Computer Memory Solutions CM5126412800SOSRL 4GB DDR3L 1600MHz SODIMM for Lenovo Thinkpad E455 memory upgrade

Compatible ThinkPad E455 SODIMM

This 4 GB DDR3L module is built for the Lenovo ThinkPad E455 and fits its 204-pin slots. It runs at 1600 MHz with a CAS latency of 11 and operates at 1.35 V. The unbuffered, non-ECC design matches the notebook’s standard memory specification.

Upgrade from lower capacity or slower DDR3

The stick adds 4 GB in a single rank 1Rx8 configuration, raising total memory toward the system’s 16 GB ceiling across two sockets. It replaces any slower DDR3 SODIMM or fills an empty slot when the existing module already runs at PC3L 12800. The jump is worthwhile when multitasking or browser tabs push the current amount past its limit.

Steady operation without a heat spreader

Major-brand chips run at the rated 11-11-11 timings under continuous load because the low 1.35 V keeps thermals modest in the confined laptop chassis. No spreader means the module relies on the ThinkPad’s existing airflow, which is sufficient for the JEDEC-standard power envelope. Stability holds during long compile jobs or video playback sessions.
