Hi guys,

I have a new crossfire 7970 setup, I'm noticing red dogs on black backgrounds every now and then, very noticeable in Far Cry 3 but this seems a common issue on that game with this card.





Anyway to fix this?
 
Does it happen in safe mode? Tried driver change? Is it there when no driver installed vga mode?
Tried a different monitor, this just to rule out the display.

Edit
7980??
 
That used to happen on my old gaming laptop, the one which had new GPU's on no less than 7 occasions under warranty. They kept frying due to heat. I'm not 100% sure but I think that is a sign of a failing GPU
 
Take out one card if it's not there try the other until you can narrow it down to one card, if that doesn't work, try a new bridge.
 
Thanks.

I've noticed in Crossfire one GPU runs a lot hotter than the other one, is that normal? Might have a dodgy card. Bah.
 
One of the cards is incredibly cold and the one with the two monitors connected to is hot.

Temps at idle seem perfect normal apart from one is 40oc and the other 30..It's like one is taking all the stress and the other doing nothing. I'll try a new bridge.
 
Thats normal since you have two monitors plugged into it. That card will be working harder than the other one to display picture on the monitor. When idling that card is likely to be doing all the work (according to my very limited crossfire knowledge).

For your problem though, try as above. Does it still show in safe mode?
 
It quite normal for one GPU to be hotter than the other in Xfire isn't it?

Due to the fact one is using the hot air exhausted by the others, its normally GPU1 that is hotter as hot air rises and all..

Not sure about the dots though, try a new bridge and see if that affects it.. :)
 
I may have found the cause, one of the power cable's wasn't fully clicked in, took a big push to get it to sit right, now there's around 5oC between them and I can't see the red dots! Woo!
 
On desktop with multi monitors usually the top card stays 15C more than the bottom one, because the 2nd card is not in use.

When gaming the difference should drop to 2 to 8C (depending on your card fan and distance between them), if the bottom card still much cooler than the top one, probably the game is not using crossfire.

I had one card that was doing that, showing the dots and the problem was the card. (probably BGA problem)
 
This happened to me once, then lines started appearing down the screen. I had a faulty graphics card and needed a replacement,
