Product Identity

Computer Memory Solutions CM5126412800SOSRL is a 4GB DDR3L 1600 SO-DIMM built for the Lenovo ThinkPad T540P notebook. It runs at 1.35V with CL11 timing and uses a 204-pin unbuffered, non-ECC layout. The single-rank 1Rx8 module is supplied as a one-piece upgrade kit.

Who It Suits

Owners of a ThinkPad T540P looking for a straightforward 4GB memory increase will find this module validated for their system. Buyers who want more storage capacity, a higher total memory ceiling than 16GB, or a dual-channel kit with matched sticks should look at something else.

Deciding Specification

The module operates at DDR3L 1600 (PC3L 12800) with a CAS latency of 11 and 1.35V voltage. This exact speed, voltage, and timing combination determines whether the part will function correctly in the T540P platform.

Questions about this item

How much power does this 1.35 V DDR3L module draw during all-day workloads?

It runs at 1.35 V, the standard low-voltage level for DDR3L SO-DIMMs, so power draw stays low even under continuous use.

What must my ThinkPad T540p already have for this 204-pin SO-DIMM to install?

A free DDR3L SO-DIMM slot; the T540p provides two slots and supports up to 16 GB total.

Will this CL11 1600 MHz module run at its rated speed alongside an older DDR3L stick already in the T540p?

The system will clock both modules to the lowest common speed and tightest shared timings; the new stick is rated 1600 MHz CL11.
