iM 4,1-14,4 iMac 2011 Maxwell and Pascal GPU upgrade

Status

Hello, the other day I bought the M4000M from a DELL laptop (before buying it, I checked it and flashed the BIOS (bios 2) on the same laptop) Then I came home and started installing it in my iMac 27 (2009)
And I have such a problem: the drivers are installed but in the device manager Error 43. Direct me, what am I doing wrong?
Installed drivers via NVCleanstall_1.13.0 without results.😢

What vbios came the card with? I took a look at the ones in Techpowerup and certainly display outputs are very different to M4000M, does not look like they would work with either internal or external display.
Also GPIO assignments are very different, most probably because of different card design.

Will take a look at moving either M3000M or M4000M display configuration to the M2000M vbios and see how it goes.

It should be the one here. It has the same subsystem ID and it was supposedly from a Dell 7510. The m2000m vbios may be set up for switchable graphics where the m4000m may have dedicated output?

I also found this pdf online, it's Nvidia's requirements for an mxm module. According to this they should all have the same pinout (page 40/41, which makes sense), but could have different display support which sounds like the issue (page 15). Seems like the display outputs would just have to be programmed to match the m4000m maybe?

Did you take the steps from Santa's post here? They are important to run correctly.

Open core cd now gives me boot picker!!! (THANK YOU!)

Ok… the only thing I’m missing is external monitor support.

My external thunder bolt display doesn’t operate in windows with either th port.

I also tried just using mini display port to regular display port cable for my asus pro art monitor. No dice.

I remember windows doesn’t like external monitors on an iMac especially thunderbolt flavored. This is basically the last functionality I’m looking for, if it doesn’t happen though life is good.

Also… if I’m skipping Mac OS, should I make a partition for open core on the windows drive? Otherwise I’m booting from cd all the time. I have sd cards too….

I do get sound from the thunderbolt monitor…

Download DiskGenius and copy the efi folder of the opencore CD to the EFI of the windows drive.

Never tried thunderbolt, so can't really help here, but mini display port (the one closest to the usb ports) should work.
Make sure the monitor is connected when you boot the iMac, otherwise is may not be recognized on hot-plug.

Should I use OpenCore to boot Windows? Or do I need to install Windows UEFI?
Click to expand...
Are you running Windows in legacy mode? That could possibly cause the code 43 issue. I had one vBIOS that ran in MBR but caused code 43 in UEFI. You could have the opposite issue... Is the laptop running UEFI windows? I believe to run UEFI windows it's recommended to use opencore for the audio fix.
 
Really loving the new system! Its absolutely perfect for my needs! Its a great AIO that will work for my boys.

Now its time to upgrade my spare parts mac!

I have the i5 so I will probably throw a xeon in.

I found a really great price on a questionable p4000 I can return if it doesn't work out.

Also considering trying my hand at vbios modding and going for a p5000, p4200 or another untested card.

Or just grabbing another 1070... The p4000 though is so close and the higher tdp card is unbenchmarked I think?

I'd go for the P4000 if you can refund it in case it's bad. It's an already tested card and I have some untested overclock mods that should make it perform close to the 1070 (expecting around 5000 score on Time Spy vs 5600 on the 1070), and at this high gpu performance it's the cpu that starts to bottleneck the system anyway.

As for untested cards, p5000 should work with same modding as p3000/p4000, but p4200 and other "newer" cards have something different on vbios tables that make them not work in iMac with same kind of modding (I've been unsuccessfully testing this it on a P2000 with @jay508)

So p5000 might work with p4000 rom?
 
Hello, I recently wrote about the unsuccessful installation of the M4000M in the iMac 27 2009.
Before buying the video card was in the laptop, I immediately updated the BIOS from 84.04.9В.00.15 to DE.AD.00.BE.EF
In MacOS, nVidia Driver didn’t even open, and in the system report it was written about a 22MB video card and there was no video acceleration (the system interface was terribly slow)
After I installed Windows 10 (installed from iMac and even took already installed from HP laptop)
But after installing the driver, the video card turned off with error 43.
After that, I flashed back the BIOS 84.04.9B.00.15 for the DELL laptop and returned it to the seller, he installed it in his laptop and said: that the card forcibly shuts down the system after downloading and installing the drivers. He says that I broke the card and the fault is completely mine.
_________
Although I just installed the bios and put the card in the iMac after processing the cooling.
Tell me what could be the problem.
Thank you for your attention.

The seller was right.
Hacking vBIOS is absolutely out of warranty coverage of any manufacturer.
And no seller will confirm that a Quadro M4000m will work on any iMac.

I did have to assure the seller of my Quadro M4000m that I would not return the card when I told him that I would use the M4000m on my iMac.
I just needed him to warrant that he had test the card on his Window system thoroughly.

It seems you flashed card right. Nobody has tried before this card on a 2009 iMac, so that may be the problem. If it is a late 2009 core2 duo there have been known problems with Nvidia cards making them not work on such systems.
 
Just an update... m0bil has been working extremely hard to get the m2000m working on these imacs and... WE HAVE EXTERNAL DISPLAY! The card is running at full clock speeds as well, no P-state issues like the m3000m/m4000m had. I currently have it installed into a 21.5" 2011. This is a great card for the smaller mxm-a heatsink. Going to do some benchmarking for temps while m0bil continues to work on internal display.

Here's a teaser:

sorry for stupid question, but to boot windows 10 should i use opencore bootloader?
Click to expand...
It is highly recommended but not required. In UEFI mode the internal speakers will not work without opencore, and you may also need it to use brightness patches depending on which gpu you are running. It will also enable boot screen if you ever want to dual boot or boot from USB/DVD/SD card.
