Stike Posted May 4, 2010 Posted May 4, 2010 Hello, Could someone help me overclock my ATI Radeon HD 4850 (512 MB) video card? I was looking for some guides on the internet but no serious guide. If you have one I will be grateful if you post it here. Now I have installed ATI tray tools and MSI Afterburner. Ati Tool doesnt work on my pc. Witch is better to use? On another forum I found that on HD4800 series you can not increase voltage... Is that true? Share this post Link to post Share on other sites More sharing options...

Go to ATI overdrive and unlock it. You can test settings in CCC to get a good overclock. You can increase voltage. Use GPU Tool: http://www.techpowerup.com/downloads/1383/mirrors.php You can overclock via GPU tool too. Watch your temps. I would not increase voltage unless you are watercooled.

joel.monteiro Posted May 4, 2010 Posted May 4, 2010 use CCC ,its safer than GPU tool and easier to use.u cant overvolt 4800 series at least my old 4870 could not, its default voltage was 1.26. Share this post Link to post Share on other sites More sharing options...

It just doesn't save the voltages. You can overvolt GPU and memory. Share this post Link to post Share on other sites More sharing options...
