Did you ever try out that K2200m. I bought one by mistake and now I don't know how to flash it. Help please.
Got a tip for us?

This is a Maxwell based card and there are no drivers within MacOS available. On this thread you will not find a BIOS to flash and there will be no in future. Read first post about Maxwell cards...
Maxwell is the name of a Nvidia GPU chip family.
This K2200M is a Maxwell based card and there are no drivers for Maxwell based Nvidia cards within MacOS available. On this thread you will not find a BIOS to flash and there will be no in future. Read first post about Maxwell cards...
There is no gain to have a BIOS when you cannot drive the card from the current MacOS versions.
Please start reading this thread on page 1 and post #1 - you will find everything what is known and what is working!
Nvidia card > You MUST have a Kepler family gpu
Tested many times, 870M_Clevo_BR.rom has a startup screen and macOS also has brightness adjustment. Both macOS and windows TDP work at about 50W. TDP does not reach 100W at full load. The video memory is locked at 405mhz and there is no reason why. gtx880m test score is normal, can work with full load 115W TDP

just orded a dell wx 4150 hope all gose well wen i flash it and put it in my imac 2011 21inch i have. should be here on the 20th but if that card dose not work. i will be getting a wx4130 with with number 00D and i here that will most likey work.
@Ausdauersportler, can you help me? I did Volume root, replaced the kexts and AppleGVA.framework files, then used these comments in the terminal:
after reboot, I can see the replaced files in the main Volume but still Hardware Encoder is not working

Nice let us know. If your wx4130 works.
Today I installed Catalina, used the new opencore.
Used the normal Polaris boost
Had to find how to fix the sleep. But I install all the kext. And it looks like all works like it should be.
I'll have to run the benchmark test. But all seems pretty .
And Catalina looks great.
Really impressive.
For my 2009 27 imac I perhaps also going to do a gpu update.
would just be a second machine. Don't need the horsepower but it would be nice to bring it to Catalina. So it can have a use.
not sure on what card I'm putting in.
Think about the 5100
or a 860/70/80 card.
but that's future.

thank you once again, two K4100M rocking Catalina.
happy user here, I'm discontinuing my journey here
next step is to hook up an eGPU 1070 ti and the switch to Big Sur. but I will continue to read the awesome progress here.

I'll be interested to see your results, but it is very likely they will both not work in the 2011. My WX4130 only works in my 2010 and many others including @highvoltage12v and @internetzel have tried extensively to get them to work in the 2011 models. The first page warns about this, but if you are able to get them to work, I will certainly be very excited.
Thats cool tho I will let u guys now if it works for me ithe wx4150 is going in a 21inch imac mid 2011
I would be very excited to if it will work in a 2011 imac it would be neat if it works tho
I have a 00D card working in my 2011's the AMD/2011 it will always be a huge ordeal with these WX cards.
I think on the first page. We should highlight that card in RED. It causes us nothing but grief in these forums. Especially, when you consider that there are so many other choices.
It's the fact that there are so many variants makes these cards miserable to work with.
I understand that I ordered a wx 4150 that was like. The blue one u showed me but it's a green one. and it a dell one it's the 00 version if that one dose not work in going to buy the 00d one. I would off got that one 1st but it would took to long cuz I would of. Ben coming form China
No...I have a spare blower fan - I have removed my optical drive and was thinking of powering through the spare sata. However I probably won't need to do that - I made a makeshift shroud to better direct the ODD fan blower through the GPU heatsink fins - and reseated/pasted the heatsink on the GPU - performing better and boosting.
This is nice tho so a gtx 880m can work in the imac I thought the 880m was a Maxwell card tho or am I wrong about that
Hello do you have a gtx870m? Test to see how much the video memory and the core at full load can run at the highest frequency with full load TDP. I tested that the gtx870m video memory is locked at 405mhz and only 50W TDP
The test result of GTX880M is about 115W with your full load. The GTX870M test memory is fixed at 405mhz TDP 50W and cannot run at the highest frequency to reach 100W TDP with full load.

The dell version of gtx880m should be able to be used directly, but there is no boot screen. The MSI version of gtx880m is not sure, and the Clevo version of gtx880m is definitely not good enough to flash vbios.
