Got my 2 tubes running on 1 controller, no problems, no hiccups, no issues at all.
Getting a steady and stable 1.6T since last night on poolside on Slush. Sorry, my kill-o-watt died so I can't verify draw at the wall.
I'm using bfgminer 4.7 as a proxy, but I hear Slush got it working w/o a proxy so I'll have to try that.
Otherwise, I LOVE this product. The engineering on the kit is far superior to the usual BTC world crap. The tube concept with one fan and interlocking heatsinks is great and very efficient for cooling. And I really like being able to run 8 tubes from one controller. The other good choice was using a thermal pad instead of paste, mainly due to the apparent lack of workers skilled in thermal paste application techniques.
So kudos to friedcat, and kudos to canary for running this GB and superbly handling the daunting task of packaging all these units, and so quickly!
Now if only AM could improve efficiency a hair, they could give Bitmain some tough competition.
