Yep. Claymore supports 10 GPUs max. Try running claymore for the 470s and ewbf (equihash) for the 1050s - you'll make more that way anyhow

Thanks ozoner.  Thankfully was able to figure it out via a youtube video.  It's the -di switch that allows choice of cards per miner. So I split between two instances.

Had some port issues after that but now working.  Will have to check out zcash soon, ethereum is cranking right now though, I guess all the coins are! Hard to find to time to pioneer new coin right now but definitely going to give it a shot when I can.
