@claymore : Is it possible to use your miner on miningrigrentals?  if so could you help with the options.  I've tried multiple qtminer combinations, but so far nothing works.  according to miningrigrentals, they have a qtminer example that shows :  qtminer -s us-west01.miningrigrentals.com:3333 -u username.rignumber -G

Love all the work you've done on this miner.  Thanks!!!
