One more strange question for anyone out there. I've tweaked my OC settings (I have 4 identical Sapphire 470 nitro 4GB) 3 are now running 300-305 H/s and GPU3 is running 205-220 H/s. I am at a loss why this one is so much slower???
Any help is appreciated.
same problem on some of my ring, also happen with eth 6x 470 running at 27.x mh and gpu 3 running at 24

but mostly the same with 5x 470 has not problem
also one 1 of my 380's ring there it s gpu 2 what is slower
