Does RAM affect FPS? If you’ve ever built a gaming PC or tried to squeeze a few more frames per second (FPS) out of your setup, you’ve probably asked yourself this question.
RAM (Random Access Memory) is one of the key components of a computer, but its relationship with gaming performance isn’t always straightforward.
Some people believe that adding more RAM instantly boosts FPS, while others think that RAM has nothing to do with it. So, what’s the truth?
In this article, we’ll break down how RAM works, how it affects FPS in online gaming, and how much RAM you actually need for a smooth gaming experience. Plus, we’ll give you some tips on choosing the right RAM for your gaming PC.
What is RAM?
RAM, or Random Access Memory, is the short-term memory of your computer. It temporarily stores data that your CPU needs to access quickly, allowing your system to run smoothly.
Unlike your hard drive or SSD, RAM doesn’t store data permanently—it clears out whenever you shut down your PC.
When you play a game, your computer loads essential game data into RAM so it can be accessed quickly.
This includes textures, character models, environments, and even in-game physics calculations. The more RAM you have, the more data your system can store in memory, which can help with performance—up to a certain point.
So, Does RAM Affect FPS? How?
Yes, RAM does affect FPS, but not in the way that a faster GPU or CPU does. RAM influences gaming performance in two major ways:
Preventing Bottlenecks
If your system doesn’t have enough RAM to handle a game’s demands, it will start using your storage (HDD or SSD) as virtual memory.
This process, called “paging,” is much slower than RAM and can lead to stuttering, lag, and lower FPS. In online gaming, this can be especially frustrating since lag can ruin your experience.
Allowing Smoother Multitasking
Many modern games require a lot of RAM, especially if you have other programs running in the background, like Discord, streaming software, or a web browser. With enough RAM, your PC can handle all these tasks without impacting FPS.
However, once you have enough RAM for a game to run smoothly, adding more won’t significantly increase FPS. The real performance gains come from upgrading your GPU or CPU.
If I Buy More RAM, Can it Increase FPS?
It depends on your current RAM situation. Here’s a general rule:
- If you have too little RAM (e.g., 4GB or 8GB in some modern games), adding more will likely improve FPS.
- If you already have enough RAM (e.g., 16GB for most games), upgrading to 32GB or more won’t make a big difference in FPS.
In online games, having extra RAM can help in specific scenarios, such as reducing stutters in large open-world games or improving responsiveness in fast-paced shooters.
But once you reach the recommended RAM for a game, FPS gains from additional RAM are minimal.
How Much RAM Memory Do You Need for Gaming?
The amount of RAM you need depends on the games you play and how you use your PC. Here’s a breakdown of RAM requirements for different gaming scenarios:
- 4GB RAM: Not recommended for gaming in 2025. Most modern games won’t even launch or will run at unplayable frame rates.
- 8GB RAM: The absolute minimum for gaming. Some older games and less demanding titles (like indie games) can run fine, but expect frequent stuttering in modern games.
- 16GB RAM: The sweet spot for gaming in 2025. Almost all games, including online multiplayer titles like Warzone, Fortnite, and Apex Legends, run smoothly with 16GB of RAM.
- 32GB RAM: Useful for gamers who also stream, edit videos, or run many background applications while gaming. Some newer AAA titles are starting to benefit from 32GB, but for most gamers, it’s overkill.
- 64GB+ RAM: Mostly unnecessary unless you’re doing professional work like 3D rendering, game development, or heavy video editing.
For online gaming, 16GB is generally the best choice. It allows you to run games smoothly while keeping essential background apps open.
How to Choose RAM for Your Gaming PC
If you’re looking to upgrade or build a gaming PC, choosing the right RAM isn’t just about the amount—it’s also about speed, latency, and compatibility. Here’s what to consider:
1. RAM Speed (MHz)
RAM speed is measured in megahertz (MHz), and higher speeds can improve performance in certain games. For gaming, aim for at least 3200MHz or higher, especially if you have a modern Intel or AMD processor. Faster RAM can make a noticeable difference in some CPU-heavy games, like strategy or simulation titles.
2. Latency (CAS Latency or CL)
CAS Latency (CL) refers to the delay between your RAM receiving a command and executing it. Lower latency is better, so try to get a balance between speed and CL (e.g., 3200MHz CL16 or 3600MHz CL18).
3. Dual-Channel vs. Single-Channel
Always use dual-channel RAM instead of a single stick. For example, 2x8GB (16GB) is better than a single 16GB stick. Dual-channel memory increases bandwidth and can improve gaming performance.
4. DDR4 vs. DDR5
- DDR4: Still the most common RAM type and offers excellent performance for gaming.
- DDR5: The latest generation with faster speeds and lower power consumption. If you have a newer motherboard that supports DDR5, it’s a good future-proofing option, but DDR4 is still a great choice in 2025.

5. Compatibility with Your Motherboard and CPU
Before buying RAM, check your motherboard’s supported RAM type, speed, and maximum capacity. Some motherboards may not support extremely high-speed RAM without manual adjustments in the BIOS.
So, does RAM affect FPS? The short answer is yes, but only to a certain extent. If you don’t have enough RAM, your FPS can drop due to stuttering and slow loading times.
But if you already have enough RAM for your game, upgrading won’t give you a massive FPS boost.
For online gaming, 16GB of RAM is the best choice for most players. If you stream, create content, or play highly demanding games, 32GB might be worth considering. When upgrading RAM, focus not just on capacity but also on speed, latency, and dual-channel configuration for the best performance.
At the end of the day, a balanced gaming PC—where the RAM, CPU, and GPU work well together—is the key to getting the best FPS. If you’re still experiencing low FPS, consider upgrading your GPU or CPU rather than just adding more RAM.
