System-Specific 8GB DDR3L SODIMM

This Computer Memory Solutions module delivers 8 GB of DDR3L memory at 1600 MHz with CL11 timing and 1.35 V operation. The 204-pin unbuffered SODIMM uses a 2Rx8 rank configuration and Major Brand Chipset components. It is validated for the Lenovo ThinkPad E550 and supplied as a single stick.

Suits ThinkPad E550 owners adding

Buyers who need ECC error correction, registered buffering, a heat spreader, or a dual-stick kit should look elsewhere. The module is non-ECC, unbuffered, and sold as a single 8 GB piece without a spreader. Systems requiring a different pin count, voltage, or form factor cannot use this part.

Deciding spec: DDR3L 1600 MHz at 1.35 V in 204-pin

Only laptops that accept DDR3L SODIMMs at this speed and voltage will recognise the module. The E550 supports up to 16 GB across two sockets, so this 8 GB stick fits one slot and leaves room for a second if desired.

Questions about this item

Will the 204-pin DDR3L module need any cleaning or contact maintenance over time?

The module has no moving parts or heat spreader, so routine cleaning is not required; simply ensure the slot is dust-free when installing.

What limits sustained throughput on this CL11 1600MHz stick?

The CAS latency of 11 cycles at 1600 MHz sets the primary timing ceiling for continuous read and write operations.

How much heat or power does the 1.35V unbuffered SODIMM produce during all-day use?

Operating at 1.35 volts without a heat spreader, the module runs cool and draws minimal power under constant load.
