When I mine using GuiMiner, I am only able to mine with 3 cards at full capacity, or 4 cards at low capacity. Anytime I try to turn on the 4th card at full capacity the system shuts off and restarts.
I have re-installed windows and the mining program itself, but the issues persists. I will try to run CGMiner to see if its GUIMiner thats causing the issue.
I also have a new Lepa PSU that is 1600W, 1700 peak. That should be able to handle the system I have listed in my signature. But I am also inclined to believe its a bad PSU that isnt supplying enough power to the 4th card so it crashes the system instead.
Thoughts?
