how to set it up?

[matsamas]

Hello everyone.
After some helpfully advices from some nice guys on the forum I ended up to crossfire my hd 7970 with and r9 280x.

I am also upgrading ssd so I need a guide on how to set up the crossfire like on Windows install I should have already plug both gpus? With the crossfire bridge or no?

Do I need to make changes on my bios before doing so?

I have a gigabyte z77x-ud3h mobo.
It supports x16 and x8 pci express 3.0

Will I be fine with this?

Tnx you all in advance.

I don't think you can crossfire a hd 7970 with a r9 280x? They both have to be the same chipset

They are and they do crossfire pretty well. Kinda sure on that.

Put the second one in the 2nd pcie slot and attach the power supply connectors. Join the cards with a xfire bridge.

Start the pc.

Then go into Catalyst Control Center. It should have already enabled crossfire automatically.

Yea but on Windows installation does it matter whether I have one or both gpus plugged in?

No. Windows still works the same.
