Just add the new ram, but make sure it's the same speed brand as the 2 1gb sticks, for 6gb total goodness, this is the memory you want, enjoy.http://www.newegg.com/Product/Product.aspx?Item=N82E16820220269
Thanks for the advice! So, it has to be the same brand? Didn't know that.
I've read some things about the yellow or black slot...
Do you know anything about that? Put the more powerful sticks in the yellow? Weak in the black?
