Summary: I purchased this memory kit for a new PC build but was did not get to it right away as I was in the hospital. After installing the memory I noticed it was just 2 4GB not 2 8GB as the package said. Beware. It is too late for me to return it to walmart. It was sold by TigerDirect. Don't who I should contact. Thinking I'm out of luck since so much time has passed.
Summary: Going up from 4gb to 16gb and being able to run my i7 3770 on XMP has made a world of difference. the only problem I ran into was I had to orientate my freezer pro rev.2 away from these sticks cause of the tall heatsinks but that's down to my dinky motherboard lol Overall chuffed at purchase and would buy them again
