Summary: It works good. Installing it was easy, and had no problems whatsoever. Using the Corsair Dominator series in my desktop and have always been a fan of Corsair ram! Pretty reputable, and the price isn't bad either.
Summary: I bought this ram on accident thinking it would work with my new ultrabook. I gave it 5 stars because returning it was fast These are ment for 2nd and 3rd generation processors: Sandy and Ivy bridge. This ram runs with DDR3 1.5v, so if you have the 4th generation Haswell processor, you need to use the DDR3L 1.35V RAM. I hope that prevents someone from making the same mistake I did.
Summary: With AV, firewall, spyware and with other software installed, my windows 7 laptop with 4gb RAM booted to a fully-usable state in a rather slow 1 min 20 s to 1 min 30 seconds. Put this 8gb stick in and that time reduced to around 50 seconds to 1 min. Yes, I did timed it before I put the new RAM in to confirm if the new RAM really matters when it come to speed. That's a really good result for such a simple upgrade.
