How to Fix CPU Not Reaching Turbo Speed on Windows 11: Effective Troubleshooting Steps

If your CPU is not reaching its turbo speed on Windows 11, it can affect your computer’s performance. Turbo speed is the higher clock rate your CPU can achieve automatically for demanding tasks. When this feature doesn’t work properly, your system may feel slower than expected.

This guide will help you understand why your CPU might not be boosting to turbo speeds and provide simple, step-by-step troubleshooting methods.

Each step is explained in detail, so even if you’re new to PCs, you can follow along easily.

By the end, you’ll know how to check and fix common issues preventing your CPU from reaching its full potential.

Quick Note Before You Start

  • Ensure your computer supports turbo boost—most modern Intel and AMD CPUs do.
  • Make sure you are using the latest Windows 11 updates for optimal performance and compatibility.
  • Check that your PC’s cooling system (fans, heatsinks) is functioning well to prevent thermal throttling.
  • Have your PC plugged into power; some laptops reduce CPU speeds on battery to save energy.

Step 1: Verify CPU Turbo Boost is Enabled in BIOS/UEFI

The BIOS or UEFI firmware controls low-level hardware settings, including turbo boost. Sometimes, this feature might be disabled by default.

  1. Restart your PC and enter BIOS/UEFI settings. This usually involves pressing Delete, F2, or Esc key immediately after powering on (check your PC manual).
  2. Look for CPU settings or advanced CPU configuration menu.
  3. Find the option related to “Turbo Boost,” “Intel Turbo Boost Technology,” or “AMD Precision Boost.”
  4. If it’s disabled, enable it, then save and exit BIOS.

Why this matters: If turbo boost is turned off at firmware level, Windows cannot increase CPU clock speed beyond the base frequency.

Step 2: Check Windows Power Plan Settings

Windows controls CPU performance based on power plans that balance speed and energy usage. An aggressive power-saving plan might prevent turbo speeds.

  1. Open Settings by pressing Windows + I.
  2. Go to System > Power & battery > Power mode.
  3. Select Best performance or a similar high-performance option.
  4. Alternatively, open Control Panel > Power Options, and choose the High performance plan.

Why this matters: Power plans influence CPU behavior; selecting a high-performance plan allows the CPU to reach higher speeds.

Step 3: Adjust Advanced Power Settings for Maximum Processor State

Within power plans, the “Maximum processor state” setting controls how much CPU power is allowed.

  1. Open Control Panel and go to Power Options.
  2. Click on Change plan settings next to your selected power plan.
  3. Select Change advanced power settings.
  4. Expand Processor power management > Maximum processor state.
  5. Make sure this value is set to 100% for both “On battery” and “Plugged in” (especially for laptops).
  6. Click Apply and then OK.

Why this matters: If the maximum processor state is limited, your CPU cannot boost beyond the set percentage.

Step 4: Monitor Temperatures and Avoid Thermal Throttling

High CPU temperatures cause the system to reduce clock speeds to prevent damage, which stops turbo boost.

  • Download a free tool like HWMonitor or HWiNFO.
  • Run the program and monitor your CPU temperature under load (e.g., when running a game or benchmark).
  • If temperatures exceed 85-90°C, your CPU will throttle to cool down.

How to fix: Clean dust from fans and heatsinks, ensure fans are working, replace thermal paste if necessary, or improve airflow in your PC case.

Step 5: Update CPU Drivers and Chipset Software

Outdated or incorrect drivers can cause hardware performance issues.

  1. Visit your PC or motherboard manufacturer’s website.
  2. Download the latest chipset drivers for Windows 11.
  3. Install them and restart your PC.

Why this matters: Updated chipset drivers help Windows communicate properly with CPU features including turbo boost.

Step 6: Disable Background Applications That Limit CPU Performance

Some software or background processes may limit CPU speeds to save power or reduce heat.

  1. Open Task Manager by pressing Ctrl + Shift + Esc.
  2. Check for processes using excessive CPU or power.
  3. Close or uninstall unnecessary programs, especially those related to power management or system monitoring that might interfere.

Alternative method: Perform a clean boot to start Windows with minimal services and check if turbo speeds improve.

Step 7: Use Intel XTU or AMD Ryzen Master for Advanced Control

If basic steps don’t work, you can try official CPU tuning software.

  • Intel Extreme Tuning Utility (XTU): Allows you to monitor and adjust CPU performance settings.
  • AMD Ryzen Master: Similar tool for AMD processors.

These tools can help identify if turbo boost is being limited by software and sometimes allow manual adjustments.

Frequently Asked Questions (FAQs)

Why doesn’t my CPU reach turbo speed all the time?

Turbo boost activates only under certain conditions like CPU temperature, workload, and power availability. It’s normal for the CPU to run at base speed during light use.

Can outdated Windows cause turbo boost issues?

Yes. Missing updates might affect performance features, so keeping Windows updated is important.

Is it safe to force turbo boost manually?

Using tuning software to increase speeds beyond manufacturer limits can cause overheating or instability. Always proceed cautiously.

Does running on battery mode limit turbo speed?

Most laptops reduce CPU speeds on battery to save power. Plugging in your laptop usually enables full turbo speeds.

How do I know if turbo boost is working?

You can use tools like CPU-Z or HWMonitor to see current CPU clock speeds and check if they increase under load.

When Nothing Works

If you have tried all the above steps and your CPU still does not reach turbo speeds, consider the following:

  • Check for BIOS updates from your motherboard or laptop manufacturer and apply them carefully.
  • Contact your PC or CPU manufacturer’s support for hardware diagnostics.
  • Use official Microsoft support links: Windows Support.
  • Consider professional hardware inspection to rule out issues like faulty cooling or power delivery.

Conclusion

CPU turbo boost is an important feature that helps your computer run faster during demanding tasks. If your CPU isn’t reaching turbo speeds on Windows 11, start by checking BIOS settings and power plans. Make sure your system is cool and drivers are up to date. By following these detailed troubleshooting steps, you can often restore your CPU’s full performance without needing advanced technical skills.

Remember, gradual and careful adjustments are key to maintaining system stability and longevity. If problems persist, don’t hesitate to seek professional help or official support resources.
