What Is RAM and How Much Do You Need?

RAM (random access memory) is the short-term workspace of your computer. Programs and files you are currently using are held there because RAM is far faster than permanent storage.

RAM is not storage

Storage (an SSD or hard drive) keeps your files when the computer is off. RAM is cleared when you shut down. A useful comparison is a desk (RAM) versus a filing cabinet (storage): a bigger desk lets you work on more things at once, but it does not store more documents.

How much do you need?

• 4 GB: only suitable for very light use, and often frustrating with modern software.
• 8 GB: fine for web browsing, office work and streaming.
• 16 GB: a comfortable choice for multitasking, many browser tabs, light photo editing and most games.
• 32 GB or more: useful for video editing, large projects, virtual machines and professional creative software.

Signs you may need more

• The computer slows down when you open several programs.
• The disk activity light stays busy because Windows is moving data to the page file.
• Task Manager shows memory use close to its limit during normal work.

Can you upgrade?

Most desktops allow it. Many modern thin laptops have soldered memory that cannot be changed, so check the specifications before you buy. If you upgrade, match the memory type (for example DDR4 or DDR5), and ideally install a matching pair for better performance.

Quick tip

Before buying more memory, open Task Manager (Ctrl + Shift + Esc) and look at the Performance tab while you work. If memory use is regularly high, an upgrade will help. If it is low, a different bottleneck is slowing you down.
