PC Related.....Second Card Showing Up As Disabled So Can Not Enable ATI crossfire

[a98pmalcolm]

Ok they used to be crossfired but not anymore. I havent no luck tonight. Im feeling Such a noob with PC's at the moe

 

Ok in device manager it shows there are 2 HD4850 cards, In GPU-Z there is 2 but crossfire is disabled.

In CCC there is no option for enable them.

I think it was the update that made this happen so i reinstalled and still no luck. Both cards work perfectly and are powered up

Here is what it says in CCC information:

Update the ATI drivers.

Does your mobo support crossfire?

Have you got BOTH crossfire clips attached. Take a pic of your crossfire setup inside the case

[The-Plethora]

You still have the crossfire connector on right? I think some newer boards support crossfire without the connector.

[DamanC]

Crossfire and SLI only needs one 'clip' attached not two.

 

Enabling and disabling crossfire is done in CCC. Make sure you are viewing the advanced version. Still no go then get all the drivers and CCC off and reinstall, you may need to wipe the drivers too, and reinstall with the latest or a different driver.

 

Unlikely but your 'clip' aka bridge could be garffed or worse one of the cards.

 

Oh, and update the BIOS on the second card to at least match the newer BIOS.

[TonytotheB]

One? I kept putting two on... and go-faster-stickie-tape

[DamanC]

The go faster tape will help tremendously but having two bridges wont do any harm

Thanks for the reply guys.

 

Crossfire was enabled before this update i did. So mobo deffo supports the feature.

 

I was considering updating the drivers but i hear is real risky.

 

Normally i have the crossfire tab in the CCC advanced but after the update the tab isnt there and there not crossfired no more.

 

Will look into updating the drivers and as requested a pic:

All sorted now.

 

Ok what i did was totaly remove anything to do with ATI.

Then tryed to reinstall CCC. After installation i got an error with the ati driver fail.

Low and behold blue screen

Went into device manager and updated both card drivers that way.

Restarted the comp. And the crossfire tab was there and it was enabled, also with the info the 2nd driver is confirmed link not disabled.

 

Now the drivers are correctly installed lets see if i get blue screens.

 

Many thanks for the time again guys, this is simple stuff and im finding it all a rite challenge atm.
