RAM

How much RAM do I need?

6 min read

It's one of the most frequent questions when building a PC, and the short answer is: probably less than you think, but more than the bare minimum. The ideal amount of RAM depends on what you'll do with your build. Here it is broken down into concrete numbers.

What RAM does, in one sentence

RAM is your PC's temporary working memory: it's where everything you have "open" at the moment lives — the game, the browser with its tabs, your programs. The more RAM you have, the more things your PC can handle at once without slowing down. If you run short, the PC starts stuttering because there isn't enough room for everything.

The amounts, based on what you do

Today, in 2026, these are the tiers that make sense:

• 8 GB: falls short for gaming. Fine for basic tasks (browsing, office work), but in many current games you'll already feel the limit. We don't recommend it for a new gaming PC.
• 16 GB: the comfortable minimum for gaming today. Runs the vast majority of current games without issues. If your budget is tight, it's a perfectly valid starting point.
• 32 GB: the sweet spot. Gives you margin for demanding games, lots of tabs and programs open at once, and some light content creation. It's the amount we recommend for most people building a PC meant to last.
• 64 GB or more: only makes sense if you also do heavy work besides gaming — 4K video editing, 3D modeling, virtual machines, or local AI. For gaming and nothing else, it's money that would go much further on the graphics card.

The detail many people overlook: using two sticks

Here's a trick that improves performance for free. RAM works better "in pairs": it's better to buy, for example, two 16 GB sticks (2×16) than a single 32 GB stick. When there are two sticks, memory runs in what's called "dual channel," which gives a real performance boost, especially in games. That's why kits are usually sold in pairs. If you can choose, always go with two sticks instead of one.

Speed matters too (but don't obsess over it)

RAM has a speed rating, which you'll see as a number like "DDR5-6000." Faster is better, especially for current processors that make good use of memory speed. You don't need the fastest one on the market, but a decent speed (like DDR5-6000) is a good balance between price and performance. Getting the amount right matters more than chasing maximum speed.

A note on pricing

Worth knowing: in 2026, RAM is more expensive than usual due to the huge demand for memory from the AI industry. This makes "buying extra just in case" hurt your wallet more than it would in other times. Another reason to buy the amount you'll actually use, not the one that sounds impressive.

So, how much should I buy?

To sum up: if it's for gaming and your budget is tight, 16 GB. If you want comfort and longevity, 32 GB (the sweet spot for most people). Only go up to 64 GB if you genuinely do heavy creative work. And whenever you can, in two sticks.
