5870 Crossfire problem

I was on the beta vbios with the dell drivers (the new ones) bios A07, and after I flashed the vbios, although I didn't notice it until a day later, in GPU-Z under Crossfire section, it says Disabled. I went into CCC to try to enable it, and there was no CrossfireX tab! I then went into device manager, and saw that one of my 5870s had an error that reads "Windows has stopped this device because it has reported problems. (Code 43)". I've tried uninstalling/reinstalling drivers, doesn't help. Someone please help!!

 

Try Deactivating / Acvitating the card in the device manager once, the mini-symbol should change aswell, then reboot, the CrossFireX option should come back again in CCC. If not, uninstall Drivers via Catalyst Installer Express, and reinstall the drivers after reboot again.

 

No go. Disabled, Enabled, Rebooted, same situation...

EDIT: Unless you wanted me to Disable, Reboot, Enable?

 

it might be caused by a bad flash you could need to try to reflash the card

 

did you flash it as both master vbios? also, try the A02 bios from dell. let us know what happens.

 

So I should just try to flash again in the current state? Any special thing I should do? I read something about a DOS flash, should I do that?

 

What does the VBIOS Flasher tell you when you try again, mine say both are already flashed.

Also yes, Deactivate both Cards in Device Manager, Activate them right again, Reboot the System. Check Furmark or GPU-Z to verify CrossFire, if not go look into CCC again, Disable/enable Crossfire in there.

 

It was a bad flash, both cards are up and running thank you all!

 

One last question, did you use the Dell Installer running again, if so how did it look like? Was 1 card not flashed or both cards, or did you do it manually in dos?

 

I believe the one card had an error halfway through, so just one wasnt done right

 

Oh okay, thanks. Good to know, it works with one card / second card only.
