Lenovo SR780a V3 Compatible DDR5 RDIMM

This 64GB registered DIMM is built for the Lenovo ThinkSystem SR780a V3 rack server. It targets IT teams upgrading memory capacity in that specific platform. The module uses DDR5 technology with ECC and registered buffering for enterprise stability.

CL46 latency at DDR5 5600

The single specification that determines fit is the CAS latency of CL46 running at DDR5 5600 (PC5-44800). This timing must match the server memory controller configuration for the module to operate at rated speed. A different latency value would prevent correct operation.

64GB capacity per module

One module provides 64GB of registered ECC memory using a 2Rx4 organisation at 1.10V. It handles large virtualisation workloads and in-memory databases comfortably. Capacity runs out when the server reaches its maximum DIMM slot limit or total memory ceiling.

Questions about this item

How does the CL46 latency affect real-world server performance?

CL46 is the CAS latency at 5600 MT/s; the module runs at DDR5 5600 (PC5-44800) with 1.10 V, delivering standard JEDEC timing for registered ECC workloads.

What does the PC5-44800 rating actually limit in this system?

PC5-44800 equals 5600 MT/s DDR5 bandwidth; the registered ECC RDIMM operates at that speed with 2Rx4 organisation on the Lenovo ThinkSystem SR780a V3.

Will this 288-pin RDIMM fit the Lenovo SR780a V3 memory slots?

Yes — it is a 288-pin DDR5 ECC RDIMM built for the Lenovo ThinkSystem SR780a V3 rack server and installs in the standard DIMM sockets.
