Adding RAM

[Tango Charlie]

The iMacs ship, by default, with 4GB of RAM in the form of 2x2GB sticks, right? And there are four RAM slots in the machine?

Question:

Can I stick two 4GB sticks in the other two slots?

Or do they have to match?

Yeah, you can do that

Yeah, you can do that

Are you aware of any performance hit or other side-effects?

There shouldn't be any because modern memory controllers can handle mixed RAM just fine.

Thanks for the help, and kudos to you for being such a ninja around here.
