iM 4,1-14,4 2011 iMac Graphics Card Upgrade

[arctictropic]

First i just want to say that this thread is amazing and Ive been following it for a while!
I have a odd question; i just recently repurposed and refurbed my 2011 21.5inch imac as a Win10 pc for my son...

Its cleanly installed, not bootcamped as win 10 with no mac partitions at all. Its installed in legacy so everything is recognized and working (incl my Radeon vid card).

Now to my question, if im ONLY going to run win10, boot straight into it is it known if the constraints for cardselection still apply? Obviously W10 has native drivers for everything but first it still needs to be recognized in bios during boot...

Basically, any chance a more modern Nvidia card may work for my scenario?
Cheers

The following is a vbios ROM for: Nvidia Quadro K610M

K610M:
MXM-A (3.0) bus interface, low powered card at TDP 30W.
It is a drop-in fit for the 21.5" iMac and 27” iMac heatsinks.
It is based on the GK208 GPU Kepler 2.0 architecture.
Metal supported.

I put this together only because there are now a few members on here that have one and it is relatively cheap to purchase for the moment.
It is based on Nick [D]vB's ROMs. All credit to him.
I have not had a chance to test it fully, but I can confirm brightness control will work with Opencore implementation on High Sierra 10.13.6.
Bootpicker menu is also available ofcourse.

This card should be added to our database of working GPUs.
Enjoy.

As promised I'm reporting back my experience so far with the K610M and this vbios. I have installed the card without problems, only very slight modifications were necessary (had to rise the x-clamp slightly). I disconnected the hdd, plugged in the usb with the linux tool (tested before on other mac), tunneled in via SSH, flashed per instructions, all went well, no issues.
However, after reboot, I am greeted with a black screen and nothing else. I do have image via external (DP to HDMI) and can see the vbios is correctly flashed according to about this mac. Temps are very low and the Mac is otherwise working fine. Checked connectors and these are certainly OK. This is a test mac and was working fine before so I can exclude the lcd, inverter, etc as possible causes. It's a 27" 2011 imac with the 3.4GHz i7.
On the HDD, which it is booted off now, there's a Sierra install, version 10.12.2.
Unless I misunderstood something, the opencore bootloader is to gain native brightness control and is not necessary to display image on the internal display, so right now I don't know what could be causing this. Should I reflash even tho everything indicates the flashing was successful? Or is this a known problem?
Any help appreciated!

EDIT: if I can't find any solution, I will put the old GPU back to verify the iMac is in fact still working correctly so I can exclude the other parts with 100% certainty, and work from there. The X-clamp is making contact with the motherboard because it's slightly raised, but I put electrical tape there to be sure there's no shorts. I also was very careful with checking I did not hit any small components on the motherboard with the X-clamp.

Did I ever mention the first post on the first page, bevore? I did not use Sierra for a very long time but I remember a remark on this very first post talking about black screens with Sierra...hope this helps.

And yes, you need the latest and greatest firmware on your iMac to run OpenCore (87.0.0.0.0). If it is a known problem than using the "search" could be the other way to get the info...

What do the diagnostic leds say?

 

[NOTNlCE]

If it's usefull. The MXM power voltages / distribution is derived as follows.

Also attached is the overall power scheme for the Main Logic Board. There are (max) Amperes mentioned for the MXM voltages, but as described the current limitations are collective - the are no specific power limitations for the MXM only voltages.

Very good to know. After reviewing the two schematics all day, I am not sure we will find too much else without testing voltages firsthand. I am eager to see what changes across various voltage points between a "good" card and a "bad" card in a 2011. One thing I did notice was that the current sense circuit for SMC_GPU_ISENSE is a bit different from the 2010 circuit. I think the key items we need to determine are:

• Is the MXM card getting power? And I mean all its rails, not just the 12V from the PSU...
• If yes, why is it not detected?
• If no, why is it not getting power?

