But 1,3 is for CrossfireX. Use 1,4 for NVidia:
@nooblady2310 , it is essential to install at least one card in slot 2, 4 or 5 while using triple vga setup in hydralogix mode. As I mentioned before if you want to use crossfire you have to install your cards in slot 1 and three. If you want to ad one additonal nvidia card crossfire mode is disabled and you have to install the higher level card in slot one abd the other two cards in 2, 4 or 5. The chipset automatically detects and switches mode when installing catds on pci-e slot2, 4 and 5.http://www.youtube.com/all_comments?v=ohsKWHvErq4&page=1
Here's what you do:
Do NOT use Slot 3 for an SLI configuration. Use 1 & 2 or 1 & 4. Hydra doesn't work with Slot 3.
Install these drivers: http://www.lucidlogix.com/driverdownloads-driver4.html
After drivers are installed and rebooted, click on the new HydraLogix icon. Make sure Hydra is set to Enabled / On.
If you want to see if a game is working properly, you can also enable an overlay to show you cross-GPU scaling. http://hothardware.com/cs/forums/t/54115.aspx
