CFX trouble, out of ideas ... can someone help please!!

post #1 of 7
Thread Starter 
Hi guys, so this has been killing me as of late and I'm tired of banging my head on the wall.

My 2x 6950's just cannot work together in crossfire. I'll be playing BF3 for maybe 15-25 minutes (~90 fps on ultra) and then my whole system just freezes and I have to do a hard reboot.

I don't get it, the cards work absolutely fine by themselves (shaders unlocked, OC'ed to 900/1400 @1.15v) on either PCI-E lane, so I know it's not an individual card or slot problem. I really don't play many other games, but it also happens on MW2, MW3.

In crossfire, the temps are very reasonable since neither card goes above 65C, so its not a heating problem (use msi ab custom fan profile).

I have ULPS disabled in regedit, and ALL stock settings in CCC (no 20% powertune).

Also, just in case there's a doubt on the OC, I've put both cards back on stock clocks with locked shaders and the problem still occurs.

I've tried to install the drivers with one card only, and then plug the 2nd card in, and also with both cards in at the same time.

This has been happening since 11.5 drivers I believe and I've tried everything (including CAPS) up to and including 12.1, but still no luck.

The only thing I can think of is maybe my PSU is coming up short but its a pretty hefty 850W supply. I'm really hoping I don't have to reformat windows. Are there any other ideas out there? Thanks for any help!

Try this to eliminta drivers related issue.

 

  • Uninstall all tweaking applications such as Afternurner, Trixx etc if you have it in the system.
 
  • Uninstall Catalyst package and CAP. Select "Express Uninstall"
 
  • Delete these folder;
  • C:\user\Program files or (x86)\ ATI or AMD.
  • C:\user\ProgramData\ATI or AMD (need to show hidden files).

 

  • Set the UAC to minimum.
    Go to Control Panel > User Accounts > change User Account Control Settings > move the slider to bottom > restart PC.
 
  • Clean it with;
  • (Run with administrator privilege. Some antivirus software will give a false positive. Let it restarts to complete the uninstallation - Disable UAC to install this cleaner).
 

 

 

This is right way to make sure ULPS is turned off;

 

Use latest MSI Aterburner 2.2.0 Beta 10. Make sure is stable with the overclock, otherwise, it will have problem too in crossfire.
 
1. Go to regedit (start > search programs and files > "regedit").
2. In drop down menu: find file > type "enableulps".
3. For ALL instances (keep pressing F3) change the "1" value to a "0".
4. Reboot PC.
 
You must disable ULPS then proceed to enable "unofficial overclocking" and never override Afterburner with Catalyst installation. Not the other way around. Make sure each card overclok is stable before put them in crossfire. Power supply and temperature will throttle the clocks and voltage too affecting performance. Make sure of that for crossfire to work correctly.

Have you checked all of your temps in GPUZ? Afterburner does not report every temp probe on the card.

I think this did the trick! So far so good playing BF3 for about 2 hours ... hopefully it stays good, thanks

That should fix it. Just can't think of reason why it shouldn't.
