OWC 8GB DDR3L 1600 CL11 2Rx8 1.35V SODIMM memory upgrade for Lenovo Flex 3 1470 1480 1580

System-specific DDR3L upgrade

This OWC module adds 8GB of DDR3L memory to Lenovo Flex 3 models 1470, 1480 and 1580. It is a single 204-pin SODIMM rated at 1600 MHz with CL11 latency and 1.35 V operation. The unbuffered, non-ECC design matches the factory specification for these laptops. Installation is a straightforward DIY task for most users.

Thermals and power in normal use

Running at the JEDEC-standard 1.35 V keeps power draw low during everyday workloads such as web browsing and document editing. The module has no heat spreader, relying on the laptop's existing airflow to maintain safe temperatures. Silent operation is preserved because no additional cooling hardware is required. ROHS compliance confirms the absence of restricted substances.

Behaviour under sustained load

During prolonged multitasking or large-file handling the 2Rx8 organisation helps maintain consistent throughput at the rated 1600 MHz speed. The memory is tested to meet or exceed OEM specifications, so stability is preserved over extended sessions. Users who need more capacity than a single 8GB module provides will need additional compatible slots. The limited lifetime warranty covers the module for its service life.
