Is crossfire stable ???

[Franco_cov]

I am looking into getting 2 cards for crossfire for my asus rampage board and as i have always had nvida and briefly had a go at sli both cards simply got detected job done. But I have just read the following on another forum:-

"This hardware is all new

problem :

When I insert both cards they both seems to get power and have their fans running
I connected both crossfire bridges

Now my computer only seems to detect one of them, even at device manager it only sees one , and the other its says unknown pci device ( I have no other pci devices )
When I try switching the cards in slot, I get the same problem, so it looks like there is nothing wrong with my cards. I though about maby the motherboard, but would be strange that his fan is going, and the computer detecs an unknown pci device.

If tried allot of things but nothing seems to work.

I asked some peeps and they say there are allot of problems with ati crossfire... hope I can get it fixed.

I don't have the same setup as yours, however I have 2*3870X2 cards and in order for the second card to kick in I have to have a monitor attached to it as well as the first card then I see all four GPUs


And ..................


Nope, its an OS limitation, in XP you can only Crossfire 2 GPU's. You can however use more than 2 GPU's in none Crossfire mode in XP


So is there problems with crossfire??? I have also read that you get "stuttering" between cards if you have 2 cards in xfire? does this mean jerking on screen etc ?

I appologise in advance if these seem like stupid qustions as I am new to 2 card setups and briefly had a play with sli which you simply just plugged them in and your done??

Any truth in this ??? ^^ BUMP ^^

The only trouble I had when I was running dual 3870s was that they wouldn't work properly when I resumed from hibernation.

It's actually probably easier to set up than SLi, and it scales better in games too.

Is windows stable? lol...
Crossfire is good as long as your games support it. Some games don't, and some just throw their dummies out the pram, along with me. An x2 is better imo and I wish I went that route but never mind that's another winge.. lol

Will the above link will give you an idea of what games support it, also cpu becomes a bottleneck, I was only getting 15k in 06 till I upgraded to 3.ghz Wolfedale clocked at 3.8ghz, now I get 17 1/2k.
Also psu is a concern, no good having a 6-800watt if the 12v rail is pants.
And yes it is stable, been running it on vista with a P45 and now XP with a X38 mobo.
Problems can arise from upgrading drivers if the old ones aren't uninstalled, but to be honest I've not had any issues with that for ages.

Hope this helps..

Its totally unstable and has a 76% fail chance... Or does it ?
