Radeon VII in Mojave and Catalina


10 posts in this topic

Recommended Posts

I just wanted to report I have my Radeon VII working well under Mojave (10.14.5) and Catalina (beta 4). They both kernel panic on the tail end of shutdown resulting in a reboot rather than clean shutdown. The panic is not a cause of any problems after rebooting, though. Catalina's drivers are way more stable than the ones in Mojave. I sometimes get VRAM reading errors on boot under Mojave which I do not get on Catalina. I am using lilu and whatevergreen. I haven't needed to do anything else to make my card work.


As far as I can tell the features I use seem to be working properly. I drive 2 dell 1440p monitors @ 144hz. The video is stable and there is no weird artifacting. The games I play run great at roughly 25% better FPS than my Vega64 would do. I mainly play World of Warcraft. I don't seem to have any sort of hardware encoding for streaming to services like Twitch or Mixer. I also didn't with my VEGA64 so I didn't really expect anything new there. HDMI audio works fine, I plug my speaker set into the headphone jack on my monitor for proper audio. I haven't tested HDMI but the 3 display port ports work fine. I run my 2 monitors as an extended desktop and they work well. 


If there are any benchmarks anyone would like to see just reply and I'll run them. I'd kind of like to see a comparison of other Radeon VII owners cards to see if there are any configuration changes we can make to tweak them a bit.

Hi @slave-zeo, you can find some testing stuff here :



more generic testing here:



Here are a couple of Geekbench OpelCL numbers. the first is Mojave and the second is Catalina.








It looks like Catalina is a bit faster. I guess the drivers are being optimized a little.

you did not install the memory modules correctly - they work in a single channel, not in a dual channel




Why did you buy a motherboard on the Intel Z390 chipset? NVRAM does not work there and there are many other problems, unlike Intel Z370

Well I'll be danged. You are correct. I ended up picking up 2 more RAM modules for a total of 64GB so all slots are filled now. I should have checked the mobo manual first. Thanks for taking the time to explain and posting the manual page.


From what I read my CPU has power draw problems on Z370 motherboards. So I went with the recommended Z390. It is running stable thus far so I have no real complaints.


I purchased this setup for use mainly in Linux (Fedora) but I've always a sucker for macOS.

I do not, but if I knew how to get them I would.

Hey man! Is your system stable?

I have Radeon VII and sometimes my system freeze and on boot I have that kernel panic:
