kn6600 Posted December 28, 2017 Share Posted December 28, 2017 Hi, I managed to fix fun issue on Vega card with modification of Info.plist from AMD10000Controller.kext. Change value for "PP_PhmUseDummyBackEnd" from 0 to 1 ( to enable Dummy Backend). With this I don't have flashing power leds and fans are normal. - edit Fans are ok but youtube is hanging on 1440p , please check. 4 Link to comment Share on other sites More sharing options...
mrmggo Posted December 29, 2017 Share Posted December 29, 2017 (edited) This method works well. My vega 64 does not flash, the fan is normal. Thank you! Do not know whether to use clover to achieve change safari only supports 1440p youtube 4K Please use Chrome Fix this file, GPU up to 1Ghz Geekbench Score 136XXX This seems regrettable No fix, GPU up to 1.765Ghz Geekbench Score 209XXX （I can not upload pictures） Edited December 29, 2017 by mrmggo 1 Link to comment Share on other sites More sharing options...

Wonder if another value could be used or if following this edit to source and looking in the RadeonxController to adjust values manually? Here is a pic of the fix using xCode.

Arkanis Posted December 30, 2017 Share Posted December 30, 2017 Interesting, will make some test later on my side (Vega 64 here). Link to comment Share on other sites More sharing options...

Screen Shot 2017-12-29 at 8.36.54 AM.png Bad news，if you use amd graphics driver from bootcamp driver in Windows，the fan also in high speed like it in macOS 10.13.2 It seems that the apple is doing this on purpose.

UcaUca Posted January 24, 2018 Share Posted January 24, 2018 I found a quite interesting way of enabling the Vega frontiers fan control under 10.13.3. Apparently, if a opencl or metal thread is started, the fan noise lowers immediately. The thread doesn’t have to do something actively, it’s enough that it is started. While watching a YouTube video I noticed the fan slowing down to complete silence. This works also if you open a mp4 video in QuickTime and leave it paused in the background. I automated this by writing this into a script: open /path/to/yourvideo.mp4 --hide I saved the file as silencing.command and added it to the startup section of the system settings under “user”. This way the video is started automatically at boot and put to background. The video won’t playback automatically so no disturbing noise or performance draw. In order to make the terminal window close automatically after it has been opened, open terminal settings and under the window section you can tell terminal to close window upon successful exit. Enjoy. Link to comment Share on other sites More sharing options...

UcaUca Posted January 25, 2018 Share Posted January 25, 2018 This GPU temperature will be abnormal So why does it behave that way than? What if I’m used to have videos running in background while working ? Is that a forbidden scenario? Link to comment Share on other sites More sharing options...
