macbook RAM?

[grosslyclever]

Hi, I have 4gb of RAM (2gb each) in my black macbook. Is it safe to put a 4gb stick and a 2gb stick? Can my macbook handle it? Also, if I want to upgrade to 6gb, can I keep one of my 2gb RAM sticks un my macbook and replace one with a 4gb?

If what I said above is possible, can someone send me a link to a 4gb stick?

I'm pretty sure the BlackBook can only handle a max of 4GB.

The Black MacBook can only hold up to 4GB of RAM.
