5970 + 5970 + eyefinity. Will it ever work???

[PoshPorcupine]

K, trying to find something common between those who have this issue.
i'm thinking mobo myself.

i have a gigabyte GA-EX58-UD3R rev 1 motherboard running both pci ie slots at 16x with sapphire 5970's

Maybe I'm missing something, but isn't the connection between us all that we have 2 5970's in crossfire + eyefinity? Are you implying that someone has actually had this configuration working?

[tepescovir]

K, i got another mobo.p6t se and moved the 2 5970's to it and did a full win 7 64 reinstall.
Again went through all the driver revisions, but still getting poor performance with crossfire enabled with eyefinity.

[tepescovir]

K, intresting, but jedi adademy works perfectly with crossfire and eyefinity, it even vsyncs at 60hz instead of 120 hz.

I believe it is because jedi academy is an opengl game.

Can people try out any opengl games that you can get to work with eyefinity and crossfire , it may invlove a widescreen fix to make it work, but we dont care if the fov or aspect is out. Just need to confirm that the problems are with the d3d driver instead of the opengl one.

If you have a suggestion of an opengl game/demo that seems to work for you I could give it a try and see if that is the case. It seems logical that it might work for opengl and not for direct3d since im sure they have different code bases. I'm also downloading the 8.74 leaked drivers to see if that works for me. I notice in another thread you mention it causes crashes for you, but a good sign that it seems to contain a fix...

Some members of the Guru3d forum have reported 5970 crossfire (yes: 2*5970) + Eyefinity to finally be working with 10.5 driver ! Quadfinity finally !
I will test tonight when I will be back from the office to confirm it.

The long wait may finally be over :D

[SiriusDragon]

Hmms... raw power of 480s, or Quadfinity (if it works) + PhysX. If the issue really is fixed then it's gunna make my decision making a whole lot harder :? 2 5970 + PhysX is *alot* easier & cheaper to setup & cool than a Quad-SLI 480 setup after all...

I look forward to hearing more about this development.

[X3R Kefran]

I have tested several games and there are good and bad points:

Pros:
- For all the games I tested, FPS with 2 5970 is at least what it was with 1*5970
In a way it was the minimum to expect.... but it is quite new as previously, 2*5970 resulted in very poor FPS

Cons:
- Scaling is quite bad in most cases (improvement is between 0% and 20%)
- 2 * 5970 generate a lot of heat and therefore, the cards need to be run at ref clocks (maybe not for everybody, but for me it is necessary)
-> There comes the issue, in several games, the FPS I get with 2*5970 is better than 1*5970 at ref clocks (725/1000)... but at the same level than what I get with my 5970 overclocked at 875/1250
So currently, there are only a few games where I will benefit from this new quadfire + Eyefinity support.

Globally my feedback is that 10.5 bring a great step forward but scaling needs to be improved for quadfinity to be interesting

[Dick Hard]

Same here, 2 5970's give about the same framerate, be it not as smooth as 1 card....so, i am still the proud owner of a 600 euro watercooled paperweight!
Ati,bring us 10.6 with phenomenal scaling please.....

[bowenac]

This is still and issue? Has anyone heard or talked to Dave about this? Just curious if he knows what is going on and or if they plan to fix the issue. Been seeing people on other forums mentioning the same thing. Hope they fix this for everyone, because it looks bad for ATI.

[SiriusDragon]

An official word from ATI would be nice :- Considering the lack of raw power in the 5xxx series, Crossfire is almost a requirement for high detail Eyefinity.

[tepescovir]

the 10.5 drivers do seem to help a lot on some games, all source, l4d2 is now using crossfire and eyefinity ok. but bc2 still broken,
Also the 10.5 drivers have broken vsync which no longer works, even with d3doverrider.

This is the last straw. i dont care if i get 150fps. its not nearly as smooth as 60fps with vsync. so i'm waiting another few days for ati support to get back to me with a fix or i'm binning my 2 5970's and 2 5870's and going to nvidia and staying away from ati. I am so sick of spending more time trying to get ati cards to work then actually playing

I understand your frustration... but hopefully you don't get banned for mentioning your going to go to Nvidia. For some reason they don't like it when people say that here.

Nobody has been banned or even considered banned for mentioning going to Nvidia. Heck, Paddy and scavvenjahh are using Nvidia cards themselves with TH and Ibrin did so earlier. Since you came here on WSGF, you have been lashing out at reps, mods, WSGF and members and its that which gives you warnings from several mods and even Ibrin.

