iMac RAM compatability?

Hi,

I've had an old PC laying around for awhile and finally decided to do something with it. I found 2 512MB RAM modules and want to add it to my mid-2010 iMac (4gb RAM, 3.06 ghz) but I am not sure if it is completely compatible. It is about 4 or 5 years old and I can't find much info on it on Google or the module. I posted a link to some pictures of it below to see if anyone could see something I missed.

Any help would be awesome.

Thanks!

You can go to , about this Mac, and get all the info you need, but these modules are of going to be of little to no benefit to you, unless you are maxing out your RAM even if they are compatible.
Also, it is better to have matching RAM, and the 1 GB increase may really work against you.
Your iMac has 4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM slots, each capable of having 4GB RAM in each.

Thanks for the help. I do frequently max out my RAM but I can live without it.

No RAM from 4-5 yrs ago is going to go into a 2010 Mac, or for that matter in any 2010 computer. The DDR3 RAM being used today was not even in existence 4 yrs ago.
