In the case of the MacPro OCLP is just an installer that makes it easy to install OC.
OCLP uses that, but does a lot of reconfiguration. To understand more about what it does you can read this https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/

That's the one with the open core boot loader. When you click on boot loader it take you to the OpenCorePkg page where the 0.078 release is. Is that what I should download to get started?

I am a bit confused, do you want to do a manual configuration and not use OCLP? In that case you have to read the Introduction and do the Basic setup as outlined here https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814
Oh, sorry about that. Just looking at both as I have no idea on which to use. I do know I want to use the most simple to install. I did this one that you suggested (https://dortania.github.io/OpenCore-Legacy-Patcher/START.html) and messed up on that one, which seemed to be very simple. Evidently I missed or didn't something right on it. I will probably try that one again on my 2009 5,1. Like to do it on my 12 core but I'm not very confident with doing that yet. I have 3 6,1s that I use majority of the time but still use the 5,1s also at times. Listen, I really appreciate your help on this. Sorry again about any confusion, I do that to myself all the time.
I no longer have the 7970. Have a RX 560 4gb instead, which has quit working for some reason. I got it to work one time after this fiasco but the colors were washed out. The GT 680 supposed to work up to Big Sur, I think. I flashed it so it has the boot screen. The 560 doesn't. I also have the old gt120 Apple Card that has always been flawless and even up to Catalina. I don't think it suppose to work past H Sierra but it does. Have even installed Mojave with it. So I just may try it to start off with on snow leopard. The 680 has been perfect also. The 560 is the one giving me trouble now. Will try the OCLP that you gave me again and just hope for the best. Oh, what os can I do the OCLP. Or is it best on Mojave or up?
Thanks
Thanks
Personally I would try Monterey 12.2 though many prefer Big Sur while Monterey is going through a somewhat frequent upgrade cycle. You will not need SurPlus with Monterey (which I think is what you are calling Big Sur Patcher)
If you have no idea what you are doing, the GUI offline version will be the most user-friendly. Build OpenCore configuration and install it to your boot drive.
Reboot the computer to initialize Open Core.
You may want to use an USB installer (note: apparently 12.2 does not work for creating an USB installer, install 12.1 and then update) or you can use the standard procedure.
As you probably know, the MacOS bootpicker (this thing allowing you to select the boot disk while the computer starts by pressing option on power on) is no longer relevant and you have to use the OC bootpicker, which OCLP will conveniently install for you.

Thank you sir.....unfortunately I have no idea about this. It's all new to me and just wanted to do it right without trial & error. If I remember correctly, I used 12.2 on the usb installer and you're right, it didn't work. I've done a lot of upgrades on my Macs but never anything like this, just don't want to mess up again.
Thanks you for time, I appreciate it.

It is extremely hard to mess up with OCLP if you do not press anything extra besides "build and install". The rest happens automatically, your only concern is to pick the right hard drive / SSD for opencore to install to. This will be your current bootdisk (the one you are looking to upgrade to a newer system).
build/install
reboot
run Install MacOS (whatever flavor you may fancy) .app from App Store.
Wait.
After successful installation (your screen may look weird, your peripherals my not work as expected) use the OCLP Patcher again, now only using the Post Install Root Patch option.
reboot
Job done.

Tha's easy for you to say, lol. If something goes wrong, do I have to completely remove OCLP or just re-install?
Erase the USB stick and re-do it? Hopefully, I won't have to do any of this but in my case, don't count on it. This is probably not as complicated as I'm making it but just want to be able to do something if it does go sideways.

You don't install it on a USB stick. You install it to a drive you will be using to boot your computer regularly.
In an unusual case of something happening with the installation you need to mount your EFI partition located on the above disk and delete the OC folder.

This is the one I have been using, which has the usb stick to download. I really prefer not to use a usb and download it to my hard drive but I haven't seen anything where it says to download it to my hard drive. I guess I missed that. I went through this again last night. Went through all the prompts including making the usb. Got to reboot and option key. Held this option key for 9 minutes (yeah, I know), never rebooted let alone show the boot picker. So back to square one, again. So I just thought I would do Catalina instead. Downloaded patcher for it, installed it as usual, then get a window "15.7 cannot be installed on this computer" or something to that effect. Now I have installed Catalina on this machine a few times and just installed it on my 12 core last week. No problems whatsoever so I have no idea (again) what's going on. This time it is telling me to disable sip which I didn't do on my 12 core. I have used my Radeon RX560 (no boot screen) and my GTX680 (boot screen) for the OCLP and it doesn't seem to make any difference. I know Monterrey doesn't support Nvidia now so I used my RX560. I have Mojave installed and it runs like it should, it just won't let me install anything now. I think it's haunted, lol.

What you are reading is about creating a USB INSTALLER FOR MAC OS, not for OpenCore. OpenCore goes on your main drive.
You have been told again and again, that your job is to download the Open Core GUI APP and then:
Why are you looking for ways to overcomplicate things and make it harder instead of easier? Installing MacOS from a an app downloaded from App Store is exactly what OpenCore is about.
You probably have polluted your PRAM. Try alt option P R, a couple of times. At least three.[/QUOTE]
Hello, I have Macos Mojave 12.5.1 installed on a Mac Pro 2x3,33, 64 GB Ram using OCLP version 4.10, almost everything works correctly, there is only one thing that gives me trouble, I have an RME FF800 and when I use it when I choose the driver in the programs that I use for music I can't use it since all the channels start to make a tremendous feedback noise. Only once I have been able to use it well, but as soon as I turn it off and start again the problem persists. I think it will be an OCPL configuration problem, since a Macbook pro with an official Monterrey installation works without any problem. Could you tell me something about it? Would it be better to use MartiLo's packages? It is much easier for me to use OCLP since you do not require any intervention in the configuration plits, I left the hackintosh topic a long time ago, and I am not very up to date.

You mean Monterey.
You are running an old GPU which I believe is not supported even by Mojave
OCLP modifies Monterey to make the GPU work and the official Monterey is not the same as OCLP patched Monterey.
Martin's package will not have these patches so you will not be able to run Monterey with that GPU.
You will need to check on forums where fellow musicians hang out to confirm but it could be that something in the OCLP patching to support your GPU could be in conflict.
OCLP probably also has to inject some kexts for FireWire to work in Monterey which can be replicated in Martin's package but would likely lead to the same outcome.
If you have or can borrow a supported GPU, you should try that first to exclude that angle.
Radeon HD 7950 is fully supported by Monterey. It's the same Tahiti GPU as the D500 and D700 of late-2013 Mac Pro.
Works from 10.7.5 (with the previously available drivers by Sapphire, removed from the site last year) to 12.6.
Hello, sorry for the error, it is Monterrey 12.5.1 that I have installed, the graphics card is fully compatible, it is Mac edition that works perfectly in Mojave and in Big Sur as well. The only problem I have with this installation is with the RME fireface 800 FireWire card, which although the system recognizes it perfectly when using it, I have feedback on all the output channels. For the rest, everything works correctly (I think that sharing the screen with the iPad does not work) but the universal control, bluetooth, wifi, etc...
