Learn About Laptop Memory
Laptop memory quick guide
What is it?
Also known as random access memory (RAM). It is one of many types of memory in computers. RAM is a volatile memory, which means it will lose all stored data when power is turned off. It's main role is to store the operating system and currently active applications, so that the CPU can access them quickly to reduce the bottleneck from the much slower non-volatile memory. Think of it like your desk's surface. You get your files from the file cabinet (non-volatile memory). Then, you can only place a limited amount of open files or notebooks on your desk that you can work on. If your desk surface is bigger, you can place more files that you can work on. Similarly, if you have more RAM, then you can have more applications open at the same time.

Memory works by doing the following (over simplified) steps:
- Retrieves data from non-volatile memory
- Sends requested data to CPU
- Receives processed data from CPU
Look for
-
Upgradability
Check if the memory is upgradable
-
Compatibility
Check DDR type, speed, and slots
-
Get Enough
Make sure you have enough memory to run your applications at full speed
Check the requirements for your software. Today, the minimum should be 8GB, while 16GB can be the minimum if you are a heavy user (many tabs/apps open). Modern operating systems extend memory capacity by using your computer's slower non-volatile memory (Storage), this technique is known as "virtual memory". This can help in making sure your computer runs well even when you run out of memory. However, if your apps can take advantage of the full speed of memory, virtual memory will not help.

Future Proofing
Do not buy more memory than you need just for future proofing, if your laptop memory is upgradable
Memory is usually the easiest part to upgrade in laptops (if upgradable). Whenever you feel in need of more memory, you can simply add more by using any available slots, or removing old small memory modules and replacing with newer larger ones.

Higher Frequency
Do not get memory that is rated faster then your CPU can handle
Let's say you got memory running at 3600, but your CPU can only handle 2400, then your memory will run at 2400.
