I am not a BIOS modder but you may see whether this will give you directions:
AMD and Nvidia GOP update (No requests, DIY)
I’m not really the guy to run on unlimited supply of patience, so this will be more a mix of tutorial, tool to do the job for you, assistance (“as long as you don’t insist with unlimited/unrelated questions” kind) and ABSOLUTELY NO GUARANTEES. Users should read this again, I am not offering any...

Hi,
I am updating Imac 2011 mid 21.5'. I have a similar GPU: GeForce GTX 670MX 3072Mb, but vendor is MSI.
Сan you tell me what is your result of using this GPU? Maybe you can share a vBios for her (based on dell vBios?)
I installed it physically in may 21,5 iMac =))), that's okay.
and of course I saw a black screen when turned on.. using ssh i saw: macOS Catalina recognizes her as GeForce GTX 670MX 3072Mb, but I do not see any information about display... there is no such section.
Hi everyone!It seems St. Nick is running a few days late this year, 🎅
or maybe a few weeks early, depending on where you live…
Quadro roms attached, for the following cards:
K1000M, K1100M, K2000M, & K2100M
They all have CoreEG2 integrated so no boot-rom mod required.
The clocks should also be unlocked in windows (not P5 limited)
and they have a moderate over-clock which should be stable.
Thanks to @highvoltage12v for running the K2X stability tests,
so if your iMac crashes, for any reason, it’s totally his fault !
I have native brightness control & Target Display Mode working
so far only on the two newer cards (K1100M & K2100M)
At the moment this will require using the OpenCore boot-loader
to do some ACPI injection, and maybe load some additional Kexts.
I’m working on a plug-n-play version that runs from a USB stick,
but there are still some things to fix so that may be a few weeks out.
Not forgetting the red team…
I worked out what was limiting the boost clocks in MacOS,
these Beta3 roms should now be completely un-limited.
I’ve also included an over-clocked version - but be careful,
it will produce a lot more heat so make sure you crank the fans up!
I’m still working on a fix for that code 43 driver issue in Windows,
and hoping we can use OpenCore to work-around the problem,
as it can also be used to enable “iMacPro” HEVC encoding for FCPX etc.
The boot-rom mod is still required for AMD, probably always will be,
It’s included here but there are no changes so no need to re-apply it.
UPDATE for K1100M !
Well this is embarrassing... turns out I'm an idiot!
I accidentally uploaded the wrong file for the K1100M
If you downloaded the previous version do not flash it.
No other cards effected, I have updated the download.
🎅
First of all, thank you so much for all this effort!
If someone could answer some questions would be much appreciated.
I own a Mid2011 21.5" iMac dual-booted running Linux Mint 19.3 and High Sierra.
1. The table displaying all working GPU upgrades shows the "K1100M" and here is the question.
The only thing that does not work out of the box is the brightness control or "the only thing that does not work after VBios flashing is brightness"? I would naturally have the boot menu without having to flash it?
| Quadro K1000M * | ROM | yes (natively) | no | yes/yes/A | no | 35% |
The reason why I am asking it is that I just saw an old post from Linux Mint Community from a member, stating that this GPU worked out of the box with Linux Mint. I use Linux Mint as my primary DAW and mostly use High Sierra for Finale and sometimes Time Warp and Tuning from CUBASE. But I Still need the boot menu to use CUBASE and FINALE on the MAC OS side
Here is the post's linK
https://forums.linuxmint.com/viewtopic.php?f=49&t=297140&p=1653801&hilit=k1100m#p1653801
My last and crucial question:
If this card needs to be flashed in order to work properly under High Sierra. Do you think that it won't work on Linux Anymore?
I am trying to get all my doubts clarified (if possible) before buying the card (it is not easy to find them in Brazil) only at Ebay/US etc
Again, thank you so much for taking the time to read my question ok and I am looking forward to hearing from you"!
Respectfully,
Alexandre Magno. S. Ferreira
To get the boot screen working you have to flash the BIOS linked on page #1.
The card may also work with some Dell Bios versions - but these Dell Bios do not offer a boot screen.
