Yeah, I can help. I just did this with my 4 7970s this week. That whole ratio thing didnt work for me. I got my core as stable as I could and then the memory you want between 1700-1775. Concurrent threads I used 8192, GPU threads I used 2. Also I would make a new miner tab and no use the drop down for the presets. Hopefully this works for you as it did for me. I was able to get one card to about 700khash but with all 4 going its about 600-650ish. Let me know if this helps you.
