9600GT not running at PCI-e 2.0

Hello,

I got a little problem:

I have an Asus EN9600GT HTDI and according to Asus's website the card is designed for PCI-e 2.0
link: http://asus.com/products.aspx?l1=2&l2=6&l3=651&l4=0&model=2103&modelmenu=1
Now I got a GigaByte GA-MA770-DS3 motherboard which also supports PCI-e 2.0 according to their website
link: http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ProductID=2722

The problem I got is that the card runs at PCI-e x16 instead of PCI-e 2.0 x12.
I've attached a screenie of GPU-z and CPU-z.

How comes that the card isn't taking advantage of PCI-e 2.0? I've looked in the BIOS but I can't set it to 2.0 in there.

Thanks in advance,
-iDont

    Run a differant diagnostic program on it like sisoft sandra or everest, Im not sure how its suposted to report it but your bandwidth looks good, i just looked up a stock card and it says 57 your card says 64.

  2. Hello,
    Thanks for your reply. I've downloaded and installed SiSoftware Sandra.
    Unfortunately, it also reports that my card is using PCI-e 1.0



    Anyone know how to set it to PCI-e 2.0?

  3. I wouldn't worry about it too much. As long as it's running at X16 it won't hurt performance overall.

  4. i used msi 750i and reported as pcie 2.0 , do you use intel chipset?
  5. Again, thanks for your replies.

    I know it won't hurt my performance that much, but if both the motherboard and the graphic card support PCI-e 2.0, then it just should work that way IMO.

    And I got an AMD 770 Northbridge with an AMD SB600 Southbridge, no Intel chipset.