Can't seem to find a definitive answer so after looking for well over an hour now, can anyone tell me if an ATI HD 5750 #109-B97157-00 from a 2010 iMac should work in a 2011 27"?
It's not working for me and I'm not sure if it's the card or compatibility.
It's not working for me and I'm not sure if it's the card or compatibility.
Ok,
Thank you for taking the time
I will read the instructions carefully
But, If I flush the BIOS, will it work for Linux too or Just Mac OS?
This is the wrong thread - but all cards run in all Late 2009 to Mid 2011 system if size fits. Same question came 2 or 3 pages back. We focus on non Apple cards.
Hi all, wanting some help with a late-2009 27" iMac 10,1 (C2D), running 10.13 High Sierra
After picking the iMac up for $125AUD locally with no issues I've found the HD 4670 to understandably lacklustre, and managed to find a GTX 580M, also local pickup for $50. Questions are:
1. Will this card even work in the iMac?
2. If the card does work, what controls will I keep? I've read the info at the start of the thread and found that sometimes brightness controls are lost.
3. Will I be able to use Target Display Mode? This one is pretty important cause I primarily use the iMac as a monitor for my main PC. I couldn't seem to find a straight answer.
If there's anything I've forgotten to read or link, please tell me! I'm pretty new and just trying to find some answers; I'll take any pointers I can get!
Cheers

You need to read the 1st post several times before your action.
In the Important Information, it has already mentioned that you need at least an i3 CPU before you can use the new mac vBIOS for the nVidia GPUs. So, you must change your C2D CPU.
Another point is that your new GPU isn't listed in the nVidia GPU table. So, there is currently no mac vBIOS for your card to get a boot screen that is similar as your old HD 4670. Perhaps with OC, an OC Bootpicker may appear but then it will turn black until the OSX driver is loaded. However, I wonder whether there is any OSX driver support for your card. But the nVidia web drivers can support them up to High Sierra if I recall correctly.
I'm fully aware that the boot screen will not work and I did not expect to find any way for that to work; that's not what I was concerned about. I can't upgrade to an i3 without a logic board swap because of the nature of the different sockets, and I'm fine with the C2D. What I was asking about I had listed in my post.
1, For Bootcamp Windows, perhaps, but not in Mac OS without a mac vBIOS which requires an i3 CPU.
2. The available new mac vBIOS for those listed nVidia GPUs can give a native Boot screen.
3. TDM requires a mac vBIOS.
That information about TDM was the only bit that I needed, I don't know why you keep telling me about the boot screen when I've made it clear that it's irrelevant
Because without a boot screen/ BootPicker, you will find it very difficult to boot into different partitions if you have different OS installed in your disk, and most importantly very difficult to troubleshooting for any issues or problems arising during the procedure. You need the i3 CPU to support the nVidia mac vBIOS (if available) to support the TDM with your iMac 27" as display when running High Sierra only.
And if you have got your HD 4670 working in your iMac 27" 2011 which has already support High Sierra and TDM, and you are using it as a main display for your PC, why spend that dollars to change the GPU and it is irrelevant in making any improvement to the TDM ...

I know that, but I don't need to use other partitions. I'll swap the cards back if I discover some other major issue.
But unless anyone else has some insight on the matter, it looks like I won't get 580M
I saw that 670MX is not in the table of working nvidia cards. I didn't expect that someone will share the correct vBios for mac=). But the Zeitkind had the same card but with the rom(dell?) on which it partially worked.. Presence of such firmware would greatly simplify research.. this is a better starting position than msi vbios from my card (with black screen).
Ok, i will look( try =))) ) for a native dell rom for the card, and try "re base".. and then continue research...
hi guys
im trying to upgrade my iMac. now it just has a ssd drive instead of dvd-rom and 20gb ram ( from 4 slot ).
i want to upgrade cpu from i5 2400m to i7 2600m ( as i found out the TDP on both are 65watt )
so for the GPU side its not easy to find quadro 2100m in local stores here
im wondering can i use GTX780m or maybe GTX870m on 21.5 iMac ( i know there should be some modification for heat sink , but i don't know that it can handle 100watt GPU or not ( i don't have dvd rom and HDD drive ), as i find out from 1st page, maybe GTX770m is a better choice with 75watt TDP but it doesn't support native brightness control ! )
so is it a good decision to go for GTX780m or maybe another gpu ?
thanks in advance

Read the 1st post multiple times to digest all the materials, even those GPUs you are not planning to get, before your action.
