For example I try to use two ATI 5450 videocard in 990FX motherboard (win 7 64 bit and the latest driver). The distributor say this is not possible, because this chipset not support crossfire or sli.

Anybody use that kind configuration? It is work?

The 990FX chipset dose support crossfire and sli but your ATI 5450's do not.

5450 are low powerd, low porfile, low end cards that do not support crossfire.

Now you can run both cards at the same time if your planning on using more than two or three monitors but you just can't crossfire them.

Thank you for the answare Slayerx!

 

The distributor say it is not limitation of card, it is limitation of the driver. I not belive so, because I use pair of Radeon7000 without any problem. But maybe the Hd5x and its driver is a new wave...

I'm not sure what he ment by "limitation of the driver" I'm running a pair of crossfired 5850's on a Sabertooth 990FX motherboard and before that I was running them on a motherboard with the 790GX chipset.

So its not a limitation of the driver its a limitation of the card and the 5450 just can't be crossfired

Apparently it is possible, but the performance is still wretched compared to what you can get with what I'd consider a low end card.

The origiginal problem was, if I insert two brand new 5450 card onto my brand new 990FX motherboard one of them not initialized by opsys. That is why the dealer say this is not a hardware failure, just driver limitation.

 

But now I buy a third 5450 (ASUS EAH) card, I replaced the looks like bad one and all its work fine. Only limitation what I found, if the driver version below 9.x and I plug HDMI montor, then my win7 crash. But with  9.x driver this problem is solved.
