Thanks!
Wow, a 123 ko DSDT. That's light! And very simple to setup.
NVRAM implementation doesn't look different from others I've seen. So I suddenly have a doubt. Installing a Monterey beta is a good sign, but have you tried to create a custom entry in NVRAM to see if it survives across reboots? (Terminal: sudo nvram MYVAR=THIS_IS_A_TEST, reboot, nvram -p and look for your custom variable, which can be anything as long as there was nothing of this name before—so no need to clear beforehand with "nvram -c".)
Else, I just add a SSDT-PMC to fix that and finish an updated EFI with regular OpenCore. Workstation/server boards are typically slow to boot, but not using the debug version will shave one second or two. ;)

Hey all,

I'm having a few lingering problems with my T5820 Hackintosh. I'm running Catalina and it is in the following state:

1. It doesn't seem to boot consistently. It will generally always boot in verbose mode, using the -npci2000 or -npci3000 flag. It won't boot at all without them. And it won't boot without verbose mode... which I find a little weird, and frustrating.

2. USB, audio, network and HDD ports and all of my PCIe devices seem to be working fine.

3. I am still experiencing a strange sluggishness when opening the "about this Mac". It will show all the details, but it will take 2 or 3 seconds for my AMD WX7100 to appear in the list. It just shows a blank space when first opening it.

4. I seem to be hitting a limit of 12 sound devices in my audio midi/sound preference settings? It that a known limitation of OSX? I have an Avid HDX card, Blackmagic Decklink Extreme 3D & RME HDSPe MADI PCIe card in the machine. There are the two or three 3.5mm sound ports in the Dell T5870. I also have a variety of virtual sound cards (Dante Via Stereo & 16 channel, Dolby Audio Bridge). The main problem seems to be the 6(?!? it only have 4 physical ports) HDMI audio outputs associated with the WX7100 which bumps others off. For example - the RME HDSPe control and hardware panel shows the RME MADI card. I can control settings, change sample rates and clock sources... but it doesn't appear anywhere in the system as a usable sound card. If I create a Pro Tools Aggregate device in Audio Midi Settings, the Black Magic Extreme 3D will disappear from the list but still remains accessible through the Blackmagic Pane in preferences.

Strange, eh? Is perhaps point 4 related to point 3 in some way?

5. There seems to be a variety of 'err' messages in verbose mode during the initial loading of OSX, prior to the +++++++

I have tried fumbling my way through clover configurator to see if anything in there might be amiss, but I'm not across all of the functions. The EFI is basically the one Sylvain83 shared for catalina, with a couple of changes. The profile is an iMac Pro 1,1 rather than a Mac Pro 7,1. The drivers and Kexts have been updated to the most recent, where available. It is still built on Clover version 5119, as updating it to 5142 would prevent the machine from booting OSX entirely. It would make it to the 5142 clover screen, but then kernel panic/freeze or crash before getting to the +++++

Any insight, hints or advice would be flipping amazing. It feels like I am so close, but also so far away... haha.

npci=0x2000 seems to be required on all C422 or C621 systems. But that's unrelated to verbose boot ('-v'), which is not in your config.plist—I suppose you trigger it from the Clover boot screen.

You have both AppleALC and VoodooHDA, which is one too many, and inject '7' for audio although there is no layout 7 for ALC255. @Sylvain83 could not find a fully working layout, so maybe it's VoodooHDA which does the trick?

Catalina and later spit out an number of 'Err' which are not actual errors.
Failure with Clover 5142 may be due to wrong setting for the OpenCore-derived Quirks section.

I'm not familiar enough with Cover to suggest improvements to your EFI. But I may help with OpenCore.
If you're willing to try, here is an OpenCore 0.7.5 EFI with VooddoHDA instead of the usual AppleALC.


Note Serial numbers should be kept private. Please edit your above post to remove the EFI folder and replace it with a version without serial numbers in config.plist.
