Hi, i have a problem. i used to have a 7770 HD in my computer, ran fine but when ever i overclocked it over 1100 mhz (even as little as 1105 mhz), when ever i start up a game (im guessing whenever my card goes to its overclock mode) my game crashes and im back at the desktop scratching my head. but for the holidays ive recently picked up a AMD R9 280x. and it can go way higher than my 7770! problem is it wont, same thing happens, i still cant go over 1100 mhz and i would like a little more power in my gaming. please help!

Graphics card:First card: Asus AMD 7770 HD 2 gig. NEW card: Dual X Saffire 280x 3 gig
Processor: AMD FX 6100 6 core
PSU: Senteny 750 Watt
 
Solution
GPUs are all different. The overclockability of any given card is random. You could get a bad card in one batch, and the one made right after could overclock its life out.
