| Post subject: | Crossfire/SLI Question |
I was just wondering if in order to run 2 cards in Crossfire/SLI mode, do they have to be the same card? I know ATI - Crossfire and Nvidia - SLI but would I have to use the same ATI cards? Can I use two different ATI cards? What are the limitations on those cards? |

For Ati the have to be the same core. They can be different manufacturers, memory sizes or clocked differently (each card runs at it own speed) For example: HD3870 + HD3850 HD4870 + HD4850 http://game.amd.com/us-en/content/image ... July08.jpg For Nvidia they can be different manufacturers, different clocks(card clocked to lower speed) and different memory size. I suspect that the number of shaders must be matched as well, which screws up things on a pretty collosal scale on the Nivida side as they have cards with the same names that are different, and cards with different names that are the same (9800GT = 8800GT) |
