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?
