Help: Can New Cards be Crossfired using old bridges?

post #1 of 4
Thread Starter 
Alright guys,

So I just got loads of new gear to update my system and one of my purchases was a HD 7870. I have one already and am going to Crossfire them in the new rig. However, I forgot that the card came with no bridges and the new mobo (MSI 990-FXA GD80 V2) only has damn SLI bridges. I stupidly assumed that since my old MSI mobo (790FX-GD70) came with Crossfire bridges than this one would too. So my question is can I use the bridges that came with the old 790 mobo for my two HD 7870s or have they been updated and made better/faster since then? Are they even compatible? If I could use them would there be a speed difference from any 'newer' bridges? If the answer is no, would any stores like Best Buy or Staples or something have bridges that I could go out and buy versus having to order them? I really want to get started on this build biggrin.gif . Thanks in advance.

I have xfired 6970's with old bridges and it has worked just fine. The pin configuration has stayed the same. biggrin.gif
