1st time X-Fire setup

post #1 of 18
Thread Starter 
I'm sure this is a duplicated thread but please bare with me. I just ordered a 2nd 6870 and just wondering what the crossfire setup process is? Do I need to enable something in Bios, OS, both? What about drivers? I'm currently running 10.12 with no issues but do i need to reinstall with xfire? Also, last but not least, I have a current OC on my 6870 of 1000/1200. Should I set that back to stock for cross fire or should I attempt to get my 2nd card at the same OC as well? Thanks in advance!!!

Oh and one more thing, I hear a lot about microstuttering with crossfire. What exactly is that and is it really common?

With those cards you will want to:

1) Uninstall the drivers from Control Panel
2) run driver sweeper
3) reboot
4) Install 11.1a
5) install Crossfire profiles
6) reboot
7) go into the CCC panel and make sure that the check box is checked for crossfire, should be but I check anyways.
8) overclock... if you clock in CCC then you have to clock them both individually (there is a drop down to select the cards)
If you are using AfterBurner, then you will OC them both at the same time, AB is great for this reason.
9) GAME!

If that's your first card addition, you don't have to do anything but power down and slap in the new card and put on a the cfx bridge. Upon boot up the driver will pick up the new card and setup cfx. Reboot again for good measure. Enjoy.

There you go XD Actually all I did was just turn off my machine, put in my second cad and connect the xfire cable. Aftward turned it back on, went into CCC and turned on xfire.

Drivers are a lot smarter than you think.

I haven't done xfire yet, but it doesn't hurt to try his method. Its the easiest and if it works, then great..

If not, do other methods.

it's pretty simple.

install card.
connect bridge.
enable crossfire.
install latest crossfire application profiles.

there is no need to reinstall drivers.

If you don't reinstall drivers, CFX control panel does not show up. Maybe instead of uninstalling drivers, just reinstall CCC.

P.S. Don't use Driversweeper unless as a last resort. It can cause problems sometimes.
