How to buy Laptop Memory (RAM)

leave a comment »

No matter what you use your laptop or desktop computer for, it can usually benefit from additional memory.  The more RAM memory you have in your computer, the easier it is to have multiple applications running at once, meaning your computer does not have to use the pagefile on your hard disk as much, so your computer runs faster and better.

So once you have decided to upgrade your RAM, your next decisions are,

– How much RAM do I need?

– What type of RAM do I need?

How much RAM you can upgrade depends on how many spare memory slots you have and how much RAM can go in each memory slot.  I usually open up a computer and see how many slots it has and how many are free.  But the amount and type of RAM that can go in each slot depends on the exact make and model of the computer or motherboard. Its best to have a look on manufacturer website for your computer or laptop specifications.

For example you will have DDR2 PC2-5300 that is inside of your laptop. In this case, DDR2 is the type of memory.  It refers to the memory technology, but importantly, it also indicates the size and shape of memory stick that will fit in your laptop.

PC2-5300 is a measure of the speed of memory that can be used in the laptop.  Some computers can make use of a couple of different memory speeds, and faster is generally better, but it is a good tip to make sure all of your memory sticks are running at the same speed, to make sure they are fully compatible with each other and to get the best performance out of them.

So if I only had 2 x 512MB RAM sticks in my laptop and I wanted to max out the memory, I would buy two sticks of 2GB RAM, remove the smaller memory sticks that the laptop came with, and install the new ones.  Job done.
