HD5850 CF Problem

post #1 of 6
Thread Starter 
Hi

Got me one more HD 5850 which I bought from my friend.
Have installed it without problems, bridge is on, however, the first time I started the computer "AMD VISION Control Center" announced that it did not support it / them the card I played with.
Installed new drivers and the CFX profile.

Now to the problem
MSI Afterburner show that one card (GPU1) always lies on the 150MHz clock speed. (GPU-Z shows it to)
Can't overclock one card from AMD GPU Clock Tool. (GPU1)
When I play one card just idles (GPU1) and remains at the same temp (35c) constant.

However, I noticed that I got a performance boost, ran BC2 maxed without any problems.
If I tried it with just one card I would have been at 30fps in fights. Now it's 60 in the fights and 90 just running around.

The cards are exactly the same model.
Can not find anything about Crossfire AMD VISION Control Center.
The Crossfire X tab isn't there for me, all there is is "Performance"

Have switched slots and tested another 5850 that my friend used with his but no go.

Help please

I had to completely uninstall the drivers from both add/remove programs and uninstall the display driver from the device manager. You can also download driver sweeper and have that help remove any extra stuff after you delete it. Then install the newest driver and CAP. If you cant figure it out, you can always reinstall windows. Having different brands does not matter. What motherboard are you using?

Yea did the uninstall program and device manager, going to try now again with driver sweeper.

Why is my CCC called AMD VISION Control Center?

Edit: Darn..
Attention - Guru3D Driver Sweeper has been discontinued as such you will not find any download links here any longer.

Are you using this driver?

I am not sure, I havent had an AMD card in a few months but I remember it always being called Catalyst Control Center. Also, with that you dont need MSI Afterburner for overclocking, you can do it in the Control center. I just used it for monitoring and overvolting. When I had my 5850s in CF, I could get the core clocks to 900 with no voltage tweaks. I miss them, best cards I ever had.

Yup thats the ones I'm using.

I only run Afterburner for the On Screen Display, have never been able to clock much in Control Center, 775 is max atm.
So have always used AMD GPU Clock Tool for that, 900 safe here to but only with one card atm =/

Fixed it.

I noticed that GPU1 was running @ PCI-E x2 so i cleaned out all drivers and **** yet again and put in another 5850. And booted with only 1 screen.(got two and had been using them on the same card, gpu1)

Installed Drivers and not it's working, running successfully CrossfireX

So if you got the same problem, clean everything for your upgrade, and boot only with only screen on your graphicscard.
Else it's something wrong with the card.

As I'm going on LAN tomorrow I don't have to time to check if it's only the GPU or 2screens problem.
