iM 4,1-14,4 2011 iMac Graphics Card Upgrade

It is not the slot, it is (probably) the functionality: For an unknown reason (to me) the core2duo machines will not work the same way as the later i-series Intel based machines. If you watch the page one you will find out that there are only the 21.5" 2010 and 2011 models listed.
I cannot find a positive or negative post on it, but probably some of the more senior members can comment on this? I am following the story for seven month, only. Just remember that I once asked about the late 2009 27" core2duo model and got a non positive answer...
Edit:
I found some posts about the CPU, search the thread for "core 2 duo" and limit results to this thread, only. The cards will (likely) work, but the vBIOS features like boot screen are said to work not! So you can buy a K610M and use it with or without a modded vBIOS and it will most likely run. If you get no brightness control the smaller 21.5" display is unlikely overheating the system in the same way a 27" is able to do.

I can confirm that 2009 core2duo versions do not support these video cards. I tried the k1000 with Nick's rom. Only get black screen this is on BOTH the 21" & 27" both with core2duo cpu. Same card works fine on my 2010 i3 and 2011 i7. Idont have any I seies 2009 iMacs. Bummer for me as I wanted to swap out the hou on my 09 27". Oh well
Does the 21.5" Late 2009 C2D still run with a black screen with the original HP/Dell rom?
I have tried a FirePro "6770" and got blank screen. Machine booted but nothing to internal or External display
Could you pls support for vBIOS with K3000m & W5170 run on iMAC 2011. Thank you.
Nobody claimed or promised that these card will work! We had a discussion about that but there was no explanation found until now. @highvoltages owns three of these non working cards, too. You are not alone. For that reason we added this note to the first page:
Note - (Some of) These WX 4130/4150 are not detected by the 2011 iMacs for some reason, and therefore are currently incompatible. Even worse some models are not detected in any iMac model late 2009 to mid 2011.
Hi All,
Quick couple of questions:
1) Is a K2100M likely to work in Big Sur?
2) When it comes to installing the custom drivers, is there any reason I can't do that *before* I remove the old graphics card, so I can do it with the screen active?
Thanks

No idea on 1)
But on 2), you are not installing custom drivers, you are flashing the card, which clearly this can only happen if the card is in the computer.
1)
There is still Nvidia support in the Big Sur Beta, so likely yes. Read the Big Sur thread on this.
2)
Read first page and first post about flashing options. Everything has been documented there. Using a CH341A you can flash before installation.
Ah yes, you’re quite right! Sorry if that seemed like a stupid question, there’s a lot to take in with all the various options.
At least this thread is using the first page as a guide and collection of knowledge - there is nothing stupid in asking questions. The answers are sometimes short like mine
Thank you very much for your replies.

Actually I have no particular issues with GPU: I can see 1080p .mkv file easily with VLC player and 1080p videos on YT.
I have only buffering issues during a 1080p 60 fps videos on YT (I use chrome browser and I have already disabled hardware acceleration).
I have noticed high CPU usage during these videos on YT (no problem with VLC).
I don't know sincerely if it's a primary CPU issue (old processor) or a secondary CPU issue (not enough VRAM memory).
Best regards

Hey. Tell me where to find the instructions for the firmware of the nvidia gtx 780m video card? Can I change the brightness at the moment using the keyboard?
No brightness control with the current vBIOS on the 780M and as I wrote some minutes before just take look on page one and post #1 for all the details.
Hi again,
Big thanks for testing and verifying.
After some more failure from my side I finally understood that this whole issue probably is related to me running a 2700k processor in my machine. I really do think that I am installing the kexts correctly, but after more testing I realised that sleep does not in fact work either, so then of course hw acceleration will fail also. Videoproc displays "Graphics N/A". Hackintool shows "Intel Generation ???" before installing the sleep kexts, but says Sandy Bridge afterwards.
Please let me know if I am wrong here, but maybe this information could be of interest to someone who is planning on buying a 2700k processor.
However I can report that upgrading Mojave to the latest security patch 18G5033 does not cause black screen issue. The screen is working fine without any modifications.
If anyone have working sleep and hw acceleration with mojave, 2700k and 780m, please let me know!

According to Intel your CPU supports QuickSync which is what you are looking for. Unfortunately I cannot confirm if there is any kind of Apple ROM or kernel extension support needed to achieve sleep and iGPU aka QuickSync support on CPUs that never have been used in official Apple products. The i7-2600 will work as fast as your i7-2700k, I never understood this race for the last additional 100MHz of core frequencyHi again,

What I can tell you honestly: I had never problems to enable QuickSync on Catalina on at least 10 2011 system with more than 30 cards in test, but the Mojave installation yesterday killed my nearly. Still not understand why I could not make the basic installation working with the iGPU.
Hello to all!
Because of our growing list of working cards (great thanks to @nikey22 and @internetzel) I reorganised the first post and deleted some redundant information. Still not happy with it, because it could have more structure and the same information using less story telling and redundant text fragments coming from copy and paste actions. Feedback is welcome. Error corrections, too.
The language thing should be corrected silently, I will not become a native AE or BE speaker in this life!
Happy reading....
