First post - forced to share it here.

For those that have asked the question about the Z87-G45 board in other topics, I hope a forum search leads you here.

I've had one hell of a time like you to get this going, so if it works for you, and you're happy, feel free to tip 13KPB3KqfHUSYVhBBSs47sLZdM9NTcJgBp

What you need to do is:

1) In BIOS, set PEG 1-3 to Gen2 - It's under Advanced then PCI

2) Install into all slots except for slot 4.

3) Use a wire to short the pins on Slot7 like this.

4) Use this... DDU Removal whilst in safe mode, to uninstall all the drivers you've installed so far.  http://www.guru3d.com/files_details/display_driver_uninstaller_download.html

5) Reinstall on reboot, this new working driver. https://www.dropbox.com/s/vnemo9n1vmyr812/AMD%20Catalyst%2013.1%20WHQL.rar
