290x crossfirex please help

Johnny_R · Jan 5, 2015

Hey all im a PC noob and would appreciate some help.

I bought 2 Radeon 290x asus cards and my mother board asrock z97x fatality killer is meant to support crossfire.

Both cards in I have installed latest drivers my screens are up but I don't see any crossfirex options in 3d settings. I tried googling and youtubing cant find anything.
I tried adding a game into a new profile under (gaming > 3d settings > Add) but that didn't give me anymore options.

I have CPU-z and I do see 2 drop downs options for video cards so I think both are being detected.

Is there an option to enable crossfirex or is it AutoDetect?

stressed out ): not sure what to do

Why didn't you buy a 295x2 instead and have it auto CFX? But sometimes I can't find that option either, but right now I have the Omega driver and I don't seem to have any issues at all with anything.

@lone becauase Im noob didn't know what to buy >< first time bought pc parts in 5 years. If I download omega drivers do I have to enable crossfire?

I googled them I think I already installed them.

How long ago did you buy these? Maybe you can return them and get a 295x2 instead. It's much better, but I can't exactly answer your question because the 295x2 is the only card I have for multi GPUs, so I've never had a bridged CFX/SLI, but there is a crossfire option in there and you have to enable it.

-Lone- · Jan 5, 2015

Did you bridge them with a N shape thing? Mine automatically Crossfire, so you may have to use a bridge for yours.

-Lone- · Jan 5, 2015

They should have came with your mobo or GPU, you'll need to connect them if you haven't already. If your GPUs are out of 30 days of return, then maybe you can sell them and get the 295x2 instead with doesn't require a bridge and has installed liquid cooling. So far they work perfectly with the new Omega driver, I haven't had one crash yet.

-Lone- :

Ehh.. You can't use a bridge with the r9 290x right..?

-Lone- · Jan 5, 2015

How would I know, I've never had it, lol. I have the 295x2. I'm just assuming that it needs one if that could be the problem.

Johnny_R · Jan 5, 2015

KenGrinsven :

yeah I read that it doesn't use a bridge. It should be capable of crossfire but I just don't see it in driver options

-Lone- · Jan 5, 2015

Well, that's nice to know it doesn't require one. Which driver do you have? Go to the very bottom of catalyst.

Johnny_R · Jan 5, 2015

driver 14.12 catalyst omega

this thread says to use older drivers because its a common problem after 14.4 should I try this?

Hmm, not sure why it's not there, what's the rest of your system by the way? Like CPU? Doing some Googling.

Johnny_R · Jan 5, 2015

bah I tried to revert back to driver 13.12 and I still don't see option. I do however see 2 cards when I right click at the bottom right tool bar I can change a lot of settings but don't see crossfirex =/

-Lone- · Jan 5, 2015

What's your CPU? It might have to do with the PCI-E lanes.

Johnny_R · Jan 5, 2015

using i7 4790

I think card is working because my fps has gone up a ton in dragon age inquisition im getting 55-60 with ultra settings + MSAAx2.

its bit choppy though even with high fps

-Lone- · Jan 5, 2015

I'm not sure, your CPU, GPU, and mobo all supports it. I don't think it is a power issue since everything is powered up and detected. So maybe some small part could be defective, like PCI-E lanes.

Johnny_R · Jan 5, 2015

tried reseating the card still no option =/

-Lone- · Jan 5, 2015

How long ago did you purchase them?

Johnny_R · Jan 5, 2015

most parts about 6 days ago and bought another card today.

I just tried to update bios for Asrock z97x fatality killer.

uninstall drivers reinstall didn't work ><

I do see 2 cards though bottom right options tool bar but not crossfire

-Lone- · Jan 5, 2015

That short ago? I think you should ditch the lower cards and get the 295x2, lol. The only issue you might have is the display ports with it, Omega driver works perfectly with it. It'll be faster, cooler, and no need to tweak with crossfire, it is already crossfire enabled.

Johnny_R · Jan 5, 2015

the shop I bought it from doesn't stock 295. msy

-Lone- · Jan 5, 2015

You bought it locally? Can't you refund the cards and get your money back and buy it from Amazon or something?

Johnny_R · Jan 5, 2015

yeah can try but is that really the only option =/

someone fixed it with this.

thoughts?

"I just got it working today. Steps I took:

Make sure EPI and TPI switches are set to Default (off) mode on the motherboard.

Make sure Both video cards are in "Quiet" BIOS Mode. (the switch towards the back of the card, can be changed later)

Make sure Both video card have 2 PCI-E power cables to each card (4 total). The cables I have have two connectors each, but they may not have been able to deliver the power needed with 1 cable.

Driver sweeper (safe mode) and install latest (non-beta) drivers with ONE CARD ONLY installed (this step may be unnecessary).

Driver sweeper (safe mode) and install latest drivers with BOTH CARDS.

After all of this, the CCC automatically turned on CrossfireX when taking me to the configuration page."

I wouldn't say it is the only option, but the 295x2 really is better from personal experience. 2 of your current cards in the size of 1, but you may have to upgrade your GPU if you're under 1000w. I have 2 of them and I can play my games 4k@ultra, like FC4 and BF4, very nice graphics if you wanna go up to 4k

-Lone- · Jan 5, 2015

Yeah, that's the same exact thread I found, lol.
