So guys, I have a small update which is almost conclusive according to AMD.

(By the way, I'm pretty happy of the service I'm receiving from AMD, I don't feel left alone)

Hello Karl,

I hope you had great weekend.

I have good news for you. We have found a solution to your problem. It turns out the issue had to do with the adapter you have been using. After a few tests, the team has found a different adapter that will resolve your problem; which is the Bizlink KS10008 Diplayport to Dual Link DVI-D active Adapter.

I have already gone ahead and ordered the part for you and plan on shipping it to you as soon as I received it (should be by the end of this week). Could you please email me your home or work address?

By the way, would you like the game code(s) I’ve mentioned in my last email? I’ll be more than happy to email them to you – just let me know.


Best,

Hi XXXX,

Thanks and yes I had a great week-end .

I'm pretty happy you have found a solution but are you 100% it will solve my issue?

My adapters ( the UltraAV® Mini DisplayPort to DVI-D Dual-Link Adapter ) that I used with a Display Port with Mini Display ports, is working on many combinations of cards.

-Trifire HD 6970
-Quad Fire HD 7970
-Single card with R9 290x
-GTX 780
-GTX 680

I don't know why it doesn't work with Crossfire R9 290x (or trifire or Quad)

The Bizlink you mentionned is the exact same adapters as mine, except rebranded under the name of Bizlink. They also have the same firmware if I remember correctly. In fact, they are both on the AMD Hardware compatibility list.

My address is
XXXXX
XXXXXXXXXX
XXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXX

I will give it a try and cross my fingers.

Thanks

Karl

So to be clear, my adapters work with all these setups here

-Radeon HD 6970
-Radeon HD 6970 CrossFire
-Radeon HD 6970 TriFire
-Radeon HD 7970
-Radeon HD 7970 CrossFire
-Radeon HD 7970 TriFire
-Radeon HD 7970 QuadFire
-Radeon R9 290x
-Zotac GTX 780 Reference
-Zotac GTX 680 Amp Edition
-MSI GTX 780 TwinFrozr Gaming OC


But Doesn't work with these
-Radeon R9 290x CrossFire
-Radeon R9 290x TriFire
-Radeon R9 290x QuadFire


Also, this is my adapter



And this is the adapter they will send




I hope it will work.

Tell me what do you think.

The BizLlink are the ones i use.

I hope it works for you mate. Props to AMD, assuming it works.

Props to amd for sending him a £75 cable!!

It's the same adapter I used when I ran 120 Hz Eyefinity/Surround

That reminds me, need to stick it on the MM

Good luck with the cable.

Glad its hopefully all sorted and great work from AMD sorting it for you !

Ok, so today and yesterday I tested the Adapter I received from AMD.

It's this one



It is the Bizlink KS10008-131

This is what I found on the Accell web Page about my own adapters.



So in conclusion, it's 100% safe to say that they sent the same adapters as mine.



They also have the exact same firmware on each of them.



I also had a small present from AMD, which I will wear this week (Sam is awsome)

So, now what I did to test.

First, I formated my hard drive to be sure that there is no left overs. First thing I tried is Run my Quad Fire setup on a single DVI monitors

-QuadFire 290x + Single DVI Monitors = PASSED

Then I tried QuadFire 290x on a Single DP adapter monitor

-QuadFire 290x + Single DP adapter monitor = FAILED

So in conslusion of those tests
-every cards are working fine
-motherboard is working fine
-every PCIe slots are fine
-No power issues (also tested each wires of my PSU to verify the stable voltages)
-DVI outputs are fine

So I proceeded to test each single cards individually with the DP adapter monitor

-First Card + DP adapter/monitor = PASSED
-Second Card + DP adapter/monitor = PASSED
-Third card + DP adapter/monitor = PASSED
-Fourth card + DP adapter/monitor = PASSED


So in conclusion to those tests:
-Every cards display port outputs are working just fine
-Every adapters are working fine (the three of them)
-every monitors are working just fine


