You should try swapping the cards so their in different slots and see if the problem comes back. If it does then the card in the top slot is going bad and you should try to RMA it. If both cards work good by themselves then you should look into improving your case ventilation and if that doesn't help then you should look into some better coolers or lowering the cards clock speeds.
True. It doesn't matter though, my new system is crossfire... so I'll be back to one video card anyway.
But I will test it, if it happens on the new system I will RMA it.
If I install the second card into the second Pci express lot, would it act as a Physics card or no? I WAS overclocked 50mhz on everything for EVGA precision..
