Hi guys, so i've got an Asus 280x in my rig atm. Now, when i originally got it i used Asus GPU Tweak to fiddle with its settings and run a mild overclock, but at some point that started causing problems so i uninstalled it and have simply been using the Catalyst control center (AMD Overdrive) to get by. Anyway, a week ago i bought a second Asus 280x on Ebay so i could Crossfire them and i figured i'd set up a more aggressive fan profile before it arrived, to make up for the extra heat. So i downloaded MSI Afterburner and went about doing that, but in the process i noticed that the monitoring software always registered a clock speed of 970MHz (the base clock for this card), no matter what clock speed i set it to myself. I uninstalled and did a clean reinstall my graphics drivers but it didn't make a difference, so i uninstalled Afterburner and downloaded the newest version of GPU Tweak, whereupon i had exactly the same problem.
These are some screenshots i took while running Firestrike. It doesn't make a difference whether i try to set the clock speed higher or lower than the default speed, it simply won't change. So my question is, does anyone have a clue why i cant change the clock speeds???
