Lenovo ThinkSystem SR250 V3 64GB DDR5 Kit

This 64GB kit contains two 32GB DDR5 4800 ECC UDIMM modules built for the Lenovo ThinkSystem SR250 V3 rack server. It targets administrators who need to expand memory capacity in that specific platform with validated unbuffered ECC memory. The modules operate at 1.1V with CL40 latency.

Installation and common issues

The 288-pin UDIMM form factor fits standard DDR5 slots and installs in minutes by seating each module until the retention clips lock. Because the kit is unbuffered ECC, the server BIOS must support ECC on unbuffered DIMMs; otherwise the system may boot without error correction or fail to post. Mixing ranks or speeds can also cause instability.

Pre-order compatibility checks

Confirm the ThinkSystem SR250 V3 motherboard populates DDR5 UDIMM slots and accepts 2Rx8 32GB modules at 4800 MT/s. Verify the BIOS version supports 64GB total capacity with unbuffered ECC and that no registered or load-reduced DIMMs are required. Ensure the operating system and workloads can use ECC memory.
