[Scuddoo]

Hi,

Got 2x 4870 with with the crossfire bridges installed and i can't see the option in CCC to enable crossfire.

I've uninstalled and reinstalled drivers, tryed older drivers. installed cards in different order etc

I have a P6T Deluxe V2 MB with latest firmware running Window 7 Build 7600
1000W PSU with the 2 6pin plugs for each card

This is the Hardware info from CCC

Do you need to enable crossfire within the BIOS?

[JoshMST]

Well, I guess first off you should install each card separately and make sure they work that way. Before you do that though, mark the different cards, and be sure to identify the one that is listed as "disabled". Once you have made sure that both work in single fashion, swap the placement of the cards so the disabled one is now the primary card.

Make sure you use the latest Cat 9.8 drivers that have been released today (at least I think they have).

I think Crossfire tab or whatever with check box was not there in earlier versions of the driver and they added it later with new driver version.

Both cards tested and work fine. Got the latest CCC.
Still no CF option in CCC.

have you tried attaching the monitor cable to the other card?

Do you need to enable crossfire within the BIOS?

No, as far as I know, requirements are crossfire cards that are working properly, crossfire cable, power supply that is feeding enough power and a crossfire motherboard and drivers or OS that supports it. After the requirements are satisfied the box should appear in the CCC to be enabled.

Which slot do you have the 2nd card sitting in?

[djotter]

Have you tried reversing the bridges (put the words around the other way), or just having one bridge?

[Scuddoo]

Yes I have connected a monitor to the output of the 2nd card and it is a clone of the output from the 1st card. Power is not an issue as the card displays a warning befor boot up if there is a problem. I have tryed reversing the crossfire jumper and also tryed 1 only. The cards are in the top 2 slots of the motherboard and is both pci-e 2.0. In the bios the only setting is for the 2nd and 3rd pci-e slot: Auto, x8 x8 or x16 x1. I tryed all 3 combos. Did I miss anything?

OK i just checked the Gigabyte website to see if they have anything... found a bios update for the card. Couldn't find any notes or info about the different bios versions but thought I'd give it ago (what have I got to loose)
So I did it one Card at a time. Did the 1st card rebooted still working... took it out and did the 2nd card and it still worked.
Put both cards in with 1 crossfre jumper and when windows came up so did a CCC with the crossfire option. YAY!!!!

Now to go test some games out...

PS
Thanks for all the posts

It's working now, good. You paid for I think so obviously it made sense to do what it takes to get it working properly. so, it's working now and it is corrected. I am satisfied.
