Hi tom's hardware, I've discovered that one of my GPUs is not working at all.
Bare with me while i describe the procedures I've tried to resolve this issue without success.
The card IS detected by catalyst center but it shows 0% activity at all times.
I've used all kinds of software like speedfan,gpu-z,furmark and HW to monitor the temperatures of both GPUs and even when I'm running fullscreen fullmark it only shows one GPU.
The temperature of the malfunctioning GPU is never above 45 Celsius, while the working one goes up to 90 with furmark (if I let it run a while).
The other weird thing is that furmark recognizes my second GPU when I turn off the crossfire option(disable) in Catalyst Center.
It doesn't recognize both GPUs with crossfire enabled, how weird is that!
Though even when it recognizes the second GPU, it still shows 0% activity and no change in temperature when running the stresstest.
Also, I get a score of 300 with a 8second fullscreen test with crossfire enabled but with only one GPU recognized by furmark.
I get a score of 160 with a 8 second fullscreen test with crossfire disabled but both GPUs recognized by furmark
Asking my brother who claims to know his stuff around computers he said to me that furmark and catalyst may show 0% activity but the card is still working.
Then my question is, if the card is working, why isn't the temperature of the suspicious card rising?
Another thing is that if I switch the "blue end" cable connecting the monitor with the GPU so that it will connect the monitor and the suspicious GPU, the screen stays black, as if it wouldn't recognize the GPU.
One more thing, when I start gpu-z I get a message that OpelCL is not working and I should reinstall the AMD APP SDK thing. Well, I've done that too and still getting that message.
My thoughts on this would be that the OpenCL isn't recognized on the malfunctioning card, cause OpenCL has to be working on one card cause the furmark test is a OpenCL test, isn't it.
Couple of things:
-Yes, I've double checked the cables.
-Yes, I've double checked the crossfire bridge
-Yes, I've reinstalled Catalyst Center several times, even going to older versions back and forth.
-Yes, the crossfire option is enabled in Catalyst Center
Ok, I hope I haven't forgotten about anything important. Let me know If more info is needed.
Oh my specs are:
gpu: crossfire 4850 radeon
processor: AMD Phenom II X4 965 Processor (4 GPUs) ~3.4 GHz
RAM: 4 GB DDR3
motherboard: ASRock M3A770DE
power supply: OCZ600MXSP (600W)
