Hello,

Currently I have 2 GB of ram in my macbook (2x1GB), and was looking at upgrading memory. I've heard there was some issues with doing the 3GB or 4GB (only 3.3GB usable) option such as the system just booting up to a black screen.

Who would you reccomend to buy the memory from; either the 2x2GB set or the single 2GB stick. Also, how much is the performance increase worth by using the 4GB dual channel mode instead of 3GB?

Intel iMac 20", Mac OS X (10.4.7), 2GB Ram, 250GB Hard Drive, 256MB Video
