Heard there is a bug with some MB (asus?) and amd cards in crossfire set ups.
However, new tech arc dosnt make it easier.

I am happy with my single card at 5040x1050 as it runs just fine.

Hi guys, this is a known issue and a fix is on its way. The computer may freeze when using two or more 79xx cards in Eyefinity. In some games it's very easy to reproduce, in others it may never happen. In my experience, this issue only happens with certain intel chipsets (X58 and X79). I have a Z77 computer that runs crash-free with the same cards that crash my X79.

The fix should be ready "soon" ;-)

oha....

so a Software fix will to this?
Or we need a BIOS update? When its somehow related to Mainboard.

I get this crash alot in The Witcher 2 and occassionally with Dota 2.

Good to hear about a fix coming. I've got the X58 chipset in a ASUS board from a couple years ago..and its been "freeze free" for some time now..With me it was just a problem cleaning out the old driver stuff and getting the second GPU recognized properly. But I still get some small hiccups using two 7970's in iRacing games. But that could be iRacing..They work..I'm just not sure all isn't better with just one card though?

Could be iRacing or some game configuration on my part..they have a lot of graphic choices in iRacing and I'm pretty new there.

Planning to get a new CPU and MOBO in the near future..Will be interesting to see if there's a change regarding graphics.

First, I am sorry I can't find any referances directly..

But some of the intel chip sets do have an inherant problem mostly is has to do with where the PCIe bus is connected. As 1 channel is hooked to Northbridge/directly to CPU and other channels hooked to South bridge. (or did I get North/South mixed?)

Anyway, the up-shot, you will not get 3 x16 slots going the same way. Some have 2 muliplexed on the channel direct, the 3rd will still be hung out on the other. Then there are those that do not multiplex the direct channel and would leave 2nd and 3rd hung out on the other bridge.

AMD boards have them all "going the same way", even the higher end boards with 4 x16 slots.

There is a post here somewhere with one guy getting "micro stutters" driving him nuts. So dragged his triples(nVidias) over to a buddies runing ATI triples and ran them there. They ran perfectly smooth with buddies Phenom II 6x. The board had 4 x16 slots, not the newer PCIe spec' mind you. But they rocked.
He went home and dumped the Intel setup.

Try a search here for micro stutter..

I come from a racing back ground, and it did not matter how much power you had as much as having all cylinders firing evenly.

So have closer look at where yer PCIe bus is going. For dual setups the multiplex setup should be fine, other wise you would need to put them in the other/Southern slots. Same with the doubled up cards, obviously giving you quads.
Tripples are a problem on intel. Not sure what is curently availible.

There may be tweaks, like runng all on the older x16 spec' rather than mixed.

Thats what she said!

Did you try it out yourself?

I've downloaded 12.11b11 and CAP2, but i don't plan on a correct installt, i^ll just overinstall (did the same with the last few Beta drivers. never had problems!)
So i wonder if my game still crashes in Eyefinity Crossfire. But sadly i don't have the time to test it out tonight... first date would be this Saturday.... gaming night inc!

Yes, I have been testing this driver over the weekend and the problem hasn't happened again. I have also collected reports from other forums and everybody reports that same good news.

So glad to hear it! I've been having intermittent (from once per day to several times per day) non-recoverable hard freezes when gaming since I got my 2 Radeon 7950s a few weeks ago. When they occur, whatever is being rendered gets frozen on the screen and the audio begins a short stuttering loop of whatever was playing at the time. They've occurred in Crysis 1, Battlefield 3, and Borderlands 2 pretty consistently. I'm also pretty sure I've gotten them in Sleeping Dogs and Hitman: Absolution. I'm running a core i7 920 Bloomfield with an Asus P6T, which is indeed an X58 chipset.

I never had any issues with 2 4870s or 2 5870s in Crossfire on the same rig and I've been trying every damn thing I could to fix the issue with the 7950s in Crossfire: updating the motherboard bios, trying different driver revisions and CAPs, swapping PCIE slots, trying different crossfire bridges, and using different power cables from my modular PSU. None of that fixed my issues, though.

I updated to the 12.11 beta 11 AMD drivers and the corresponding CAPs last night and got in a few hours of Far Cry 3 without any hard freezes. But, I hadn't tested Far Cry 3 on the previous drivers so I don't know if it would have exhibited issues or not. I'll definitely do some more testing under Crysis, Battlefield, and Borderlands tonight to see if they've still got issues or not.

Now just stay on top of AMD so they don't patch it back out in the next release Thanks again!

Edit: Just wanted to add that I did 50 loops of the Crysis GPU benchmark with the new drivers and didn't hard freeze like I had been under 12.6 through 12.11 beta 8. So, that's encouraging! Given that the hard freezes had been intermittent, I'll continue testing and report back again later.

Edit 2: Day three with the new beta drivers and still no more hard freezes. I've run through another 50 loops of the Crysis GPU benchmark and played a couple more hours of Far Cry 3.
