Dear all, I apologize for asking you to help me troubleshoot my computer, but I am currently very frustrated. I am no stranger to OCing and hardware; in fact I am pretty active for at least 3 years now. However, I encountered a problem that I cannot solved by myself.
Problem: I cannot crossfire anymore.
I have 2 6970 on cfx through ccc. Last month in the overdrive tab, the second 6970 card start to not function. Example, I set both GPU's fan speed at 60%, after a few minute my second GPU sudden goes back to stock fan speed. When I go to CCC->Overdrive->2nd GPU, everything is at 0%, I am unable to check anything. When I look at my open case computer the GPU is running.
What I have done (and didn't work apparently.)
1) uninstall and re-install several versions of CCC -> failed
2) test my PCIE slot to see whether is it my motherboard's fault. Nope Mobo is fine and the PCIE slot is functioning -> failed
3) Ok, so maybe is just fan speed having problem. Run a game, go to GPU-Z and see if my second GPU is functioning. Results, 2nd GPU is functioning, the clockspeed, the fan speed and etc... is being displayed. HOWEVER, the GPU load is always at 0% no matter how I stretch it. -> Failed
4) Use a different crossfire bridge. Same results -> Failed
5) Switch the GPUs. Same results ->failed
So at this point, I am pretty sure it's the software issue. The 2nd GPU seem to be functioning, but it is unable to be controlled through CCC after roughly 2 minutes.
6) So I downloaded RadeonPro. I used radeonpro to adjust both GPU's fan speed to 60%. It worked, the second GPU's fan speed didn't return to idle or become uncontrollable like in CCC. HOWEVER, when I use radeonpro to run a game and use GPU-Z to see whether it is using the second GPU. The load is still zero.
The only thing I didn't do, or I don't know how to do is to "enable" crossfire in readonpro. I searched every tab and I can't find it. In the overdrive radeonpro did read 2 gpu though. I am assuming its doing CFX automatically.
My troubleshooting ends here as I cannot come up with any hypothesis of any error. So please help me.
Your time and help will greatly be appreciated.
