    Dear Samail,

    Because we don't have Sapphire HD7950, I did the test with HD7970.
    Below is my test config.
    CPU: i7-4820K
    Memory: DDR3-2133 8GB
    VGA: HD7970
    OS: Windows 7 64bit
    BIOS: P3.20

    The VGA card can work at Gen3 normally.

    Please follow below suggestions to try.
    1. Load BIOS default settings and only set PCI-E speed at Gen3 to try.
    2. If possible, please test another Gen3 VGA card on system to verify.
    3. If possible, please test your VGA card to another system to check if the card can work at Gen3 normally.

    Thanks!

    Have a nice day

    Thank you for the information. I did step 1) from your suggestions many times through my tests. On Saturday will test my VGA on another PCIE 3.0 ready Mobo and another PCIE 3.0 ready VGA on my Mobo. Will post the updated info then. If you have any other suggestions or advices - please be welcome to share!

    Updated info!

    Hello


    I found the source of the problem after i set my VGA on another PCIE 3.0 ready Mobo with PCIE 3.0 ready CPU. The card didn't start at 3.0 again. The VGA BIOS is 015.025.000.099.000000. A friend has exact same VGA as mine, but his BIOS is 015.034.000.005.000000. I extract his BIOS through GPUZ and load it on my VGA through ATI Winflash. Now my card works with PCIE 3.0 but now nor my drivers, neither GPUZ shows my current clocks, pixel fillrate, texture fillrate and bandwidth. So I create Sapphire Support Ticket and request proper BIOS for my VGA Card model. Hope they will respond soon and send it as soon as possible.
