GPU Bridge/Link advice for Crosshair V

post #1 of 6
Thread Starter 
I just got another 6970 for my rig and will water cool it eventually. I was wondering if I should bother with a bridge/link for it or if I should just use extenders.

If I use a bridge, which one would I get as far as spacing because the layout of the CHV doesn't put the other 6970 in the next PCIE slot.

There's 3 spaces between them.



There's a picture of the layout for those that are interested. The first 6970 is in the first slot and the 2nd one is in the 2nd slot from the bottom.

Any help is appreciated. Thank you.

If I understand the bridges correctly, their description of 1-slot or 2-slot means how many spaces between each card. A 1-slot bridge, will have another PCI slot between the two GPUs. That would let you put both GPUs in the top two 16x slots of the mobo pictured. If you add a third card eventually, the triple bridges are also 1-slot spacing, which would leave the last PCIx slot open.

That's not how the CHV goes as far as 16x PCIE though. It's exactly how I said it. The 1st card goes into the first one. The 2nd card goes into the 2nd slot from the bottom.

I'll have to do some calling to make sure I guess. Thanks though.

In that case, it's still not much of a big deal. Aquacomputer, EK and Heatkiller have dual links for 3 slot spacing.

You'll need a bridge that has three slots in between since your mb has 16x slots are the first and the third red pcie 2.0 slots.

Hk makes one that is designed for two cards spanning that spacing:

With ek, you'll need to buy a "blank" link (either serial or parallel, depending on which bridge you choose) to block off the middle port. I don't have much experience with Aqua, so I can really say what their bridge will do (someone jump in ).
