Amd Crossfire problems with 7970 and 280x

[Fine Evo]

So I previously had a Gigabyte 7970 oc wish ran without problems. For Christmas I got myself a Gigabyte 280x oc to go with It as I couldn't find a 7970 at a decent price. I've had the graphics card installed for about a week and here are some of the problems I've encountered.

Can't play Battlefield 4 with crossfire enabled, although I've heard many people are having the some problems from both the red and the green camp. Unplayable, weird texture glitches and 90-100% CPU usage, therefore freezing.

Can't play Skyrim with crossfire enabled, some of the textures bug out and make triangle shaped spazes. I've looked for fixes with no luck.

My 280x is identified as a 7900 series, am I downloading the wrong driver? Should I be getting the R9 series driver or 7000 series? They might be the same driver, haven't checked. Which card should be my ''main card'' and how do I change which one is my main one (or does that depend on what PCIe slot its in?)

Can't play Rust with crossfire enabled due to texture spazzing. Not a big deal as one GPU is enough on high settings but not ultra.

Some other games have trouble but I don't really need crossfire for many other games. 

At this point there was no point in getting a second GPU as I can't utilize it in any games. I've tried beta and non-beta driver with no luck.

 

Specs:

8GB RAM

i5 3570k @4.4GHz

7970/280x crossfire

850 Watt 80+ Silver

 

If anyone can give me and advice/fixes for my problems that would be greatly appreciated.

Thanks,

Cody

Check which drivers you have installed.

Are either of the cards overclocked?

I have 13.12 win7 64bit drivers and yes they are overclocked, should i clock them at the same speed and give that a go?

That could be causing frame pacing issues, but in a dual GPU setup - SLI or Crossfire - I thought the two cards run at the slowest speed between them.

 

As for selecting the primary graphics card, that should be as simple as plugging the monitor into the graphics card you want to prioritize and changing the master processor to the second GPU in MSI Afterburner. I haven't done that myself, but the option is there.

I don't know when this happened but my 280x now shows as a R9 200 series inside AMD Catalyst control center

Skyrim doesn't have any crossfire profile. So even if it were to work with crossfire, you wouldn't see any performance boost.

That's because the 280x is just a 7970 rebrand.

an R9 280x is a R9 200 series card....

You can CF 280(x) olny with 7970 Ghz edition .

You may wish to update the BIOS of your HD 7970. Also, run them at stock clocks. The overclock may be causing frame pacing issues as others have mentioned.
