Id also like to thank everyone else who tried to help. Have a merry christmas and a happy new year.
Sorry, beside messing with cables in case something is loose, its hard to say if there is anything else to try to fix it. The next thing to see, if i missed it, would be to swap the controller to see if the problem follow the blade or the controller. Just to double check its really the blade thats gone bad.
And i also did not see anyone reply for the EVGA G2 1300w. The answer is definitively. You'll lose 1%~ AC/DC conversion efficiency over optimum load however. I'd run two of them at 393hz on one.
I have another S5 and its working perfectly since day one, running OCed at 400M. Needless to say... proof is quite clear that we are looking at a dead hashing board.
I asked the EVGA question since the first reasoning seemed to be a dead PSU (I have a couple of spare EVGA 1300w). I thought that if my Corsair died I maybe could've run both my S5s on one EVGA 1300w.
Well, yes you could. Most of my S5 do 393 for 1.29TH/s. One of them do 1.32TH/s at 400, but the others don't get the right voltage it seem, so i leave them at 393.
