I have been looking at a lot of laptops recently and have a (possibly stupid) question about RAM.
I have noticed that a lot of the laptops (and computers in general I guess) come pre-configured with 1 GB of RAM (DDR2 667) in 2x 512MB sticks. Now, to me it would make sense to get 1 GB in 1 stick... so you would have room to upgrade later without having to get rid of RAM that you already paid for.... but since the 2x 512GB thing seems so common I was wondering if there was a performance related reason for this.
Will 2x 512MB out perform a 1 GB stick (again, DDR2 667)? If not, why do computers so commonly come equipped with 2x 512 instead of just having a 1GB stick when the difference in price is only a couple of dollars?
