This will be the home office computer, so above all it needs to be stable. I don't need it crashing while my wife is working on it... she'll put it on the curb and I'll never see it again
Run the test again and try to boot with only 2 sticks in. If it crashes, swap the sticks out for the other pair. BTW......turning off the XMP was a good decision. Two of my computers support it.....both crash or won't boot with it on. Something about not syncing with the clock settings of my cpu. (even with no OC) Come to think about it, those are the culprits right down there at the bottom of my stuff. Also IF your wife's computer happens to be running 10, Set up a drive with a different OS and see if it still crashes. Not very often, but occasionally, I've had to re-install the OS when I just added ram. My guess is something counted the ram and doesn't want to run right when you add in more.
