bigfoot killer 2100 problems

[dandaman123456]

i didnt have any problems with my 2100 killer network card untill i put another video card in, now when i play bf3 my crossfire doesnt want to work right, ill be getting 80fps and then go down to 2 and then 30 or somthing like that, so i did some research and someone said the 2100 could be taking some of my bandwith. Is this true, if so how do i fix it.

Plus i have the asus crosshair iv formula motherbored, so it doesnt have any regular pcie slots only 2 pci and 4 pcie X16 slots.

Basicly whats happening is that one card is running at a 16x pci-e link and because of your killer card being in one of the other slots it is dropping the other card to 8x link... I believe if you have the killer in the bottom slot it is making your top card 8x... it is better to give the top card a 16x link rather than the bottom but The difference between a 16x+16x and a 16x+8x setup really shouldn't make that much of a difference... but you might want to try moving your killer card up if it is in the bottom slot and see if that helps.

EDIT: Actually I went back and looked at the specs on ASUS's website... The bottom Pci-e slot is dedicated 4x link... If it is in that slot it shouldn't affect your graphics card at all...
