What Is RAM and What Does It Do?
RAM (Random Access Memory) is a temporary storage space that your system uses to store and quickly access data needed to run applications and games. Unlike your SSD or HDD, RAM is much faster but doesn't retain data when your system shuts down.
In gaming, RAM:
Holds textures, maps, and assets while you play
Allows for smooth switching between game and other apps
Impacts load times and in-game responsiveness
However, RAM is just one part of a complex performance puzzle, alongside your CPU, GPU, and storage.
Myth 1: More RAM Always Means Better Gaming Performance
❌ The Myth:
"Upgrading to 32GB or 64GB of RAM will instantly boost FPS and performance."
✅ The Reality:
More RAM helps—up to a point. Most modern games run perfectly with 16GB of RAM, and anything beyond that often shows no significant performance improvement unless you’re multitasking heavily or using RAM-hungry applications in the background.
In benchmarks, jumping from 8GB to 16GB often provides a noticeable performance boost. However, going from 16GB to 32GB in gaming shows minimal to no FPS gains unless:
You’re streaming gameplay
Running virtual machines
Using mods with large texture packs
Reality Check: How Much RAM Do You Actually Need for Gaming?
Here’s a quick breakdown based on gaming needs:
So, while more RAM might sound future-proof, you’ll often be better off investing in a stronger GPU or faster SSD.
Myth 2: RAM Speed Has No Effect on Gaming
❌ The Myth:
"Only GPU and CPU speed matter. RAM frequency doesn’t affect games."
✅ The Reality:
RAM speed can affect gaming—but the degree depends on the game and CPU architecture. Faster RAM means your system can send and receive data quicker, which benefits games that rely heavily on CPU performance or use integrated graphics.
For example:
APUs (like AMD Ryzen with Vega Graphics) benefit greatly from faster RAM
Competitive games like CS:GO or Valorant may see small FPS gains with higher RAM speeds (e.g., 3000MHz vs 3600MHz)
Games that load large worlds or rely on real-time data (like Microsoft Flight Simulator) can benefit marginally
Important Note: Faster RAM often has diminishing returns. You may see a 5–10% FPS boost going from 2666MHz to 3600MHz, but little improvement beyond that.
Reality: RAM Speed and Latency Matter—But Not Always Equally
Key Factors:
Frequency (MHz): Higher frequency = faster data transfer
CAS Latency (CL): Lower is better; measures delay between commands
The ideal combo for gaming is high frequency + low latency (e.g., 3600MHz CL16). However, most gamers won’t notice the difference between 3200MHz CL16 and 3600MHz CL18 in real-world use.
Myth 3: Dual-Channel vs Single-Channel RAM Doesn’t Matter
❌ The Myth:
"Using one stick or two makes no difference—it's all the same."
✅ The Reality:
Dual-channel RAM configurations provide significantly better performance than single-channel setups, especially for gaming.
Why Dual-Channel Is Better:
Offers twice the bandwidth for memory operations
Reduces bottlenecks between RAM and CPU
Improves FPS in memory-sensitive games (e.g., open-world titles)
Real-World Impact:
In games like Far Cry 5 or Shadow of the Tomb Raider, dual-channel configurations have shown up to 10–20% FPS improvements over single-channel.
Pro Tip: Always install RAM sticks in the correct slots (usually 2 & 4) to enable dual-channel mode.
Myth 4: 32GB or More Is Essential for Gaming
❌ The Myth:
"Modern games need at least 32GB to run smoothly."
✅ The Reality:
Most games—even modern AAA titles—do not require more than 16GB. RAM usage in popular titles:
32GB is useful if you’re also:
Streaming while gaming
Running multiple Chrome tabs, Discord, OBS, and editing software
Using large texture mods
Otherwise, 32GB is more of a luxury than a necessity.
Reality: Overkill RAM Offers Diminishing Returns
Gamers chasing high FPS will benefit more from GPU and CPU upgrades than simply maxing out their RAM. It’s better to strike a balanced build than overspending on excess memory.
Example:
A gamer upgrading from 16GB to 32GB may gain 0–5 FPS in most titles. But upgrading from an RTX 3060 to an RTX 4070 can yield 30–60 FPS increases.
How RAM Affects Popular Games
Let’s take a closer look at how RAM influences real-world game performance:
Cyberpunk 2077
8GB RAM: Frequent stuttering, long load times
16GB RAM: Smooth experience on high settings
32GB RAM: Helps when modding or multitasking
GTA V (Modded)
Vanilla: 8GB sufficient
Modded: Can use up to 20GB
Call of Duty: Warzone
16GB recommended
32GB useful for background apps
Microsoft Flight Simulator
RAM-intensive; 32GB may help with stutter-free 4K performance
How to Optimize RAM for Gaming
If you're not ready to upgrade, here are tips to make the most of your current RAM:
1. Close Background Programs
Apps like Chrome, Discord, and Steam overlays can eat up RAM.
2. Enable XMP/DOCP in BIOS
Unlocks full RAM speed instead of default 2133MHz or 2400MHz.
3. Use Dual-Channel Setup
Even if you only have 8GB, two 4GB sticks are better than one.
4. Tweak Virtual Memory
On systems with low RAM, increasing page file size may help reduce stutters.
5. Update Your BIOS
Ensures your motherboard fully supports RAM compatibility and performance.
Final Thoughts: Smart RAM Choices for Gamers
Upgrading or optimizing RAM is an effective way to improve gaming performance—but only when it’s truly the bottleneck. Here's a quick recap:
Myths Busted:
✅ More RAM isn't always better
✅ RAM speed and configuration can affect performance
✅ 32GB+ is not a requirement for most gamers
✅ Dual-channel setups do make a difference
Real Recommendations:
Aim for 16GB DDR4 or DDR5, 3200–3600MHz for most gamers
Use dual-channel (2x8GB)
Enable XMP profiles for max speed
Upgrade to 32GB only if you stream, mod, or multitask heavily
Investing in balanced RAM—not just more RAM—is the real key to unlocking your gaming PC's full potential.
