Hi.

I got my second 7950 yesterday and right away I noticed a slight flicking when I was playing COD4 and then today I noticed it more when I was going to play DiRT 3 with a friend. Reinstalled latest drivers from AMD site, nothing. Disabled crossfire and the flickering was gone, re enable and it's back.

Currently downloading and going to install latest stable.

Anyone else have any ideas?

tldr; screen flicker with crossfire enabled, doesn't flicker when not enabled

Try using vsync. That's what I did for the three hours I got Xfire to work before switching to the green side.

Vsync has been enabled for both games, AMD drivers are beginning to royally piss me off anymore.

Try a different cable? Like hdmi or displayport?

Was using HDMI, switched to DVI. Still nothing. Also disabled ULPS.

Going to stress the one GPU tomorrow on it's own, see what happens.

I'd test your new GPU first seeing as your rig was working fine before you put it in. Also test each PCI-E slot with each card and swap the card positions over.

might not be a driver issue, might be a bad card!

Did it when I got home, no flicker, card ran find. Put them both back in with brand new Corssfire bridge, still flickering. Has to be driver issues...

Are the cards overclocked? And did you enable the second card in CCC? Besides that,there are flickering issues even with single 7950's and 7970's in COD,and Dirt 3 has multiple issues with pretty much anything installed on a PC!!!! Also,what resolution are you playing at?

They are not overclocked, one is underclocked slightly to run at the same speed of the other, same card slightly different model. What do you mean by enabled in CCC? If by that you mean crossfire ebabled yes, when crossfire is enabled, it flickers. I'll try another game other than those 2.

 

[Grmadness]

Ok, you can run the cards individually on same settings to see if there are differences in performance, if yes, then there is a problem. Might be the slhghtly different model though that is causing the issue. And when you say it is slightly underclocked,is it an OCed edition?

Try playing newer games like Hitman Absolution, far cry 3, BF3, may be the drivers is not working well with older games

I'll try a game on each I'm too frustrated right now. Not to my knowledge is it an OC'd edition, my original card is clocked at 800MHz with a max of 1100, the new is stock at 900MHz, with a max of 1200, I just tried this late last night. I'll OC the old one to 900MHz and see what happens,

Didn't see multi quote at first. I just tried Sleeping Dogs and the flicker was there, played FC3 last night and the micro stutter was so bad it was barely playable.

I would also try this

http://www.overclock.net/t/667144/crossfire-disabling-ulps

And it would be prudent to download the latest CAP for your cards,not the actual drivers,but the Catalyst Application Profiles,they usually contain updated crossfire profiles and hopefully fix bugs as well.

Hope it helps. Cheers.

have you using a different crossfire cable?

also might want to try a clean wipe and a fresh install of drivers:

You'll need two free tools - CCleaner and DriverSweeper. You'll also need to know how to reboot into safe mode, and to be able to use 'common sense'.

Disable Eyefinity groups, Crossfire, if enabled
Optional - Enter Device Manager: Uninstall Display Adapters and check box for 'Delete Device Driver'
Add/Remove Programs: Remove currently installed Application Profile updates (if installed)
Uninstall CCC and Display Driver, using Catalyst Install Manager Custom mode (Don't express uninstall if you have an AMD Chipset)
Reboot into safe mode
Run Driver Sweeper for ATI Display Drivers, don't reboot.
Run CCleaner for Registry - run Analyze and only select ATI entries for removal.
Delete the following folders (applies to Vista/7)
SystemDrive:\ProgramData\ATI
SystemDrive:\Users\username\AppData\Local\ATI
SystemDrive:\Users\username\AppData\Roaming\ATI
Reboot to desktop, run Express install on desired Catalyst driver & reboot if prompted.
Install the latest Catalyst Application Profile.
Re-enable Crossfire; re-create Eyefinity groups; Overdrive/CCC Profiles

Thanks, have tried a different crossfire bridge, gonna try the other things you said now, will report back results.

Ok, and try to run both cards at their stock speeds,don't underclock. And as a last resort, I would switch the cards on the PCI Express sockets. That's the end of the line,my knowledge ends here. Cheers.

Have you tried an older driver? The 12.10 and 12.11 work very well. As was posted already, be sure to completely remove the old drivers.

Tried the older driver, same thing. At this point I'm done, returning the card and selling my other is more than likely what I'm going to do.
