I've tried every value until 710 MHz no matter I increased the memory clock to the highest value (using ASUS GPU Tweak) and when I reached over that value and tested it with Metro 2033, the screen went black and I had to restart the computer. Could anyone show me which is the highest stable overclocking limit for this card and how to achieve it? Thanks all
