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.

Questions about this item

Will this 204-pin DDR3L SODIMM fit the memory slots in a ThinkPad E455?

Yes, the module is a 204-pin DDR3L SODIMM rated at 1600 MHz and 1.35 V, which matches the ThinkPad E455 memory specification.

What is the correct way to seat the stick so it locks properly?

Slide the module into the slot until the gold edge contacts are fully hidden, then press down evenly until both side clips snap into the notches.

Does this 4 GB stick need any firmware updates or paired modules to keep working reliably?

No firmware is required; the stick is unbuffered non-ECC CL11 1Rx8 and will run indefinitely as a single module or paired with a second stick up to the 16 GB system maximum.