Unfortunately, the MXM_GOOD signal comes from the PCH, not the SMC where the current sense goes... But the MXM_GOOD signal also illuminates a diagnostic LED, so eliminating the PCH as an issue may be easy. I have not personally checked out a "bad" card in a 2011 for more than a few minutes when I tested my WX4130...

Such an odd problem! Perhaps I may have some time this weekend to take the WX4130 out of the 2010 and break a 2011 open again for testing...

EDIT: Interesting, the GPU must be getting power if the machine POSTS, since the S0 rails would be required for the machine to turn on... I have not read enough about the spec to determine what is required for a "detection" in the system, but based on how much power the 6970M sucked, I doubt the current sense is too high for the SMC, especially on the WX4130 and lower powered cards.

Hello all and thanks to all of you for the super informative details in this thread. After reading the first post and many of the others, I have been convinced to try to restore my mid-2011 27" iMac after the GPU (HD 6970) failed. I have found and purchased a used Radeon Pro WX 7100 mobile video card pulled from a Dell Precision 7720 laptop (the card is the 109-C95847-00D_02 version with Ellesmere written on the board assuming I get the card shown in the picture online). I have also purchased the necessary CH341A Programmer and components to flash the bios on the card.

Request some backup to ensure I am reading the information on these posts and the PDF attachment describing the differences with the cards that have been tested so far. Specifically:
- For the WX 7100 I think the only thing that is needed for the card to drive the iMac's display is the BIOS flash using Nick's BIOS. Although I may jump into the OC aspects later, I am initially only concerned about getting the display to be functional again.
- The iMac currently has High Sierra installed but it has not been updated in nearly a year so it shouldn't be subject to the May 2020 black screen on boot issue described in the first post.
- Although I have the proper heat sink (3 pipe) which should not need to be modified since I am getting an AMD card, I still might need to either modify my Apple X-Clamp or use the technique shown by "tgaillar" in his 26 Feb 2020 post to ensure I don't fry the card.

Are the items above correct? Is there something else important I am missing? (aside from the data backup and BIOS backup steps that should be done before starting...)

And my final question is about the power draw of the WX 7100. The AMD site lists TBP (Total Board Power) as 100W and this should represent the power required to be supplied by the iMac power supply. TechPowerUp lists TDP (Thermal Design Power) as 130W indicating the amount of cooling required to be provided by the system. I am curious what those of you running systems with the WX 7100 are seeing for the actual power draw and for your GPU temperatures? And what speed you are running your GPU fans?

Thanks again for the great forum and for any help you can provide a forum newbie.

Hi,

In a few words: you have a correct understanding.

In a few more lines:

- the correctly flashed card alone (no OC), should show picture after HS successful boot (you will not see the Apple logo and the loading of the macOS)

- in relation to the HS version - bootrom is supposed to be updated to 87.0.0.0.0. If you did run a regular security update last year when the computer was still functional the chance you will have this is high. Anyway, a black screen issue would be the least if you get the computer to boot with the card first.

- Correct, but still carefully inspect the card and make sure no SMD parts are touching the heatsink. Especially the coils in the upper corners. Also, make sure you properly seat the card into the slot. And attempt to boot first with as fewest components attached as possible.

- Recently somehow we got to a conclusion that the power on its own should not be a problem, but this is not entirely confirmed. On the other hand cooling of the card under load might become a problem. Ensuring the gpu die sits flush with the copper plate and thermal paste work is done well, you should be able to crank up the ODD fan and keep the card within working temperatures. You should also get backlight/brightness control which will help with the overall system temps and cooling. I keep the ODD fan with WX4170 under load at 1800rpm, when "idle" (read no GPU intensive workload) there is no problem whatsoever and ODD fan is at minimum values 1150-1200.

- If you still can start the iMac - do an NVRAM reset and shut down before you attempt the replacement.

Having said that... If you get the boot chime once WX7100 is in, you have gone a lot further then most in the recent 4-5 months, and I think several folks around including me will be happy to help to get the other things going from there. At the moment successful POST seems to be the place where most of us are stuck at.

