A friend of mine has a system and I will test it later. The lack of luck, I sold my old GPU and shipped right before finding out this problem, otherwise I would have tested if it was related to the MoBo. Bad timing.
I was using it normally, shut it down and then, the next time I tried to turn the computer on, it wasn't posting video through the RX 480. I was able to get video through the iGPU but neither the MoBo or the system recognises the RX 480.
I tried cleaning the contacts, nothing.
The RX 480 is...
So I've tested it using the IGPU as the display, it forced me to use Intel Inject, otherwise it wouldn't work and only 0x0166007 worked. But it behaves the same way as when I use PEG as first choice. Interesting enough, if I use Inject ATI, it behaves as when I turn off IGPU on BIOS but the...
I will try it, if that solves everything, it would be awesome. It's just that from what I've read, most pple use the dedicated GPU as a primary display.
What I found out is that with both iGPU+GPU I get H.264 acceleration but no H.265, but if I only use GPU and no iGPU, it renders H.265 much faster with acceleration BUT, it freezes or fail when I try to render H.264.
In my BIOS it's iGPU 64MB and PEG as a primary display. On iStat it shows both GPU just like in Clover bootloader.
Full support? Is there something separately that I have to do just for that?
What I found out is that with iGPU+RX480 I can render H.264 but no hardware acceleration for H.265, if I turn off iGPU and only use the RX480, I can render H.265 but it will freeze if I try H.264. In theory with iGPU+RX480 I should be able to render both, but that's not what happens.
Oh, now I see...
12= ForceCompatibleRenderer + AddExecutableWhitelist
28= ForceCompatibleRenderer + AddExecutableWhitelist +DisabledUnused16
I was using just 4, since that's what was recommended for some guide I tried.
What's -rad4200?
Do I have to play around with the values? I got it to render with the iMac 19,1 but it's pretty slow, so I wonder what can I do to make it render properly. Thanks!
This?
SMB_BIOS_VERSION "IM191.88Z.0058.B00.1705091711"
SMB_PRODUCT_NAME "iMac19,1"
SMB_BOARD_PRODUCT "Mac-CF21D135A7D34AA6"
I just don't know where to put Board Product.
Board Type, Board-ID, Board Manufacturer, Board Version or Board Serial Number?
I tried 32MB, 64MB, 128MB, 512MB, 1024MB.
Same result, but for now, I will let it be at 64MB. But does using more than 64MB help with performance?
Thanks!
I'm also having issues with H.264 and VERY SLOW H.265 exports. I was able to make it export once but it was a bit slow, so I tried something else, it didn't export anymore, I tried the same previous config and it never exported again.
10.13.6
GA-Z77-DS3H - 3570K Ivy Bridge - HD4000 - RX 480...
Does anything necessary to RX 480 to work? Doesn't 10.13.6 have native support for RX 470/480 as well as RX 570/580?
Mine is working without RadeonDeInit, I decided to put Lilu and Whatevergreen in the kext folder just in case. Init Display on BIOS set to auto as well as integrated graphics...
Thank you, in the end I gave up and bought a used RX 480 for just a bit more, even solved power consumption issue. Although I'm having problems rendering H.264 and H.265.
