I'm having problems with the Gigabyte ATI Radeon HD7770 OC Edition graphics card. The graphics card will occasionally crash to a grey or white screen and I will not be able to do anything. No error messages are given to me at any time during a reboot of the system. I have enabled "Triple Buffer" in ATI Catalyst Control Center. I have also enabled AMD Overdrive and overclocked the device.
Default GPU Clock: 1100 MHz
Overclock GPU Clock: 1110 MHz
Default Memory Clock: 1250 MHz
Overlock Memory Clock: 1275 MHz
Nothing else has been changed. I have no idea what could cause it to crash and what's even more frustrating is that it also crashed during PC idle time (i.e. When I leave it to download something). Could any one provide me with some help and I have also contacted the seller for a possible replacement.
