Edit to say, after to put again the firm 0.99.1 tune, i have a little problem with voltages.. it was crazy.. now is working well after reset to factory defaults in advanced but a line 12v of my 1100w PSU now is dead, i got a screenshot, any idea of this?



The VRM are designed for 40W, many of us regularly push them to between 50-60W.
At 70W per VRM I think you are on your own in new territory!

Your screenshot shows 70W per die (per VRM also).
70W x 4 die = 280W per ASIC

Add AT LEAST 10% to that because the VRM's use that much before even cooking them by overclocking.

OVER 300 Watt per ASIC is what your power supply was asked to do before failure.
(you were asking for >1200W from a 1100W supply)

I suggest 300W per ASIC is possibly too much.
Almost definately too much for a single PCIe 6 pin power connector.
You can install another on each module, KnCMiner provided for that on the PCB.

YMMV

Good advice! Greed is NOT good Mr. Gecko!
