I live in Canada so it took about 3 weeks to reach me for some reason but other than that they installed easily and work perfectly.

These work fine. I did have a problem when I added them to my handful of functioning 2gb modules, and got a memory error. I talked with a chat and was told to try them one at a time. That worked, but they sure don't want to play nice with those 2gb sticks…
