How I overclock my 940 Mhz stock clock Sapphire R9 280 Dual-X ?

Is there any ratio of changing GPU Clock speed, GPU Voltage and Memory clock ?

You can try AfterBurner tool to overclock your GPU. For overclocking with Afterburner, first set the power limit to max available then try a 50 Mhz increase on the GPU clocks and check of stability by running Heaven Benchmark for some amount of time to make sure there is no visual corruption or stability issues. If it runs fine then push the GPU clocks by another 10Mhz and again run the benchmark for sometime for stability test. Keep increasing the GPU clocks by 10 mhz each session till you see visual corruption or crashes. When you find the maximum stable GPU clocks you can do the same procedure above to overclock card's memory too. Also monitor GPU temp and make sure it is not exceeding 85C while on load.
