The Mid 2010 iMac supports 16 GB of memory officially, but you can install 32 GB of memory without any problem, so you can use a 8 GB RAM module without any problem. You can get the memory in OWC or Crucial > http://eshop.macsales.com/shop/memory/iMac/2010/DDR3_21.5_27

As mende says that machine will actually support 32 GB of ram, for details you can see http://www.everymac.com for any Mac equipment.
Be sure to only buy ram from Mac specialists as timing of the DIMM modules is critical. OWC and Crucial are the best and guarantee their ram to work. Avoid low-cost brands such as Kingston Value Ram and Corsair Vengeance as we have had a few users the past couple of weeks with the Corsair ram that would not work in a Mac. That is primarily PC ram being sold to people to use in Macs, and it is not accurate enough for a Mac.

...thanks for the extra info. is kingston generally not so good or do you mean a special »value « product line?

The Kingston Value Ram is a major source of problems, if you use the upper level Kingston, make sure it is specifically sold as Mac compatible and get a money back guarantee...some places charge a restocking fee if the product is returned.
OWC and Crucial do not do that and certify their memory for Macs.
