[Solved]Bad Crossfire bridge???

post #1 of 6
Thread Starter 
What are the symptoms of a bad or dying crossfire bridge/ribbon?

I'm having the "no video display" signal whenever there are heavy actions on games and the display will recover. I disabled crossfire and only ran it with a single 6990 and I don't get the "no video display" but once in awhile, I'll get tearings across the screens. The minute I enable crossfire again, I lose video signal during heavy action. There are no artifacts and temps don't go above 42c. Drivers is 11.10. No caps.

I'm betting on a bad ribbon.
Is there a possibility my psu is not giving enough juice when quadfiring? I'm pulling 980watts on the wall. My psu should be able to handle that.

Edit: I'm running 1920x1200. No Eyefinity.
Edit2: Running with stock clocks 880/1250 and switched Bios switch with no effect.

Solution: It really was a bad crossfire bridge/ribbon. I went through my numerous gpu boxes and found the proper ribbon length and installed it. Immediately, my games were running smooth as butter with full quadfire capability. Overclocked my gpus to 1000/1400 and it is running smooth.

Edit: Grrr...Didn't test it long enough. I'm back to square one. I'm still losing signal.

Solution2: I changed too many things and I don't know what exactly fixed it.
1. Took out both cards and did a deep DataVac vacuum clean and its surrounding including pci lanes.
2. Did some cable management and made sure cables have enough slack.
3. Replaced the Rams with another set of triple channel 1600mhz sticks
4. Changed a few Display adapters with my backup DP adapters.

Hmmmmm, I think you can actually run your computer without the ribbon, it's just much slower. If anything, buy a cheapo one and see if it changes anything.

I've been using a single 6990 just to test my theory of a bad bridge but what stumps me is what is causing all the tearings. I even put Vsync on and it still tears like crazy. My temps are in check and I've used drivers 11.8, 11.9, and all versions of 11.10 with no success.

I just wanted to cover every angle seeing that I have problems with crossfire enabled and disabled.

I'm digging through my junk to see if I have any available crossfire bridge. Thanks for the help.

If you have a bad Crossfire bridge, in CCC the crossfire will be disabled and if you go to CCC diagnostic it will tell you to connect the bridge. Same goes for SLI bridge.
