Display Port issue with R9 290x QuadFire / TriFire / CrossFire (NEED SERIOUS HELP)

Still no resolution from AMD? Might want to give this utility a try: http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU.

If you see multiple "detailed Resolutions" maybe having only one will help (you can always reset config if something goes awry). Or increase/decrease the pixel rate to see if that helps.

I'm recently switched from 1080P 120hz DVI-D monitor to a Seiki 50" 4k tv and had a problem (only on Crysis 3) where the monitor would go to 4k@30hz res mode, but game resolution was 1080p@120hz(image being displayed was 1080 as well so monitor was down scaling). The only way to fix it was to remove the 4k res using the utility, but side effect is not having 4k res available at all.

I will be probably selling the R9 290x and get GTX 780ti

I'm so ***** tired of wasting my time. I didn't buy 4 x R9 290x to be able to play only with the DVI outputs or HDMIs.

Can't say I blame you. I'd be mad too if my large investment wasn't working as advertised.

Yeah, expect issues when dealing with very, very high end setup as the market is probably so small/niche that understandable that testing of said setup is done mostly by end users. However, for displayport not working is unacceptable.

Look on the bright side, you didn't lose too much money in the exchange

Can't blame you. Have a soft spot for AMD (had a 6950 and a 7970), with their support for open source (OpenCL/GL...), but you shouldn't have to deal with stuff like that, not given how much you've spent...
As for NV, I'd go with EVGA. They have amazing customer service. Heard MSI is also great in that regard. You can also get something like the Hydro Classifieds, not have to get a separate blocks and all.
And this is probably a great time to sell 290X anyway (cheapest I've found in Canada).

I just got an Email from an AMD engineer today.

Hi Karl,



Your issue is being investigated at the highest levels by our Engineers. They’re currently reproducing your issue. I should have more information for you early next week.


Regards

(Engineer name)

Thanks Warsam71, you helped me keep faith.

Hello Karl,



I just received an email from the guys in Customer Service which have been working on the issue with Engineering.



They have identified the issue and are working on a solution which will be included in an upcoming driver release. To be perfectly honest with you we don’t know when this new driver will be released yet; but I will definitely let you know as soon as I find out.



Best,

Sam T.

Thank you very much :biggrin: , I hope it will take a month or less for a fix. :thumbsup::awe:

Wow! Glad to see some progress. Your quadfire troubles have been going on for far too long!

Keep your eyes peeled for any beta drivers.

Maybe I haven't yet had enough coffee, but I'm not 100% sure I know what you mean by '3D mode,' KaRLiToS. Do you mean any app with 3D rendering?

Yes, all games basically.

14.2 beta 3 doesn't fix the issue.

AMD support (Engineering) doesn't seem to have found a fix yet because they asked me if I tried other adapters.

Bought those cards on release date, they were all tested and running on water by the first week of November. It now been 4 months since release that I cannot use my cards like I intended to.

I'm still optimistic ...

Hey carlitos, there's a big thread on OCnet about DP adapters. Since my English is so basic and i'm so noob at eyefinity and DP adapters things, i asking you if you can find a workaround in that content.

http://www.overclock.net/t/721931/active-vs-passive-displayport-adapters-the-truth


----------------



And some guys at AMD forums are talking that who uses Crossfire needs Monitors with DP ports to get everything working right. Is like is not DP+CFX+Eyefinity the problem, but rather is Crossfire+DP adapter.



Edit: the posts i'm talking about:

Guy 1 that seems to found the problem:

buying a monitor with display port I hope this is the cure.

Problem 2: Crossfire is frying your active adapter. This is purelly speculation but I believe Crossfire somehow puts too much strain on the adapter causing it to crap out and eventually fry all togeather. That does'nt make much sense to me but it might be a possibility.

Problem 3:The adapter is fine as long as you use one GPU. The adater may work just fine but it will flake out with Crossfire used in conjunction. This may or may not be related to the the PCIe itself, due to the fact that a single 7990 utilizing internal crossfire works just fine as far as I can tell.

Notes:
Had this problem with 5870s trifire
System is substatially over clocked but have the same problem on normal clocks.

Guy 2 "solved" the problem changing the adapter:

I am not 100% certain, what the new patch did, but it something to eyefinity and 3 monitor setups.


On my HD7990 I've been running a 3 screen Eyefinity setup for 6 months using 3 identical mini DP active adapters and after the patch only 2 screens can managed through CCC.


CCC can see the 3rd monitor fine, it is just disabled. And it cannot be activated by any means.


I solved my issue by using a different mini DP adapter and suddenly I could use all 3 screens again. But that meant a return of the screen tearing that happens when you use different types of adapters. So for now I am happy to have 3 screens working again, but it is by no means a good fix, cause the screen tearing is horrible compared to before.

Setting up Eyefinity and the replacing the adapter with the old working one automatically removes the 3rd display from the eyefinity group.


My guess is that the new drivers (and 13.12 as well, tested that as well) look to the frequencies in each adapter to differentiate each screen, but if you have several identical adapters, it cannot differentiate between them and only use the standard 2 screens which can almost always be detected. Kinda dodgy description, so bear with me

It is solely an Eyefinity issue. But the problem persists after reformat/reinstall, so it must be driver related and something that worked pre 13.12 was removed in the subsequent drivers.

Guy 3 reporting Cat 14.2 identifying that DP adapter broke:

Just installed the 14.2 betas and its told me the problem ! when the game minimises now it says the mini display port is failing which means the active adapter is broken ! looks like il be buying a new one. Hope this helps anyone else if they have this problem !

Wow, props for bringing this thing to light, isolating it with troubleshooting skills, and getting a direct response and solution in the works from AMD.

Quad 290x LIVES!!!

good info for anyone considering 290x crossfire for eyefinity 1440p.

DP to DVI-D is broken. need native DP.

thanks.
