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

[Flotation]

Internetzel, you are right.
I looked thru the performance tables.
All reported success with benchmarking in 21.5" iMacs are using nVidia GPUs.

So, I do think Floatation achieved a milestone in having a WX4150 running in his 21.5" iMac 2010.
Being able to flash his GPU and get his card POSTing is an important step.
He was able to have an internal display with an external dongle or display connected. That partly solved the display problem / black screen problem despite not a clean solution but just a small compromise.

With the GPU installed, SSD can't be connected and booted from. It appears to me to be a power issue.
On monitoring the power consumption of my GPU with iStat, I noticed on & off significant power hype even with usual internet browsing. It is possible during booting, the initial power surge on cold starting (GPU + SSD) may overload the power supply and prevent the normal POSTing and booting. Also the 5V supply line to the SSD could be stressed if it is also utilized by other components. I can only conjecture that the USB interface may dampen the power surge or has more power juice in the internal wiring if it is not shared by other USB devices. How about disconnecting the DVD drive to see whether enough power can be available to remedy the situation. Just brain-storming as I am not a computer technician Besides, the Mac vBIOS of WX4150 is overclocked. I am not certainly whether by downclocking it or adjusting its power curve table would reduce the current requirement during operation.

Certainly his WX4150 is working and can be sold for some value to other users in need if the project is abandoned

I got the system running Catalina with internal display with OpenCore. No more need for the external display or a dongle. Everything is fine except the Problem with the SSD. I already had the DVD drive disconnected. I ordered a ODD to SSD adapter to test the SSD on the other SATA port. Seems like the second port is using another supply line.

There are two BIOS for the WX4150 in this thread. Are both overclocked? I'm using the DELL one from the first post. Maybe I should try the other one. But I don't think this would make a difference. As long the iMac doesn't power up, the BIOS is doing nothing.

Update:
I took a closer look at the power consumption of the stock cards. It's between 15W and 35W. The WX4150 has a TDP of 50W and TBP 45W. This could be the problem as long the HDD/SSD and the graphics card are drawing power from the same lines. I also upgraded the CPU to an i5-680. Maybe the power supply is too small and this is the only significant difference between the 21,5 and the 27 iMac 2010. Otherwise the k2100m has a TGP of 55W and is working.

I want to thank the forum and especially every developer who worked on making BIOS's for better GPU's for our old trusty iMacs. I have upgraded two 2011 27" iMacs with a 770M and just now one with a 780M for brightness control and a more native feeling. After some issues and solutions found on this thread my iMac now works perfectly with a full bootscreen and full brightness control with macOS Catalina. I also reinstalled windows 10 in UEFI mode and works great (without sound working, but that is not an issue for me). All without OpenCore since I don't think it will benefit me much.

It idles at CPU temperatures of 36C and gpu 37C since the screen is not blasting at full brightness. The 770M (without brightness control) idled at 45-50C, so a big improvement which is definitely noticeable.

There is however maybe a small short in the GPU assembly since the power button only works when pressed twice and sometimes USB and Bluetooth don't work after booting up, rebooting a few times seems to fix it (this is a problem I did not have with a 770M in this exact machine) but I'll open up the iMac somewhere next week to see if booting without the heat pipe fixes the problem, then I know I have to isolate the card a little better.

All in all, a perfect performing iMac nonetheless with a superb increase in video performance versus the original 2GB AMD card. In windows 10 it almost matched the GPU performance of my other 2017 5k iMac with a score of 3000 versus 4500 (Unigine Valley) while this is a machine from 2011!

 

[Onizuka18]

J'ai créé une petite application qui corrige le problème de profondeur de couleur au démarrage pour certaines cartes, comme la 780M avec la ROM de [USER = 1199855] @ nikey22 [/ USER]. Après le démarrage, démarrez cette application, l'écran devrait devenir noir pendant une seconde et les couleurs / performances devraient être bonnes. Semble bien fonctionner pour moi mais nécessite évidemment des tests en premier. Auparavant, je devais mettre mon iMac en veille au moins une fois ou changer la résolution de l'écran dans les deux sens pour résoudre ce problème, maintenant c'est un peu plus rapide car je l'ai configuré de manière à ce qu'il s'exécute automatiquement au démarrage.

