I tried everything to overclock this thing and copulnt get over 50 mhz out of it till i stumbled on the r520 overclocker or "R5WinClk" and even then it wouldnt clock up very well, i then set voltage to 1.5 ramped fanspeed to 100% manualy and went to bed. Today after some burn in this thing does 900 core and 920 memory im freaking amazed. i havent run benchmarks and i dont beleive in them but crysis shure is running a whole hell of alot better. Its like a whole new game without all the lag i had before. here is my validation... http://www.techpowerup.com/gpuz/7zyve/ Its totaly game stable, this is hard to believe for me, and i did it. gpuz and R5WinClk cant be wrong can they? Im thinking gpuz has to be right? am i wrong? Somone tell me WTF !! is this for real?
