Buying memory advice needed

[Janis]

I picked up a Inspiron 6000 at a yard sale and surprisingly  it is quite clean and in good operation.  However it has too little RAM and needs a larger hard drive.   I want to buy the RAM first and I found PC5300 and PC6400 listed for this laptop.  Does it make a big difference which I buy?   Should I buy two identical sticks per capacitiy or would one 1G and a 512 work?

NOTE: To get maximum performance\dual-channel memory bandwidth capability, both memory module connectors must contain memory modules and the modules must be of the same size and configuration.

Thanks for the info;  I always want to be certain of what to buy.   The laptop has XP Pro on it.
