Hi,

I already have the two single slot 3870 cards. However, looking at this motherboard (Gigabyte x38), it would seem that the ati crossfire bridge won't be long enough to span the gab and connect the cards, Does anyone know if it would be long enough?

The board setup is (left to right):

PCIe 1x
PCIe 2.0 16x (3870 #1)
PCIe 1x
PCIe 1x
PCIe 2.0 16x (3870 #2)
PCI
PCI

It should. I mean I really doubt that Gigabyte would design a mobo that's Crossfire compatible, but you can't used it because the bridges don't fit.

Yes, that would be dumb. I have the two crossfire bridges right here, but they really only look long enough for something like this:

PCIe 1x
PCIe 1x
PCIe 2.0 16x (3870 #1)
PCIe 1x
PCIe 2.0 16x (3870 #2)
PCI
PCI

I can't be sure though because I don't have the motherboard.

Well, what you can do is put the bridges up to the expansion slots on any mobo and see how many they span. If they only span 3, then they're too short. If they span 4 or more, then they're long enough.
 
Yeah, that would be the way to do it. Used one of my old cases and it spans four, so it should work.
 
Um, doesn't the bridge come with the motherboard? Made by the motherboard manufacturer to span however many slots the board is configurated with?

Thats the way NVIDIA mobos are.

Usually. All my Asus intel boards have come with CF bridges.
 
My Foxconn mobo didn't come with a bridge. But both fo ym cards did. the foxconn has space in between the 2 pci-e 2.0 slots. And the bridge spans 4 expansion slots. Woks just fine.
 
Bridges should come with the cards. The two that came with my 2900s are long enough to span a 2 slot space between the two PCIe slots. So if you have dual slot coolers, they're long enough to have a slot open between the end of the first cooler and start of the second card.
