So as the title says, I have a Gigabyte R9 280. While gaming the voltage keeps switching back and forth between 1.125 and 1.250 and the core clock switches between 950 and 1072 MHz. One second it will be 1.125V/50 MHz and the next second 1.250V/1072 MHz. It keeps doing this over and over and I have never noticed it doing that before today.

 

Also I noticed when I first start my PC the card will idle at 300MHz, but after gaming if I check it will stay at 500 MHz and I can not get it to go any lower. I tried opening AMD Overdrive, through crimson, and manually lowering it to 300, but it won't go back to 300 unless I restart my PC. I saw this thread ( https://community.amd.com/thread/204525?q=IDLE%20AT%20501 ) which is similar to my situation.

My GPU is hooked up to a TV through HDMI, no other monitors are connected to the GPU, however I do have a second monitor running off of my integrated graphics (iGPU). It is plugged into my motherboard via VGA.
