How much RAM for a gaming PC in 2025? The ultimate guide to choosing without making a mistake

The RAM (Random Access Memory) is a form of temporary memory that your PC uses to store the data it needs in the short term while you are using it. Unlike a hard drive or SSD, RAM is volatile, which means that everything it contains is erased as soon as you turn off your computer.

But while you play, it is the RAM that links the processor, your graphics card, and the rest of the system so that everything runs quickly and smoothly. When you launch a game, explore an open world, load a map, switch between tabs on Chrome while keeping OBS and Discord open, your RAM is constantly being used.

👉 The more RAM you have, the more space your system has to "breathe." And in the gaming world, having enough RAM often makes the difference between a smooth session and a struggle with stuttering, freezes, and never-ending loading times.

The question of the ideal quantity of gaming computer RAM depends largely on your actual usage. You don't play the same way if you launch LoL once a week or if you stream Baldur’s Gate III with mods and overlays every night. Here's a very clear comparison to help you assess your needs 👇

It's THE big question that everyone is asking: "16 GB of RAM is it enough to play?" And the answer is clear: yes, in 2025, 16 GB are still sufficient for a very large majority of players. You can run games like Elden Ring, Apex Legends, Fortnite, Cyberpunk 2077 or even modded GTA V without any major issues.

But be careful, this statement has its limits. If you're the type to launch your game while keeping YouTube, Discord, Spotify, Steam, Chrome (with 15 tabs open, of course), and OBS running in the background , then you may experience a lack of fluidity. And there, 16 GB will quickly be saturated. For more intensive use, especially in multitasking or streaming, It is clearly recommended that you upgrade to 32 GB of RAM.

There is a debate that regularly comes back in the community: " 16 or 32 GB of RAM for gaming? "Some will say that 16 GB is enough for all current games. Others will argue that you need 32 GB to "be safe" in the future. Here is a detailed comparison table to help you make your choice:."

When we talk about gaming desktop RAM , one must not only focus on the quantity. The quality of your RAM , that is to say its technical specifications, can also play a role in performance:

• Frequency (MHz): The higher the frequency, the faster the RAM can transfer data. In gaming, 3200 MHz is an excellent minimum, but if you want to maximize performance with an AMD Ryzen processor, 3600 MHz is often ideal.
• CAS Latency: The lower the CAS, the better. A 3200 MHz CL16 RAM will generally be more responsive than a 3200 MHz CL22.
• DDR4 vs DDR5: DDR5 is faster, but still quite expensive and useful especially if you have a very recent setup (Intel 13th gen or AMD Ryzen 7000). DDR4 remains an excellent value for money.

👉 We explain all this to you in our complete guide to gaming RAM 2025 .

You will often see bars labeled as "Gaming RAM" or "RAM gamer", with a stylish look, heat sinks, and RGB LEDs everywhere. But in terms of raw performance , a "gaming" stick and a "standard" stick of the same frequency and latency will do almost the same job.

The difference? The style, the cooling, and sometimes a bit of stability in overclocking. So if you want your setup to look like a monster and shine like a Christmas tree, go for gaming RAM. Otherwise, focus on the specs.

Good news: RAM is one of the simplest components to upgrade on a gaming PC You don't need to be a hardware expert to add RAM.

1. Check how many slots are available on your motherboard (usually 2 or 4).
2. Use CPU-Z or Speccy to know what you have already installed.
3. Choose a compatible kit (same type, same frequency if you add).
4. Turn off your PC, discharge yourself from static electricity, and install the RAM modules.
5. Restart. That's it.

And there you go, you just increased your PC's performance in less than 10 minutes. 🔥

→ Is 8GB of RAM enough for gaming?

Honestly, no. In 2025, 8 GB is outdated for gaming, even occasionally. You risk experiencing slowdowns as soon as you launch more than one software at a time.

Does RAM influence FPS?

Not directly, but if you don't have enough RAM, your PC swaps to the disk, which slows everything down. You lose fluidity and loading time.

Can I mix two different RAM kits?

It is possible, but not recommended. You risk instability or throttling to the lowest frequency.

Should I choose 2x16 GB or 4x8 GB?

Prefer 2x16 GB if your motherboard only has 4 slots, it leaves you room to add more later.

To summarize simply:

• 🎮 You play from time to time, without streaming → 16 GB is enough.
• 🚀 You play to the max, you stream, you open lots of apps at the same time → 32 GB bring you royal comfort.
• 🎥 You work in 4K, you do editing or 3D → 64 GB or more, but that's another world.

By 2025, the right compromise for a modern gamer, it's clearly 32 GB of RAM You will be comfortable with all games, even the most demanding ones, and you will see the difference in fluidity.
