    • Unplug your iMac's AC cord along with any peripheral devices.

    • Lay your iMac face-down on a soft, clean surface as shown.

    • Be sure there isn't any dirt or debris on your work surface, as it may scratch the glass panel on the front of your iMac. We recommend placing a towel between the iMac and the work surface.

    • Loosen the three Phillips screws securing the access door to the bottom edge of your iMac.

    • All three screws will remain captive in the access door.

    • Remove the access door.

    • Gently slide the black plastic RAM pull tab out from the RAM slot.

    • Pull the black plastic tab away from the bottom edge of the iMac to eject the module(s) on that side of the RAM bay.

    • This may require a bit of force.

    • When installing new RAM modules, it is important to orient them correctly.

    • Be sure the small notch cut into each RAM module (shown in the first picture) mates with the protrusion in each RAM slot (shown in the second picture).

    • Your iMac has four RAM slots. Be sure to slide each RAM module into its slot horizontally. This will prevent getting the modules stuck between two of the adjacent slots.

    • Once you have oriented the new RAM modules correctly, gently slide them completely into the iMac and use your thumbs to firmly seat them in their sockets.

    • Before beginning, unplug your iMac and lay it on a soft surface as shown.

    • Stick a suction cup near each of the two top corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

    • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

    • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

    • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

    • Remove the GPU from the GPU heat sink.

    • Make sure to apply a new layer of thermal paste to the face of the GPU (the area boxed in red) before reattaching the heat sink. Our thermal paste guide makes it easy.

    • Before installing new thermal paste and mounting a new GPU to the GPU heat sink, use the flat end of a spudger to push the VRAM thermal goop closer together so it will better contact the VRAM when the GPU is installed.

    • Do not use thermal paste on the VRAM chips (the black boxes around the GPU). The VRAM chips are shorter than the GPU, and therefore need thermal pads to make contact with the cooling element. Replacing the thermal pads with paste will cause the card to overheat and can potentially ruin it.

Hi everyone,

Which GPUs can you use as upgrades for this 2010 model? Mine has a Radeon 5670 512mb and I'd like something a bit more powerful...

Thanks!

Tom Edkins - Responder

lucky, i have a 256 mb card

Ethan Farmer -

Heh. I just replaced the 512mb 5670 card with the 256mb 4670 card.

Why, you might ask? Because of Mojave support. The 4670 is supported under Mojave but the 5670 is not…

larry.herzog -

One question:

i can put this GPU: NVIDIA GeForce GTX460M

on my iMac Mid 2011?

or i will have problems with the Drivers?

Miguel Alonso - Responder

Wonderful guide! First time I opened a imac.

I need to replace the LCD cable connector on the motherboard. It is broken and it caused a short circuit on the motherboard. On the motherboard, underneath the grafic card, I've found a fried SMD inductance (L9000 on the motherboard) in the powerline of the grafic card. I restored the powerline with some solder leaving the inductance out. Should be no problem.
