How To Make Sure Crossfire Is Working?

Much thanks for the replies!

I did try to over clock my cpu, with no luck in the results. I don't think it's the cpu that's the problem, though. With both my 6100 and 8350, the slightest overclock results in instability, windows not booting, loss of areo mode and other random issues with windows not booting properly. I'm thinking my board just doesn't like overclocking, or I'm just doing it wrong. I'll try overclocking again, but may also get a new board and possibly windows 8.

Don't suppose you've a guide for setting up the fan curve in afterburner when using crossfire ? I want to find a happy medium between noise and Cooling on the top card scared of it getting too hot!

These are the settings you want. As for the profile itself well just experiment and see what works for you. It varies from card to card.

Made a little discovery yesterday while trying to figure out why half of my fully supported crossfire games were not using the second GPU.

That innocent little "Enable AMD CrossireX for applications that have no associated application profile" was the culprit. With that ticked I only get usage on one GPU for games like Diablo 3 that definitely have a profile. Crossfire worked on Crysis 3 though, so I'm not sure what the pattern is.

With that setting unticked I get the full-on sexy 100% utilisation across both cards, as I've come to know and love on my R9 290s.

Hmm now that I think about it the link is probably Tridef 3D. I only tested across 4 games, but the 2 that didn't work used Tridef.

That's an interesting discovery. I've had that ticked for a long time and have not noticed an issue. That said, i will now untick it just incase. :p

Where abouts is this setting ? I will have to check this :)
 
What happens when crossfire says it's working, but it's not? :(

I have the following config:

Asus Z97 Deluxe
Devil's Canyon i7 4790K 4Ghz
8gb RAM,
1200W BeQuiet PSU
2x Sapphire R9 290 Tri-X OC (tried both current CCC 14.4 and 14.7 RC installations), both in the first two PCIEX_16 slots, 1 & 2 on the mobo.

all pushing my existing 60Hz 24" 1080p monitor, over hdmi.

I get the CrossfireX logo in games that support it, but the performance (i.e. fps) is identical regardless of whether or not I use one or two cards, and I've tried both cards individually and both are working 100% on their own, but only one card works when both are in the system together.

I get a score of 13,984 in the firestrike benchmark in 3DMark and using the 'extreme' settings in the Heaven benchmark I get about 65fps and a score of 1649, but this is the same </> 1-2fps regardless of whether I use one or both GPU's and in games I'm getting around 40fps in arma 3, sniper elite 3, far cry 3 and crysis 3 with all settings maxxed out. also I just realised that everything i'm playing seems to be the 3rd installment! :)

I checked the settings mentioned on the first post of this thread and they're all correct, although they're identical Sapphire cards, not MSI cards, so I don't have the MSI afterburner app. i've just found a similar app for Sapphire cards, but not tried that yet, so not sure if that will affect it.

The two cards are detected and crossfire is enabled in CCC, so I'm not sure what the issue is. I've tried swapping power cables round on the cards, but it makes no difference and it's always the same card that is used.

does it matter which card I have the monitor connected to? I also have a 2nd monitor connected via DVI that I use to check performance (using OpenHardwareMonitor, task manager & CCC, but OHM shows what I'm experiencing, that only one card is active in games and I'm not sure what could be the problem and if it's a hardware limitation (monitor, or cable, motherboard issue maybe?) or if it's a software configuration problem.

Any help would be greatly appreciated. :)

How do you know performance doesn't change, are you using Vsync?
Click to expand...
No, vsync is off.

if i play a game with one card installed, it runs at exactly the same framerate as with two cards installed.

I've taken both cards out and tested them individually in the same system and performance never changes by more than one or two fps in any game or benchmark with either card or both cards in use, so whichever way I test it, i'm not getting any better performance.

if i have both cards installed, i get the CrossfireX logo in games that support it, but the performance is no different than with a single card and Open Hardware Monitor shows the 2nd card is running at idle, identical to as if i weren't playing a game at all.

when I run the heaven benchmark, it shows both cards in the total, but the performance is no different than when I run it with a single card, as you can see from the below results.

Show me the performance overlays as instructed in the guide please. Let's see what the gpu usage is going. Before you do that open up CCC and select restore factory defaults.
Double check crossfire is enabled in CCC too.

i'm at work atm, but i'll be home in the next hour or so and i'll do that, thanks a mill for all the help, i know i'll get there. :)

The two Heaven screenshots show you're running in Windowed mode. Don't forget Crossfire only works in Full Screen mode (except Mantle games).

ah, didn't know that, but I've tried it in fullscreen too and it's (the heaven benchmark) not any different, it's just that when you choose the "extreme" preset in Heaven, it changes to windowed mode at 1600x900 and locks out all other settings, i'll try it fullscreen again anyway to confirm but all the games i've played are definitely all in fullscreen, not windowed.

i''l get home and sort out the factory defaults and get the overlay working anyway and we can take it from there, thanks again.

i think Stu wins a cookie! :D

and here's FC3 running correctly with CrossfireX! :)

fc3_crossfire_fps.jpg


looks like FC3 had wandered into "borderless" mode from fullscreen somehow and as Stu says, it doesn't work in anything except fullscreen.

also finding that if i Alt+Tab to another window and then back again, it kills Crossfire entirely and goes back to a single card (and much lower fps).

so the big question is, who do i write the cheque out to? :D
 
Stu takes the credit for this one. :)

Now you've enabled the overlay though it will allow you to keep an eye on things and ensure performance and scaling is where it should be. Essential for every crossfire enthusiast. :cool:
 
when I read your guide initially, I hadn't realised that the MSI Afterburner app would still function even though I wasn't running MSI gfx cards, so I hadn't used it.

Anyway, as you say, now I have the overlay sorted out, I'll be able to keep a proper eye on it. I'd had fraps running previously, but it really doesn't give you enough info to be useful for anything except basic fps counting.

Still not got it working in far cry 3, but now i know what to look for and a little more on how to troubleshoot (and that pesky full screen thing!) i think I'll be okay, so thanks a million for all the help. :)

only thing i'm still kicking myself about is that i got one of the cards off amazon because it was a couple of quid cheaper, but they aren't doing the golden ticket thing so i missed out on 3 free games. still got 3 with a voucher for the other card though that i got off overclockers, so it's not all bad. :)
