The fans ran like crazy during the Valley benchmark. But, it runs Catalina with all the other metal aware apps unlike the 4670M. For writing, surfing, programming etc. this card is more than enough.Oh, it's compareable with ATI HD4670M

Read post one on page one of this thread!First of all apologies if this has already been asked. I upgraded the video card in my iMac Mid 2011 on Tuesday, flashed the BIOS to Nick[D]vB's custom firmware. All worked well in High Sierra, my external display was correctly detected.
I then added the OpenCore USB boot solution and got native brightness control.
So I took the plunge and installed Catalina using the DOSDude utility. I am now typing this from Catalina and everything is working except my external display is no longer detected.
I am hoping there is a quick and easy fix for this?

I'll never really understand why it's always assumed that you haven't read the first post. The fact that I got this far should imply otherwise. I know one thing, I never want to go through dismantling another 21.5" iMac again. Good old Apple and their screws on the back of the logic board =). Anyway I decided to try switching the adapter I was using. My secondary display was connected with a Mini-DP to VGA adapter. I switched to Mini-DP to DVI and it worked.

Could be a non standard apple Keyboard? See if just holding the letter T brings up the target disk mode screen. Also check for a capslock light
Random shutdowns are highly unlikely a MacOS problem. Because of the encapsulation of user land apps I cannot imagine in these days of an app causing a random shutdown. You may have bad installer fiies or an hardware issue. Reinstall MacOS on a separat partition using freshly installed USB installers (probably a new stick) and check this on your own.
thx. so a suc6 story after all.Reporting a working WX7100 installed in a 27" iMac mid-2011. I've been craving one for a while, so happy it worked. I purchased the card from the same vendor as @wa9im and was pleased to get it quickly (China to US in 11 days). VBios was installed with a CH341a clip using the @Nick [D]vB WX7100_GOP.ROM file, then traded out a K2100M for it using a 3 pipe heatsink. It is being booted with OpenCore (AMD config), to a previously installed DosDude Mojave; I still need to work out sleep which had been working with the K2100M (Something to do tomorrow).
Just wanted to provide the details and to offer my thanks to @wa9im, @Pascal Baillargeau, @Nick [D]vB, @Ausdauersportler, @Emilio306 and @jborko for blazing the trail and contributing to making this a success.
UPDATE: The sleep problem was within OpenCore; went to native Mojave boot, and sleep is now working again. Since OpenCore is not needed for brightness controls, I suppose I don't need it, unless I want to add alternate OS in future and have a selection at boot.
On the last photo ( Graphics.png ), the parameter "Automatically Adjust Brightness" is "No".Reporting a working WX7100 installed in a 27" iMac mid-2011.

What are you asking for? The brightness controls? It is there natively with the AMD BIOS supplied by @Nick [D]vB and @internetzel without OpenCore. You need the OpenCore for other things described in the first post and the linked docs. I will not copy and paste here...On the last photo ( Graphics.png ), the parameter "Automatically Adjust Brightness" is "No".
How are things in reality ?
You had the Mac Fan Control (or a similar App) running all the time you used the K2100M?So today my Quadro k2100m officially died, literally ran a benchmark this morning and everything was perfect FPS wise in Valley, was loading up Logic Pro and my display went nuts and then blank, it had been in my computer for 2 months with zero issues until I lost external display last week, put back in the radeon HD and it was working! So looks like my card was faulty from the getgo, or on the road to failure, it's a shame so many of these cards seem to go bad, or just these MXM cards in general.
Thanks again for all your help, it wasn't in vain.
I'm interested in something else.It is there natively with the AMD BIOS supplied...

Yes, just cross checked with a K4100M/K610M/WX4170: You can have the checkbox "adjust brightness automatically" selected in the monitor panel of the system pref pane but you still get the contradicting "No" from the "About the Mac->System Report->Graphics/Display" view.I'm interested in something else.
If this parameter is initially present in these cards, then why is it equal to "No"? (on the screen)
Then he must equal "Yes".
Or am I not understanding something?
(After all, the participant BadBiscuit fulfilled all the conditions and produced all the necessary firmware. Or not ?)
There is a difference (and more than this chip) between the Ver 1.0 "00C" and the Ver. 1.1 "00D" card. Are you sure you have seen a picture of a working Ver 1.0 "00C" card without this chip?Ive been looking at photos for these cards and for all reports I’ve seen where cards have worked, the small chip, just next to the bottom right corner of the main chip, is missing. For all reports I’ve seen where the card didn’t work, this chip IS present. Could it be that simple?
intresting. but that don't explain why @Pascal Baillargeau have a working 00D card with the chip on it.Ive been looking at photos for these cards and for all reports I’ve seen where cards have worked, the small chip, just next to the bottom right corner of the main chip, is missing.

Well, end of suspense.
I apply this thermal paste (GC-Extreme by GELID), which by the way works better than attended. And had the opportunity to take photos of my card.
I was wrong to believe the listing visual was a picture of the real card.
It's not a 109-C769A1-00B -xx that i have, but a 109-C95847-00D-02.
I made a new benchmark too. There is nearly a 15, 20 degrees gain in load, i stay to nearly 72 degrees, and the animation is perfectly fluid.
After i flashed 580X_GOP.rom which is an overclock version of W7100_GOP.rom, benchmark is better but temps go a little bit too high (89,90) and i have choppy animation again. It could be manageable but i reverted back to W7100_GOP.rom.
Sorry for this chaos, but we can discard 109-C769A1-00B -xx, which is based on a Tonga chipset (not the same visual, size), and i can now confirm that there is a WX7100 with PCB serial number 109-C95847-00D-02 working, with W7100_GOP bios.
Also pay attention.I’ve seen where cards have worked, the small chip
So it turns out:You can have the checkbox "adjust brightness automatically" selected in the monitor panel of the system
NO to your WX7100 analysis:Also pay attention.
On working cards there is a small inscription at the bottom of the "V345 VER 1.1".
Unlike the inscription "V345 VER 1.0".
For example:
Post @meggle
and screen
So it turns out:
How would you check this box, then in the system the parameter "Automatically Adjust Brightness" will be equal "NO".
But automatically maintaining the backlight level will work correctly.
Did I understand everything correctly?![]()
good idea, maybe a google sheet.Has anybody downloaded all posted pictures and listed the success in some form?
I knew you have them all!
no, but i can creat the file in about 1 day. (maybe in the weekend)I knew you have them all!
Go ahead, we need probably just the link to the picture or better post on the thread, the type of the card and success or not. The less we copy from the source the better it can be maintained..
I bet a lot of readers here will like this kind of summary and a link to it on the post #1...
Did you install the AppleGraphicsControl extension in the end?my feedback
install 10.15.6 combo install > doesn't work
install using usb key with dosdue1 > ok
open core > ok
sleep/airplay > ok
graphic acceleration > ok
all is fine but you will need
1- after the first reboot while installing you will get a black screen > power off the iMac > power on and reset pram (alt + cmd + r + p), installation will continue
2- a second black screen at the end of the installation, do as 1
3- re-apply patch sleep/air
I installed AppleGraphicControl at the endDid you install the AppleGraphicsControl extension in the end?
I do not have installed it and the system is booting fine now...if you have an external display connected during the complete installation (miniDP to DVI) you see the active display moving to the external one while you experience a "black screen" on the internal LCD, but you can continue with the installation without resetting the PRAM on the external one.
At the very end everything is working fine.
Booting now using alt/option directly into Catalina (without OpenCore) works, too (no black screen). Of course you have no brightness control then...
