Grab the RAM chip by its edges and pull it straight out of its slot.

  • If two RAM chips are installed, repeat this process for the other chip.

I don't know if this matters, but if you are doing the 6 GB upgrade on the A2210, I put the 2 GB chip in the left slot and the 4 GB chip in the right slot (with the computer on its back and the monitor facing up and the memory compartment facing you).

Thsnk you for this tip.

Was it necessary to remove the stickers that are attached to the RAM BEFORE installing?

I currently have a 4GB memory module installed on an EMC 2210 in one of the memory slots. Can I still install the original 1GB ram in the other slot making it 5GB total memory?

I installed 2GB x2 to mine to upgrade from 1GB x2. It took just minutes and I used a regular philips screw driver I found around home. Pull hard on the black straps to get the memory out. It is working great with no problems. Good luck!

Thank you for the guide. I had 2GB. I took out 1 module to add a 4GB module. So easy and now my 2133 iMac is jaw dropping fast.

Hi Garison,

.

I hope you can answer my question. I have an iMac, medio 2007, Intel 20" EMC 2133.

.

RAM: (1GB + 1GB) 667 MHz DDR2 SDRAM.

.

I would like to make my iMac "jaw dropping fast" as well ;-)

.

Is it PC 5300 or PC 6400 I should buy?

.

And what setup wold you recommend? (1GB + 2GB), (1GB + 4GB), (2GB + 2GB) or (2GB + 4GB)?

.

Thanks,

Mikkel

The maximum memory for an iMac 20" - Early 2009 (ECM 2133) is 8Go (2*4Go) and not 6Go as said in the tutorial.

See Apple support page: https://support.apple.com/en-us/HT201191

This tutorial is not for the 2009. Model A1224 / Mid 2007 and Early 2008 / 2, 2.4, or 2.66 GHz Core 2 Duo processor

Hi there, Apple says maximum ram for 2210 model (20" Early 2008) is 4GB (2 modules x 2gb). This tutorial above says 6gb! Who is right? Anyone manage to install 6gb? Thanks
