I clicked it and I am getting 2560x1600, but i am still getting flickering and random green artifacts randomly everywhere...
I had similar green pixel flickering on 2560x1440 and this is common for this card when using DL-DVI connection. I got rid of those artifacts with high quality DL-DVI cable though.

The Asus DCII has 2 different DVI oputputs for 2 different use. Be careful to use the good one. smile.gif And there is a switch on the card to choose between single link vs dual link.

You are probably simply using the wrong connector or didn't put the switch to the correct position:

311

For the green artifacts, you simply have to remove the backplate and put some thermal pads directly on the VRMs. Be sure the pads are thick enough to touch the backplate with the backplate back in place.

I had the same problem with mine. My 7970 DCII was artifacting at stock speed lol! Putting some EK thermal pads on the VRMs on the back side did the trick for me. smile.gif

See that cord workers perfect with any other card high or low end I am using ... So why would i need to spend a lot of $$$ on a high end DL DVI cable?

For kicks and gigles, what cord you using?

The switch is in the right possitin (or I would have not been able to get to the 1600p rez, and i am at stock to!!! OMW when I was testing it out on Fuchure mark i was getting like ... 2-5 FPS more then my Asus 670 DCIIT ... and that card was/is fast! I like this card but the random GREEN artifacting and the (yes weird i know) clicking on of the fans ... I am super sad at this point frown.gif (when it was being pushed hard and spun fast it started to click!! OMW!!!!)

I have been though 3 of these DCII 7970's

All have the Green Pixel issue when using DVI-D on anything over 1080p

I have tried around 4 DVI-D cables of various lengths, and even a £70 one!

I don't want to RMA it AGAIN thus am using a DP-DVI apple adapter.

Just such a pain that on 3 cards its the same issue.
I know its not my monitor as my 6950 worked fine with my monitor
