sorry, i didn't get your point.
this card runs irrespective of nvidia webdrivers.
the issue is about card not reporting its die temp.

This issue is known since 2014, it has been documented, it is one of the seven problems listed, there will be approximately 1000 posts similar like yours. And even more people just missed or ignored the documentation about this complete topic after the got a card from elsewhere.
And again: AFAIK Kepler cards are supported by Apple on (High) Sierra (starting with 10.6.8?) , drivers got finally removed on one Monterey update this year. You do not need to use web drivers!

Edit:
And it has been resolved...

The sound issue with UEFI Windows 10 is resolved by OpenCore (SSDT patch) and it does not depend on the dGPU you are using. In fact I am moving a single (UEFI Windows 10) SSD around between all my systems.

If your sound is broken check which hardware is selected in system prefs. EFI capable systems can of course still use legacy installations, but why would you do this when recent Windows packages do not fit any longer on a DVD and you have to use OpenCore for macOS anyway?

Thank you for responding @Ausdauersportler. Can you please clarify whether this SSDT patch is part of OCLP 0.5.X, or is something I have have to do separately? I am admittedly confused surrounding this patch though trying to find more details. Could you point me to where I can find out how to patch it - if it is indeed separate? Not to digress from the hardware thread but my install on the separate SSD was not via bootcamp assist - could that be an issue? The reason I was going to try a DVD(MBR) install was to overcome this issue but the UEFI method is obviously preferable.

This file is has been included for at least 18 months now into OCLP and it will be activated if you download and run OCLP own your iMac12,x and build and install OpenCore for this target machine.

UEFI installations work only when boot through OpenCore. AFAIK it needs to be an internal target disk, later you may be able to boot from the same disk externally connected. Honestly my Windows 10 experiences are really limited. But I can tell at least this: Sound works fine with OpenCore + UEFI Windows.

You always need the so called BootCamp drivers to enable the Apple hardware like BT, sound, keyboard etc. - use the GitHub tool brigadier to fetch it from apple.

The OCLP docs contain a short guide about how to install UEFI Windows on the iMac12,x and how to get around the black screen issue when Windows loads the not working HD3000 drivers.
 
@Ausdauersportler thanks for the heads-up and your experience. I won't side-track the hardware orientated thread any further - but I'll leave with that I tried the OCLP Troubleshooting link (preventing the devIDs under windows 10) and encountered the same delay followed by the dreaded BSOD. AFAIK now there is no present solution for these select few Kepler graphics cards according to @m0bil.

oh, gee, sorry, got it thanks, just was busy with K4000 installation that never succeeded. never made it to the last problem.

btw. how did you get your gpu die show temperature ?

You have to survive a boot delay, yes! You may search the thread, sure the author of the first vBIOS versions commented on this. This is not a real problem - more a cosmetic one - and therefore you cannot expect a solution.

Since I am maintaining the docs you may take a look at it. Another purely cosmetic issue, there will be no solution for such face lifting issues other than using some third party tools if you need to look are a temp reading once in a while. This particular reading was provided by the software. But it is a nasty hack, I try to avoid Macs Fan Control.

But there is a nice and simple one for the ODD control.

hi , I just upgraded my iMac 27" 2011 mid and would have the OpenCore EFI file for IMAC 12,2 and the Monterey installer on a USB stick , Must say my iMac works now perfect with Montery , have upgraded to 32 GB and 2T SSD . I only lost the internal speaker , which is not a big problem since the earphone plug works .

Install OCLP 0.4.11 or 0.5.1 - both versions should provide sound support. There is simply a bug in the latest version. Please post your Monterey experiences in future using this thread.

Has anyone (except the usual suspects) noticed that Target Display Mode is back with Monterey?

Just connected two iMacs with a Thunderbolt 2 cable and triggered a connection with CMD+F2. Source was an iMac12,2 with RX5500XT and target another iMac12,2 with WX4170 - both EG2 EFI vBIOS.

- starting the session with CMD+F2 on WX4170 iMac
- no sound output on target system, although target was listed as iMac in system prefs sound
- brightness control from source keyboard on target system worked (small time delay, though)
- finishing the session needed the same command, but on the target the screen went black (backlight off)
- temporarily connected an external display to the target machine, the sync process triggered the backlight on, again.

Could repeat the process several times before the target ignored new requests.

In case you have older iMacs (2009-2010 with display port connection) or more recent hardware (thunderbolt 3) can you test this with your iMacs and MacBooks and report back? In any case you need the correct cable! The target system decides, so iMac 2011 with TB2 ports needs a TB2 cable, iMac 2010 with miniDP ports needs a miniDP cable. You cannot mix and match as you like.

