This is not about understanding things. This is not the single iMac thread and there is something like a search machine outside. Collaboration does not work if a few are the sources and all other are consumers, only. You found this thread, you will be able to find the threads about the other problems you have and even then reading and searching before posting a „link please“ is the way...
If you install Windows in legacy mode sound works just download the right driver for sound but you will have to install windows from dvd drive only way to get lagacy.
I had same problem with this but not only in logic this was everywhere pink looking and unreadable this don't work properly it fixes one thing but you get pink unreasonable boxes.
Same problem on my imac mid 2011 27 pink colour and unreadable why make something that don't work properly. No fix for it.
Very easy to install windows 10 in bootcamp but do it in legacy mode from dvd drive to have sound in efi mode you won't have sound.
Don't do it in uefi mode you will have no sound do it in legacy mode from dvd drive everything works.
Did you read the OpenCore post about windows UEFI sound? Welcome to this thread
So on a whim, i picked up a K1100m for cheap and then I got myself thinking on whether that card is worth installing in my 2010 iMac that sports and i7 2.93 GHz CPU + 1GB Radeon HD 5750 graphics.
I completed the recent upgrade on my 2011 iMac that had the 512 MB HD6750 graphic and swapped in a k2100M 2GB graphics and the improvement was noticeable. Not sure if my FCP transcode jobs were any faster with the new GPU swap but all things video seem to run better.
I'm having doubts on the k1100m upgrade for the 2010 and wanted to know if anyone has had the same configuration as my 2010 and did a similar upgrade and what were the results like? I'd hate to tear into my primary workstation only to be disappointed by the marginal gains (if any). I probably should've picked up a better card but the k1100m was a good deal that I couldn't pass it up.
Thoughts?

I think the 5750 will be better than the K1100M and slightly better than the K2100M, you can be of service bench marking your 5750 and then compare it to the K1100M... a lot of work...
Maybe a better bet would be to go with the WX 4130. (You got a good deal on a K1100M but you have no real idea what its state is until you install it in your iMac).
If the current system is working and you are productive it seems difficult to justify the effort, unless you absolutely need Metal supported GPUs for an OS upgrade.
But it is truly your choice.
I have successfully installed a k5100m in my imac 27".
Althogh i have a problem in windows 10, since GPU-Z shows my card to be running at only 324mhz max in windows.
Unigine Valley also reports much lower FPS in windows in relations to osx
At windows boot i was getting
"ERROR: Valid MXM structure not found. P-State Limited to P10."
I had Windows installed as mbs/bios, so i reinstalled it in gpt/efi but i still have the same issue.
Also, when reinstalling Windows as UEFI i had to manually disable Intel HD driver to installed automatically as this was causing a black screen, after the driver was installed automatically.
I have already tried to set the nVidia driver to Power Management Mode = Maximum Perfomance in nVidia Control Panel with no improvement.
Any suggestions?
I thought about re-flashing the card, but it does not seem a good idea.
Also had a look at DSDT, but the posts i found do not point to my specific issue

I have successfully installed a K5100m in my imac 27" 2011, but i have an issue with my Windows uefi installation as GPU-Z reports maximum clock frequency at only 324mhz. Vram clock is also set only 400mhz max.
Cuda-Z in OSX reports normail values (771mhz for gpu and 800mhz for vram)
Unigine Valley benchmark also reports about half the framerate compared to OSX.
I have Windows installed as MBR/Bios and i was getting an error at boot:
ERROR: Valid MXM Structure not found.
P-State Limited to P10
I have already tried to set Power Management Mode to Prefer Maximum Performance in nVidia Control Panel, with no improvement.

Look for benchmark in the web or the reported performance in the first post.
It is 65% OpenGL performance of HD6790M by Unigine Valley.
K1100M & HD5750 seem to be similar in comparative analysis:
NVIDIA Quadro K1100M vs ATI Radeon HD 5750
Compare NVIDIA Quadro K1100M against ATI Radeon HD 5750 to quickly find out which one is better in terms of technical specs, benchmarks performance and games

From the performance perspective, there is little to no gain in High Sierra. You won't see big improvement by swapping your HD5750 with K1100m, except that you may run Mojave or Catalina smoothly with Metal support by K1100m. However, a WX4130 would be a better investment than the Quadra series if your iMac can POST with it. With OC, you get full hardware acceleration only with AMD GPUs and a BootPicker very similar to the native Boot screen, without the color bit depth issue of Quadra GPUs.
If your purpose is to upgrade to Catalina, I would suggest swap the HD6750 to your iMac 2010 since it has native Boot screen and there is the patched OSX graphic driver coming with Metal support for the HD6x in circulation for testing.