What did you wish to accomplish by the post you just made here? It looks just like a troll post designed to stir anger.

I was simply trying to warn him, and yes I got banned for 2 weeks for giving my opinion on ATI drivers and stating I was going to go back to Nvidia, and that is all I said. Again I don't see anything wrong with my above post, if you have a problem with it you could have handled it like a mature adult and PM'd me. What did you wish to accomplish with your post to me? Looks like a troll post from you as well, everything you said about me is a lie. I have not make any lashing's at anyone on this forum.

Here is another thread from another forum where someone is having issues with 5970's in Eyefinity. Sucks because ATI is acting like there are not aware of this issue haha. Obviously they should be well aware of it if they did any testing at all. They asked him to provide them with other users who exp the same problem.

Here have a read.

You didn't get banned for 1 week (not 2) due to your opinion on ATI drivers or stating that you would go back to Nvidia (do you really think that anyone here cares what hardware you buy?). You got a week cool-off for the manners of your posting. Same goes for every warning Ibrin, me and other mods have given you.

Claiming that its because of your hardware preferences or driver preferences is bullshit and I really don't wish to spend more time on you regarding this.

"Warning" CoolMan=GCHQ= that there will be banning if he says he wants to go back to Nvidia is nothing but trolling and a direct attack towards WSGF.

[skipclarke]

Bowenac, you insinuation that people get banned for preferring NVIDIA is insulting and misinformed. As Tamlin mentioned, Paddy has always been an NVIDIA user and he's the only person I know to consistently have Quad-SLI of the latest cards. NVIDIA supplied me with my 7500 GX2 and my 9800 GX2, and I bought my own GTX 495.

We have often said that NVIDIA had better drivers. From early on NV offered aspect scaling on their notebook drivers, where ATI did not. The forum actually always recommended an NV mobile GPU for this reason. We often recommended the same thing for desktops, unless the users monitor had aspect scaling.

For a number of years the WSGF promoted the NVIDIA XHD branding in many areas on the site. There was an entry in the left nav:



The MGL had a column for "Max XHD Res". These were in the days when not every game supported 2560x1600. And, we tagged MGL game entries with three different XHD res categories. However, as NVIDIA dropped the initiative, we dropped it here as well. In fact, we actually kept it up for several years beyond their support (notice their site only lists up to 7-series cards).

But, you wouldn't know any of this, as you've only been a member for about six months. The reality (whether you can recognize it or not) is that you took a public shot at the WSGF, the Mods and me in particular (as the owner of the WSGF and the person who pics and directs the Mods). You take a shot like that publicly, then you can expect to have it addressed publicly.

Anyone who takes shots like this at me, my Mods or the WSGF can expect to be dressed down in the same manner. And, they expect to be banned at some point.

I'm not sure if you meant the line as a joke, then you should have tried to indicate it at that point. Even if that is the case, it would still a joke in bad taste.

This is all I'm going to say about this. All that needs to be said, has been said more than once.

[skipclarke]

Back on topic. ATI has acknowledged that there were CFX issues with Eyefinity. It took until Catalyst 10.2 to even get CFX and Eyefinity to work together. The 10.2 support was for "simple" CFX, and not Tri-Fire or Quad-Fire. I know that ATI is aware and working on it.

With regards to the low scaling, is there a possibility that 3x1 is CPU limited beyond CFX? You may really need a 3x2 or 5x1 (when available) setup to utilize the power of three or four GPUs. In my review of the Eyefinity6 I found that the E6 CFX scaled about 40% - 60% moving from 1GPU to 2GPUs on 3x1. I would expect doubling the GPUs again to produce diminishing returns.

[hunuok]

Thanks for the heads up.

If it's any consolation, Cat 10.4 & 10.5 WHQL gave performance similar to that of a single 5970 in Eyefinity. Much better than the slideshow in pre Cat 10.3 drivers.

However, it introduced the blinking DP issue. FRUSTRATING.

Back to 10.3s.

[Dreadloxxx]

sorry to bump and old thread but I am considering picking up another 5970 since the prices are dropping due to the 6xxx cards being released. Im wondering if the scaling has increased any now that we are on ccc10.11 and if i should expect a big enough performance increase to make it viable. most games play well enough with 1 card 80% of the time for me but that 20% is very annoying lol. Its when the framerates dip and i get the stuttering when i pan the camera in certain points of games. I play WoW most of the time so im looking for the best performance possible in it. I am looking to get the frame rate cap 99% of the time, like it is when i switch to a single monitor. Is that even possible at this point with the current cards and eyefinity resolution? thanks
