Identical GFX cards in SLI??


I currently have an XFX Geforce 7900 GTX (YDER). Factory clock speeds are 675mhz CPU & 850mhz (1.7ghz) memory.

My question is if i want to upgrade to SLI do i have to get the EXACT same card as above or can i get a card with different clock speeds? Would the faster card just lower its clock rates to match that of the slower card?

I guess my question is... How identical do GFX cards have to be in order to be able run them in SLI mode?

Many Thanks!!

  1. No. If you'd even scroll down a little you'd seen this covered.

    No worries though, :wink:
    you need same GPU. So any 7900GTX will work with any 7900GTX. Brands and clock speeds don't matter anymore.
  2. I apologise i did look but obviously not hard enough !

    Thanks for your help anyways!
  3. If you are willing to mod the bios, it could even be a 7950GT or a 7900GT that you paired it with.

    Of course then you'd loose even more clock speeds on the faster card.
