I was hoping to improve my amount of RAM. At the moment i have 512Mb and would like to upgrade this, if I was to buy 1Gb, could i use both at the same time (for 1.5Gb) or would I only be able to use 1 at a time.
I'm guessing i could buy another 512Mb and use that with my current one or buy 2 1Gb and use 2 of those together instead.
