Extremely Annoying Crossfire Issues / Woes

Hey all,

I'm having some VERY frustrating :mad: problems with my Crossfire setup and was wondering if you could help me solve them.

First of, Resident Evil 5, running the bench with Crossfire enabled or disabled in CCC seems to make hardly any difference to FPS what so ever, I've also noticed that I'm not getting over 60FPS 100% of the time in Crysis on all very high with no AA which I find ridiculous (at 1920x1200). I've checked usage/clocks and both go up when the game is playing but it doesn't actually seem to increase the performance!

Another thing: CCC and MSI Afterburner really don't seem to like each other, I'm using MSI to overclock to 900/1375 but sometimes it just defaults back to 800/1250 and no amount of fiddling with MSI gets the clocks back up?! Similarly with fan control in CCC and my MSI fan profile; CCC always reverts back to 'control fan speed manually' yet I never tick it and sometimes the fans just jump to 50% when CCC loads despite MSI's fan profile still running.

Power control settings don't seem to stay for very long, I set it to 20% but every now and again I'll go in to CCC to find that it's been reset back to 0.

Lastly, in another thread recently I asked about switching which is the main GPU but I'm not sure whether or not my motherboard can do it? There's an option to change the initial display port but this does not seem to switch around the GPU number assignment. All that the option has done is to disable any output display until windows loads and if I plug the monitors in the other card I only get a display up until when windows loads

Just about had it if I'm honest, my setup just does not seem to want to work and that extra 200 quid feels like a total waste of money.
 
I'm having the same problem, have twin 5870s and in Black Ops I have to disable crossfire else I get even worse framerates. In Crysis 2 on max I should be getting more than 40-50 with xfire but I dont. I'm frustrated and tbh regret even bothering with xfire :(

Download the 'Extra ToolBox v1.00' from here - last link in 1st post :

In the Directx SDK folder, run the DxCaps Viewer and check to make sure that it shows your cards properly - i.e it lists them as 6950's and not something else.

Does the Resi 5 benchmark screen show the cards properly as 6950 once it's finished ?

Do you have the Catalyst Application Profiles installed ?

If you do, then download RadeonPro & try the Resi 5 crossfire profile to see if it helps ?

Make sure you're running Crysis in Dx9 mode ( just use a decent custom config - http://forums.overclockers.co.uk/showthread.php?t=18235428 ) as dx10 / 64bit adds nothing really other than lower fps.

Plus, Crysis 1 has always suffered from poor multi-gpu scaling. You get about 50% extra fps over a single card if you're lucky.

Another thing: CCC and MSI Afterburner really don't seem to like each other, I'm using MSI to overclock to 900/1375 but sometimes it just defaults back to 800/1250 and no amount of fiddling with MSI gets the clocks back up?!

Have you got Overdrive unlocked in CCC ? If you do then deactivate it as it caused me issues with Afterburner when I was running 5770 crossfire.

Although tbh I had a few issues with Afterburner and crossfire anyway, in that at times it would only apply an overclock to 1 card even though the option to 'mirror settings between similar cards', or whatever it was called, was enabled in AB's settings.

I'm running 5970 Quadfire & Black Ops runs smooth as silk.

As for crysis2 the blame is with the game as they changed & broke the initial SLI/xfire support when they released the game & i don't worry or regret having xfire because a couple of games now & then having issues on release because of the developers.
Its not like they are the only 2 games that you have.

Want something special like a Bugatti then sometimes you have to join the year long waiting list.
But are you then going to regret buying one because you cant use all that power all the time because not all the roads are straight.

Nothing is perfect, take the rough with the smooth because Multi GPU works a hell of allot more often than it don't.

Its not just those two games though, things like Shift 2 don't work properly with it and its just more hassle than its worth. Single gpu for me from now on!

And MoodyB yes I have tried all the fixes, doesnt make any difference :( Using about 30% of each gpu which is a complete disgrace

So that's 3 games that you own.
Its your choice but i don't have that issue as i don't tend to play games at launch as they are too often full of bugs anyway.

I have a huge back log of games that i will be playing in full multi GPU glory because i have patiences & its cheaper to as i waited for the price to drop so its a Win Win for me on both fronts.

The Shift 2 crossfire issue is a developer problem. They have admitted this and are fixing it in the upcoming patch, which is due in a few weeks I think.

You're still not going to get twice the fps of a single card, but that is down to how their renderer works & not a fault of ATi / NV :

I having that problem ati 5970+5870 triplefire set up when i run same time GPU-Z auto fan work correctly
 
I feel your pain..I added another 5870 to my system in Crossfire as I run a 27" monitor at 2560x1440 only to find out there were problems with some games, it caused real problems in my main game at the time, LOTRO. There was major stuttering and slower FPS most of the time than the single card. I should have done more research as the problems were already well documented on the forums :(

In the end I bit the bullet and replaced the the Crossfired 5870's with a GTX580 and TBH it certainly doesn't seem any slower and fixed all the stuttering problems.

Moving away from a single high powered card was an expensive mistake to make and I'll be giving multi-card configs a wide berth for the foreseeable future.
 
I don't have the answer to your problems but Resident Evil 5 scales pretty well in Crossfire.

I've just done a quick test with my two 6850's.

2560x1600, DX10, no AA and the fixed benchmark:

Single card 68.0fps

Crossfire 129.2fps

A 90% increase with the second card. Not too shabby.

Yep.

You'll need to be running in dx9 for the final level anyway, as it crashes when using dx10 iirc.

Hmm, it makes quite a difference in performance and allows me to run 4xAA at 1920x1200.

Is DX10 not optimized? it seems poor on it's own even without AA.