Same rules will possibly apply to more recent iMac hardware.

Tested TDM with 2 11.3 iMacs latest Monterey, one with a M6100 the other a W6170M and 2 different mini display cables (to be sure). TDM is not working. Screens go black for a half a second. Tested each way.

Check the first post, TDM on miniDP is working using a different method. But you might need an EFI vBIOS and some patience while sending the CMD+F2 - meanwhile my iMac12,2 does not want to sync, but it is my main workhorse and I am not willing to reboot right now.

Found it. Thanks. I'll stick to LCD Driver boards for orphaned displays:). 3 working so far, power consumption 40 watts.
 
Hi guys - I have a NVidia K2000M card, I've removed the existing card from my machine. the new card has the x-bracket with the smaller screw holes and rivets. Can I remove the x-bracket, I applied firm pressure with a screw driver, alternating each hole - is this the way to go. Obviously don't want to mess up the new card.

I saw a guy using a hair dryer to loosen the glue with a similar card just not sure if this is applicable here?

Thanks!

Hair dryer will be fine, before you re-invent all wheels just read the documentation on the very first post of this thread.
 
Help needed !

I recently updated to 12.6.1 through opencore and was working fine, I noticed and small update for that was not the Ventura update and went ahead and updated through OTA ( Big Mistake) the imac was fine for most of the day i did not rebuild opencore then i noticed that the wifi disappeared so i thought to be a glich reset the machine. Since then the imac is in a boot loop and internal screen wont turn on doesnt matter how many attemps through rest, SMC or PRAM. I really want to avoid taking the machine apart again if i can.

The update was for some video formats ect im worried that the update has written over the drivers for the screen.

I have also tried to boot from opencore on memory stick either doesnt start up or goes to boot loop.

11,3
Gtx880m

Any help will be appreciated
 
Just flashed my card which I purchased second hand as an Nvidia K2000M, during the flash process the nvflash utility complained of a hardware mis-match - suggesting the hardware was in fact a K1000M. I tried this rom and it successfully flashed.

Have I been mis-sold an inferior card? I took a quick look at some benchmark comparisons but not being a pro with GPUs I couldn't see a huge difference, although 2000 sounds a lot better than 1000 to the novice that I am.

I'm not a gamer, mostly desktop applications and the odd YT video is all I need.

Thanks in advance.
 
I just ordered a Quadro K3100m few days ago. I placed it in my lovely iMac 27 2011 and.... nothing. No boot chime. Just the fans spin, only first diagnostic led lights and then shuts down. Its a gpu from a dell machine. Did something wrong? Faulty GPU? Before I swap the gpu iMac has on it an K1100m. Everything was working fine. I just wanted little more power with K3100m. So what should be.

P.s Sorry for my English. Im from Greece.
 
Kalimera!

Check the known issues tab in the NVIDIA spoiler of the first post. You have likely an SMBUS conflict. Follow the instructions made there.

You should have read this post before starting your installation process…

My 12.1, mid 2011 21.5 inch, with Xeon and K2100M GPU is currentluy perfectly running with Monterey, what about installng Opencore Ventura, since the GPU support Metal until 1v4, did somebody already try Ventura on this hackintosh model?

Slightly off topic here. Still unsupported from the OCLP team as of now and you may find more information on this thread. I have added some notes on the first post, you may read them.

Hi, I have an iMac 27 (iMac11,1) MacOS 12.6.1 with AMD W6170M installed.
I would like a more powerful card, which one is better to take W3200/WX4130/WX4150
I do not consider WX7100, very high price (it is better to sell iMac)
More for games, well, installation at the initial level.
I use the OpenCore boot screen, have you seen posts here with iMac board firmware to return the boot screen with these cards will it work? Or these cards need a special vBIOS.
sorry for my English

(Metal) performance of W6170M is really essentially on par with WX4130/WX4150. More powerful cards would be (in roughly that order) WX4170, W7170M, S7100X, RX480 and WX7100. Everything regarding the EFI boot screen with these cards is already linked to from the 1st post. (You will need this add-on to actually see the EFI boot screen with M6100, W6170M, W7170M or S7100X…)

Hi all. I ran into a problem when updating iMac 21 2011 to BIG SUR, during installation, the sound in the built-in speakers disappears and the headphone output is shown, although nothing is inserted in the slot, if I roll back to high siera, the problem disappears. How can this be fixed
