after a few hurdles when you install the memory works fine. You should set the voltage is not as specified on 1.5V, but let the motherboard looking setting and automatically set (with me on a Gigabyte EP45-DS3 there were 1.8V). During installation (at me under Vista64 and Win XP) I was able to insert the second memory module until after the software installation, previously gabs always an error message, partly. Even a blue screen.
But as I said, for these cliffs of memory running as it should.
