Decided to flash one of my new ATI HD4770 to the Asus TOP bios so now I can use CCC to 1000Mhz GPU , 1200MHz GDDR5 and Asus Smart doctor's voltage adjustment works fine ^^ and now 1000MHz @ 1.21v and GGDR5 @ 4580MHz is possible just with fan @ 100% with is just crazy for that cheap card



well its not safe to use cz at these speed have started to show random green lines and artifacts on the display while using Vantage.
