For christmas, I received a second video card and a motherboard, so I could crossfire. When I assembled everything, I went into my drivers, installed all of the drivers for the motherboard, but the crossfire settings for Crimson were frustrating, so I installed the latest Version of Catalyst and checked "CrossfireX" (I also uninstalled Crimson) To my surprise, I was still getting the same scores in 3DMark firestrike, and getting the same frames on GTA V. Even though I have the card checked as crossfire on AMD Catalyst, it says Crossfire disabled on speccy.
It's not that Crimson is bad. but the drivers are so new, especially since AMD deprecated Catalyst, that the CrossfireX Features aren't even available on Crimson.. though they are coming.
If you wish to use Crossfire you have to stay with Catalyst for the time being.
I dont really get an option with the 990fxa, the top 2 slots are right next to eachother and the bottom one is the only slot I can fit the card in. All 3 are 16x though
I get probably a 90% success rate with this. The few times it fails are when three cards are involved and one is not the same model (I.E. 290 and two 290X in Trifire, the 290 usually wants to be the primary display adapter before CrossfireX works.)
Edit: @Kat beat me to the punch on the swap cards thing, didn't see that had been posted while I was typing up my post.
Damn, still not working. :/ Could there be a possibility something having it to be with an older model of the card that's causing the issues? The currently bottom slot card is a few months older then the top one, which they made a ton of revisions (updating it with a dual bios switch and a new heatsink design, should I check whether or not the bios's match up?
All 290Xs come with a dual BIOS. That shouldn't affect anything, but do check that both are in the 1 position. This is the default GPU (Non-Uber) vBIOS.
I'd take another step back in drivers at this point to 15.9 or 15.7. I just had a chat with a friend who has dual 290s and is using Crimson 15.12, he's not having these problems.
Also give GPU-Z a quick glance and see if it reads CrossfireX.
I trust that more than Speccy. Run a simple benchmark if you have one (Unigine Heaven, Valley, Passmark, Metro, Tomb Raider), then disable Crossfire and run it again. I'm starting to think something is weird with 3DMark.
chipset drivers can be had here...... http://support.amd.com/en-us Click on drivers support. Pick the correct os that you are using. Go to optional downloads and you should see a listing for chipset drivers.
Im really confused on this, I downloaded the chipset drivers, and it reinstalled crimson. NOTE IM GOING TO INSTALL IT, INCLUDING 15.9.1 AND SEE IF IT WORK. Thank you all for your help with this, you've all been so helpful so far.
Should only install the installer. Which does look like your installing Crimson but it should be only install the chipset part and not the whole Crimson package.
