Please help me

Unfortunately Leonardo27 I have the same problem as well. Apple released new imacs which support 8th and 9th gen intel cpus. Also as Im reading there will be better native support for amd gpus. The update in my country (Greece) isn't available yet. Final we have to wait for the next clover which will provide the new smbios 19.2 and 19.3 for our cpus. Soon we will know...

Updated to 10.14.4 successfully... random freezes are still present. Fighting to find a solution...
Something to mention from the beginning of building this system is that I never had a freeze while screensaver is on. Without the screensaver and while in idle mode freezes are often.

@shuhung is still your system stable with new update 10.14.4 and smbios imcapro1.1 ?

Yes, very stable.

Try disable IGPU from BIOS, use SMBIOS iMacPro1,1 and dummy141 kext to enable RX4XX/5XX IOGVA support, place it into Clover/kexts/Other folder.

I did and share results soon, thank Shuhung!
HEVC support works, jpg files open, geekbench and bruce X give same results as before.
Do I have to disable also "Load Vbios", "inject intel", igplatform-id" and set "intelgfx to 0x0" ?

Just disable IGPU from BIOS, no relevant to IGPU injection on Clover config.plist.

So except that I disabled igpu in bios, everything else stays as it is. So I just had a freeze again but this time a little different than before (random freezes were instant). I was working in fcpx and the software became unresponsive. After half a minute and while trying to force quit the system came completely unresponsive. I will further test also and share the results.
Thanks Shuhung for your help!

Ioreg seems to be normal.

Recently, no fix for H264 green artifacts issue yet, export as HEVC is recommended, basically AMD HEVC rendering performance same as H264 rendering.

On 10.14.5 beta 1, new IOGVAH264Encode property is added to AMDRadeonX4000, seems to be used for fix H264 issue, RX4XX/5XX IOGVA native supported but unfortunately entire AMD IOGVA support is broken on this beta, waiting for next beta release.
