Two R290's Help me set up mining
« on: January 05, 2014, 10:11:00 PM »
I'm trying to mine with 2 R290's.  I have mined before with bitcoins and GUiminer.  I'm having trouble mining with the CGminer... I'm mining through Wemineltc as a pool.  What would my settings look like for CGminer to optimize the 2 R290s?  Also, they are currently set in 'crossfire'.  Should I disable Crossfire in order to get the most out of them?  And finally, when I get cgminer going it doesn't show any kind of menu read out for hash or anything.. It's just a blank CMD prompt. 


Thank you for anyone who will take the time to help me.  I'm feeling rather stupid here at the moment.

Hi there,


i have the same problem with my 290x. I dont get CGminer to run. After days of trying i gave up.
My 290x is watercooled and i read about a bug when you dont have any Fans at the Graficcard. (Watercooled)
I cant confirm this.


Now i am using GUI Miner and it works well.


My advise woud be to


1. deactivate crossfire
2. lower GPU voltage
3. maybe run 80% Powertarget.


With this (2. +3.) i lost around 5 to 8 % Khash/s but lowered my energy from 350Watt to 305 Watt
At 70 % Powertarget i run 800Khas/s at only 275 Watt. Might be worth a try.
