Real newbie question I know, but I'm buying a new laptop and it comes with 2GB RAM included in the price. I already own two 1GB RAM chips so I was wondering if I could insert those into the new laptop to make a total of 4GB RAM. But then I thought it might only have 2 ports for inserting RAM, each port allowing either a 1GB chip or a 2GB chip (if such a thing exists).

The specs on the laptop say "Up to 4GB Dual Channel 667MHz DDR2 SDRAM" . Does this mean that there are only 2 RAM ports? And if so, can I still insert my own 1GB RAM chip to make 3GB ?

Thanks in advance.

Laptops normally only have two ram slots.
You could try one of the 1G ram but don't be surprised if it does not work as laptops can be very picky about what ram is used

Even the laptops with a max of 4 Gb RAM?

So you mean it probably only has two slots and it might only accept 2Gb RAM chips of a specific kind?

It might accept any capacity of a chip, but just certain kinds of let's say 512, 1 GB, 2 GB chips.

That sounds likely - my own 1GB chips are useless in that case. It will cost extra to get 3 or 4 gigs. I suppose it can't be helped.

Thanks for the replies.
