thanks for the feedback, I do not overclock since they keep going down.  Maybe I have to underclock! And with watercooling they are 45C so it makes no sense.  only 1 out of 4 of the cards on each of my 4 rigs was up today.  But if I don't mess with them, in a day or so they will go back up, and others will fall I don't get it.
