Hi there guys and girls, I'd just like to ask all of you wonderfal people for alittle bit of help. So i've got my second R9 290 Tri-X finaly i put it into my PC the fans are working fine. But then i was looking on the AMD Catalyst Control Center at how to enable the crossfire because these cards don't need the crossfire briged. I haven't found out how to enable it can someone please help me?

Crossfire is enabled by default on the R9 290 and 290X. You don't need to enable it on any sort of menus and such.

Quote:
Once we had the hardware installed we simply installed the driver, and rebooted. Upon reboot CrossFire was enabled by default. All we had to do was create our Eyefinity 3x1 configuration, which after a few clicks was done. We did not have to reboot after configuring Eyefinity, we were able to game immediately. We had no issues running any games at Eyefinity resolutions, or 4K resolution.

To the user, enabling and disabling CrossFire is exactly the same as it was before. You can go into Catalyst Control Center and disable CrossFire, or enable it with a radio button. A reboot is not required. The software side is exactly the same. Though it is odd looking over and seeing no bridge atop the video cards, CrossFire worked perfectly with no issues, and we saw incredible CrossFire scaling as we will show later in this evaluation.

What game(s) are you referring to? Do you know if your motherboard supports crossfire? It's not as uncommon as you think but many manufacturers don't offer proper crossfire or SLI support on some of their boards (a good example of that being MSI's GD-65 not supporting tri-SLI but it does support tri-Crossfire).

Try plugging them into the same slot type (x8 and x8 instead of x16 and x8). Sometimes that causes issues as well.

I've got a Z97-K motherboard and i'm referring to games like Minecraft,Battlefild,Left 4 Dead and other games. And i'm running a display off this second grapics card so it must support it..

Oh you're not supposed to run a display off of the second GPU.

Quote:
All of the displays simply need to be plugged into one video card, you don't have to split these up between the two video cards like NVIDIA's Surround.


from the same review posted earlier

I'm guessing you have to plug them all into one card is because they're communicating over the PCI-E lanes instead of a bridge which means if you plug your monitors into separate GPUs it will treat them like two different discrete cards instead of a crossfire configuration.

Yes - just plug your monitors into one GPU and then you should enable crossfire mode.

Ok so i've pluged them into 1 GPU and i'm still getting the same FPS.

Do you have vsync on? That will cap the frame rate to the maxiumum refresh rate of your monitor at its native resolution (most monitors are at 60Hz) Honestly I don't see how you could get lower than 60fps on any of the titles you listed anyways.

Go into CCC and make sure Crossfire is enabled under either the gaming or performance tabs. When I first put in another 290x I had checked to see if cf was enabled in CCC and although I thought it was, when I played a game I got a mediocre FPS, so I exited and checked again and it was actually off. Also, make a crossfire profile for whatever game in the 3D application settings under the gaming tab in CCC and see if either optimize 1x1 or afr gives you better frames while having frame pacing enabled.

Overclocking these things, if you want consistent and fixed clocks and are using afterburner, make sure that after having adjusted the settings for both cards in ab that you increase the power limit to +50 (or whatever you increased your limit to in ab) for both in the overdrive settings under the performance tab in CCC. Make sure that you also disable ULPS in ab's settings as well.

Are you running these games in windowed mode? Or alt-tabbing out of the game during gameplay?

That's my problem. There isn't any "Enable crossfireX" in my CCC. Please help :(

Is your second card being detected under display adapters in your device manager? Also, I'm using CCC 14.7 beta, so the enable crossfire option might be an added function, dunno.

Uninstall CCC and install the 14.7 beta then, see if that makes a difference. If your second card is being detected, the option should be there.

A Thermaltake SP-750M and a Corsair CX500M. Not having the option to enable crossfire should have nothing to do with the rated wattage of your PSU though.

Hmm, if it is the beta that was released in August, I'm not sure then. On 8.1 Pro and a Z97 Extreme 3, putting in the other card was pretty much plug and play for me other than having to enable it. Your motherboard should be capable of cf over XDMA. The only other thing I can think of is uninstalling the drivers (including CCC) for your cards, shutting down, unplugging the PCIE cables from the cards and momentarily removing one from the PCIE slots while completely removing the other, reinstall just the one card and download the drivers from AMD's website (August catalyst beta), shutting down, then install your other card to PCIE slot. The purpose of the above is to see if a fresh start makes a difference.

Other than that, I don't know, if that doesn't work sorry I couldn't be of help. Your second card is at least being detected, but kinda hard to narrow down the exact issue.
