1.5v instead of 1.35v ram, not supported by all laptops.
12 July 2014
Summary: &&&&&&&&&&&&&&&&&&&&&&&&The ram's voltage is rated @ 1.5v, and only some laptop supports 1.5v ram voltage. It's not mentioned anywhere in item description. Tested works with: Lenovo S400 laptop (core i3), Apple Macbook Pro (Late 2012 model, up to 16gb) DOES NOT WORK WITH: Lenovo U430 ultrabook (core i7) So make sure your laptop can support 1.5v ram voltage before buying this, or just buy a 1.35v rated ram instead to avoid trouble once and for all.
Summary: targetas this ram works perfectly on my Compaq Presario CQ56 has never given me faults and I am satisfied with the product acquired, remember that you must update your pc to 64 bits to take the 16gb of ram
Summary: I put these in my Dell M6700. Easy to installed and works. Have had it running for around 18 months and no memory issues to date. I left the 8GB I had in the system in and added these so running 24GB RAM now.
Summary: I simply popped open the back of my laptop and removed my older memory and applied the little panel back turned on the computer and i was rolling. Very simple and a great way to speed up your computer. I even bought another to double up on the speed after this one took so easy.

Summary: I ordered this for a Lenovo W540 and it worked perfectly fine. I ordered the same thing for T440 and it didnt worked, I opened & closed the computer 5 times, tried disconnecting internal battery, played with Bios, ran other softwares too and ultimately installed the same 8GB RAM in an old T410 and it worked. When I explored forums then I realized that T440 supports 1.35 low voltage, whereas this one was 1.5 which not mentioned online by the seller.
