After the relive update and the introduction of wattman on all the GCN lineup I am havin big issues on my Sapphire R9 290 4GB with reference cooler.
First of all the memory frequency does not increase automatically when I connect two or more monitors so flickering on all the screens occurs, it is so annoying that I had to disconnect two of my monitors.
Second issue is that the fan won't spin as fast as necessary in auto mode to keep the core frequency stable. This happens no matter what target temperature I choose, so if I set my core speed at 950 for example the core will run around 750mhz and 900mhz unless i set a fixed fan speed or utilize external software. This is also very very annoing.
I've heard of voltage messups and overclock performance issues, but i'm fine with that.
Just fix this two Issues guys because for now I'm forced to use old drivers.
Try 17.1.2 driver. It has some optimizations for multi monitor systems
1.Delete C:\AMD folder
2.Uninstall all AMD software and clean your system in safe mode by DDU program and install 17.1.2
