I've started virtualizing Windows 7 on my Mac and I've realized 4GB of ram simply isn't enough for listening to music, surfing the web, virtualizing Windows, and running a compiler all at once.
The first thing I did was look on Apple's site and see what specs I needed to look for..I bought my iMac in the spring of last year so the specs for new ram are as follows: 1333MHz DDR3 (PC3-10600)
So I read that and thought, okay, and then I read their price, $ 200.00 for just 4 GB. Wait a second, maybe a little out of my price range. Then I hit up sites such as NewEgg, and found some pretty good deals; however, I found that some of them were labeled SDRAM and some SO-DIMM, and I guess my question to you folks is: What are the differences between SDRAM and SO-DIMM RAM, and which should I use for my iMac?
