how to turn off ATI graphics card power managerment? - Page 3

post #21 of 23
From what I understood it just throttles your GPU high enough from the idle clock to watch youtube, hence why its always at 400mhz when viewing youtube clips, but once you uncheck it, it allows CCC to determine the amount of clock speed neeeded, so either idle or max. That's how I interpreted and it works for me without any problems as I couldn't game before with youtube on because it set my clock at 400mhz

You don't want to do this. This is your card running in Unified Video Decoder (UVD) mode. This mode allows hardware accelerated playback of video of h.264 and vc-1 content. It is completely normal for video cards to have specific clocks when playing back video content. Nvidia does the same thing iirc.

I also have a 5770 (running Cat. 10.12) and it plays back Flash, blu-rays, h.264 content well with no artifacts/green screens/etc.
