Rampage III E SLI PCI E Bandwidth

Hellow community!

I am currently running:
2 480s SLI
PCI wireless card
SB X-fi PCI E card

So i thought i'd be running 16 - 16 - 8 (or 4)

But GPU Z shows that my 480s are in:
8 - 8

and the 9800 used only for physx... is in 16

This seems weired and i havent been able to find an explanation.

Obviously i want the 2 480s performing their best and the 9800 is the lesser of priorities here...

Can anyone offer some advice?

  1. Hello
    In which PCI-E slots are you testing your cards? make sure your cards are located on the first and second PCI-E slots
  2. The 480s occupy the first 2 - the 9800 is in the third
    Then wireless
    Then sound card in the last slot
  3. Then its OK, when the third slot is occupied,the other 2 will run at 8x
  4. So i either have to run them like this or remove the 3rd and the first two will be in 16

    i guess ill have to run some tests to see how much different physx games run on high without the dedicated card and just on the 480s...

    Don't worry about it, the performance difference between dual 8x and 16x isn't much.
