I want to upgrade memory in my mid-2010 21.5" iMac. I've found that Kingston 2GB module with product ID KVR1333D3S9 is available at my local store, and want to buy it.

iMac mid 2010 memory specification says...

You can use any Small-Outline dual inline memory
modules (SO-DIMMS) that meet all of these criteria:

PC3-10600, Unbuffered, Nonparity, 204-pin, 1333 MHz, DDR3 SDRAM

DIMMs with any of the following features do not work in the iMac (Mid 2010):

Registers or buffers, PLLs, ECC, Parity, EDO RAM

I've also found specification for this memory module, but it uses too much techno-speak and I'm still not sure if they go together. Basic parameters seems ok though. My question is ... is this the right memory module for new iMac?

My suggestion is:

Print out the page linked in the comment, take the printout to the store and tell them you want memory modules matching those specifications. No need to decipher some hard to understand memory spec from a pdf yourself.

Thanks. I wonder why this didn't occur to me ;-) I asked at my apple premium reseller and sure they have memory modules that fit into new imac at similar price (even bit cheaper). – random lurker Aug 5 '10 at 15:34
@random - I to sometimes forget that there are people out there that are paid to help me. I don't have to do things myself all the time. – Nifle Aug 5 '10 at 15:41

The Kingston KVR1333D3S9/2G memory matches the specs supplied in your question, it should work fine.