Upgrading the CPU from i5 to i7 doesn't increase your iMac's performance much, since you shouldn't do intensive graphic or video editing in your old iMac anyway for productivity reason, despite the increase in CPU cores.
Switching to a Metal compatible GPU would be the priority for improved graphic performance as well as the latest OS compatibility (up to Big Sur).
But of course if you have dollars to spend, consider the M1 MacMini, especially when you are considering the top of the line old nVidia expensive GPUs.
MXM B cards are not recommended in 21.5" iMac because of the power consumption which may make the system unstable, although a few have managed to do so. Power usage of DVD and HDD are relatively low as compared to a GPU on full load. If you read thru the 1st post, you should notice that all the mac vBIOS has limited the TPW to 70-75W within the specification of the iMac instead of their potential max TPW.
Talking about “research“:
Have you even tried to search the net using a bigger search machine than just a few online users here? I get on a regular basis sites as techpowerup.com as a source for video BIOS versions...
No, bad ideas. The i7-2600S has the same TPD but get nearly nothing in return for the daily work.
Stick with a MXM-A card.
Please check out the complete first post before asking the very same questions again and again.
This card didn't age well…Hello! I just completed my iMac 2010 27" upgrade from HD5670 to GTX 860M, now running Mojave 10.14.6 (18G7016) for reasons I'll detail below.
First, I'd like to thank all excellent people who made this possible, especially @dosdude1 @nikey22 @highvoltage12v @Ausdauersportler
I'll outline what I did here, in case anyone has the same setup as me (iMac 11,3 + GTX 860M, but I'd assume any other ++ Kepler cards too). I think it'd help that subgroup of people, because in this thread we're working with so many combinations that at times I had 10 tabs opened and still felt fuzzy about what to do next.
1. Found a refurbished unit of GTX 860M 2GB on eBay. (N15P-GX-B-A2) Upon arrival it really did look pristine. I chose this GTX 860M because I don't want to deal with old cards pulled from a Dell machine. Polaris cards are harder to source and all of them are a hit or a miss. I went with the safest route: new Kepler card.
2. I tried to fit this MXM-B card into my MXM-A heatsink with 2 heat pipes. BAD IDEA folks. It's been warned in post #1. Heed that warning. Unigine Valley will not complete (system froze due to overheat). If you think you won't stress the GPU using benchmarks and might get away with it, still no-no, because 1-hr FaceTime call also froze the system. So I conceded and got the proper MXM-B heatsink with 3 heat pipes in, and glued some tiny copper fins there just for the lulz.
3. The grinding process and ROM installation has been covered several times, so I won't repeat that here. Follow the instructions. For GTX 860M specific walkthrough, read this post by @pappl
4. If all goes well, you'll have a functioning system. Set the fan control using Macs Fan Control. Next, fix the backlight stepping as detailed by @nikey22 on the same post you downloaded his ROM. Tip: when looking up the display ID in SysPref, you'll find "00009CD6" in mmod field. It's "9CD6" part you want. When you try to search the Info.plist, this will match up with "F10T9cd6". I scratched my head for quite a while on this disparity.
5. Assuming you have all the fundamentals done, using High Sierra, try stressing the system with Unigine Valley and Geekbench Compute. If everything is solid, you're good to go. So I did that and uploaded the result to the Google Spreadsheet.
6. Now the fun part: to move your system to either Mojave or Catalina or Big Sur. Advice: back up your fully functional High Sierra with that new shiny card of yours first. I did so using Carbon Copy Cloner.
6.1 For Mojave:
6.1.1 Download @dosdude1 Mojave Patcher, follow the instruction detailed by him. Create a Mojave install disk using the patcher. Then reboot into Mojave installer. Install it.
6.1.2 Once installed, reboot, press Opt, and once again boot Mojave install disk, and select "macOS Post-Install". Select iMac 11,3 and uncheck Legacy Video Card patch. Rebuild caches and reboot.
