Frequently Asked Questions

This is a SODIMM (Small Outline DIMM) module designed for laptops, mini PCs, and other compact systems that accept PC3L-12800 DDR3L memory.
The "L" designates low-voltage operation at 1.35V instead of the standard 1.5V for DDR3, which means lower power consumption and less heat — though most PC3L modules also work at 1.5V in systems that require it.
Generally yes, you can mix a 4GB module with a different size in a second slot, but for optimal performance both modules should match in speed and voltage. Check your system's documentation for specific compatibility guidance.
Check your laptop's service manual or manufacturer website for supported memory types. You need a system that accepts DDR3L SODIMM modules at PC3L-12800 (1600 MHz) speed.
