To start, I'm new to mining.  Put the rig below together in Dec '17 and after reading a thousand forums here and reloading everything 10 times over several weeks I have a stable rig.  

I have been mining XMR with this setup on Minergate for a few weeks fairly stable.  Cards are averaging 600 h/s (3.6 k/h total for 6 cards).  This sounds on par with what I read for stock bios cards mining these algorithms.  I decided to see what the cards would do mining ETH and I'm only getting ~11 - 12 mh/s per card (~70 mh/s for 6 cards).  I see a couple mentions of this issue on forums but haven't run into anyone who has solved it.  Any Ideas!?!?  Thanks!!

Update:  Same rig runs ~25 mh/S on claymore.  Minergate seems to show exactly half the hashrate on their dashboard.  Funny thing is I feel like I accumulate Eth faster on Minergate despite the hashrate shown...
