Post by: CartmanSPC on May 09, 2013, 09:23:28 PM
Anyone run into this?

The GPU #, temp, and RPM lines are mixed up:

Sorry about the hyperlink to flickr. What do you use to embed the image?

That happens when you use intensity >15
The GPU load becomes very big and unstable behavior may occurred
Use thermal monitoring system for your OS

Seems to happen no matter what the intensity is set at. In the example it is set to 13.

Think it has something to do with --gpu-map
Investigating :)

Think I figured it out.

Adding this setting fixed it: --gpu-map 0:1,1:0

I guessed as I did not know how to find the ADL number. Anyone know how to find the ADL number without having to install the AMD Display Library?

You must install the SDK libraries anyway or else it wont work. I had broken my head to find out. If any one has other idea just say it.

Ok, it's all in the GPU-README.