6.1.3 You might need to press Opt to select your primary system at this point. Don't worry.
6.1.4 Once fully greeted by Mojave, dosdude patcher will automatically launch Patch Updater. Update everything including the fix to allow you to download the supplemental update, install it to bring Mojave to build 18G7016. Patch Updater will ask you to repatch the system, follow that advice.
6.1.5 Reboot into Recovery Partition again, disable SIP, and reboot
6.1.6 Re-fix backlight stepping in the same way as step 4. You'll now have another AppleBacklight.kext. Don't confuse it with the High Sierra version. Then download "10.14.6 2020-003 18G5033 AppleGraphicsControl.kext" from this post. Make sure to not get the Catalina one.
6.1.7 Drag and drop both kexts into Kext Utility and reboot. Everything should be working including native brightness control with proper stepping. All the jazz without using Open Core/Catalina Loader.
I navigated through the lack of GPU Die Temp reading with Bootcamp. Windows 10 will read GPU temp just fine. So I carefully noted how GPU Heatsink temp and GPU Die temp correlate under idle and under repeated stress, i.e. consecutive Unigine Valley. With that correlation in mind (and the confidence that GPU Die isn't roasting itself in there while the heatsink is just chilling out), I set my Macs Fan Control ramp rate accordingly. Done!
6.2 For Catalina
6.2.1 Catalina went off to a bad start for me. I couldn't create a working install disk despite using the very same external hard drive that successfully housed Mojave Install disk. The Catalina Patcher would say that the disk was successfully created, but upon booting into it, I always got prohibitory sign (circle with a slash). This is despite me using gibMacOS to fetch 10.15.7 (19H15) and build the installer from there. Using built-in fetch function of the Patcher failed to start in the same way.
6.2.2 So I just went straight to directly install Catalina over Mojave, by modifying the Post-Install app plist to disable automatic legacy video mod. That went through just fine.
6.2.3 Then I used CatalinaOTAswufix app to update the system to 19H505. Only to realise that brightness adjustment doesn't work. (This is detailed in post #1, before anyone bashes me for not reading)
6.2.4 By updating the system without having a bootable Catalina install disk from 6.2.1, I can't repatch the system too (I have no sound, and probably some more things didn't work), and 0.6.3 Open Core doesn't seem to work with this build… (I could boot it with OC but it didn't bring back brightness control, or GPU temp monitor)
6.2.5 At this point I realised that I've come to a dead end, and also realised that Catalina really does need Open Core to enable brightness control, unlike Mojave which can get away without. All software solutions will still have the display blasting at full power, and generate significant heat. So either I have to have a USB stick plugged in at all times and select macOS every time I turn on the computer, or operate a radiator on my desktop. Neither of which sounds appealing for a machine that I use everyday for everything. It's been my daily driver for 11 years and will continue to be. For my use case, stability and native compatibility are paramount. For this reason, I reverted back to Mojave 10.14.6
The main reason I chose to upgrade the graphics card in the first place is to keep up with new softwares. Most apps are now requiring Mojave or above, including Spark (mail), Lightroom, DaVinci 17, and MS Office, just to name a few. For this reason I'm perfectly happy to stay on Mojave, for now at least.
Hopefully my write up helps someone!
Today I was just browsing the interweb and chatting on IM, suddenly the system froze, then my iMac can't get past the boot screen anymore. Either the refurbished card is kaput, or I foolishly toasted it with the 2-heat-pipe, MXM-A heatsink, before changing to the proper heat sink.
To any newcomers, you're reminded to:
1. Read and reread post #1. Whatever it says, heed it.
2. Be prepared to open your iMac more than a few times. Have your Torx keys ready.
Yes, of course..=) looked at techpowerup.com and quite a few other resources..
techpowerup.com didn't make me happy..=)
the specifications have GTX 670MX and specs for retail boards: MSI (my), CLEVO...no DELL(at this moment I have a question: does it exist?=)) )
situation with the presence of rom is even worse: for GTX 670MX there is nothing..
downloaded for research: GTX 675MX MSI, want to compare with GTX 675MX Mac edition..
elsewhere I found another version GTX 670MX vBios, but again MSI vendor
