Make sure you invented an NVMe to SATA adapter first.

iNitialE - You're posting this here too? You failed to mention that you're powering your Vega 64 from a SATA port from a drive sled. We gave you the answer in the OpenCore group - perform the pixlas mod before you burn up your backplane. There is no "config" - there is nothing else to do, "bro".
PS - Based on your screenshot, you're running an old version of OpenCore.

A VEGA 64 fully powered by the backplane, seriously? I smell crispy power controller chips.
I find that OC on my Mac Pro 5,1 with updated WiFi/BLE and GPU cards works more reliably than a patched approach with boot-args="-no_compat_mode" BLE is especially improved. I hope we can resolve the NVmE issues of 11.3.
Has anybody found a solution to the USB 1.1 problems and overall USB reliability issues? Is there a way to inject the Catalina USB drivers?

The only USB 1.1 problem I'm aware of is the inability to hot-swap. USB 1.1 devices work fine if connected at boot time. I only have one USB 1.1 device - my UPS - so have tested what others have reported. I'm not aware of any other USB-related issues, and I move massive amounts of data across USB3. As of 11.2.3, I haven't had any USB issues besides the USB 1.1 hot swap issue.
i apologize if this has already been answered within this thread as I haven't visited the forums in eons but this is presently at 318 pages long and the search function just has too many hits with not enough context within the hits to indicate it has the answer:
Is OCLP (OpenCore Legacy Patcher) an easier method to install OpenCore for Big Sur, or is the method described on this first page of this thread the recommended method?
I don't use NVMe; I have standard SSD's mounted on a Apricorn Velocity Duo X2

Others can comment on OCLP, I never used it. FYI many of us are using the following OC package by @h9826790 which is primarily focused on enabling AMD hardware acceleration but has also been setup with newbies in mind.
Activate AMD hardware acceleration
I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 0.7.9] For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in...

GPU hardware acceleration? In terms of using video editors, such as FCPX? Or simply Apple display acceleration?
I have a flashed 280X for Metal compatiblity with boot screen, so does this package allow using newer and better AMD cards WITH boot screen? Perusing the thread suggests this (which also mentions using an unflashed GPU). I would definitely use this method as I want to upgrade from the 280X.
I stumbled across OCLP in the general Big Sur thread and someone with a cMP mentioned using OCLP to run Big Sur with no issues but I wanted to check in here in the cMP thread to see what others are using to run Big Sur.
Is the thread from hp dealing specifically with getting graphics hardware acceleration working for non Apple Metal-blessed GPUs, whereas this thread is more general installation of OpenCore?
I originally had a Sapphire Pulse RX 580 but had to downgrade to a 280X for Metal-compatibility/boot screen with the release of High Sierra, but would like to reinstall it under Big Sur if I can regain the boot picker screen. Want hardware graphics acceleration too, if this card normally wouldn't support it.
Like @cdf explained, this thread is for a comprehensive hands-on approach to install OC (the guide covers everything and more than everything!)
For a less hands-on approach (i.e. for the newbie or/and the impatient or/and the lazy?
), you can use @h9826790 package as I previously mentioned. In the post I linked above, @h9826790 explains everything about the package.Yes, you can re-install your unflashed RX580 and with either of the two OC install options you will get boot screen. Both OC install options have excellent guides!
Got it!
I don't mind getting knee-deep in to it if need be (heck, flashing 280X's for both of my cMPs required a lot of hoops to jump through), but in the end, I just want it to work so if the hp method makes it easier for the laissez-faire among us, I'll take the path of least resistance

BTW - avoid Big Sur 11.3 (soon to be released). Both 11.3 and 11.4 beta versions are currently not working on cMP, and very likely the final 11.3 release won't work either on cMP. But don't despair! The cMP gurus of this sub-forum are hard at work to fix that and more! 😀
Big Sur 11.2.3 works perfectly on cMP, so that's what you want to install. If Apple has already released 11.3 by the time you plan to upgrade, you can find 11.2.3 here:
Install mac OS 11.2.3 20D91 : Free Download, Borrow, and Streaming : Internet Archive
macOS 11.2.3 Installer
archive.org
EDIT: Correction, if your boot drive is in one of the four SATA sleds then my understanding is that 11.3 should work fine. If you have your boot drive on some PCIe board then 11.3 won't boot.

USB 3 AV streaming like a Brio webcam stutters when plugged into a hub. Ok plugged in directly. Occasionally all USB functions except legacy plugged in at boot disappears and you have to reboot.

My boot drive is on an Apricorn PCIe card, so this may not boot under 11.3.
No worries, I have 11.2.3 already downloaded as I was about to use OCLP to install it, then I came across these threads...
However, since it's a standard SATA SSD, I could install it in a regular bay via a 2.5" sled that I already have...
It does not matter. As long as you have a PCIE device in another slot it may still prevent boot/panic.
but in the end, I just want it to work so if the hp method makes it easier for the laissez-faire among us, I'll take the path of least resistance
Yes, that's what I did when I installed OC few months ago, partly due to impatience. But since then, I have been regularly going back to @cdf OC guide in the first post(s) of this thread to learn more about OC and to understand more the how and why @h9826790 setup his OC package as is. Eventually I aim to be capable to manage/tweak my own OC update settings. @cdf (and collaborators) did a superb job with the overall cMP OC project and in creating a very detailed and easy to follow and understand guide here in this thread. Thanks @cdf (and collaborators)!
Bummer. This means I am stuck on 11.2.3 or go back to Catalina full time. I have both installs plus Mojave and Windows, but like Big Sur best.
To my understanding, that 'no entry' screen only ever happens when the Apple bootloader directly tries to load an officially incompatible OS (e.g. Big Sur). If so, that means that when you got that screen your MP did not start OpenCore first but attempted to directly start Big Sur. Which probably would mean that your OpenCore is not installed or blessed correctly.
