Hello,
A similar question was asked by another German user on the site.
His answer was positive, so I guess it should be positive in your case too.
In case of a hold, don't hesitate to contact Apple support directly or to mention your exact model in the comments.
Sincerely,

That iMac takes max 16GB 1066 in 4 slots, so probably has 2x2GB and 2 slots free.
Looks like the usual upgrades are to add 2x4GB 1066 or replace with 4x4GB 1066,
so I would be quite surprised if 2x8GB 1333 will work.
It's late 2009 so don't expect any more High Sierra updates :(
I also read something about a fan noise issue if you are replacing the original drive.
Hallo
Gemäss everymac haben sie richtig ausgewählt.

RAM Type: PC3-8500 DDR3 Min. RAM Speed: 1066 MHz
Details: Supports 1066 MHz PC3-8500 DDR3 SDRAM.
Also see: How do you upgrade the RAM in the "Mid-2009" 13-Inch, 15-Inch, and 17-Inch MacBook Pro Core 2 Duo models? How much RAM of what type do they support?
For MacBook Pro 2012 this one:
Item no. 374057
Corsair CMSA8GX3M1A1600C11 (1x, 8GB, DDR3L-RAM, unbuffered) --> if 8GB necessary
or
item no. 374058
Corsair CMSA16GX3M2A1600C11 (2x, 8GB, DDR3L-RAM, unbuffered) --> if 16GB necessary
Good luck & LG
They don't fit your model. However, your model unofficially supports 16GB. I would then recommend these: Corsair CMSA16GX3M2A1600C11 (2x, 8GB, DDR3L-RAM, unbuffered)
These fit better: Corsair Mac Memory CMSA16GX3M2A1600C11 (2x, 8GB, DDR3L-RAM, unbuffered)
Here is the spec. in detail, what you need exactly: https://support.apple.com/de-ch/HT201191#1
Apple lists the RAM requirements on a support page: https://support.apple.com/de-ch/HT201165
If you filter by the criteria, you can see what is available. Apparently 8gb is the maximum. So you only need 1 x 4gb.
Hoi, gemäss everymac sollte das gehen
