I've been told that Linux BAMT works better than windows with the R9 290 graphics card.
Maybe that is something to give it a try.
Got this up and running in 5 minutes - all 5 cards working, no issues. .. it is BY FAR easier and better equiped for 290 cards. I had downloaded it two days ago, but was reluctant for having to learn one more Linux system.. .but there was nothing to learn. edit the config, start it... it even finds and installs your cards for you.
ive tried bamt, it kept rebooting my pc(h61 pro btc, celeron g1620, enough ram.) can you send me a link of a working Bamt version that doesnt mess up your usb stick
