I installed my 2nd 7870 the other day and now most of my games have weird texture glitches. Skyrim for example has random lines on the screen that are in game not just on screen that blatantly do not belong. I have Catalyst 14.6 Beta Drivers installed. All hardware is installed correctly.
Please Hep

More about : crossfire

Tell us more about your system please!!!!

Have you tried the new 7870 on its own, to confirm that it is working 100%?

Are the cards seated correctly on the motherboard? Is crossfire enabled in CCC? Have you attached the crossfire connector to both cards? In your bios, are both PCI lanes set to the on and set at the correct speeds? If so,

1/remove your new card and try again, if your old card is good,
2/remove it and install your new one in its place,
3/try this card
if that's ok, go back to step 1 in lane 2 and repeat.

If all are good, totally uninstall your graphics drivers using ati's uninstall utility, then reinstall your graphics drivers again preferably not beta!

Good luck

All cards are seated correctly and respond in GPU-Z. I installed the latest drivers from Catalyst that are out of beta. Problem persists

Bottom-of-the-barrel. Not something I would put in a PC I build for myself. Or build for a friend. Or an enemy. Or Bashar al-Assad.
