My rig is working great driving a single display from Vega 64 via DisplayPort, but I'm having a devil of a time getting a TV monitor working via HDMI on the same card.
My TV lights up an input icon when I plug it to the Vega (see attached--notice the next port w/ nothing plugged in is grayed out). So I know some electrons are flowing (maybe EDID?), but it never gets a signal. I've tried several HDMI 2.0 cables.
I'm running a vanilla install of 10.14.6, as iMac19,1, with just Lilu (1.3.8) + Whatevergreen (1.3.1). System recognizes the Vega and seems to be correctly using the UHD630 headlessly. I just can't get HDMI out of the dGPU...
I've tried the "-raddvi" and "agdpmod=vit9696" boot args, no dice. I've tried the kext patch workaround for disabling board verification, also no go (not surprising as I think that method is now obsolete for my setup).
I hit the same wall running 10.14.2 as iMac18,3 with a different platform-id before updating.
Here's my whole EFI.
Any assistance at all is hugely appreciated!! Thanks y'all.
Hi guys, sorry for my English in the first place,
I have a Vega 64 with an amd ryzen cpu on Mojave 10.14.5 (yeah no native power management cpu/gpu possible with my config) and I have sometimes really bad performance with my gpu.
Not an expert but I think that the problem lies in a bad power management and/or control of the p states. With a benchmark like LuxMark I have a score around 300k, 100% gpu utilization and max frequencies in both memory and core (Im checking with HWmonitorsSMC2) but with others like geekbench my clock core remains around 100 max 500 with a score of 35k (Unigine valley and heaven can't maximize the frequency and utilization too). It seems that somehow the gpu can't adjust the frequency or the system can't ask the right amount of power/frequency to the gpu. The only scenario where it works as expected is under really heavy tasks (like I said LuxMark or partially Multiple Cubes/ Iron Fix Boxing Kings in OpenGL Extensions Viewer). Is there anything I can try? Like a manual adjustment of threshold or p states etc.
can somebody walkthrough with the mojave installation guide?
i have a mac high sierra 13.6 version on my macbook pro and want to install mojave on my desktop
