That complaint on that build is all over the web. I've yet to see anyone nail it everytime. Sometimes you find folk that tweaked memory timing, others replaced every part and didn't fix it which points to a basic rig issue. That is, time to change cpu maker and board.

There are so many folk with this issue with that sort of build that well, hard to ignore all the pleas for help.

And then you have folk that want a fix for what they have. My lesson over the years is to accept the occasional lockup on that build. Or just make another Intel. rig.
