So i overclocked my card and ran MSI Kombustor, the thing is after a minute or so, the fps drops alot also does the core clock and i dont know why, i don't believe the reason is the temperature, because it barely goes over 70 degrees.
My card is a Gigabyte R9 280X
Default Clocks: Core: 1100MHz Memory: 1500MHz
Overclocked Clocks: Core: 1140MHz Memory: 1650MHz
Power Limit: +20%
1.300 constant Voltage.
CPU: i7 4770k 4.5GHz overclock.
8GB RAM
Here's a SS of the test, once i started the test:

And here's a SS of the test one minute later you can notice the gpu load and the core clocks droping from 1140 to 1030 even less then the default clocks. Also the drop of 50 fps.
