yup...you're topping off right where I was at when I was on the pi. I'm loving my Odroid N2 setup being able to turn it up all the way if I want. I've settled at 700MHz for my R606 and have my early Father's Day gift (Newpac) running at 500MHz.

The N2 is a bit overkill cost-wise for a basic miner controller, but I'm also going to try running some staking wallets on it as well as my cgminer for the Gekko stuff and bfgminer for the Futurebit stuff.
