it is definitely an afr card, in my case an amd m6100.
Are you using OCLP? If yes, when you select the post install root patches it will show to you if you need any patches (and what these patches are) for your system. For example, I upgraded my system to Big Sur with OCLP and when I selected the post install root patches there was no need for any patches. Everything was working out of the box (wifi, GPU etc.).
Are you sure you are booting your iMac from the USB stick? Disconnect all HDDs/SSDs and only plug in the USB stick and ethernet cable before pressing the power button. Or check your router settings - is the router blocking port 22?
It just came from ebay, seems it is MXM-A card but in my imac is bigger MXM-B card... Should i try to instal it or it cant work?Welcome!
Go back to page one and post #1 go this thread and read...of hit the link in my signature. We do not promote sellers, we do not search cards for you, the most promising long term options are the AMD cards WX4130/WX4150. Even the M5100 will work, but is more difficult to setup. Just read all the docs...
We do not support video guides, but I guess most of them are fine. I do not have the time to watch YouTube all day long. If you have a question about a guide comment on YouTube, not here
No dremel-ing, but possibly you'll need the 'special install' as linked in the post 1 for K610M. (A 0.5mm-1mm copper shim for proper thermal contact between GPU IC and heatsink...)
Thanks again for your help, Madvinegar! For now, I decided to reinstall stock High Sierra, then go with Dosdude's Catalina patcher, and everything is running very smooth. I will probably end up eventually going back to Monterey using OCLP, so thanks for the tips! It's a lot of fun for me to just experiment and see which setup is the smoothest and I like the best. Appreciate it!
there was written this:"problems with cards: Unlike the NVIDIA family where we get each week several reports of dead cards we had so far only two reports showing a not properly working Dell WX4150 and a HP WX4170 - the problem have been solved by adding more VRAM support. Unfortunately we now have to chose from several published versions."
WX4170s are (currently) very hard to find. You can mount a MXM-A card onto the bigger heatsink, possibly by adding a copper shim between the GPU IC and the heatsink. (I would/did use a copper shim with the WX4170 too, by the way.)there was written this:"problems with cards: Unlike the NVIDIA family where we get each week several reports of dead cards we had so far only two reports showing a not properly working Dell WX4150 and a HP WX4170 - the problem have been solved by adding more VRAM support.

So I can choose only hp WX4170 (which is bigger MXM-B card ) if i dont want to risk another crush of nvidia card? I search it on ebay and cant find any link
Definitely. The 21.5' model does not have the 'big' 27' model heatsink. (Those 27' models that originally came with a MXM-A card will - of course - fit any MXM-A card from post 1 with no modifications...)
I believe the AMD wx4130 and wx4150, even if they are MXM-A cards, they need the copper shim mod because they are flat.
With the heatsinks intended for the MXM-A cards (all 21.5' heatsinks, 27' heatsink models with HD 5670 or HD 6770M GPUs), they don't. Trust me.
Just to be clear, I don't have personal experience with these cards (wx4130 and wx4150). I just read what the 1st post says. And the 1st post does not say that the copper shim mod is required only in bigger iMac models with the larger heat sink. So it implies that the copper shim mod should be done in all iMac models/heatsinks even if they are 21.5" or 27" etc.
I disconnected all hdds , my imac online and have ip but I can’t ssh , is there any way to test if my router does? , and how to unblock if it blocks port 22
I admit, it's been a while since I read the 1st post thoroughly. But as I remember (from the last read) only the Nvidia K610M (possibly) needs a shim with the smaller heatsink (K610M is really flat). Other MXM-A GPUs have enough thickness to make proper contact with the 'MXM-A heatsink'. Original MXM-B cards in 2009-2011 27' iMacs were thicker, hence the necessity of a shim in case one wants to fit MXM-A cards onto those MXM-B heatsinks. (Side note: Adding a shim will in all cases increase the thermal resistance, but by much much less than a potential air-gap, of course. If the GPU IC makes a properly flat contact, no shim should be the way to go...)
Can you at least ping it (
ping iMac-ip-address)? Otherwise it depends on the settings of your router and you'll probably have look for help on that elsewhere...I tried upgrading from an M4000 to an M5100. My 2010 27 imac can boot into safe mode okay. However it stops normal booting at about 1/3 way with the apple logo and then the screen goes black. Did you experience something like that?Wanted to thank everyone who built this amazing thread, I was able to follow and upgrade my 2011 iMac to macOS Monterey, also upgraded the graphics card to M5100! After a constant battle over the last few days finally (mostly) everything works smoothly and I am really excited that I can use this wonderful machine for a few more years to come!

The only thing that makes it less than perfect is, the wifi seems to be not working as expected, shows On in the settings but is not able to detect any wifi network to connect to.
I am using a TPLink adapter to connect to the wifi network, a nice workaround for now and too afraid to touch the configs anymore..
