Peaked out at 643 KH/s!!!!!!You and Dave are the freakin BOMB! Now I have to really fine tune my overclock since this actually uses 100% of my TDP, and temps are about 10 deg higher.
Previous version I was maxing out at 433 kh/s with 112x2. Now with this version, autotuning used K14x4 for GPU1 and K14x14 for GPU2. Set it to -l K14x14 for both and I'm getting 643 kh/s from 2 EVGA 670 FTWs!
