iMac Mid 2009 20" (EDU model) RAM Upgrade?

[Mark0]

I am about to receive a 20" iMac Mid 2009 (Education only) model that runs the Core 2 Duo 2.0Ghz and has 4Gb 1067MHz DDR3 RAM installed. I have read conflicting stories about RAM upgrades.

EveryMac seems to say that when this model was initially released, there was an EFI limitation that restricted this particular model to 4Gb max RAM but that the restriction was lifted at a later date and 8Gb is possible.

I have read conflicting information elsewhere and nothing concrete.

I'd like to upgrade using 2x4Gb 1067Mhz Crucial memory DIMMs but I am reluctant to buy some try it out in case it doesn't work.

I took a note of a serial number from a sample machine but I am not sure if it will be the actual machine I receive (there are 9 being auctioned off). If anyone can check for me using that serial, please let me know! It is: VM933MVH6MH

Has anyone had any experience with this issue or could check for me?

Thanks in advance,

M.

Yep, max RAM is 8GB.

Thank you very much for the information and the speedy reply. I am glad that it is good news!

You can also find the full specs here: http://www.everymac.com/systems/app...inch-aluminum-early-2009-education-specs.html

It takes 2x4GB of PC3-8500 RAM which you can buy cheaply.

Thanks again. I am curious as to why it comes up as an Early 2009 model in that model information based on serial number and not a Mid 2009?

Probably because the education model, released in mid-2009, is a slower version of the normal early-2009.

All went according to plan