To avoid Black Screen after May 2011 update for High Sierra and using OpenCore with AMD card, there is a solution that works for me.

Replacing AppleGraphicsControl.kext was not enough on my AMD card, i had to block AppleGraphicsDevicePolicy kernel extension too in OpenCore kernel section. (This parameter is checked originally in Catalina Loader AMD config.plist)

As i was on it, i patched too AppleGraphicsControl.kext for Mojave 10.14.6 and Catalina 10.15.5 injecting our iMacs IDs as HighVoltage12v did before, they maybe not mandatory, just in case.

Hi! You are absolutely right, I missed that part on the first page about the black screen. I have added the board ID in the plist. After reboot I got image on the lcd albeit in very low resolution, but I think because the external monitor is the main monitor and that's a 1366x768 monitor. But before I could go to system preferences the iMac shut off and haven't been able to turn it back on. It seems like the PSU gave up, which is strange since this card is not very power hungry, but maybe just bad luck. I'll open it up when I have the time and check the diagnostic leds and if necessary replace the psu.

 

[Ausdauersportler]

Sorry for my late reply,

I managed to lock me out of Catalina quite effectively. Got the idea that performance could be better without OC due to potential Kext redundancies - guys, never pull off the OC Stick without adjusting Startup disk before...
I ended up booting in Kubuntu endlessly, still do not completely understand the mess, mayby Kubuntu tried to be helpfulistalling hybrid mbr or messing aryound with fw. No chance using Option Key blindly, disconnecting internal disks and plugging them in after booting OC, messing around with OC EFI Shell, refind.conf etc.

Took me several days to figure out to:
1. Create Catalina Installer again via dosdude Patcher on externel TB SSD
2. Change EFI Boot Order from within Linux with: efibootmgr -c -d /dev/sde -p 2 -L "Catalina Install" -l "\System\Library\CoreServices\boot.efi"
3. Change Next Boot Efivar by: efibootmgr -n 2
4. sudo reboot
5. wait considerably for Catalina installer to load
6. Set Startup Disk to Catalina Loader (OC) again

Maybe this saves someone some headache...

I can confirm now, that thermal limits were only an issue under linux in my case, as the mbpfan service does not support listening to GPU heatsink readings, so ODD fan being stuck at min RPM, leading to thermal issues under linux. Anyway, the GPU clock went up to nearly 1200 MHz.

Under Catalina , I have Macs Fan Control installed since SSD Upgrade (config as suggested by Pascal), no thermal issues- Temp barely reaches 50°C.

Unfortunately my performance problems are still not resolved, as GPU clock is stuck at 300MHz in Catalina.
Any ideas?

roscho

Hi!

We were observing the same lock to the base core frequency of our WX7100 and WX4170 after system sleep. We could solve the problem by adding this two lines to the OC->DeviceProperties section (in fact only the first one is probably needed).

Adding this two lines brought me the same valley performance before and after sleep, only limited by the vBIOS settings.

Key*	Value	Type
PP,PP_EnableLoadFalconSmcFirmware	1	NUMBER
PP,PP_WorkLoadPolicyMask	4	NUMBER

The same goal can be achieved by adding the attached extension to the OC->Kernel section and reboot, too.

The extension was boiled down by @Pascal Baillargeau from the original RadeonBoost...

Hope this helps with your "slow" but working WX7100 (using the WX7100_GOP.ROM, I guess).

PS:
I managed once you "pulling SD card disaster" just by replugging and and pressing both alt/option + T on boot. For unknown reasons the system began to search all external attached boot devices and booted finally from the only available SD card. The same works with USB devices, managed to boot off my Linux flash stick that way.

Maybe somebody could confirm this option T thing??

