I am currently using 1gb ddr2 667mhz ram and having an idea of upgrading. can i buy a 2gb ddr2 and add to 1gb or i have remove 1gb before adding the 2gb.Does it cause any problem or damage to PC if we use uneven rams?

It is better to use simms with the same speed if possible, but that said you can use different speeds, it just means faster RAM will only run at the same speed as the slower.
