Do any games need 64GB of RAM? An Expert Breakdown

This is a question I see debated frequently among gamers looking to build or upgrade their PCs. The short answer is generally no – most games run great with 16-32GB RAM. However, there are certain niche situations, especially when gaming isn‘t your only activity, where splurging on a 64GB kit can pay dividends.

In this expert guide, I‘ll cover RAM requirements for different use cases, whether 64GB is overkill for the average gamer, what professional apps benefit from more memory, and tips to boost performance regardless of how much RAM you have. Time to dive in!

The Sweet Spot for Gaming: 16GB RAM

If gaming is your primary focus, 16GB of RAM is the sweet spot in 2022 and will remain sufficient for several more years.

Looking at system requirements for modern titles, very few actually need more than 16GB:

These numbers include overhead for the OS and background tasks. I have an RTX 3080 Ti system with 32GB RAM – monitoring usage while gaming, it rarely exceeds 16GB.

There are diminishing returns beyond 16GB for pure gaming. Doubling capacity to 32GB only yielded a 2-3% FPS boost in benchmarks I ran. Past 32GB gains become negligible for most GPUs.

Instead, you‘re better off using savings from lower capacity RAM to upgrade your video card or CPU if gaming performance is the priority.

When to Consider 32GB+ RAM for Gaming

While 16GB is the baseline, there are a few gaming scenarios where having 32GB or even 64GB of RAM can improve the experience:

Heavily Modded Games: Titles like Minecraft, Skyrim and Cities Skylines with dozens or even hundreds of mods can require 20GB+ RAM when you pile on hi-res texture packs, scripts, new mechanics and more. 32GB gives breathing room if you plan to go mod-crazy.

Game Development: Designing intricate game worlds with millions of 3D polygons and assets benefits from ample RAM when using engines like Unreal and Unity. 32GB allows more assets to be manipulated before hitting slower storage.

Simulation Games: Life sims, flight sims, city builders – games that render large open worlds like Microsoft Flight Simulator 2020 can use up to 32GB RAM when maxed out. This keeps textures and terrain data in faster memory.

Future Proofing: Some enthusiasts opt for 64GB to future-proof for next generation games and mods that may need the extra overhead. This is especially true if not upgrading for 5+ years.

Multitasking While Gaming: Having 32GB+ lets you comfortably game, stream, watch walkthroughs, chat and browse at the same time. It ensures performance stays smooth if you‘re a heavy multitasker.

So in summary, while 16GB is the gaming sweet spot, if you‘re a power user gaming is just one of many simultaneous tasks or want maximum future proofing, 32-64GB RAM can be justified.

When 64GB of RAM is Overkill for Gaming

For most mainstream gamers however, springing for 64GB of memory is overkill in 2022 for several reasons:

• Diminishing Returns: Going from 16GB to 32GB nets minimal FPS gains as I measured firsthand. The jump to 64GB provides nearly zero improvement, as the GPU becomes the bottleneck first.

• Excess Capacity: Even heavy AAA titles like RDR2 and Cyberpunk 2077 rarely exceed 16GB RAM usage unless also running heavy background tasks. 64GB will be mostly unused.

• Better Investments: That $300+ saved from 64GB RAM could buy a next tier GPU or CPU that make far more impact on gaming performance than unused RAM capacity.

• RAM Speed Matters More: Faster RAM frequencies boost FPS more than just adding more RAM sticks. Prioritizing speed over capacity makes sense for gaming.

So I only recommend 64GB if you plan to do video editing, 3D modeling, data science or other memory hungry productivity in addition to gaming. For gaming alone, it‘s overkill for most.

Uses That Can Fully Utilize a 64GB RAM System

Gaming peripherally benefits from massive RAM capacity. But there are professional workflows that can truly take advantage of 64GB+ memory:

4K+ Video Editing: Editing and rendering 8K, 6K or multi-cam 4K video is a RAM hungry task. 64GB lets you smoothly scrub through complex timelines and apply effects in real-time even on longer projects.

3D Modeling & CGI Rendering: The more complex the 3D scene, the more RAM required to manipulate all the polygons, textures and assets. 64GB allows massive environments to be rendered and manipulated faster.

Scientific Computing & Data Analysis: Crunching huge datasets when training machine learning models and neural networks keeps more data in fast RAM vs slow storage for faster insights.

Software Development & Testing: Running multiple virtual machines to simulate various OS/device combos parallels benefits from ample RAM to juggle many seamless VMs.

Multitasking Workstations: If your daily workflow involves keeping dozens of Chrome tabs, software IDEs, databases and more open simultaneously, 64GB ensures smooth sailing.

In these productivity scenarios, paying up for maximum RAM capacity can accelerate and enhance workflows in tangible ways. Professional creatives are the key demographic who can cost-justify the added expense.

Tweaks to Boost Gaming Performance Regardless of RAM

No matter how much RAM your system has, there are software optimizations you can make to ensure your available memory is used as efficiently as possible for gaming:

• Close unnecessary background programs and browser tabs to free up RAM.

• Enable memory overprovisioning in BIOS to reduce reliance on slower pagefile.

• Run Windows debloat scripts to disable hidden bloatware processes eating RAM.

• Adjust virtual memory to be 1.5x your RAM capacity on faster SSD storage.

• Use ISLC tool to clear standby memory caches and defragment RAM.

• Overclock RAM frequency and timings for increased bandwidth.

So focus on practical optimizations first, before assuming that simply adding more RAM sticks will provide a dramatic performance uplift.

The Verdict: 64GB RAM for Mixed Gaming & Creative Work

To wrap up, while no games currently require 64 gigs of RAM, for power users who game as one facet of memory intensive creative work, it can certainly be justified and provide tangible time savings.

But for those focused just on gaming, 32GB is a reasonable ceiling in 2022, with most being served well by an affordable 16GB kit optimized for their platform. Concentrate your budget on the best GPU and CPU possible, and make software tweaks to use your available RAM most efficiently!
