... AX1200i
You have a very decent PSU. Keep in mind, that if the PSU pulls 1000w from the wall this means your rig is pulling arround (1000 * 94% efficiency = ) 940w. Your PSU should be able to deliver 1200w output, so arround 1275w from the wall. I think you are good to go from that perspective. I guess your PSU is faulty or the connections to the GPUs are bad and the voltage drop there is to big. Do you have any PCIe 8 Pin splitters on it? Maybe their Ohm resistance is too big.
No i dont have any splitters, for 6 cards i use 6 pci-e Cables, 4 of them have 1x8 pin and 2 of them have 2x 8 pin.(i leave the other 1x8pin), my cards only takes 1x8pin anyway.
I have read alot about my gtx 1070 with micron memory that it will crash sometimes when it goes from idle voltage to full load voltage.
Solution was to set "prefer maximum performance" or to lock the voltage above 0.811v for each card.
Been running now for 2 hours but really dont have any idea if this is the solution.
Anyone else know about this?
Connected my 6 risers with molex directly from psu, 2 risers per molex Cable.