Then, my next steps were to try every combinations of CrossFire with the DP
I tried :
-Card 1 and 2 (crossfire) + DP = FAILED
-Card 1 and 3 (crossfire) + DP = FAILED
-Card 1 and 4 (crossfire) + DP = FAILED
-Card 2 and 3 (crossfire) + DP = FAILED
-Card 2 and 4 (crossfire) + DP = FAILED
-Card 3 and 4 (crossfire) + DP = FAILED

Between each of these tests, I was reinstalling Windows 8.1 to be sure that there is no crap and was trying different drivers from 13.11 beta 6 to 14.3 beta 1. And sometime trying more than one drivers on a single combination.


Then, my last test, which is one of the most conclusive was to test QuadFire 290x with eyefinity but with the DP monitor unplugged and only the DVIs outputs. So the resolution was 5220x1440 (eyefinity with two 1440p monitors)

QuadFire 290x + Eyefinity Dual 1440p monitors = PASSED

Metro Last Light Benchmark 5220x1440




So my conclusion is the same as 3 months ago

CrossFire (or tri or Quad) doesn't work with the display port outputs

My only way to be 100% sure of that is get some GTX 780ti SLI to test but keep in mind that the same system (exactly the same system) same monitors and same adapters were used with
-Trifire HD 6970
-QuadFire 7970

With no issue

Ok, I uploaded a Video of 4 tests that I did to illustrate the issue.

First test:
-TriFire (3) 290x with Eyefinity ( cards 1 - 2 - 3 )= Out of Sync

Second test:
-CrossFire (2) 290x with Eyefinity Using cards 1 and 3 = Out of Sync

Third test:
-Single (1) 290x with Eyefinity using card 1 = Runs Pretty Fine

Fourth test:
-CrossFire (2) 290x with Eyefinity using card 1 and 2 = Out of sync

By the way, each tests were done on EACH freakin combinations you can imagine with four (4) cards in QuadFire.

Each cards were tested individually like in the THIRD TEST.

Enjoy there is a little suprise at the End

Hi everyone, I wanted to say thanks for you time and effort here firstly, very well put easy to understand thread

I also have 2560x1600 monitors 4 total and 1 4k (60hz) monitor.
I have 7 r9 290(x) total. 5 of witch i have used to test eyefinity.
I have tested 8 adapters
- 2 Accell UltraAV B087B-002B DisplayPort/DVI-D Dual-Link Adapter (no display even in post. also tested with usb wall power unit.)
- 2 VisionTek 900639 DisplayPort to Dual Link DVI-D Active Adapter Cable (tested 2 of this units both gave me display with corruption reguadless of screen resolution.)
- 3 StarTech DP2DVID2 DisplayPort to DVI Dual Link Active Video Adapter Converter - DP to DVI-D - 2560x1600 (only one that works at all. If video card is severly down clocked will also work in 3d mode provided gfx card is not being taxed to heavy.)
- 1 BizLink BZL-KS10008(B) (no display even in post. also tested with usb wall power unit.)

Displayport works great for 4k but i have had 0 luck getting all 3 screens up and running. I have tested on 3 different computers now with known good parts.
- x58 1200w pc power and cooling psu.
- x79 1350w thermaltake psu.
- 990FX 850w thermaltake psu.

Does not work in single or Xfire config. AMD has gotten back to me (slowly) after a number of phone calls and emails, with some crap about changing my want levels in my Profiles.xml (did nothing). Sapphire is impossible to call (apparently). Going to see if I can try and get a new vbios from gigabyte or XFX (AMD said I may need to rma cards and get new vbios) witch only furthers my suspicions about this being hardware related or more so voltage regulation likely due to under volting to keep with in the 250w tdp, so if anyone knows how to mod a bios and bump up the imc regulator that would amazing! even if it meant down clocking to stay under the 250w tdp.

At any rate keep it up let us know if you learn anything new!
