    ASUS P9X79 crossfire problems[SOLVED]


      My setup

      ASUS P9X79 Intel X79 Soket 2011 DDR3 2400MHz (O.C.) SATA 3.0 Usb 3.0

      SAPPHIRE R9 290 TRI-X, 4 GB, PCIExp, DDR5, 512 bit, 1000/5200

      EVGA SuperNOVA 1300 G2 1300W 80+ GOLD

      Windows 7 64 bit with sp1


      So i added one more of the same graphics card. Thought it would be easy like plug n' play but couldn't make it work.


      What i've done till now.

      -The card is installed and the power is connected, the fans are turning i checked.

      -Tried both the cards on the top slot, they work fine alone

      -Updated BIOS to the latest version

      -Uninstalled and installed graphics card driver with display driver uninstaller

      -On the windows device manager or gpu-z second graphics card is not shown


      I don't know what i'm missing. I'm pretty sure there must be a setting on the BIOS but the menus are really simple and i couldn't see an option. Tried to change the PCI link speed to GEN1, GEN2, GEN3, nothing happened.


      Any ideas?

          If someone as stupid as me experiences the same problem, it was the cable connected to the PSU. As i inserted it properly everything went smooth, it was as easy as plug n play. I don't know how the fan was turning without power before but i really don't care as i'm relaxed solving the problem after a long day.