Téléchargement: https://github.com/passatgt/imac-color-depth-fix

Utilisation: double-cliquez simplement sur imaccolordepthfix pour exécuter. Vous pouvez l'ajouter à vos éléments de connexion (paramètres système / utilisateurs / éléments de connexion), afin qu'il s'exécute automatiquement à un nouveau démarrage.

Hello thanks for the software it works on Mojave, Catalina. This is not High sierra compatible do you have a compatible version please

Peace

 

[Roman78]

I noticed the BIOS-Link on #1 for the K3000m is gone. Is there some news?

It is working fine using the HP Bios, but sadly the modified Bios did not works fine.

Hi guys can i have some help please.

I added e3-1275 and k4100M card to my 2011 27' iMac and loaded Catalina, I wanted to wait before going to Big Sur.

I used;

Xander flash with Nikey22 bios
Catalina patcher by DosDude1
and then Hackintool to add intelsandybridgegrafics

I did NOT use OpenCore because I could not find a dmg file which i could download as they are all showing as having a virus.

Everything works as intended apart from 2 things.

1) CPU is still showing as i5 2.7 instead of Xeon in Abut this Mac
2) Sleep bug

This is the crash report.

The BIOS posted by @Nick [D]vB in the AMD Beta4 set is not really overclocked. You may check this. Check the WX7100 BIOS link, should lead you to this post and set. Or search for it, it usually works...

Hey buddy thanks for the fast reply, I did read through it but maybe I don't understand how am I supposed to create a USB stick from a github repo. any clues? does it have to have bootload on it? as well as Catalina install? I"m a bit confused

1) CPU is still showing as i5 2.7 instead of Xeon in Abut this Mac
2) Sleep bug

1) This is the expected behavior, iMac firmware won't recognize Xeon (but if you used Geekbench, for instance, it should show the actual CPU)
2) Check the iMac 2011 CPU upgrade thread: it seems that all Xeon processors cause the bug, with or without iGPU.

To create an OC boot disk, AFAIK you just need to format a partition of a GPT partitioned disk using FAT32 and copy the files to it. The root directory should contain an EFI folder if you did it right.

hey man, so you are saying the xeon is causing the sleep bug regardless of the iGPU??? Oh man, that was the reason i went for it. would patching this help?

[358]

is there even any point for me to install opencore now that I have catalina running without issue (apart from the sleep bug which i can get around by creating a schedule to switch on and off) if the 1275 is inherently the issue, it sounds like a waste of time. Please correct me if I am wrong. thanks again, guys. It is truly amazing how much time and love has been invested here..... kudos

 

[highvoltage12v]

I'm not sure whether or not we had reports of successful installations of a WX4130/WX4150 in a 21.5" iMac 2009/2010 at all. Maybe they work in the 27" models only?

I had my RX560m (don't buy one, thread readers) working in my 2010 21.5" iMac, along with my WX4130 working briefly. Switched back to the k2100m for bootscreens but can switch back to the wx4130m with the new improvements.

The 21.5" 2010 would post with the 560m while it wouldn't in the 2011 models. For those who are new to the thread, the 560M (Dell) would cause the SMC to crash causing the fans to go to 100% Temps to go to null values of 129C and the CPU to lock at 800MHz. This would happen anytime the card would hit 'boost'. No firmware fixes could fix this issue, hardware related.

** NVIDIA Quadro K3100M Mac Edition ROM **
Genuine Native Boot Screen & Brightness Control​

View attachment 942193


Pre-installation Requirements:
- iMac12,2 (27-inch Mid 2011) Mac-942B59F58194171B (Tested machine)
- BootROM: 87.0.0.0.0. Please use High Sierra to update your BootROM to latest version.

