I want to call BS on anyone who claims to get 24Mhs or more form their R9 290. I worked on config setups for some time and I am convinced that people are just misreporting, or people are posting performance results based on multiple card setups

With that being said. The best I can get out of 1(single) Sapphire Tri-X 290's is 15.5Mhs @100W

If you claim to get much higher than 15.5Mhs, I want to see the screen shot! (Please dont try to prove it with a "start up spike", I want to see 24Mhs on a miner that has been running for hours) Otherwise, I call bull shit!
