This is not plug and play solution.

-- You must know your iMac model and year, your old graphics model, and read the following description carefully, so you can know what items you need to buy.

-- You need to mod your old heatsink, and learn how to assemble the card, how to use OpenCore (OC) / OpenCore-Legacy-Patcher (OCLP).

-- You need to know that this is not Apple original graphics, some features do not work, read the "Feature" in the description carefully.

1. iMac 11,1 needs to use external display to boot into MacOS, and run OCLP to build new OC, then internal display can work. So, you need a Thunderbolt / MiniDP to VGA / HDMI / DVI cable / adapter to get external display at beginning. If you don't have the cable, search from my store or contact me for the link.

If you get a black screen issue with your iMac 11,1, contact me for the solution first.

 

2. iMac12,2 with old graphics HD 6970M 1GB / 2GB, must buy new X-bracket for MAM3.0 type A. The old X-bracket can't fit. Don't try to mod / cut your old X-bracket, the modded / cut X-bracket will damage the video card.

 

3. It is drop-in fit for 21.5 inch and 27 inch heatsinks, no modification needed.

 

4. Need OCLP (OpenCore-Legacy-Patcher) for High Sierra / Mojave / Catalina / Big Sur / Monterey / Ventura, please contact me for the method to install Ventura after you place order. OCLP will fix the level of brightness and provide OpenCore boot picker. Need to post "nVidia Kepler patch" in Monterey.

 

5. GPU Temperature Monitoring does not control the fan! Move and fix the ODD sensor (CD-ROM temperature sensor) to the GPU heatsink, and use MacsFanControl to set ODD fan run in "full blast".
