Can someone with a 4870x2 please check the max AA (box) in CCC?

Until today there were 4 options for AA (box) in CCC: 2x, 4x, 8x and 16x. Then Catalyst 9.6 suddenly stopped working, so i had to reinstall the driver. After the install the slider in the AA tab changed, i could only choose 2x, 4x or 8x AA (box).

After googling a bit, i read something about 16x AA (box) only being able to be enabled on CrossFire setups ( see http://www.rage3d.com/print.php?arti...0/crossfiredx9 look for CROSSFIRE EXTREME QUALITY).

The obvious conclusion is if that really is true, then CrossFire must not be working on my 4870x2 and thus i can't enable 16x AA (box) on CCC.

Can anyone with a 4870x2 please check what is the max AA (box) you can set on CCC?

I've formatted Windows and tried multiple drivers and nothing has changed. What could be happening? The card was running fine just yesterday.

This is how my overdrive section looks like

Here is what Device Manager shows

I tried a bunch of different drivers and clean installs but nothing seems to work. RMA is the solution i guess?

No, the cards are fine. What we are seeing is a very very common Windows problem, that I sometimes get with SLI when updating the drivers. For some reason, Windows fails to install the driver for the second card and finds it not working.

Just right-click on the card with the yellow warning icon, select "Update Driver", then "Let me choose the driver to install", and select the ATI driver from the list, it should already be there if the first card is working.

Hope this helps.

Yes, and that's not much different than two GPUs on two separate cards. Windows is having a hard time finding the driver for the second GPU, and needs someone holding its hand.

If you look at the Device Manager screenshots, you'll see what I mean.

Every time the driver is changed, there's a chance Windows needs to be manually told which driver to use for the second GPU. That includes driver updates, hardware changes, Windows reinstalls, even a video driver recovery in Vista can do this.

I know, in a perfect world, it should all be pink and shiny. I know what causes it, but have close to no clue as to how or why. Anyway, once both GPUs use the same driver version, it should be fine until the next update. I bet he'd be seeing a lot more hell if something on the card were defective.
