Maybe there's a workaround to patch the issue using OC.
Totally agree.
I'll do some tests, thanks.
Got a tip for us?

Note that if you've followed part 2 of the guide, then agdpmod=pikera is handled in a more "permanent" way with a device property, so keeping the boot arg would be redundant.
I'll correct me. With both versions I get scores that change randomly between 25K and 28K (before sleep). And in both version I guess that RadeonBoost kext won't be loaded (the output is the same):

Okay i understood and got the ROMTool. Do you have a Mavericks download?You need flashrom (or the GUI for it, ROMTool) to dump your bootROM and inspect the NVRAM.
flashrom
www.flashrom.org
If you can't disable SIP, you won't dump it unless you get 10.9.
I cant find it. Only the updates for it.
Okay. Had a backup drive with mojave on it and i could disable SIP, ran ROMTool (dumb system ROM) and now i have a untitled.bin. What do i do now?
I can start with this post below, but for complete diagnostic see the PM I've sent you.
OpenCore on the Mac Pro
Thank you @tsialex as always! Your knowledge overwhelms me! I have fixed my problem just reflashing BootROM using the reconstructed one that you made it for me. Now everything is ok again

That boot-arg is an aid to help get around black screen after booting. It patches the graphics device policy driver to rename a board-id variable. See here: https://dortania.github.io/GPU-Buyers-Guide/misc/bootflag.html#amd-boot-arguments.
Alternative is "agdpmod=vit9696"
Anyway, it looks like you already had added that boot-arg (via Device-Properties mechanism). So it looks like your black screen issue seems to be related to your RX 580 itself. May be try flashing it with Sapphires BIOS ?
Radeonboost does nothing for RX 580 in terms of performance boost. It's mainly for Radeon VII, 5700, etc.
So Radeonboost is not needed for your Nitro+ RX580.
OK, thanks. My gpu is a Sapphire, RX580 Nitro+. BIOS are two of them I can download from TechPowerUp, and I guess are the originals. I tried to install Pulse BIOS too, but ATIflash tool didn't let me do this.
In any case, now I know I can have boot picker using DVI/HDMI, I can live without seeng it each reboot (I need it occasionally to boot windows). And for performance issue... I mostly put the Mac in sleep mode, so normally I should have GPU in boosted mode. It was important for me to understand the limits of my new MacPro setup (after moving from Mojave to OC+Catalina). Obviously, if I can patch some of the issue, I'll be happier.
But in my transition to OC+Catalina, I must resolve another problem now: restore my windows installation. I had it on a MBR drive I converted to GPT with windows mbr2gpt tool, now I can see the drive in the OC picker, but windows won't boot... it hangs with a blue screen. In the next days I'll try to re-install windows saving my data and applications.
Try safe mode, that may able to fix Windows.
From memory, you are the first one to report that DP can't show boot picker. Is it possible for you to try another monitor / cable? Or even using another DP input on the monitor?
Or, for testing purpose, you may disable DirectGopRendering in the config plist and see if that make any difference.
You can forget about RadeonBoost, that won't help. Also, no need to care too much about GB score. That obviously affected a lot by the power saving function (variable clock speed).
IMO, it's much better to use Luxmark to check if the graphic card's compute power is at the expected level.
But is there any downside to leaving Radeonboost in place when you have the RX580?
@h9826790 Hi Martin. I am having a problem booting my cMP fro your latest package (0.72). I have tried three times (each time going back to Mojave to make changes) but have had to revert to the 0.71. I make changes to your config as follows: AQ > Ag for resolution, -v and latebloom 200/20 (works for me that way) in the bootargs and true for Bluetooth/Wifi kext (original mac card). I have also tried your package as is without modification on the last effort without luck. I am not sure where the problem lies but it fails to boot every time 100% (11.5.1). I switched to verbose because the long periods of no screen were a little too long and suspenseful and I wasn't sure what was happening but when its on I see that it stops very soon in the cycle, even before all the latebloom entries appear. Any suggestions as to what I might try to resolve? TIA
*edit. Did another mod - added new version lilu and whatevergreen kexts to my working 0.71 EFI and it still boots without any problem.

OK, I'll look how to force safe mode from my Mac. Even I guess windows will reboot alone in safe mode after a blue screen... but turns again in a new blue screen.
None of them, at the moment. I'll do it at the first occasion.
I tried to enable and disable DirectGopRendering more times. And I didn't be aware of any difference... I'm never sure if now it's enabled or disabled (I'm not on MacPro).
OK. I'll remove it from my config.
Seems something stupid, but I can't find the download. All sites I found, remains to this page: https://www.luxrender.net/#Download but can't see the download.
Potentially yes as it changes the way memory clocking is controlled (to reduce power consumption) thus potentially degrading performance when the demand is turned on. That is specially relevant to single screen setup. But it depends on the type of load. E.g. Luxmark is not affected by having Radeonboost but GB5 produced lower scores.
With multiscreen setup, the memory clock is set to maximum all the time and the power consumption shoots up per screen.
Radeonboost is a placebo for RX 580 users. It's like taking a drug knowing that it does nothing except make you feel better. 🤷♂️
Nailed it! Thank you Martin. Saw the word "Enabled" but didn't read on to the "false".
Can I ask you how this scores with Blackmagic Disk Speed Test? I've a Crucial P1, and seems it's performance are really poor for a nvme drive.
Thanks. With Luxmark, my RX580 performs pretty the same before and after sleep, slightly less then 15K samples/sec. while in the same, GB5 goes from 27K to 45K
It's not bad but not great as it is capable of:
It's installed in slot-3 (PCIe X4 lanes):
I tried it in Slot-1 (with the GPU in Slot-2) but made no difference to the speeds.
It is faster in a "newer" system (e.g. PCIe 3.0 bus). The same drive in my i7-3770K hackintosh yielded double the speeds ( ~2800MB/s Write and ~2600MB/s Read speed). In Windows 10 in that system, when new it was ~ 3000MB/s Read & Write ! I.e. their rated specified speeds.
So on a real Mac Pro5,1 something is holding back this NVMe's performance even with the limited PCIe 2.0 bus which has a theoretical maximum transfer rate of 2000MB/s.
...but we are getting off-topic here sorry.

15K is the correct score range for RX580. Then I will say nothing to worry about.
Apparently, it's GB5 too sensitive to the VRAM clock speed changes (due to power saving between different measurements), which makes it not a good to to measure actual performance.
Thank you for clearing that up. Then I might as well remove that kext.
on a sidenote: Is anyone in here driving a 4k monitor with an RX 580?
I know that the 580 is capable of 4k but it’s the very top limit, so I am wondering how well that will turn out in daily use cases.
My main Mac setup uses a 43" 4k TV (landscape) and a 25" 1200x1920 (portrait) monitor, both driven by a single 4GB RX570 (little brother to the 580). I don't play games, and I wouldn't try to do professional color grading using a TV, but this setup is otherwise excellent. 3840x2160@60Hz HDR, desktop extended onto 1200x1920@60Hz, no issues. Plays 4k@60Hz video with no tearing or artifacts. (That said, I rarely look at video on this system. I mostly have an absurdly large number of editor/shell/debugger/browser windows open.)
