Your computer has 1gb pc2 5300 ddr2 sdram expandable to 2gb what benefit will you get from expanding to 2gb is there a benefit to changing to pc2 6400 can you add 1 gb of 6400 to the existing 5300?

Answer

Basically your PC will be faster, 2 things affect the speeds of computers, CPU/Processor is raw power, RAM enables more things to be done at once, however because your computer is doing hundreds of things (in the background) even if your only writing a word doc, being able to do more things also increases the speed. 6400 runs at a faster MHz therefore the ram is faster than the 5300, however you shouldn't mix and match, RAM should always be in matched pairs if possible, your PC will probably run faster with 2 5300's rather then a 5400 and a 6400 (even though this would seem better).
