In Topic: Vega Frontier Edition on High Sierra

Getting the following error when I enable 2 Vega cards, and then black screen.

kernel[0]: X86PlatformPlugin:: cgRegisterCallbackHandler - gpu internal PLimit notification already registered

Anyone having similar issues?

Update. RX Vega 64 working OOB on Beta 8. I'm trying to get both the FE and RX cards working at the same time, but no luck.

Outstanding!  Thanks surfinchina!!


Any luck with 3 or 4 monitor configurations?  My Vega system has trouble beyond 1 DisplayPort and 1 HDMI (2 monitors).


I have all 3 DP working with 5k displays. See above.

Thanks jnolla!  I bought the Vega Frontier Edition and it works in High Sierra OOTB, no helper, no iGPU just like you said!  


A question for you.  For me I also noticed that AirPlay also works OOTB.  Did you notice that too?  Is that because of Vega or some other reason?




Congratulations! I'm not really sure if it's Vega related or not, but AirPlay works OOTB for me as well.

RX Vega is coming at lower price points! This will be a no brainer :)


In Topic: AMD Polaris IDs on Sierra / High Sierra

It is hard to get dual AMD cards to work, my Haswell pentium supports 2 RX 480s using IGPU (Framebuffer only no acceleration) the Polaris cards work well in some open CL apps, a slight reduction in open GL performance but still working.

However, if using Braodwell, Skylake or KabyLake systems it is very hard if not impossible to get dual AMD Polaris cards to work. There is one person I know of who has disabled most of his IGPU drivers on a Skylake and has partial dual card support but like my setup with the Haswell pentium.

If you really want to get RX 480 working you may need to get a cheap Gt210 or other Nvidia card as helper or simulated iGPU. $30 US for a cheap helper card, I have found the Nvidia cards work great for this purpose and usually allow full sleep wake function for the RX.

I think you will have better luck running dual Vegas than a combo of Polaris and Vega. It may work with your Skylake or Kaby setup if you disable the IGPU drivers.


Keeping my hopes up. I can have them boot, but no acceleration if I fake a random ID. It might be something missing in Clover.
