Server-specific DDR3 kit

This 32 GB kit contains four 8 GB DDR3 1600 modules built for Lenovo ThinkServer TS140 and TS440 systems. The memory is ECC unbuffered and operates at 1.5 V with CL11 timing. It is intended for server workloads only and not for desktop platforms.

Verify server model and voltage

Confirm the target machine is a ThinkServer TS140 or TS440 with part numbers 70ALxxx, 70AMxxx, 70ANxxx or 70AQxxx. The modules require 1.5 V DDR3 slots; the supplier notes a 1.35 V DDR3L variant exists, so match the voltage to the system specification. Four DIMM sockets must be free for the full kit.

Unbuffered ECC modules without heat spreaders

Each stick is a 240-pin 2Rx8 unregistered DIMM using major-brand chips and no heat spreader. The low-profile design fits standard server DIMM slots and allows dense four-module population. ECC protection helps maintain data integrity in always-on server environments.

Questions about this item

What comes in the box and do I need anything else?

The kit includes four 8GB DDR3 ECC unbuffered DIMMs (32GB total). No extra parts are required for installation.

Should I choose this 4x8GB kit or a different capacity for my ThinkServer TS440?

The TS440 has four DIMM slots and supports up to 32GB, so this 4x8GB kit fills every slot and reaches the maximum capacity.

What does DDR3-1600 CL11 mean for actual server performance?

The modules run at 1600MHz with 11-11-11 latency at 1.5V, providing ECC error correction for stable operation in the TS440.
