ECC Registered DDR3L Kit for Lenovo Servers

This 32GB kit contains four 8GB DDR3L 1600 CL11 modules built to JEDEC 1.35V spec. Each stick is a 240-pin 1Rx4 registered DIMM with ECC, designed for Lenovo System x3650 M4, x3650 M4 BD, x3650 M4 HD, x3750 M4 and x3755 M3 platforms.

Verify Registered DIMM Slots and Voltage

Confirm the target system accepts registered ECC DDR3L at 1.35V and has four free 240-pin slots. Unbuffered or standard desktop DDR3 will not work in these channels, and mixing registered with unbuffered modules prevents boot.

Steady Throughput Under Continuous Server Load

Registered buffering and on-die ECC maintain data integrity during sustained multi-threaded workloads. The 1.35V DDR3L voltage reduces thermal pressure compared to 1.5V parts, helping the kit hold rated 1600 CL11 timings over long uptime cycles.
