Sure just make sure you have enough slots because they might have 2x 256MB sticks and only 2 slots if this is the case then you will have to buy 1x 1GB stick and dispose of the other two or you may find you have just 1x 512MB stick and one empty slot then you guessed it just stick in another 512 stick... just make sure you buy DDR PC2100.
Actually it is quite the opposite. The more RAM you have the more speed at which data can be transferred to the RAM. An example is if you have 512 Mb of RAM then 512 Mb of data will be transferred to the RAM at a time, but if you upgrade it to 1 GB of RAM then 1 GB of data will be transferred to the RAM at a time verses the 512 Mb. So the speed at which the RAM stores data will increase if the size of the RAM is increased. I hope this answers your question.