Hi, to add to the recent discussion of power draw on AMD card's in 2011 iMacs, I wanted to add that my non-working 00D WX7100 was drawing 12V @ 0.71 Amps according to iStat Menus. The temperature of the GPU Heatsink sensor also slowly converged towards a steady state which was not very high. It all seemed pretty healthy.

Although I did not do any measurements on the MXM socket itself, maybe this helps. In a few weeks a replacement 00C card will arrive from my vendor and I will report back.

 

[stephengrenfell]

Unfortunately, the MXM_GOOD signal comes from the PCH

Yep MXM_GOOD signal is driven by GPIO 35 of the PCH, I suspect the CPU is driving this when it's happy there's a GPU

Otherwise if it's usefull:

The PM_MXM_PGOOD signal from the MXM connector is ANDed with other power good signals to create the ALL_SYS_PWRGD_R signal which drives 2nd diagnostic LED (ALL_SYS_PWRGD Led) and DDRSYS_EN signal.​

​

The PM_MXM_EN signal to the MXM connector is driven by the AND of various CPU voltage good signals and the PM_PGOOD_PVCORE_CPU signal from the CPUs ISL6364 power management IC.​

​

The MXM_DETECT_L and MXM_DETECT_R signals are not used; they are only connected to 100K pull up resistors to 3.3volts.​

​

All the PCI-E bus connections from the MXM connector go only to the Sandy Bridge via decoupling capacitors. probably not relaver tout for completeness.​

 

[bokkow]

I feel a bit like a broken record now but; anyone tried installing the supplemental 10.15.5 update?
Tried downloading the separate package but it (obviously) says it is not supported.
The only way would really be a full install download through Dosdude's patcher?

Yes, using dosdude1 latest patcher. Both my systems updated without problems. I did not have black screen or other display issues (apart from sleep). Sleep kexts installation has to be repeated once installation is done. I have not lost any data or settings. Catalina on unsupported mac thread has other methods but hands down to @dosdude1 his method in my eyes is the best.

I can only boot to a white after I reset the PRAM. Otherwise the screen is black. Any ideas?

However, I don't need it for Mojave 10.14.6 at all, on that very same machine.

Hello Everyone,

I’m new in the forum and will be helpful for any help.

I’ve got an iMac 2011 27” with an i5 core. I want to do some upgrade to it bc my wife needs a new one with more power.
the seller told me that sometimes the graphics are a bit squischy so I decided I’m going to replace that.

mal what I want do to:

switch the i5 to an i7 2700k or Xeon E3-1270/1280 after I updated the EFI to 1.9 - if needed (bc the seller told me he never done it)

secondly I’m going to swap the graphics card. Currently installed is the HD 6970M with 1 GB VRAM. And here I really need your help.
I did some digging and find out you could use and GTX but just with some missing parts so I’m going to swap in a AMD one, but here is the question: I could Buy an AMD R9 M290X (HD8970M) with an P370SM vBios and here I need your information and help, the seller of this card told me that he doesn’t know if this will work and I can’t find any information about it or about this card in combination of an iMac 2011 27” And MacOS at all besides the Hackintosh forums.

So I hope that someone could ask my question: will my Upgrades work and most importantly will the Graphics card work ?

Kind regards,

Of secret guide to all this is on the first page within the very first post of this thread. There you will find all the known to work cards. Of course you are welcome to buy and test different cards, please come back with your experience and share it

Before you change the CPU please check carefully online what is known to work. Sometimes you will loose sleep functionality.. from my own experiences there is really no difference between i5-2400, i5-2500S, and i7-2600 in real live. Only the well know benchmarks produce different numbers. The TPD of the CPU should no exceed 90W - this is the design limit.

Thanks a lot for you answer, I reed carefully about the TDP and with the 1270 for example I would have 80 and with the 2700k I will have the same like the i5. So not more.

the card is a other story and I k ow the first page that’s why I registered here bc I feel that here is a lot of knowledge to find.
So I assume that no one tried out this card so far?

i could buy this one but it’s 140euro so I have to think about it in the first place.

kind regards,
