They are M2.5 x 8mm, countersunk. (At least that's what I used...)

I will, thanks. 🤣Bought once this package and found the right ones inside

Okay,
this is a classical situation. Because nobody is really clear in his description one has to do guesses. Sleep problems normally happen only on Catalina, Mojave and Big Sur and only on 2011 models. Root cause is in all cases the HD2000 iGPU.
So how could I know you are using still High Sierra when you talk about sleep problems?
It happens on High Sierra only with OpenCore and spoofing an iMacPro1,1 unless you patch the system properly. Since you are not using OC my only guess is the GPU is not working properly. All you guys hate me for this sentence. But I have seen during the last 12 month K3000M, K5000M, K41000M and K3100M doing exactly this in the iMac 2011 and I still own such a card (and my iMacs ran perfectly after a GPU swap). The misbehaving ones went into 2009/2010 systems.
Since I do not know what version of High Sierra you have installed on your iMac my only and last advice is: Do a clean new High Sierra installation, update the firmware to 87.0.0.0.0, and do not install any additional non Apple patcher packages. Update the system completely with all available Apple updates, instead.
If your system is still not waking up after sleep then move the K3100M over into your second non working iMac 2011 to cross check if the system itself is ok.
Happy disassembling!

thanks for the response....
Version info:
High Sierra 10.13.6 - with all updates. Boot Rom is 87.0.0.0.0
Processor is an i5-2400 (which does have the integrated GPU)

Or just set the power preferences to not go to sleep, which seems a lot easier and I don't have to take the system apart again.
The second iMac is going to get a GTX880M when I get some spare time. I just did the mods on the heat sink yesterday and mounted up the GPU, now I just need the time to put it in.

Hi guys, i'm gonna to buy a 27inch imac from mid 2011 and i wanted to know if i can put a brand new gtx 980m directly inside and if it's plug and play or if i need to flash the card
Hi, SevenOFF , you're gonna use the search function for this thread, keyword: GTX980m and find your answer right from the search result.
okay thanks just saw that option, so what's the best graphic card availble for that imac ? is it the 880m or an amd one ?
yeah saw that but appart from that one is there any other one instead of the gtx 880m ?
Because this one seem really pricey

The first post has two lists of cards that work (NVIDIA and AMD).
Your question is like asking which hamburger is the best. We could be here all day talking about hamburgers but in the end you have to choose what works for you.
If price is an issue to you, don't ask for the best. Ask for what is available near you, and match it with the list on post #1.
And the best saving solution is: Do not buy the iMac 2011 at all.
And lastly, just type your question in the search box, you'll find your answer there.
In most of the cases, you are not the first one to ask such a short question.

Concur with Nguyen completely.
It is still fair to upgrade an iMac you own if you are so dedicated to.
To buy a 10 years old unsupported iMac and an expansive metal compatible GPU that may not work even after all the demanding steps in flashing and installation and patching ? You better consider your return on investment seriously.
Consider the M1 MacMini or even a cheap PC for your aim.
Success!!
Although I am a lousy solder artist I managed with paste, heat gun, patience to solder the two 0K resistors somehow onto the board and can boot the iMac12,2 27 with this card and can use it with Big Sur.
THIS IS INSANLY GREAT!
(to cite the contributor of this thread)
Thanks for this development and post!
Note: bottom right corner of the picture in can see one of the resistors...

awesome work but since they are 0K resistors (essentialy jumpers) u cloud just solder a thin wire across
Did you look at the two tables in the first post? It is a wealth of information.
Заменил на туже карту. у меня грузится ОС но парой черный экран на Windows, а с блютуз и USB тоже таже тема поидее когда проблему дает при неудачной загрузке то это проблема какраз с блютуз и USB у меня именно так... пробовал записать Open core для решения проблемы с черным экраном но не встает незнаю с чем связяно. писал под сиеру
It is more easy to fix the little component than preparing a 2-3 mm long an nearly invisible wire. The costs of the resistors is 1 Euro per 100 pieces, shipping was more expensive

All I understand is: OC, Windows, and USB.
