I can barely overclock my GTX 970 FTW

[huss4in]

I can't do more than +75 MHz overclock on GPU CLOCK and +280 on MEM CLOCK with my GTX 970 FTW. What are the possible reasons for me not being able to overclock my graphics card more than that?

Just as with CPU's, you usually need to raise the voltage to overclock a GPU. Some cards overclock better than others. You could try reading this or other GTX970 overclock articles on the web. http://www.guru3d.com/articles-pages/msi-geforce-gtx-970-gaming-review,26.html
