Catalyst Driver Performance Progression / HD 6990 QuadFire

For me at least these releases are not going in the right direction.

All 3DMark Extreme tests were run within the same 24 hours and on the same and hardware with latest 12.7.CAP3 profiles. Catalyst manager was used to uninstall drivers and Crossfire setting was re-enabled (toggled) prior to each test.

Steps for Creating a Custom IL-2 Sturmovik Cliffs of Dover Application Profile

I was having severe stutters and extremely low FPS with my crossfire setup. Creating a custom crossfire profile greatly improved this to the levels before the patch or even better! I am using 12.4 drivers with the latest CAP.

With this tweak I am seeing ~75% improvement in FPS and a significant reduction of stuttering!

1. Open CCC, click on 3D Application Settings, and scroll down to the section called “AMD CrossFire Mode for 3D Applications”. Select option: “Use AMD Pre-defined Profile”.

2. SelectLostPlanetDx10.exe application profile.

3. Scroll back up to the top of the Application Profiles section and click <<New Application>> and Save.

4. Find COD folder “C:\Program Files (x86)\Steam\steamapps\common\il-2 sturmovik cliffs of dover” and open Launcher.exe.

5. The new profile will look like this. (It may help to reboot.)

Best Drivers for Crossfired HD 6990s (Quadfire)

I am running dual HD 6990s. The best drivers for me were 8.940.0.0 with included caps.

X7319 –> http://3dmark.com/3dm11/2548742

Everything else both newer and older scores in the low X5000 range. Yes, I had tried every single one. the increase is evident across the board, both gaming and benchmarks.

Anyone with similar setups had different experiences? Please post your results and driver versions.

Problem solved!

Update, Shamino and the team from Asus were able to replicate the problem. In short, it was caused by out of spec displayport cables. Pin 20 was used, but should not have been connected. It was leaking voltage into the video cards.

Thanks Shamino, Raja, and Mason for helping to resolve this issue! It is so rare nowadays to get this type of attention and support from a large corporation.

Great team Asus!

New Theory – displayport cables are not in spec

http://rog.asus.com/forum/showthread.php?9084-Rampage-IV-Extreme-00-Code-After-Shut-Down/page9

Apparently according to the VESA DisplayPort Standard (Version 1, Revision 1a January 11, 2008) the pin  number 20 must not have a wire. So the next thing on the list is testing and replacing of the displayport cables.

A 30 step program…

For those who are curious LOL

1 PC is running @4.5 GHz / Eyefinity w/3 monitors via 3 DISPLAYPORTs

2 execute windows shutdown

3 bios button does not work

4 remove one DISPLAYPORT

5 bios button does not work

6 remove second DISPLAYPORT

7 bios button now works!

8 unplug both PSUs

9 connect one of monitors via DVI

10 power both PSUs

11 bios button still works!

12 boot up @ 4.5 GHz

13 no code 00

14 execute windows shutdown

15 bios button still works!

16 repeat steps 12 – 15 – no issues!

17 execute windows shutdown

18 remove DVI

19 bios button still works!

20 plug in second DISPLAYPORT and boot up

21 no code 00

22 execute windows shutdown

23 bios button does not work

24 plug in third DISPLAYPORT and boot up

25 code 00

26 unplug and power drain

27 boot up

28 code 00

29 unplug and power drain

30 boot up

31 OC failed message

32 F1 and F10 save

33 boot up @ 4.5 GHz / 3 monitors via DISPLAYPORTs

Ongoing … Asus suggested either defective displayport cables or defective Asus VE278Q monitors

Asus suggested it is a DC voltage issue caused by either defective cables or defective Asus VE278Q monitors.

I respectfully disagree:

In my opinion it is not the cables for the following reasons.

All three cables or all three monitors must be bad because I was able to duplicate this issue with different variations of cables and monitors.

I also duplicated this issue connecting two displayport cables and one DVI cable and two DVI cables and one displayport cable.

Same reasoning for ASUS monitors – it is either the systemic flaw with all Asus VE278Qs or something else.

A workaround of powering of monitors during post does not work. ASUS monitors do not support hot plugging displayports. Doing so results in blank screen.

I am still hoping that Asus will still try to duplicate this in their lab…

Testing continued…

Removing monitor power during post does not resolve issues.

If I execute Windows soft shut down and prior to post remove the power (unplug ac) form either all or any two of three monitors then I can post and switch BIOS. It also works when I unplug any two or all display ports.

Just softly shutting down my system without unplugging or removing monitors/displayports results in the code 00 and the inability to switch BIOS issues.

I’ve also tried mixing connection types (i.e. one DVI / two display ports and two DVI / one display port) resulting in exactly the same issues.

Enabling “wake on” options in BIOS did not resolve these issues.

My monitors are ASUS VE278Q.

Same Eyefinity setup functioned perfectly with my prior Asus ASUS P6T DELUXE V2 motherboard.

What are next steps? Will it be communicated to Asus engineers?
