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

[Ghiro700]

Sorry Ausdauersportler, but no-one said that DHCP is not activated by default. I am convinced DHCP will work on xanderons boot stick in most cases. But in my case DHCP boot automation doesn't work (maybe network setup or whatever). And I strongly believe there are others also getting stuck at this point for some reason. I found some hints here in that forum. I tried different USB sticks, iMac is always connected via ethernet and I never changed configs on xanderons boot stick. And of course, I waited plenty of minutes to give GRML more than sufficient time to boot completely (went out with the dog i.e.). Situation is still the same and I can proof this easily by looking at GRML on internal display and keeping an eye on router information, only coming up for GRML by using key strokes described. This is not meant to confuse somebody and I really appreciate this thread and all the good work and information, especially your work Ausdauersportler (I am following you for good reasons). I am just glad to help Kranny36. I don't need to get this information on page 1 or in xanderons post.View attachment 1731970

Hello, I think I have the same problem. I am unable to update my iMac 2011 via ssh command after installing the new AMD 4170. I am not able to update the bios because no IP is assigned to the iMac. I have tested my USB key several times and it works on other computers. The router is configured with automatic DHCP and all other devices are correctly recognized with assigned IPs. Anyone able to help me? Other solutions to update the bios? Other solution to receive an IP from the router? Thank you

1. Did you test it before changing cards?
2. Are you booting with all drives disconnected, but the Linux on?
3. Are you connected with ethernet?

I didn't test before changing card
All drive are disconnected
I am connected via ethernet

in addition to that two out of four led on the motherboard are on.

Thank you

Try a different usb port, try clean pram

you mean to start pressin CMD+alt+P+R?

 

[peekpt]

you mean to start pressin CMD+alt+P+R?

Yes, until it reboots

 

[peekpt]

Silly question: Did you insert the memory?
You don't have to connect the screen to do this, the fans will blow because the lack of screen sensor, but that's normal.

Yes I insert just 2 DIMM on the left bay, the screen is not connected and the fans start silent and after few second blow loudly.
i just noticed that i don't hear the boom on startup is it normal?
Could it be better to put the old card and test booting with USB?

When you clean pram and the speakers are connected you should ear a big Dong!
Check if you connected the usb port connectors bottom right that metal thingy...
Take the mains power cord off and remove the cell battery wait 1 minute and connect it again and retry. Is anyway you can check the usb like a blinking led on the dongle or something

 

[eablokker]

What does „NOT working„ mean. Can you give more details on that?

High Sierra boot up progress bar gets stuck at about 75%. Seems to be just before the screen brightness would normally dim on a normal boot up with an earlier version of OpenCore, so I'm assuming it's something to do with initializing brightness or the GPU.

 

[bielousov.com]

So I took iMac apart once again, reinstalled heatsink without thermo pads, installed High Sierra alongside the Catalina, tried NVIDIA native and web driver, and switched between 780M ROM from @Nick [D]vB and @nikey22 (in fact used 2 versions of the former) and the result is conclusive:

With @Nick [D]vB ROM there's no backlight control and sometimes PRAM reset needed, the heatsink temp is higher (probably due to the extensive heat from LCD), but there's no Kernel Panic.

With @nikey22 ROM everything works natively and cooler, but I'm getting Kernel panic after ~15 min of constant high GPU load. I guess next step for me is installing a BootCamp Windows and reproducing issue there, then (if reproducible), playing with frequencies (I still suspect the Boost 2.0) and trying to edit @nikey22 BIOS to disable overclocking.

One thing I noted is that they are based of different BIO version, so presumably different manufacturers?
Maybe that's what's causing the issue? Note that OEM Alienware has lower core/boost frequency than others.
Again, Windows + GPUz would tell me more.

@nikey22 is there anything you changed about the frequencies or voltage?

 

[splifingate]

Soooo... Did it work? I still see just one sold so presumably it's only you!

heh . . . still in the anti-stat wrap <s>

Prioritised home-infrastructure upgrades top the list . . . awaiting work table(s), and time.

First is opening/cleaning the [working] 27" ACD, then the [non-working] iMac . . .

. . . both were absolutely free; but, still, I'm gana be right-miffed if the card dn't work 8-/

I am currently running my iMac with the Catalina installed via the patcher with the original AMD 6970M card. It runs fine aside from the sluggish graphic performance which is slowly annoying me to the point that I want to try the GPU upgrade.

