All works. Fantastic. There is a way to control Radeon Vega fan? 

 

The Vega fan speed is probably linked to the iMac Pro which has a Vega card with Heat Pipes and no fan just 2 system fans so it seems to run like a CPU or System fan.    About 30 seconds after boot it speeds up even at idle.    My temps for RX Vega 64 are 24C at idle and reach 84C during Luxmark Ball benchmark which is a 2+ minute heavy load bench.

 

The good news its that the GPU isn't overheating it stays cool its just overworking the fan, I feel cool air coming out of my IO port when at idle and it warms during heavy use but quickly cools down again at idle.     When Apple realeses the EGPU variants for Vega maybe they will provide new or different fan controls for the card.

I also tested the Radeon Pro Vega 56's driver in Windows 10 Fall Creators Update from bootcamp driver, when I using this driver, the GPU fan speed as high as it in macOS 10.13.2。

For those who are waiting for solution with Radeon VII and Radeon 5700 read please the topic and use for tests new kext RadeonPCI5-v2.

The purpose of tests is to find registers which change when GPU temperature increased.

See the whole thread about previous tests.

Do we need to have clover for test? I use OC and I am getting:

pavle@iMac ~ % RadeonDump1 -n 6b0,c0300e0c

zsh: bad CPU type in executable: RadeonDump1

Thanks, this is the result:

pavle@iMac ~ % RadeonDump -n 6b0,c0300e0c            

Found a device of class RadeonPCI: IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/RadeonPCI

it matched on name "display"

Assertion failed: (KERN_SUCCESS == kr), function main, file /Users/sergey/Downloads/RadeonPCI/RadeonDump.c, line 239.

      Hello everyone, i just want to ask something. why is it that my radeon hd 7770 graphic card was detected as "Latte" gpu instead of verde when using radeon_bios_decode? is the card actually a Latte graphic card but someone flashed it so they can sold to me as radeon hd 7770? or is it actually a real radeon hd 7770 but the tool falsely detected it as latte cpu?

      Radeon RX 580 8 GB graphics card on macOS High Sierra (as of 10.13.6), Mojave and Catalina on the P55-USB3 board: excellent performance with acceleration (Metal) OOB, no need for drivers (kexts), with 3 drawbacks, one has to do with the boot of the operating system (a solution is proposed), another with the number of rear connectors enabled (a solution is proposed) and another that only affects to one phase of the Mojave or Catalina installation (without clear solution for now).

      I have placed the XFX AMD Radeon RX-580 P8DFD6 8GB Triple X Edition GDDR5, 256BIT, DVI + HDMI + 3DP graphics card on a 10 year old motherboard (Gigabyte P55-USB3) in order to update the hackintosh to 10.14 Mojave and 10.15 Catalina because the card that I have used in past years, Nvidia Geforce GTX 750 1GB, has stopped working after 10.13.6 High Sierra since this was the last version for which Nvidia published the alternate web drivers that were necessary for the card to work well with graphic acceleration.

      The new RX 580 card needs considerably more space than the old one although it fits perfectly in an ATX case, and requires an additional power connector. It has 2 big fans that most of the time are stopped, at least in my case. In macOS it works perfectly, even with Metal acceleration, without additional drivers and without extra settings in Clover. But it has drawbacks that I comment below.

      Alterations during startup

      During the boot of the operating system, when the screen goes from the basic driver to the AMD driver, 2 artifacts appear randomly, they are very short in duration (from one to a few seconds):
      Very short flashing white screen that may or may not be accompanied by purple lines The fans runs for a few seconds (the noise is clearly audible). This behavior is solved with the installation of 2 kexts, Lilu and WhateverGreen. Lilu is an extension created by acidantheraand vit9696 among others whose function is to help to patch kexts, processes and libraries during macOS boot. It is accompanied by specific plugins for the task required, for example WhateverGreen that injects necessary patches for certain AMD, Intel and Nvidia graphics cards. It is mandatory to have both extensions together, one of them separately does not correct the problem.
      I have installed Lilu 1.4.4 and WhateverGreen 1.3.9 in the EFI/CLOVER/kexts/Other folder of the EFI partition and artifacts have disappeared. Remember that these 2 extensions are not necessary for the card to work properly, if you tolerate those very brief distortions of the screen or the noise of the fans running for a few seconds, you can live without Lilu and WhateverGreen.

      Note: authors recommend that when using Lilu and WhateverGreen with Radeon cards, NO graphic settings have to be added to Clover (Inject ATI, etc.).

      Note: these alterations, especially the brief white screen and less frequently purple lines and fan noise, are also seen in Windows and some real Macs with the same card.

      Alteration during macOS installation

      Boot from USB > Clover menu > Install macOS from Install macOS Catalina > screen works fine
      Boot from USB > Clover menu > Install macOS from MacintoshHD > black screen
      Booting from USB > Clover menu > Boot macOS from MacintoshHD > screen works fine.

