSystem SR780a V3 rack server and runs at 1.1V. The 4Rx4 organisation suits high-density memory configurations in enterprise environments.

Verify DDR5 RDIMM Slots and 5600 Support

Confirm that your SR780a V3 has free 288-pin DDR5 RDIMM slots and that the platform firmware enables 5600 MT/s operation with 4Rx4 modules. Registered ECC memory must be paired with a compatible server chipset; mixing with unbuffered or non-ECC DIMMs will prevent boot.

Fits SR780a V3 Memory Channels

The two modules populate a matched pair of channels, leaving remaining slots open for future expansion up to the platform limit. Registered buffering reduces electrical load on the memory controller, freeing headroom for additional ranks. No heat spreaders are fitted, so ensure chassis airflow meets the server specification.

商品問答

Does the 128GB kit include two 64GB DDR5 5600 ECC RDIMM modules or do I need to buy them separately?

The kit ships with two 64GB DDR5 5600 ECC RDIMM modules totalling 128GB, so no extra modules are required.

Should I choose the 4Rx4 CL46 version or a different rank and latency for the Lenovo SR780a V3?

This kit is built as 4Rx4 CL46 at 1.1V, matching the server’s qualified configuration for registered ECC memory.

What does the 5600MHz PC5-44800 rating mean when the modules are installed in the SR780a V3?

The modules will run at DDR5 5600 transfer rate with CL46 latency, delivering the rated PC5-44800 bandwidth in the supported server slots.