I'm considering some options and reading the guide of p1, I note this:

Install the lastest Apple firmware for your iMac

Will I need to do this if I have Catalina installed via the patcher?When i run the command to check integrity it retuns:

EFI Version: IM121.88Z.F000.B00.1906140041

Thnaks.

The following guide will work on any MXM swapped card that has Brightness control enabled either through OpenCore (K2100m/K1100M) or Natively (K4100M) doing so allows for the Native Apple kext to be used and Not AppleBacklightFixup.kext

Here is a short guide on how to create your own AppleBacklight.kext for the 27” 2011 (F10Ta007) iMac. The same could be done for the 2010 iMac (F10T9cd7) and 2009 iMac (F10T921e)

1. Navigate to /System/Library/Extensions, find the AppleBacklight.kext and drag it to the Desktop.

View attachment 936404

2. Right click on the kext to show package contents open contents/info.plist. with TextEdit.

View attachment 936405



3 With info.plist Open in we need to Find the original value “F10Ta007”/“F10T9cd7/“F10Ta007” and NULL it out, This value is based on your iMacs Display year/Model. Enter Null or whatever value you want here.


4. Now to Fix Brightness we need to Replace the screen Value to the one that belonged to a 21.5” iMac, this Value is F10Ta00cM. Find this value using Find in TextEdit.


5. Replace Value F10Ta00cM with the one for your iMac’s Display model, I’m using a 2011 27” so the value is “F10Ta007”

View attachment 936407

<key>F10Ta007</key>    (2011 Model used)
<data>
ABEAGAA3AF8AigCzAOsBJAFnAakB1AIJAlQCogL4A00D
</data>

Make sure your Data entry looks like this one above. Save info.plist

6. Reinstall AppleBacklight.kext using kext Utility. Catalina users need to Unlock their System Partition using Hackintool first.

You should Now have proper (2009-2011) 27” iMac Backlight stepping that will properly Dim and raise you’re LCD to full brightness.

I see you have a 21.5" iMac what size MXM card did you fit into your iMac?

Dear highvoltage12v,

Thanks for the amazing work! Can I check if "2009 iMac (F10T921e)" was a typo? Because I cannot find the key F10T921e in the plist. Later on you mentioned the following:

original value “F10Ta007”/“F10T9cd7/“F10Ta007” and NULL it out

Do you mean that we can just treat the display key for 2009 iMac as F10Ta007?

Thanks!

Hi!

I wonder how you guys dig this post out of 10.000 others. From my current understanding the AppleBacklightFixup.kext has included these kind of patching. For that reason it has been included to all OC packages and I guess to all installer packages I provided for Sierra&HighSierra/Mojave/Catalina , too.

Once in a while we find a rare white unicorn, i.e. a new display type that has not been added there. In case adding the AppleBacklightFixup.kext to your installation does not fix the max brightness issue your have likely such a display.

What was you question exactly?

Hello, I tested all the solutions also on another iMac 2009. The problem is always the same no IP ‎assignment. I believe the problem may be the wx4170 video card. Whenever it is connected no IP. With the original card it sometimes assigns IP but then the connection is not stable and doesn't allow to flash the bios.
What can I do more? When the GPU is installed no Dong on start up on both iMac.

If you can't flash in Linux via SSH, Install windows and flash there. Macintoshmen on youtube has a step by step guide flashing his gtx765m.

Edit: here's the link

The most prominent changes during the last months came with the boot-args and the csr-active-config. I reset them in the latest version within the NVIDIA plist (not Big Sur).

I read your post

You can use the CH341A clip programmer to flash the WX4170 if your Linux flash utility does not work. Honestly I do not understand how an DHCP connection over a wire can be unstable?

How is your other device connected, the one you are going to use to enter the flash commands connected with SSH? I have two cable based iMacs connected to a recent FritzBox 7530 and had *never* problems. Once in one year I had to reset the box just because I could not believe to have a broken ethernet port - it was broken and a thunderbolt<->ethernet connector did the trick.

 

[Ghiro700]

@Vego17, Hey man, what happened with your WX7100? Any luck getting it going? Did you at least got it to boot?



What about you @Emilio306 ?