      In the first and third stages, screen works fine. In the second stage the screen goes black although the installation continues. The user has nothing to do at this moment so you can leave the PC working until the Clover menu is shown again, the screen is recovered, the initial account options can be configured and you can enter into the newly installed system with correct resolution and acceleration.
      This behavior is not corrected even by placing Lilu and WhateverGreen into the USB device. At least in my case I have not found a solution for it. Yo can install macOS perfectly with that drawback of not seeing how it progresses during the second phase of the installation.

      Only 2 connectors of the 5 available work

      This card has 3 Display Port (DP) ports, 1 HDMI port and 1 DVI port. In my case, only 2 DP work, those that are further from the HDMI connector. It is enough if you use a single monitor or 2 monitors that can be connected by DP. But if you want to have 3 or more connected devices or some of them only have HDMI, it is necessary to enable the 5 connectors or at least 4 of them since the DVI is obsolete and does not allow resolutions as high as DP and HDMI.
      User foxbox has proposed a solution in a thread titled [Solved] Sapphire RX 580 Nitro + SE | black screen on HDMI and DVI. Must inject from Clover a modification to the Orinoco framebuffer (which is used in the RX 580 card) so that the 5 connectors lack a fixedly assigned address and, instead, receive it dynamically. This change is made from the KextsToPatch section of Clover. Read the post from foxbox.
      This has to be accompanied by 3 changes in the Graphics section of Clover: Orinoco in FB Name / Inject ATI / 5 in Video Ports. I have tested this solution in macOS Catalina and it effectively enables the 5 ports of the card but, since I only use 1 monitor, I have removed it and I am with Lilu and WhateverGreen.

      Guys,
      Don't mix 6.18 and 3.41.
       
      There are three different projects for monitoring temperatures, voltages, fans speed and other hardware parameters:
      Initially it was FakeSMC with plugins for producing SMC keys for hardware parameters for different hardware. But sometimes ago Kozlek separated own version of FakeSMC and producing new set of plugins while I stay with good working version 3. So..
      1. FakeSMC v3 with Hardware Sensors3  which I still supported.
      2. FakeSMC v6 (rev1800) by Kozlek and supported by Rehabman. AFAIK both are abandoned and the project is not supported. Or may be maintained by coauthors.
      3. New VirtualSMC by vit9696 with own set of sensors kexts. It depends on Lilu.kext. The project is in active development.
      All three project have incompatible interfaces sensors<->SMC so they are incompatible with each other.
       
      There are applications for monitoring hardware parameters and they commonly depends on these projects.
      1. iStat, iStatMenu, iStatPro compatible with real Macs because they use SMC keys just like those presents in real Macs.
      2. HWMonitorSMC by Navi (initial codes from Kozlek)  used in my HWSensors3.
      3. HWMonitor by Kozlek with graphics like in IntelPowerGadget used in his HWSensors version.
      4. HWMonitorSMC2 by Vector_Sigma tends to be universal supporting all project. It also may use sensors information produces by Apple graphics and by IntelPowerGadget.
       
      Let us discuss here differences and common ideas for this projects.

      This thread devoted to share information about different SMC keys found or investigated anywhere.
       
      What are they?
      SMC keys is a somehow language to speak between macOS and hardware microcontroller presented in real Mac and absent in Hackintosh.
      They inform macOS about Hardware ID and current status. Moreover macOS can write something through SMC protocol to control hardware.
      FakeSMC ( ©Netkas) is the driver to emulate this microcontroller on PC having no such device which is necessary to boot macOS here.
      But FakeSMC contain only ~20 keys while real Mac answers ~200 keys.
      Some keys we added by HWSensors project reporting temperatures, FAN speeds, voltages etc.
      Some keys are model dependent was added by Clover to be sure if user changed model in GUI then corresponding keys will be changed automatically.
      Clover sets
      LogDataHub(&gEfiMiscSubClassGuid, L"RPlt", &gSettings.RPlt, 8);
      LogDataHub(&gEfiMiscSubClassGuid, L"RBr", &gSettings.RBr, 8);
      LogDataHub(&gEfiMiscSubClassGuid, L"EPCI", &gSettings.EPCI, 4);
      LogDataHub(&gEfiMiscSubClassGuid, L"REV", &gSettings.REV, 6);
      LogDataHub(&gEfiMiscSubClassGuid, L"BEMB", &gSettings.Mobile, 1);
      BEMB - is a mobility sign. =0 -desktop, =1 - mobile.
      REV - SMC hardware revision, changes sometimes with Apple updates.
      RPlt, RBr and EPCI is hardware capabilities, noticed used in Intel HD drivers.
       
      Structure.
      All SMC keys consists of name 4 ascii chars as 32bit integer, type and value.
      Types:
       "flag", len 1
       "ui8 ", len 1
       "ui16", len 2
       "sp78", len 2
       "ui32", len 4
      "fp2e", len 2
      "fpe2", len 2
      "{rev", and others...
       
      List of known keys
      SMC_list.plist.zip
      More keys will be discussed in the thread
       
       
      Feel free to share you knowledge and ask about noticed keys.
