System-specific DDR3L upgrade

This 4 GB DDR3L SODIMM is built for Lenovo Flex 3 models 1470, 1480 and 1580. It plugs into the 204-pin slot and runs at 1.35 V without ECC or buffering. The module targets owners of those notebooks who need a straightforward memory increase.

JEDEC DDR3L 1600 interface limits

The stick conforms to the PC3L-12800 standard with CL11 timing and a single 1Rx8 rank. Speed and voltage are fixed by the specification, so the module cannot exceed the platform's native DDR3L 1600 ceiling. Systems that require registered memory or a different voltage will not accept it.

4 GB capacity and headroom

A single 4 GB module adds modest multitasking room for everyday workloads and light media tasks. It fills one slot and leaves any second slot free for a matching stick if the chassis supports dual-channel operation. Workloads that demand more than 4 GB total will still hit a hard limit.

Questions about this item

Should I choose the 4GB DDR3L 1600 module or look for a different capacity for my Lenovo Flex 3?

This module provides a single 4GB DDR3L 1600 stick. If your Flex 3 1470, 1480 or 1580 has a free SODIMM slot, adding this 4GB increases total memory by that amount. For a larger increase you would need a higher-capacity module or a matched pair.

What does the PC3L-12800 rating mean for everyday performance on a Flex 3?

PC3L-12800 indicates a peak transfer rate of 12800 MB/s at 1600 MT/s. In the Flex 3 this translates to faster application loading, smoother multitasking with several browser tabs or office documents open, and reduced reliance on the swap file.

Will the 204-pin DDR3L 1.35V interface work without changes in my Flex 3 1480?

Yes. The 204-pin SODIMM form factor, DDR3L signalling and 1.35 V operation match the factory memory specification for the Flex 3 1470, 1480 and 1580, so the module installs directly and runs at the rated CL11 timings.
