How can I upgrade my ram 2gb to 4gb

first and foremost find out what type of ram your computer is compatible with. just look up what type of ram your computer takes and whaat is the maximum amount of ram it can use. after that it is just a matter of swapping the ram cards out and making sure your securely put the new ones in. I do not have a tutorial on how to do this but that is the first step is to find out what type of ram the computer can take. it would suck to get new ram put it in your computer and then have it not work. i hope that this helps some and i am pretty sure that someone will post a tutorial soon on how to do this.

I also own asus x200ma, as far as i know, the ram is onboard. So there's no ways to upgrade it beside changing the mainboard. My suggestion would be to upgrade it with an SSD. It helps with the overall performance. Cheers. jualhondajakarta