- GPU Variant: N15E-Q1-A2

- Hynix GDDR5 Die Generation variants
View attachment 1687878
H5GQ2H24AFR - Hynix 1st Generation die - VDD 1.5V, use K3100M_AFR.rom
H5GC2H24BFR - Hynix 2nd Generation die - VDD 1.35V, use K3100M_BFR.rom
H5GQ2H24BFR - Hynix 2nd Generation die - VDD 1.5V, use K3100M_BFR.rom

known working cards:
Dell K3100M vbios: 80.04.B0.00.0A
HP K3100M vbios: 80.04.CD.00.0A. PN: 744354-001

This ROM does not require a 3rd party bootloader like OpenCore.
This ROM is build on the same principles as my K4100M. Unfortunately, the color-pixel bug is still present. But I am working on it. The brightness will need to be adjusted via a kext as previous. I have a feeling that the native brightness dimness is also inline with the same generic driver bug previously mentioned. The rom has a modest clock table boost as well.

Post-installation Requirements:
Brightness Control Stepping Mod:
-Turn computer on, hold down Command(⌘)-R
-Choose Utilities > Terminal
-Enter:csrutil disable
-Reboot
-Download and open 'Kext Utility v2.6.6'

-Navigate to S/L/E (System/Library/Extensions)
-Copy "AppleBacklight.kext" to Desktop
-Edit: AppleBacklight.kext/Contents/Info.plist
-Scroll down to: IOKitPersonalities > AppleIntelPanelA > ApplePanels
-There you find several Apple LCD profiles.
-For the iMac 2011 27" machine locate:

<key>F10Ta007</key>
<data>
ABEABgALABQAHAAnADMAPwBOAFwAZwBzAIEAkQClAL8A2wD/
</data>

-Change the <data> section to:
ABEAAgA3AF8AigCzAOsBJAFnAakB1AIJAlQCogL4A00DlgRpBGk=

-Drag your modded kext into Kext Utility, allow it correct permissions
-Applebacklight.kext.bak folder will be created
-Reboot

The above data pattern will allow for a wider span of steppings for the brightness control and utilizes more of the capacity of the HD3000. If you have a different machine, your panel ID can be found by going to System Preferences > Displays > Color > Open Profile > mmod

warning: please remember this is a WSON based card. You will be unable to recover from a bad flash with clip.

I presume that k4100m also have the same kind of solution?

 

[Terros]

Any advice here - attempted OpenCore with my WX7100 - Set to boot the loader USB > Booted and kept freezing on the Boot picker - Left it awhile and eventually hard powere off and unplugged the USB.

Now I get no picture (even with external screen connected and PRAM reset done)

This is with High Sierra. Can't seem to blind boot pick either holding alt to OSX or Windows.

Update: Seem to have gotten it working again - Put old 780M in and it was some sort of corrupt Windows boot error it was stuck on and I could see it now with the 780M so managed to Alt boot pick into OSX (with no heatsink on the 780M) and force it to boot only to OSX.

Put the 7100 back in and it's working now with external screen to OSX.

Now to decide if I want to attempt OpenCore off the USB again....

Try booting from an OpenCore SD instead of USB; sounds like your USB may have had issues. Good thought trying an external screen. That would have been my first suggestion.

Both of you have to disable SIP, make root writable and may than use kext utility to install a new extension. Try to follow the guides completely.

 

[Ausdauersportler]

Maybe the first post should be edited. I will do further testing. It's really weird.

There is at least one known user with a working HP 4150 in 21.5 2011 and 21.5 2011 - I am tired of this.
The cards are simply complicated to get to work and there is no guarantee at all. Exactly that has been written to the first post.
You choose to buy it anyway, now what? Add another warning in front of the warning?

Could you please help me get this across the line. Much appreciated.

Sleep is broken with most Xeon CPU. Sleep is broken unless you install the HD3000 extensions back - first post. Did you read it?

Bonjour,

I confirm what Ausdauersportler says in #12,448 post, I did it knowingly, I was lucky that it worked, I think it's important to specify it.

Both of you have to disable SIP, make root writable and may than use kext utility to install a new extension. Try to follow the guides completely.

I did disable the SIP first before proceeding with kext editing but the error is still there. I renabled SIP and redid the procedure with same error. I repeated this process 3times just to be sure that i tried enough times before calling it quits - same error in kext utility. Maybe the instruction works for afr memory but not for bfr memory.
