I Recently bought a Saphire HD 7970 OC of a site called lambdatek and when it Arrived i felt like testing it out on max payne 3 with it on bios 2 (at that time it had Catalyst 12.8 drivers installed). 1 hour later i was just browsing the internet and the card just randomly displayed black and white lines after a few seconds of blackness on the screen.
I thought it was a driver problem so i used ATIman to do a clean install of Catalyst 12.9 Beta after 12.8's removal. It looked like the card was stable again after a heaven benchmark success on the default OC on bios 2, so after just toying around in minecraft i closed the app and a white screen flashed and then turned to blackness after with the screen displaying (No Video signal) again and requires a long hold of the power button to get it up again.
Tomorrow again just using sony vegas lags like hell and causes my system to lock up for a few secs. I used ATIman again and downloaded catalyst 12.4 and installed it. i got a BSOD half way through so i tried again at worked. Every thing seemed fine again then i done a small OC to 1200 on the core, 1450 on the mem and 1.195 v and tried heaven again and it froze on stage 11 and i needed to reboot to get windows up again.
Then i switched to bios 1 and keeping an oc to 1125 on core, 1450 on mem and 1.19 v tried heaven again and this time froze on stage 10 and it took me about 5 on and off's long holds on the power button before i could receive a signal from the card to boot into windows and type this message. What do you guys think the problem is? it's a bit hard to think it's the drivers given i've tried so many. Games like sleeping dogs, MW3, ACR, LOL, Max Payne 3 play great without artifacts or lag with pretty high framerates on max settings.
I would just like to see what do you guys think the problem is, thanks in advance...
if it's the card i will opt for an RMA.
