Welcome to AMD OS X

Why not register now to gain full access.

I using external m-audio usb audio card, i made some tests:

youtube 1080 ----ok
mp4 movie 1080 with vlc & quicktime .......ok
Davinci resolve 1080p .........ok

How many delay? are you overclocking? can you test with woodoo or external usb card?


OC to 4.0 ghz, mem to 3200. using internal Realtek 1120. applealc I do nothing with no reset or inject, just boot-flag alcid=device id.
I can test with my usb DAC if needed but sound is perfect on pc.
only use external usb day for DSD and hi-rez recordings but it works fine.
trimmed down kext. put 15h patches into config.
getting 128k OpenCL , 42k on cpu both increases.
1080p on everything
youtube ok
mp4 and mkv on vlc, mp4 QuickTime ok
not a gamer
All seems to be working but need to test more and check logs.
I just don't like that 15h/16h works better then the one for 17h.
No word from Shaneee he said he was looking into. waiting on him he is admin..
Initially we thought it was the TSC that was at fault. TSC was reporting 500MHz faster using the 15h_16h patches but that doesn't seem to be the case. Myself, Algrey and XLNC are looking at it.

Wonderful guys !
You are awesome ! ;)
15h_16h patches seems to be the best for Zen CPU on Mojave 10.14.5/6, not only OpenGL and OpenCL performance are better but also easier for CPU tweaking, probably due to CPU bus frequency capable running at asynchronous mode.

Outstanding CPU performance, CPU frequency @3500MHz (BIOS and Clover settings optimised, 15h_16h) performance much better than CPU @3600MHz (17h), may even over come CPU @3800MHz.

Hello all
i am new to the forum and i see so many of you have your AMD systems running i was hoping for some help on mine.
i have an Gigabyte GA370 Gaming board -3 an AMD Ryzen7 1800x CPU, Viper memory 32 gigs running at 3200 and a Scandisk 500gig sdd drive and a AMD radeon XFX RX 580 video card with 8 gigs of memory. i am using the 17h for Ryzen
so here is the issue, i can not install Mojave 10.14.1 as it gets stuck with the switch to XPC or Bootstrap() message and then i get a kernel panic that is unreadable. i was able to install Mojave 10.14.1 using my AMD RX 550 card but the video is just generic and it flickers. now that i installed it with the 550 and i switch to the XFX 580 Mojave never loads it starts loading but never gets to the apple screen it just reboots. any help would be so awsome.
