- RAM vs CPU/GPU overclocking for gaming
- How much FPS increase you can expect from RAM overclocking
- The best RAM speeds for gaming
- Safely overclocking your RAM step-by-step
- Expert RAM recommendations for overclocking
- When RAM overclocking is, and isn‘t, worth it
By the end, you‘ll understand exactly how RAM impacts gaming FPS, whether overclocking it is worthwhile for you, and how high to push your memory if you decide to overclock. Time to turbo-charge your RAM!
How RAM Speed Affects Gaming FPS
Faster RAM can increase FPS by allowing quicker communication between your memory and CPU. But how exactly does RAM impact gaming performance, and why doesn‘t it affect FPS more?
RAM Speed Vs. Bandwidth
RAM speed is measured in megahertz (MHz), such as DDR4-3200 or DDR4-3600. This spec indicates how many million memory transfer operations can occur per second. Faster MHz = higher bandwidth between RAM and CPU.
Higher bandwidth can improve FPS in certain ways:
-
Faster load times: Games load textures, maps, and other assets from storage into RAM when loading. Faster RAM reduces load screen times.
-
Better min/max FPS: The CPU has quicker access to cached data needed to process each frame, improving minimum and maximum frame rates.
-
Smoother gameplay: Faster RAM improves 1% and 0.1% low FPS percentiles, reducing stuttering caused by intermittent frame time spikes.
Latency Matters Too
The CL (CAS Latency) timing is also crucial. This indicates the number of clock cycles it takes for RAM to respond to a CPU request. Lower = faster response and data access. Pay attention to RAM latency, not just raw speed!
Why RAM Has Less Impact Than CPU/GPU
Gaming involves a complex pipeline between your CPU, GPU, and RAM. The slowest link in this chain determines overall performance. For most games, the GPU handles majority of the work, while RAM acts as a high-speed cache.
Think of system memory like short-term storage. It‘s much smaller, but faster to access than VRAM or drives. Data needed immediately is loaded into RAM, ready for the CPU/GPU to process.
Faster RAM reduces latency fetching this data. But the CPU and GPU still play larger roles in actually transforming each frame. Especially at lower resolutions, the GPU limits performance more than RAM.
That‘s why overclocking your graphics card or CPU often yields bigger FPS gains. But RAM certainly isn‘t irrelevant – optimizing its speed can provide small improvements.
RAM Overclocking vs CPU/GPU Overclocking
Which should you overclock for the biggest increase in gaming FPS? Let‘s compare RAM overclocking against overclocking your CPU or GPU:
| Comparison | RAM Overclock | CPU Overclock | GPU Overclock |
|---|---|---|---|
| Typical FPS gain | 2-5% | 5-20% | 10-25% |
| Cost to overclock | $0 | $20-50 cooler | $0 |
| Risk of instability | Low | Moderate | Moderate |
| Difficulty | Easy | Moderate | Moderate |
As you can see, overclocking your graphics card or processor will yield much larger FPS improvements in most gaming scenarios.
However, RAM overclocking costs nothing extra and carries little risk. CPU/GPU overclocking requires decent cooling and careful tuning to avoid crashes or other issues.
For maximum FPS, overclock your GPU first, then CPU, then RAM. Think of RAM as the icing on top of the cake. Tweaking it should be the last step in optimizing gaming performance.
How Much Extra FPS Can You Get?
So just how much extra FPS can you expect from overclocking your RAM? The exact gaming FPS increase depends on your specific hardware, but here are some averages:
| RAM Speed | Avg FPS Increase |
|---|---|
| 2400 MHz -> 2666 MHz | 1-3% |
| 2666 MHz -> 3000 MHz | 1-5% |
| 3000 MHz -> 3200 MHz | 2-5% |
| 3200 MHz -> 3600 MHz | 3-7% |
| 3600 MHz -> 4000 MHz | 2-5% |
| 4000 MHz -> 4400 MHz | 1-3% |
As you can see, the FPS boost diminishes significantly past DDR4-3600. And these are averages across many games – the gains in any single title may be smaller.
The key takeaway? Don‘t expect miracle FPS increases from RAM overclocking alone. But combined with overclocking your CPU and GPU, every little bit counts towards higher performance!
Recommended RAM Speeds For Gaming
Given diminishing returns beyond a point, what RAM speeds deliver the best balance of cost and performance?
