You don't really have to read the 810 pages. As long as you read the first post you should be fine.
Try to install your windows 10 with this, if it is on a better secondary ssd.
Both my K3000m and K3100m run fine with Monterey and Ventura!Urgh, I would not ask you about this horrible Desktop Background...
The NVIDIA K2100M you cannot run proper with Monterey - stay on Big Sur,
the are no NVIDIA Driver support anymore in macOS Monterey - my info.
I think your Video card is faulty because of overheating (!) - hope you
have use the MacsFanControl Software, but NEVER in automatic mode !
If using the cheapest Thermal grease, you have 10-12° Celsius difference.
Sorry, where you answering me?
In my case, I try to be as careful as possible. My economic situation is bad, and my daughters need their machines working to study. They also want to be youtubers haha. First I search in Google, where normally it does not bring the entire search, then I do a specific search in ebay, amazon and finally in aliexpress, I look for the sellers with the most positive comments. So far I have been very lucky. When you can't buy a new machine, you have no choice but to have a little faith.
The wx7100 and K5100m are certainly not cheap, and for those on a budget probably not the best choice. @Tim_imac's info was useful to me. I got my GPUs for a more reasonable price, and as predicted by @Ausdauersportler, the AMD has been more future-proof than other cards. My main problem is that because the wx7100 is expensive and therefore less popular, there is a smaller user base to report upgrade issues or configuration recommendations.

I've been holding off moving from Monterey to Ventura for initially OCLP was reported to have may issues with that. It is tough with everyone running different cards and different iMac models, to know if issues reported apply. Reading threads specific to the task, such as "macOS 13 Ventura on Unsupported Macs Thread" can be worse, for most of the comments are from non-iMac users. It sounds like there may still be a few issues, but today I take the plunge and upgrade to OCLP v0.6.1, then Ventura. With a recent TimeMachine backup I figure I can always reinstall and restore if things go terribly wrong. Wish me luck.
My iMac is the same exact config as your Scooby. Ventura has been pretty stable for two weeks now on OCLP 0.6.1, no issues with install. I have a BCM94360CD I was planning to upgrade to, but it's not necessary as wifi and Bluetooth work fine with the existing card.The wx7100 and K5100m are certainly not cheap, and for those on a budget probably not the best choice. @Tim_imac's info was useful to me.

K2100M with Nick[D] vB flashed BIOS works perfect on Monterey with my Late 2009 iMac 27" 11,1.Urgh, I would not ask you about this horrible Desktop Background...

I usually search "WX4150 MXM" or else PCI cards with fans on them pop up. So just add "MXM" to your search after the card model number. Also try to study some pictures of MXM A and B cards.. they generally look pretty similar and you'll be able to tell them apart from the others that won't fit. I'm in the US so I only use ebay and only like to buy from US sellers who offer returns. I don't trust aliexpress because I've ordered things from there that have never shown up and it's a pain to get your money back. Ebay has better guarantees and protections.
If anyone is interested I have updated and modified the awesome grml-linux vbios flash boot disk that @xanderon shared with the macrumors community.
The changes include adding amdvbflash, thanks to @Ausdauersportler add-on, all the current ROMS from post 1 and a local Backup directory to store your backed up original ROMS directly on the Bootable USB using the persistency function in grml as default.
By doing this the directory structure has changed so please see the detailed guide below on instructions for using this modified bootable USB.
Create your USB using my modified @xanderon boot disk and connect to your target machine via SSH as outlined in @xanderson post HERE.
At root type:This will list list your mounted disks and is important as this disk order may change, sda/sdb/sdc, depending on what disks you have connected, how fast they are loaded by GRML etc, therefore the path to your working directory may change. You will see a example of this if you look at my terminal.txt file, I flashed 1 AMD and 1 NVIDIA GPU on seperate Macs.Code:lsblk
In terminal copy the path to the root of your Flash USB, Example:
cd paste and add /flash to get to the directory:Code:/lib/live/mount/persistence/sdd2
Press enter, you will now be in your working directory.Code:cd /lib/live/mount/persistence/sdd2/flash
In this example I will be using amdvbflash to backup and flash my stock AMD apple vbios.Code:root@grml ~ # /lib/live/mount/persistence/sdd2/flash
1st - lets look at the working directory:
2nd - Verify your adapter is recognised:Code:ls
3rd - save a backup of your original bios to the Backup folder on your USB.Code:./amdvbflash -i
4th - Verify the bios is saved to your Backups folder:Code:./amdvbflash -s 0 Backups/Original_Vbios.rom
Now if your paranoid that when you shut down your bios will be gone you can stop, shutdown and actually check the USB drive Backups folder.Code:cd Backups ls
View attachment 1749833
5th - flash new bios for example:
Code:./amdvbflash -f -p 0 AMD/WX4150_GOP.ROM
WARNING: There is no pause asking you if you wish to continue as in nvflash so make sure you have your backup and are flashing the correct ROM.
You will be greeted with some code similar to this verifying the process is complete:

Shutdown and hope for the best
Code:shutdown now
For NVIDIA cards the process is the same but the nvflash_linux commands will be different see my attached Terminal example.txt if you need more info. Also attached a quick visual guide and both Nvidia/AMD flash tools help text.
Enjoy.
