SLI 6970 Help Please

[CulabunT]

I currently have the --->Asus Radeon 6970 DirectCU II 2GB it's factory OC at 890Mhz

If i got another 6970 differant Brand and not OC, but at stock 880Mhz would that still work fine in SLI???

Or do i need them to have the same Mhz??

AMD Radeon cards connected are called Crossfire. SLI is Nvidia.

It will work fine. I've heard the slave card will adjust to match the master card. Or you can always just change it yourself to make them match.

I just get confused about whats called what these days, means the same thing. well ty, cause i want to Crossfire 2 6970, but the current card i have is expensive... well thanks

 

[CulabunT]

also can the card that has the smaller Mhz, be put in the PCI-E slot1?? or does the faster card have to be there?

 

[shane799]

you can go either way. The faster card will lower itself to match the faster card regardless of which is in which slot. I would think more about which has superior cooling and put that in the slot which will be getting choked off.

well i would but, have you seen my current card, it cover's my other x16 PCI-E slot... so i need a different card in the first PCI-E slot

They will run at what ever clock you have them set at. If you leave them at stock, one will run at 880 and the other at 890.

Each frame rendered by the cards will have ever so slightly different speeds of being rendered. Each card renders every other frame, so they really don't have to be the same exact clock to function. However, a large disparity may result in something similar to a microstutter, but it probably needs to be a huge difference to see something like that.

oh ok, thanks you
