Thanks for the update! I did buy a Pi 3 to use as a controller -guess I'll just let it sit on the shelf. As a n00b, I have found that the controller is the most difficult (important) part of my R606 journey.
I tried a new windows 10 laptop and an old windows 7 laptop and could not get the R606 up to speed. Forget using my iMac -I failed misurably trying to make that happen. Thankfully, I had two other laptops, one with windows 7 and the other with windows 10 -I spent several hours tweaking both for mining. (killing the bloat on the 10 was a must to get it going) Now, I have my 2 R606 both averaging 900+ GH/s at 700 Mhz (ish) on 2 seperate controllers!
Lastly, the freakout the other day about data -yes, true story, I used over 1,000 GB of data in a few days -I still have no clue how that is even possible. I discovered it was the new windows 10 machine I originnaly purchased as a controller -I wiped it clean and now it sits collecting dust.
Thanks for the great R606's and all the info here! Now I'm looking forward to learning what I'm actually doing -still no clue, but it's fun!
