AMD R9 280 Crossfiring Problem

[TheNoobHimself]

So I've crossfired my cards and I'm getting less FPS than before, I'm not quite sure what it is, I have an 850W platinum PSU, AMD FX-8320, and a ASUSTeK COMPUTER INC. M5A97 R2.0 motherboard.

Some games don't support crossfire, and cross firing can sometimes cause trouble with said game, causing fps to drop.

[TheNoobHimself]

Do the games you play support Crossfire?

Yeah, they do.

I just checked and they do. I play Shadow of Mordor and CSGO mostly.

First, make sure you have uninstalled and reinstalled the drivers and Catalyst. Always restart the PC when going enabling or disabling crossfire. In the gaming menu under 3D options go to the bottom and select the profile for the game you're playing. Usually easier to use the search bar directly over the list. Hope that helps

I've done the drivers several times, and I don't see a profile for any game in 3D settings.

Is there a way to check?

All the way at the bottom. You'll see the crossfire profile set to default. Select that and choose, says something about game profile(away from my rig), then you get the option to choose a specific profile. It's harder than it should be and hopefully Crimson fixes this. But it's there at the bottom. And make a separate profile in Catalyst for each game you play so you don't have to do this every time to play. In the 3D menu you'll see a + sign to the left between the two menus. Hit the plus sign and open the exe launcher for the game you want to create a menu for. Then each time you play Catalist will use those settings automatically

Yep! Now go to the bottom and change CrossfireX from default to the the games profile. Might be more than one, I always pick the newest and go from there.

Question - is your motherboard equipped with 2 PCIe 2.0 X16 slots? If no - that's your issue

the 8320 is a pretty old cpu for now, reccomended gpu to use with are up to a 960/380/380x/280x, there are little bottlenecks when using r9 290 /390 -gtz 970or better

if you are using 2 r9 280x, there will be most likely a bottleneck. Try overclocking your cpu a little. if you see a perfromance increase, the 2 gpus are getting bottlenecked

Ok, I did that, is that it?

Depends on the game. You can set the cores used with Fallout 4 and this allows the 8320 to perform better than a 4690k. Don't fall for the trap of all or nothing. It's game to game, task to task.

There are just 280s, not 280xs and ill try that too.

Play, see if it helps.

well, that is true, but only for well optimized games that can utilize all cores. Most games cant, but things seem to change

I just did it for Shadow of Mordor and it did help. thank you!

[TheNoobHimself]

And I'm also going to overclock my CPU some and see if that helps. Also is it normal for my second GPUs activity to be at 0%

Depends, could mean Xfire isn't enabled or that the second GPU isn't needed. If you have a max fps set then Catalyst will turn off the second GPU when you hit it.

Its enabled and I don't have the FPS cap on.

What resolution is your monitor and do you use Steam. If 1080p and yes then Steam will limit you to 60fps and Catalyst will respond by shutting down the second GPU. The second GPU should kick in instantly to deal with fps dips, If the profile is a good one.

yeah it's 1080

[App4that]

yeah it's 1080

Try a game outside of Steam if you have one. It's academic though as if it's a 60hz monitor everything over 60fps is a waste. Only thing to watch for is dips below 60 and in crossfire you shouldn't see them unless you're playing something like Fallout 4.
