Lenovo SR780a V3 DDR5 upgrade kit

This 128 GB kit contains four 32 GB DDR5 5600 ECC registered DIMMs built for the Lenovo ThinkSystem SR780a V3 rack server. It targets IT teams who need to expand memory capacity in that specific platform without mixing module types.

Verify DDR5 RDIMM slots and population rules

Before ordering, confirm the server has free 288-pin DDR5 RDIMM slots and check the system manual for the approved population order. The modules run at 1.1 V with CL46 latency and are single-rank 1Rx4, so the memory controller must support that rank configuration.

Registered ECC modules without heat spreaders

Each stick is a bare 288-pin registered DIMM using major-brand DRAM chips and includes on-die ECC for data integrity. The lack of heat spreaders keeps the profile low for dense server chassis, while the registered buffer reduces electrical load on the memory bus during sustained workloads.

Highlights

  • 128 GB total capacity across four 32 GB modules
  • DDR5 5600 speed rated at PC5-44800 bandwidth
  • ECC registered design detects and corrects data errors
  • Low 1.1 V operating voltage reduces power draw
  • Validated for Lenovo ThinkSystem SR780a V3 rack servers

Questions about this item

What does the 128 GB kit contain and is anything else required for installation?

The kit includes four 32 GB DDR5 5600 CL46 1.1 V ECC registered DIMMs. No extra parts are needed; install directly into the server's 288-pin slots.

How do I decide between the 5600 MT/s CL46 kit and other speed or latency options for the SR780a V3?

Choose this 5600 MT/s CL46 kit when the server's memory controller and BIOS are qualified for DDR5-5600 operation; it matches the platform's validated speed and latency.

What does the 5600 MT/s rating deliver once the modules are running in the SR780a V3?

The modules operate at 5600 MT/s with CL46 timing at 1.1 V, providing the bandwidth and error-correction the server's memory subsystem is designed for.
