Windows 7: Trying to setup 8 screens in Windows

Hi All,

I've got a RAMPAGE III EXTREME and 4 x ATI HD 4650 cards in PCI-E

4 cards show in device manager
4 cards have been tested in another pc and work fine

I connect 8 screens and only 6 will show in the display properties so I could use the first 3 cards and it displays or the first card, skip the 2nd and use 3 and 4 i get all 6 but as soon as I plug in monitor 7 and 8 it kicks out the 2nd gpu.

I've replaced the motherboard which did not help.
I've flashed the BIOS to the latest version which has not helped.

Can you help?

Thanks

Hi Steve, i hope that you have followed these steps:

just check this as the steps are same for multiple screens as well... as i tried with 4 monitors & it worked but want to be sure that you've done the same.
