Crossfire cards?

post #1 of 12
Thread Starter 
How does this crossfire work exactly...will any ATI card work as long as you have the ATI crossfire chipset? That adapter would hook up to any card I'd think. I see some cards that come out and say "Croosfire" and I see others where the only mention of it having crossfire capabilities are the user reviews on newegg...which I know not to completely trust.

I am highly doubting that any ATI can do this...but I figured I'd ask before I jump my nVidia fence.

Also...

Do you need two of the same crossfire card? For instance could I add a cheaper 1600XT to help out a X850? It sounds like there may be some tolerance in there for such things.

The adapter is external unlike the Nvidia SLi setup.. And yes, you need to have a crossfire chipset, but there very expensive and dont OC that well. Yes, you need to of the same exact cards to run crossfire (ex. 2x x850's insead of 1 1600xt and a x850) it's the same with SLi.

Crossfire is not fully baked yet. At least SLI has gone through some paces.

Some useful reading

ahh shoot well that's what I expected...SLI is more simple in determining if can the card can SLI or not...it has to have the connections for it. The crossfire cable should plug into any thing.

missed one thing though...

I know you need the ATI 200 chipset for Corssfire...but could I crossfire two 9800's with it? That is my main question, because I see other people saying they are crossfiring cards that do not have the word "Crossfire" in their name.

I think two 1600XTs would do a nice job and would be relatively cheap...if it works that is

Uh, 9800's are AGP so no... you need 2x PCIe cards

*slaps self* Duh I over looked that...but I was using a card for an example. I have had a little experience with a 9800...

Any way...would any two PCI-E ATI cards work for crossfire?

Planning on making my fire ATI/Intel power rig and I'm collecting any and all info I can get. Every thing has been AMD and nVidia for me so far and I figured I should try the other side of the fence.

You need a Crossfie "Master Card" to use Crossfire. They have the "Crossfire Edition" tag insted of XT or XL (so it would be X1800 Crossfire Edition or X1800 CF). You can then combine the Crossfire Edition card with any other card from the series (I.E., a X1800 CF with a X1800 XT). You also need the Crossfire chipset, as people have said. You CANNOT use Crossfire with out a Master Card.

EDIT: The Intel 975x chipset is supposed to support Crossfire as well, so if you wait untill that comes out (it should only be another couple of weeks), get that.

You need three things to run Crossfire, a Crossfire certified motherboard with the Radeon Xpress 200 chipset, the Crossfire Master Card, which will specifically identify itself as such (currently, can only be gotten for Radeon X800 generation, Radeon X850 generation, and Radeon X1800 generation), and a Crossfire ready card, which has to be of the same generation as your Crossfire Master Card.

Actually,you can get two different cards,but need the crossfire edition card X850 or the X800.Crossfire Edition X850 cards can only work with the X850 series and the Crossfire Edition X800 cards only work with the X800 series.Plus,you can hook on two X1300s or X1600s and without using the external cable.

So what do you guys think is better? SLI or CrossFire?