If you have Catalina Loader with the DSDT patch enabled, sound works in UEFI mode beautifully, the problem was that my drive was formatted in APFS, formatted it in MacOS Extended and everything worked right away. This way I have installed Windows 10 1604, everything worked, but don't try to update windows as it contains a incompatible update and it may render your windows unusable. I'll be trying today to install the latest Win10 version. ( Sorry for offtopic )

Hey guys! i know that an GTX 770m, can have a lot of kernel panics into an imac 21' 2011 dues the power supply can't give all the power when that gpu get 90% - 100% use. I aways use my iMac with windows, so im constanstly maneging the power consumption of my stock gpu (HD 6750M) and overclocking it.
I had an idea of undervolting the GTX 770m and put an limit to his core/mem clock to not get at 90% use (wich makes the A1311 power supply work at its limit, wich is the 205w)
Thanks a lot for the support of the community!

It is puzzling to me the time spent by Ausdauersportler replyng to people to follow the original post that could be invested in making sure that it's laid out in a readable manner and cleanup the a maze of dead links to old stuff that never worked in the first place wich would get less questions in the first place
wich would get less questions in the first place
I mourn the death of people's spirit of adventure and the desire to find a solution on their own.
It's funny that you are so quick to attribute this to "a maze of dead links". There are no dead links in the first post. Nada.It is puzzling to me the time spent by Ausdauersportler replyng to people to follow the original post that could be invested in making sure that it's laid out in a readable manner and cleanup the a maze of dead links to old stuff that never worked in the first place
The truth is people do not want to read and even more sad is nobody wants to learn by trying. I have been following this thread for over 250 pages and it is shocking how many people post their questions with never even looking at the first post.
Your guide, linked in the first post, has dead links and is outdated, the catalina loader image link is not downloadable - so that's it, and i also want to make sure you understand, i did my part pointing out the errors in nick's roms wich i had no problem at all fixing myself and just reported back for the sake of information and improvement.
His k2100m vbios has overclocked ram that could cause issues even if the rate of failure would be pretty low and his performance level on the k3100m rom were messed up - wonder what happens to the other roms i did not open.
I was also able to understand once i finally found a working catalina loader image that it is working as a OpenCore chainloader, wich is not pointed out at all. I pointed out the errors on the post but instead of replyng to me, he only bothered to replay when someone confirmed the issues i reported
It is appropriate to write this guide is not about understanding things: it does give you half baked procedures instead of explanations for a lot of stuff, not sure because people that write it does not understand them in the first place. It is a weird hybrid of cargo cult level procedures and "you should understand what you do" answers, with no bridge inbetween.
It's incredibly much easier to do real hackintosh with non apple hw thanks to the dortania guide than to understand how to get OC working here where the work to be done is much smaller but totally undocumented.
Hey - still much better than nothing and thanks for your time, and i see where your pissed out attitude comes from when you give your free time away, but seeing that you regard real contributions on a lower levels than real "has answer in the first post" answers is reeeally strange.

Hi
Herrdude edited his post, wich had broken links, 14 minutes ago
As happened many times before: i complain, people get pissed but actually fix what i told them to. Just too much pride to answer
that's my contribution to the thread i guess: we are still being useful while still acting like *******s.The image on that post does not work on either disk utility or balenaetcher, i downloaded it from an external link that had it decrypted.
If i try to use diskutility to load the encrypted image i get OSStatus22 error . The one i was able to flash and use was a 33mb one.

Hi,
Sorry, I didn't know that.
That said, you've understood the problem, too many illegitimate requests and especially too much information, and then bam, it's you who takes, I admit it's not cool.

It is puzzling to me that guys like you sit in the back the remote switch in the hand doing nothing. There is only one maze of dead links I can think of if I see such a post.It is puzzling to me the time spent by Ausdauersportler replyng to people to follow the original post that could be invested in making sure that it's laid out in a readable manner and cleanup the a maze of dead links to old stuff that never worked in the first place
Just wondering...
