Hi all.The gpu i have is the VTX3D Radeon HD 7770 x-edition/Ghz edition.I heard the best way to overclock an amd gpu is by using the overdrive feature of ati catalyst client.Is this a good and safe way to oc this gpu or there is anything better?And how i can OC safely.I need a step to step guide to avoid gpu crashes.Thank you all,EternumSpace

You probably should google 7770 overclock guide to get an idea of how much you can overclock that card. Also, DO NOT increase the voltage on the gpu unless you are sure of what you are doing as this is a quick way to fry your card from overvolting. http://www.youtube.com/watch?v=gA_l5-HDel4 http://www.guru3d.com/articles_pages/amd_radeon_hd_7750_and_7770_review,23.html

http://www.kitguru.net/components/graphic-cards/zardon/vtx3d-hd7770-1ghz-edition-crossfire-review/20/ In this site they are tested the same gpu and they found that the max oc that is able is 1125 core clock and 1225 memory clock.Is this good?Shall i follow this guide?Will is this a good oc percentage for playing games (11%)?

11% is an ok overclock. Personally I have overclocked by around 20% but it depends on your system and what kind of temperatures you are getting

I would slowly up the overclock until you find a setting you are happy with, i.e. no weird coloured blocks (artifacts) and the temps are max 80C when gaming
