thanks Al, this morning I still only have one running, but I figured out one other thing I had changed. I had started running yoyo m Queen on that machine. if I stop yoyo then I get both Gpu's running again. I guess I will have to run yoyo on something else. don't have a clue why they both will not run with yoyo.
