What is Overclocking?
Overclocking is the process of increasing your CPU’s clock speed beyond its factory-set limit to boost performance. The faster your CPU cycles, the more tasks it can handle per second, resulting in higher FPS in games, faster rendering times, and snappier performance in demanding applications.
Why Do People Overclock?
- Gamers want more FPS for smoother gameplay.
- Content creators need faster rendering for videos and 3D modeling.
- AI researchers and data scientists require quicker computation times.
- Tech enthusiasts enjoy pushing hardware to its limits.
| Pros of Overclocking | Cons of Overclocking |
|---|---|
| Higher performance in games & software | Increased heat and power consumption |
| Better multitasking and responsiveness | Can void warranty if done incorrectly |
| Maximizes the potential of your CPU | Risk of system crashes and instability |
| Great for heavy workloads like video editing | Requires better cooling solutions |
What is Underclocking?
Underclocking is the opposite of overclocking—it reduces the CPU’s clock speed to save power, reduce heat, and increase longevity.
Why Do People Underclock?
- Laptop users want longer battery life.
- Silent PC builders aim for lower heat and fan noise.
- Servers run more efficiently with controlled temperatures.
- Eco-conscious users want to reduce energy consumption.
| Pros of Underclocking | Cons of Underclocking |
|---|---|
| Lower power consumption and longer battery life | Reduced performance in demanding tasks |
| Decreases heat, leading to quieter operation | May slow down games and heavy software |
| Extends hardware lifespan | Not beneficial for power users |

Underclocking in 2025: A Growing Trend?
With rising energy costs and a focus on sustainability, underclocking is more relevant than ever. Modern CPUs now feature Dynamic Clock Adjustment, where AI automatically adjusts power and clock speed based on real-time needs.
- Apple’s M-Series chips dynamically adjust power draw for efficiency.
- AMD’s Ryzen AI enables smart underclocking in laptops.
- Intel’s Power Efficiency Mode reduces thermal output in ultra-thin devices.
Is Underclocking Right for You?
If you use your device primarily for browsing, office work, and media consumption, underclocking can greatly improve battery life and system longevity.
How to Overclock Your CPU Safely
Step 1: Check Compatibility
Ensure your CPU and motherboard support overclocking.
- Intel CPUs: Look for “K” series (e.g., i7-13700K)
- AMD CPUs: Most Ryzen models support overclocking.
Step 2: Adjust BIOS/UEFI Settings
- Enter BIOS by pressing DEL or F2 at startup.
- Locate the Overclocking Settings.
- Increase clock speed in small increments (e.g., +100MHz).
- Adjust voltage carefully to maintain stability.
Step 3: Stability Testing
Use benchmarking tools like:
- Cinebench R23 (CPU stress test)
- AIDA64 (thermal monitoring)
- Prime95 (extreme load testing)
How to Underclock Your CPU for Efficiency
Method 1: Use Power Management Settings
- Open Windows Power Plan Settings.
- Set Maximum Processor State to 80-90%.
- Save changes to reduce power consumption.
Method 2: Use Software Tools
- Intel XTU: For adjusting voltages and clock speeds.
- ThrottleStop: Ideal for undervolting laptops.
- AMD Ryzen Master: Provides fine-tuned underclocking.
Overclocking vs. Undervolting: Are They the Same?
Many confuse undervolting with underclocking. Here’s a quick comparison:
| Feature | Overclocking | Undervolting |
|---|---|---|
| Goal | Increase performance | Reduce power usage without lowering clock speed |
| Method | Raise clock speed & voltage | Lower voltage while maintaining clock speed |
| Best for | Gamers, power users | Laptop users, silent PCs |
The Future of CPU Performance Tuning
Looking ahead, we see AI-powered optimizations, chiplet architectures, and ARM-based efficiency cores shaping CPU tuning.
- Will manual overclocking become obsolete? Possibly!
- Will underclocking become more automated? Definitely!
Modern CPUs will likely self-optimize based on user behavior, making traditional overclocking and underclocking less necessary.

FAQs
Is overclocking still worth it in 2025?
Yes, but it depends on your use case. With AI-assisted performance tuning and efficient cooling solutions, modern CPUs already optimize themselves well. However, for gamers, content creators, and power users, manual overclocking can still provide extra performance gains.
Can overclocking damage my CPU?
If done improperly, yes. Overclocking increases heat and power consumption, which can lead to system instability and shortened CPU lifespan if not properly cooled. However, modern motherboards and CPUs have built-in safeguards to prevent extreme damage.
Do I need liquid cooling for overclocking?
Not necessarily. High-end air coolers can handle moderate overclocking. However, for extreme overclocking, liquid cooling (AIO or custom loops) is recommended to maintain lower temperatures and stability.
What’s the difference between undervolting and underclocking?
Underclocking reduces clock speed to save power and reduce heat.
Undervolting reduces voltage while maintaining clock speed, lowering power consumption without sacrificing performance.
Undervolting is often preferred as it retains performance while improving efficiency.
Can underclocking improve battery life?
Yes! Underclocking reduces CPU power consumption, which can extend laptop battery life significantly, especially for tasks like web browsing and office work.
Will underclocking make my PC slower?
It depends. For basic tasks, you won’t notice much difference. But for gaming, video editing, or heavy multitasking, underclocking can reduce performance.
Does overclocking void my CPU warranty?
In most cases, yes. Intel and AMD state that manual overclocking voids warranties, though some brands offer “Overclocking Protection Plans” for an additional fee.
How do I check if my CPU is overclocked?
You can check using tools like:
CPU-Z – Displays clock speed in real-time.
Task Manager (Windows) – Under “Performance” tab, check clock speed.
BIOS/UEFI – Shows CPU frequency settings.
Can I overclock a locked CPU?
No. Intel’s non-K series CPUs and some AMD CPUs have locked multipliers, meaning they cannot be overclocked. However, you can sometimes tweak performance via BCLK adjustments or PBO (Precision Boost Overdrive) for AMD CPUs.
Does underclocking reduce heat and fan noise?
Yes! By lowering clock speeds and voltage, your CPU generates less heat, allowing fans to run quieter. This is ideal for silent PC builds.
Should I overclock my CPU for gaming?
If your GPU is the bottleneck, overclocking the CPU won’t make much difference. However, in CPU-intensive games like strategy games, simulation games, and high-FPS shooters, overclocking can help.
What are the best tools for overclocking and underclocking?
For Overclocking:
BIOS/UEFI (Manual overclocking)
Intel XTU (Intel CPUs)
AMD Ryzen Master (AMD CPUs)
MSI Afterburner (For GPU overclocking)
For Underclocking:
Windows Power Management (Adjust CPU max power)
ThrottleStop (Intel laptops)
AMD Ryzen Master (AMD CPUs)
Will future CPUs eliminate the need for manual overclocking?
With AI-driven performance tuning, manual overclocking is becoming less necessary. However, enthusiasts and power users will still benefit from fine-tuning their hardware manually for maximum control.
