Overall Review: Read your device manual and check if your device can support this before you buy it. These chips max out the rate of mobile i7s (1600MHz) so they are going to be the best chip you can find for your laptop.

The other reviewer that could not get this to work simply did not read the manual or research how much memory their laptop could support. I have experienced no issues using ~28GB of RAM in Windows on 2x16GB of these modules with my Dell Latitude E7250 for about a week now. This will NOT work with Intel 4xxx line of processors unless they are stated to support 2x16GB explicitly. That being said there is no guarantee this will work with your BIOS. This particular chip happens to use timings that seem to work with Broadwell. Neither Intel or the manufacturer of the laptop will state this or support this configuration - mobile Broadwell does not officially support more than 2x8GB due to JEDEC timing noncompliance issues. item 7 Crucial DDR3L 16GB 1600MHz SODIMM PC3L-12800 204-Pin 1.35V 2Rx8 Notebook Memory Crucial DDR3L. Pros: You can use 2 of these 16GB modules in an Intel Broadwell (5xxx) based laptop.
