Led 1 is on when the screen is connected and it will not boot.
I used the AMD X clamp.

I used the AMD X clamp.
LED1 only means the power is connected. What happened to the LEDs after you press the power button?
I believe there are two types of X-bracket for AMD cards, one for MXM-A card (HD6770M) and one for MXM-B card (HD6970M). The first one is fine but the second one you have to do remove some parts to avoid short circuit.
After pressing the power button led 1 is on. The iMac won't boot with the lcd connected. The X bracket fits perfectly and is insulated, the card works fine with the lcd panel disconnected.
The seller doesn’t send it outside US... 😔
Ok, before I forget
a quick guide on how to install these modern Nvidia drivers for mobile Kepler cards on Windows 10Software needed:
DDU - Display Driver Uninstaller
https://www.guru3d.com/files-details/display-driver-uninstaller-download.html
Nvidia driver 461.40 - Must be DCH version to fit modded .inf file. I used:
https://tr.download.nvidia.com/Windows/461.40/461.40-notebook-win10-64bit-international-dch-whql.exe
Modified .inf file - That is needed to include mobile hardware identifiers removed by Nvidia from modern .inf files.
You can download it from this forum post by StefanG3D (file named R46140.inf). Will need to register to download, I’m not posting it here since it’s not my work.
.inf file is driver version specific, so newer drivers will need a new .inf
https://forums.laptopvideo2go.com/topic/34045-geforce-46140-game-ready-studio-quadro/
Steps:
1 - Extract driver file “461.40-notebook-win10-64bit-international-dch-whql.exe” to a folder (you can use 7zip for this)
Rename R46140.inf as nv_dispi.inf
Inside driver folder, look for "Display.Driver" folder and copy renamed nv_dispi.inf inside (overwrite already existing nv_dispi.inf)
2 - Disconnect from internet (turn off wifi or disconnect ethernet cable)
Reboot windows in safe mode: easy way is hold shift while clicking restart from windows menu, then choose Troubleshoot -> Advanced options -> Start-up Settings. On reboot choose option 4: Safe Mode
While in safe mode, execute DDU. Select GPU / NVIDIA in right column and click on “Clean and restart).
On reboot you’ll have no display driver installed. It is important not to have internet connection, otherwise windows will download and install old Nvidia display drivers.
Reboot once again, this time in “Disable driver signature enforcement” mode. Procedure is the same as rebooting in Safe Mode, but selecting option 7 instead of 4. If in doubt, check here:
https://support.viewsonic.com/en/su...how-to-install-unsigned-drivers-in-windows-10
Open Device Manager, under Display Adapters you should have Microsoft basic display driver. Click on device, change to Driver tab and select “update driver”. Select Search my PC and Select from a list of available drivers. The trick here is to use the “Have Disk” option and navigate to select the nv_dispi.inf we previously copied inside the Display.Driver folder.
If all goes well, you’ll be able to select your card model and start to install drivers. Midway trough install you’ll be warned driver is unsigned and given the chance to install such unsigned driver, choose that and installer should work to the end.
3 - Reboot and check driver version, it should be 461.40. Then you can add registry entries to activate brightness control, just as in old version of drivers.
Notes:
- I have not tested this extensively, it is possible it may not work for you. At first I installed on top of version 425.31, and ended up with a working driver but no brightness control at all (adding registry brightness entries did nothing).
- If you make some mistake, you can always go back to reboot in safe mode and use DDU to remove all display drivers and start over or go back to reinstall 425.31, DDU does a good job at cleaning old install.
- It may happen that future windows updates from Microsoft remove unsigned drivers (to be confirmed).
- Nvidia Control Panel is not working for me.
Otherwise I've been testing this a lot the last few days, modern games like Doom Eternal or RPCS3 work quite decently on my 780M. Also a quick benchmark with these drivers version and @nikey22 780M_BR2 rom
Edit:
I have also now tested this on a Quadro K1100M card and it works too, so this is expected to work for all Kepler based cards, be it GeForce or Quadro.
This time I've directly installed on top of already existing 392.63 Quadro drivers with brightness control registry entry (no DDU, just reboot on “Disable driver signature enforcement” mode and update driver, and it worked ok, with brighness control working out of the box on reboot with the updated drivers).
So, for installs I would first try just installing on top of existing drivers and, if problems like brightness control arise, go the DDU path.
Edit 2:
There's a new utility around to automate newer drivers modding and signing: NVCleanstall
https://www.techpowerup.com/download/techpowerup-nvcleanstall/
I have not tested it yet, but from forum posts it looks that using version 1.7.0 you can add hardware IDs for our cards and get a proper signed driver, avoiding the potential problem of unsigned drivers removal from windows updates (and making installation easier).

