    DZ77GA70K: graphic card only running at x8 speed

    DV_Chris

      I have a DZ77GA-70K here (latest Bios 0061)  with an Intel 3770K (not overclocked), 16GB (2x8) memory and a Nvidia GeForce GTX 650 Ti running Windows 7 Pro 64Bit SP1 with all updates applied, all drivers are up to date. Apart from the graphic card in the first x16 slot (Bios: Slot 6) I have a x1 card in the second x16 slot (Bios: Slot 3). It seems that putting a card in the second x16 slot immediately reduces the speed of the first one?! So my questions are:

       

      1. Is this behavoiur know and/or normal? Couldn't find anything in the manual.

       

      2. If it's not normal is there something I can do apart from removing the second card?

       

      Thanks in advance for all your answers!