--

In the other news, I finally finished my first AMD implementation - my WX4170 project. Once again huge thanks to everyone contributing to this forum, especially to @Nick [D]vB (for the rom), @highvoltage12v (for the kext/framework work), @Ausdauersportler (for the support, the idea bouncing and sharing his OC experience), and all others here who have actively worked, tested and spent plenty of hours on building this knowledge.

So, I can report working 27", 2011 model with WX4170 and OC. Full HW Acceleration, Airplay, Boot Menu, brightness control. In essence all that I was missing with the GTX series, apart from the performance (maybe).

2 lessons I learnt with the WX4170 in relation to the setup:

• Heatsink does not require modification, but, you need to be generous with the K5 on the vrams, as they do not sit well on the heatsink Heatsink turns out requires modification of the VRAM cooling sections. I had to file these sections flat for the VRAM to sit flash with the heatsink and to loose the gap between the GPU and the copper plate. This mod made about 30C difference in the GPU temps, especially under load.
• I needed to put a piece of electrical tape on the left side of the card (when looking at the GPU), because, I believe some of the components were touching the heatsink which in turn resulted in boot problems initially. Coils were fine.

In the meantime my WX7100 project has regressed again. As @Ausdauersportler already explained, we ended without successful installation on the 2011 model, so I am eagerly waiting for a replacement card (the card was bad).

Hello I'm having trouble updating the WX4170, could you send me some photos of the heatsink modification and the position relative to the electrical tape? My problem is that the IP address is not assigned correctly with the Linux method and that both iMac 2011 and iMac 2009 do not have the Dong at startup. On iMac 2011 I have only two led on.
Thank you

Fully agree with you, but the reality is that a moment it appears and immediately afterwards via SSH it is no longer reachable. There are at least 78 devices on my system that have an IP assigned and none have the same problem.
Does the fact that there is no Dong is not synonymous of a problem loading something on startup?
I haven't modified the heatsink, can this somehow prevent it from working?
In my opinion the heatsink seems to be in contact well with the GPU, with regard to the ram they only touch halfway

There is a big square metal coil on the top left of the card, when you turn the card to install on the sink it is on the top right (down) side.

This part may touch the metal part if the sink and you can avoid this putting a piece to electrical tape or Tesa or M3 in between. This is not a serious as with the NVIDIA card where your have to grind!!

If you have no boot sound/chime something is broken with your system. A 2011 will have a chime even without a GPU installed, possibly the 2009, too.

Reset the connections from your router and clear the lease table to make sure you are not interfering with other devices. The reality is you have to deal with your network and hardware problems yourself. Nobody can patch this remotely away.

You should get a 15mmx15mm copper plate 0.5 to 1.0 mm thick to put it between GPU and copper part of the sink. It may be that your system shuts down silently because after just a few minutes the GPU thermo sensor reports overheating. I had this with sloppy installed NVIDIA cards more than one time.

You need a normal thermal paste for the GPU and K5 pro for all other components including the coils. Just take a look at the original GPU, you will see exactly where the K5 has to go.

You can find all this on the first post, too!

Thank you for your reply. I 'll start again. I bought the CH341A clip programmer and I will check again all the steps following first post guide.
Thank you I will post my update.

Hey anybody,

first of all! thank you all for this remarkable thread. Got my iMac 09 running for about a year with my 765m and its great. at least sometimes... there is an issue I can't find when I google after it. and it seams that even in this tread nobody got something equal. so here is my issue...

the Mac works great until it suddenly got a black screen und fall off. after reboot I got my error report saying cpu panic nvda:setpowerstate... See error massage in the end.

i have everything off. sleep stays at "never" all checkmarks are deselected. Temps are okay (about 50°C gpu heatsink and 45°C average CPU Core). 765m got the bios from nick. I'm running Catalina but the issue comes with HS also.

Catalina is freshly installed without the Patches for Metal.

Did I miss installing a Kext? Did I get a Bad Graphic card?

any ideas? somebody?

Hello,

thanks for the guide and the bios files. I sucessfully installed and flashed a gtx 870M through linux. Bootscreen is up again and booting normally into MacOS High Sierra ( I plan on upgrading to Big sur but haven't done yet). I have some troubles with the GPU in my Windows Partition. Since I flashed the GPU with the custom vBios the Nvdia Drivers won't install. It just says "the graphics drive rcouldn't find compatible hardware" I already tried DDU , patched the files from the Nvdia installer with my graphics Hardware ID but nothing is working. Is this a common problem?