Never have I witnessed such commitment to satisfy a curiosity. Congrats on the successful build!
Does anyone anticipate issue with installing the before mentioned geforce driver on quadro cards?Ok, before I forget

Thanks a lot for your response.
Boot ROM is 87.0.0.0.0 (backed up with romtool)
1st Option + Boot gives CL and internal HDDs
Upon Ctrl+Enter CL I come to CL boot choices with CL again and internal HDDs
2nd CL Enter gives black screen with message on top left:

My goal was to switch to Mojave on this machine, not improve video performance
You're right, obviously I hadn't read all of it but this thread is huge Are there people here who manage to use, video aside, this machine permanently on Mojave or Catalina?
Check the first post again:My goal was to switch to Mojave on this machine, not improve video performance
Are there people here who manage to use, video aside, this machine permanently on Mojave or Catalina?
This is all about installing a metal card to use Mojave, Catalina and But Sur. Only a few stick with High Sierra.
Unfortunately in the signatures it is not specified which system is used, not at all.
Anyway, when my machine starts with Mojave (boot from cold machine only) everything seems to work (with Mojave Patcher) except Bluetooth and graphics acceleration ...
Good morning,
I'm now one of you guys!
I've bought a K610M on Aliexpress, and I've installed it yesterday in my 2010 27" iMac.
I had to put a plastic thermal pad on the top of its die as I didn't have a copper plate at that moment. (I'm planing to order some on Aliexpress, but I won't receive them before a month. I hope this trick will work until then).
Afterward, I've flashed the K610M using the ROM linked in the first post (https://forums.macrumors.com/thread....1596614/page-271?post=28497093#post-28497093).
It went mostly well, I got some warning, but in the end, the iMac rebooted and the display was working as expected.
So after that I've checked Macs Fan Controls and I've made sure the GPU would stay cold until I receive the copper plates :
Eventually, I've started the last part of the guide: installing Catalina Loader to fix backlight control and allow the installation of more recent versions of macOS.
First, the latest version (0.6.6) of OC didn't work for me. The OS crashes at boot saying "Failed to load kext com.apple.driver.AppleGraphicsDevicePolicy (error 0xdc008017)".
Second, I've discovered that the version 0.6.0 works well. MacOS is able to boot properly and the backlight control is somehow working. I say somehow because its max level is lower than its regular max level (surprisingly, the backlight control is working perfectly when using TDM).
I've tried different AppleBacklightFixup.kext and none of them seems to work properly. I've also made sure my DisplayID (00009CD7) is in AppleBacklightFixup.kext's Info.plist.
Do I have to reset PRAM every time I change this kext?
Does someone has a solution?

Edit2:
After some testing, I can confirm this also works for Quadro cards (tested on K1100M, but expected to work on all Kepler based ones). I also checked some games require version 440+ of drivers, so only way seems to update them with this method.

First post, how to install Mojave.Unfortunately in the signatures it is not specified which system is used, not at all.

boot-chime loop without GPU installed?
In that case something else is broken in your machine - no idea what might be the cause, and no idea how to find out.
You flashed the file named "Dell RX 560 2GB.rom" to your card?
Using that VBIOS UEFI booted Windows 10 worked fine on my machine. Do you boot into Windows 10 using Bootcamp or EFI?
I didn't test anything else and don't have that card installed currently. Windows 10 is not that important on this thread.
Yes, that's all completely normal - it's just that you don't understand yet how Catalina Loader and/or OpenCore work.
The only thing that matters now is that your Mac automatically launches OpenCore when powering it on, without holding the option key.
In case it does so, that's all you need in order to test whether your WX4130 is actually working.
Hi. I've successfully installed these cards with your firmware on two different iMacs, but noticed that neither is able to send video to an external display using mini-displayport. Any way to fix this? Thank you
First post -> black screen issue. But you should be able to force the internal LCD to switch on by holding alt/option on boot. Another symptom, same cause.
Very fast reply! But the internal screen works. Only external ones, via mini displayport, don't. I suspect it's an issue with the vrom?
I wrote different symptom, same root cause. But you may ignore my post ...
BTW: add a signature and describe system, macOS version, card, etc...
Hi,
i have been able to flash Bios for K3100M_BFR via usb linux and now I am stuck with that issue in video below.
I know that I need to install a modified kext, but how I do that with the black screen? I hold ALT when reboot but the monitor stays black like the video? can I install macOS in a usb and flash that kext in usb and then in IMAC?
Or exists a way to remotely install the package remotely?via ssh or something?like I did to install bios?

Just to update. I managed to find out the cause. It have something to do with the thunderbolt to usb 3 adapter I plugged into the iMac. Brand is kantex ktu20. Once I removed it, display works. Windows doesn't seems to talk to the thunderbolt 2 ports properly. If anyone have suggestions, I will try. Thanks.
