System-specific DDR3L upgrade

This 4GB SODIMM is built for Lenovo E50-70, E50-80, E51-80, Edge 2-1580, G400, G40-30 and G40-45 notebooks. It targets owners of those models who need a straightforward capacity increase without compatibility guesswork. The module follows JEDEC and ROHS standards for a warranty-safe installation.

Single-module simplicity

The package contains one 204-pin stick rated at 1600 MT/s with CL11 timing and 1.35 V operation. No heat spreader, ECC or registered circuitry is present, keeping the form factor identical to the factory memory. Installing it is a typical DIY task that requires no extra tools or software.

Everyday headroom

Four gigabytes adds comfortable room for web browsing, office suites and light multitasking on supported Lenovo systems. Heavier workloads such as video editing, virtual machines or large data sets will exceed this capacity quickly. Buyers who need more memory should look for higher-density kits instead.

Questions about this item

Will the 204-pin SODIMM need any firmware updates or heat spreader replacement during its service life?

No firmware updates are required for this JEDEC-standard DDR3L module, and it ships without a heat spreader so none will need replacing.

What electrical limit appears first when the 1.35 V DDR3L 1600 module runs continuously at full load?

The 1.35 V operating voltage is the fixed electrical ceiling; sustained full-load operation stays within that JEDEC-defined limit.

How much heat and fan noise does the unbuffered 1Rx8 4 GB stick add during all-day operation?

The low-voltage 1.35 V DDR3L design produces minimal extra heat, so system fan speeds and acoustic levels remain essentially unchanged.
