to be honest i am disappointed the given specs 450sol for Nanos are no way near (between 395-410) i think voor Nano the speed is about the same as 11.1, Optiminer is quicker (atleast for Nanos)
Claymore made The same speed as optiminer.. I think he still can get more speed.
Temps/power is lower but speed is about the same as optimizer. So for those that pay for power, it is a nice improvement. in my case that is
