which model do you have? the 3 slot version or the 2 slot? (the 3 slot is v2, the non v2 version is the 2 slot one)
I have the 3 slot one and can get nowhere near that, lucky with 280/300
Is there some reason you guys with the R9 280 have been setting the power tune to negative 20? The way I have seen a few of the examples on here they say --gpu-powertune -20 that actually sets it negative unless you get rid of the "-" in front of the 20....might be why some of you have poor speeds
