Installing 2nd 5870: how do i link the cable

[BTRY B 529th FA BN]

I'm about to install a second card for Cross-Fire. How do I configure the X-fire bridge?

 

[ViRGE]

You just put a single bridge over the pair of cards to link them, and then turn on CrossfireX in the drivers. There's not a whole lot to it.

I don't install them this close do I?

 

[Dorkenstein]

Eek, that's a sammich right there.

 

[BTRY B 529th FA BN]

Yeah, i'm about to use the other slot :\

 

[ViRGE]

You can, although by all means if you can get farther away you should.

 

[BTRY B 529th FA BN]

Well :\ I did



But the bridge connectors that came with the board are SLI sized. I kinda was figuring that before I opened the package.

They will be fine, but if I was you I would get a longer Crossfire bridge so they will run cooler and quieter.

I'm going to leave them far apart like that. I'll just need to get a long Cross-Fire bridge. Which makes me wonder; Do I need 2 or 1 bridge?

SLI sized? As in they're SLI bridges and not CF bridges? Or are you saying they're too short (they come in 3 sizes).

1 bridge.

They are nVidia compatible. The Classified e760 is SLI certified :\ (yes, they are SLI bridges)

So I need to go to MicroCenter or order one from New Egg

 

[Kenmitch]

So your cards didn't come with the CF bridge? Yes you would need to go get one then.

No, they came with bridges but they aren't long enough. I am using the second configuration with the cards furthest apart. I need to find a good vendor that sells ATI bridges (long bridges)

 

[BTRY B 529th FA BN]

I think I'm in trouble, I don't see anyplace selling different sized Crossfire brides.

 

[SergeC]

I've seen them on ebay for pretty cheap.

Yeah, I'm seeing them too (used 100mm)

Looks like I might have to resort to flea-bay for a dream machine to work, hah :\

Yep. Since bridges come with all CF-capable retail cards, there's not a huge market. I'm surprised that someone packed the short bridge with a 5870 though; that's obviously short-sighted.

 

[OVerLoRDI]

I looked them up on ebay, they are surprisingly expensive for the long ones. Usually floating around $25

Well I guess that sucks nutz

So the stock bridge will only reach from slot 1-3 which makes the cards very close together which for decent temps one would have to watercool the cards?

I did look around also and the only place I could find them was flee-bay also

I did find this " Lotes p/n-AAA-ATI-002-KO3 " for the longer version which in pictures is the Asus one anyways.

Call up your motherboard vendor and tell them to send you a long bridge.

My MSI P55 board came with 2 SLI connectors and 2 CF connectors (one long, one short)...which doesn't even make any sense because the the third PCI-E slot is x4 speed and so I'd never use it for SLI or CF anyway.

Failing to include them is bullshit.

 

[BTRY B 529th FA BN]

@ Kenmitch - yeah, I think the cards are meant to be configured in an h20 setup according to the setup on this board. I won't be doing that anytime soon, that's for sure. Although I do have the parts, I can just see myself needing the x58 loop I have setup already for an overclocking build.

I also found a bunch of "crapsus" bridges which I'm assuming were from the P7T X58 or WS boards. Luckily I did find one that doesn't have the Asus name on it. I bought it and there is only 1 left on the sellers page....

@ Matrices - I think EVGA has got this loophole covered as the board makes no statement that I am aware of about Crossfire support, just SLI, so I think they would deny me if I asked; which I agree to doing but I think it's a far shot. Anyways, the "100mm" Crossfire bridge has been purchased..
