Hi, I got a HD 7770 dcu2 2gb today and it is running great. I overclocked a lot earlier with 1020mhz core to 1150 and 4600 memory to 4760 without changing voltage and got bsod. After restarting, my PC is running fine, but just wanna make sure my GPU is not defective and that was because my ovetclocking, not because the GPU. I will run stress tests at stock speeds tommrow o make sure nothing is wrong. Help! (Cx4300, ga78lmt-usb3, fx 4300)