For modern gaming systems, DDR4-3200 CL16 is considered the sweet spot. It offers nearly optimal bandwidth for most games while avoiding the premium prices of higher speed RAM.
However, if building a maxed out high-end system, especially for 1440p or 4K gaming, springing for DDR4-3600 CL16 RAM can provide slightly better frame rates and 1% lows.
Here are my general recommendations if gaming is your main usage:
| Resolution | Recommended RAM | Notes |
|---|---|---|
| 1080p | DDR4-3200 CL16 | The GPU limits performance more than RAM at 1080p. No need to overspend here. |
| 1440p | DDR4-3600 CL16 | Faster RAM helps reduce stutters and squeeze out extra performance at higher resolutions. |
| 4K | DDR4-3600 CL16 | Go even higher if your budget allows, up to DDR4-4000 for high end 4K gaming. |
Of course, these are just general guidelines – feel free to experiment! The key is choosing RAM that matches the capabilities of your CPU and motherboard without overspending.
Now let‘s move on to actually overclocking RAM for even more speed…
Step-By-Step Guide to Overclocking RAM
Want to push your RAM past its rated speed for extra performance? Here‘s my detailed guide to safely overclocking RAM:
1. Enable XMP in BIOS
XMP (Extreme Memory Profile) automatically loads the high-speed timings and voltages tested to work with your RAM kit. This is technically a mild RAM overclock.
- Enter BIOS during boot by pressing Delete, F2, or other key depending on motherboard.
- Find the XMP or DOCP settings. This may be under overclocking or advanced menus.
- Choose Profile 1 to enable XMP. Save and exit BIOS.
Enabling XMP is the easiest first step to overclocking. Now let‘s tune things further.
2. Increment RAM Frequency
Increase RAM speed in 100 MHz increments testing stability each time:
- Re-enter BIOS and find the RAM frequency option.
- Raise frequency by 100 MHz, e.g. from 3600 MHz to 3700 MHz.
- Run stress tests like AIDA64 to check for errors.
- If stable, increase by another 100 MHz and retest.
Take this slowly, testing each step. Don‘t jump by more than 100-200 MHz at once or system may crash.
3. Stress Test and Tweak Timings
Use tools like MemTest86 to thoroughly test RAM overclock stability. If you get errors, try loosening timings or increasing voltage slightly if temperatures allow. The goal is the maximum stable frequency.
4. Monitor Temperatures
Check RAM temperatures using HWInfo or other hardware monitors. Overclocked DDR4 shouldn‘t exceed 45-50°C for optimal stability. Ensure your case cooling is adequate.
And that‘s it! With patience and small steps, you can tune your system memory to its peak gaming performance.
Best RAM For Overclocking
If you want plenty of overclocking headroom, choose RAM kits with higher XMP speed ratings. Here are my top recommendations as an overclocking enthusiast:
| RAM Kit | Speed | Notes |
|---|---|---|
| G.Skill Trident Z Neo | DDR4-3600 | Low latency and reliable overclocker. My current favorite DDR4 kit. |
| Corsair Dominator Platinum | DDR4-3600 | Looks great, overclocks well. On the expensive side. |
| HyperX Predator | DDR4-4000 | Excellent for pushing limits on high end systems. |
| Team Group Xtreem ARGB | DDR4-3600 | Good value with decent overclock potential. |
I suggest DDR4-3600 or DDR4-4000 kits for those serious about overclocking. But remember that results vary – there are always duds due to the silicon lottery. Do your research and buy from retailers with good return policies just in case.
When is RAM Overclocking Worth It?
So should you overclock your RAM or not for gaming? Here are my recommendations:
✅ YES if you already have a high end system and game at 1440p or 4K resolution. Faster tuned RAM can provide noticeable smoother gameplay.
✅ YES if you enjoy overclocking as a hobby and want to maximize every bit of performance. Consider it a fun challenge!
❌ NO if you game at 1080p. Focus on GPU/CPU overclocking first for bigger improvement.
❌ NO if you have a moderate or budget build. The small FPS boost isn‘t worth potential instability issues.
❌ NO if you value plug-and-play simplicity. The effort to overclock RAM may not be worth it for minimal gains.
For most mainstream gamers, I don‘t think RAM overclocking is mandatory. But on high-end systems where the GPU and CPU are already maxed out, tuning your RAM can help unleash a few extra frames.
Just temper your expectations – RAM overclocking alone won‘t transform gaming performance. But combined with other optimizations, every bit helps!
