try to connect to your imac via another computer using a usb stick like if you want to flash the graphic card
etablish connection then use nvflash
if no nvida card found you will get the answer.... RIP

3rd LED will only be on with modified ROMs that are made which add LED logic board support. @FlorisVN post:#3455.
4th LED is communication with LCD screen (LCD screen physically connected).
What's concerning is the 100% fan speeds, check all your other connections again.

Thanks, that's a shame as I was looking to use a GTX 770m. Has anyone in this thread successfully used cooling mods like copper shims long term that you know of?
Also
Anyone in Europe looking to sell a larger heatsink from a 27"? The three pipes design
Did you flash the card with VBios from post #1?uffff... my GTX 860 has an Black screen is my card broken?
boot "noise" black screen..... 20 sec... Fan is loud "black screen" ...i switch to my AMD 6770 and this card is working..... can anyone help me?
must i buy an new card

I bought one heatskink from eBay (France, PlaceDuMac). Don't use nothing on the back of the card (like copper pads). The card doesn't need it. Mod the heatskink to perfect assembly the mxm card, use good thermal pads and paste. And use a small x-bracket, not the larger one (if you have a 6770, that x-bracket would be perfect).

Exactly. And the K2100m is a good enough card.
I did some gaming on Bootcamp yesterday. The 6770m could barely maintained 20fps on overwatch on low.
The k2100m last night games at 60fps (54fps 1%low) at 1080p medium settings. The improvement is massive.
Yeah I think you might be right! I'd really love to use a GTX 770 but buying a new heatsink to upgrade to such an old card might be too much. Have you played any other games with your K2100M?
I found this thing on eBay - an HP K2100m, looks like its a regular MXM form factor in a huge heatsink / fan case thing. anyone know if I could take that lot off to reveal something I could use?
here's another pic:
If trying to flash with an HP card you most likely need to use a clip to flash. From what I read there is no external display trying to flash with the HP ROM. I also read you could SSH flash blindly with Linux, but that likely requires a decent amount of preparation setting up wifi copying files to directories etc.Yeah I think you might be right!

Also with a clip it may appear all pins are touching the legs of the EEPROM but it could be slightly off. Just fair warning. But I have always had success with flashing my cards.
That’s subject your HP card comes with a VBIOS chip which is unlikely. That’s why DELL cards are a must.
ALL the HP K1100M and K2100M cards I have seen have a rom chip without exception.
Yup which is not what is being modified here.
The HP cards don’t have a separate EEPROM that stores DELL’s custom VBIOS.
The CH314a was the old way to load Nick custom VBIOS on the card until we were able to use the nvflash utility.
So to cut the story short, HP card can’t be modded. They may get you to the desktop, but no backlight control, no EFI bootscreen, etc.

my k2100m wasn't recognize no nvidia graphic adapter I am waiting for a flasher... last chance
I prefer a clean instal then timemachine is your friend
May I am wrong but you got to unselect legacy graphic card option , or thing like that
when catalina install is done, start again using the usb stick of catalina then choose post install and unselect the option about old graphic card, I prefer select force Ktext too
start again normally and enjoy

I installed an HP K2100m with zero difficulty. I used the Linux USB and SSH to update the firmware. It was honestly quite easy.
I am not sure where you got your information from.
Hi guys,
it is amazing to see that a lot of people want to revive their 2011 iMacs aswell. It is a fantastic machine and I would love to use it regularly again. For that to happen, it needs to have Catalina running. Since the inital post is quite old and I cannot read 206 pages, my question is:
Would anybody be so kind to update me on the latest status? I want my 27 inch late 2011 to run Catalina smoothly.
Is there any GPU recommended that does not need requiere a flash, is plug and play compatible and still offers backlight control and sidecar?
I have to open my imac anyways to swap the PSU.
Thanks a lot

No, there is no such GPU here!
There are commercial offers available, though.
No, the initial post has been updated only few days ago to cover the most recent software developments. You will find it there, probably except the findings of the users playing around with the latest software update.
Until we become Borg you cannot except that each "individual" experience is flowing back to a common conscience, immediately.
The best I can recommend is getting a WX 4170 or WX 7100, if available somewhere.
But you have to flash it, damn it. And install OpenCore, and configure it!
