# Why Do We Need It?
<p align="justify">If your laptop’s CPU is running very hot and you’ve tried to undervolt it, you’ve probably discovered there’s no easy way to do so—especially on laptops whose BIOS doesn’t expose those controls. I ran into the same issue with my Ryzen 7 5800H, despite numerous attempts, I couldn’t undervolt because the firmware simply wouldn’t allow it. While it may seem drastic, disabling <code>Turbo Boost</code> is one workaround—and you might be surprised how little real-world performance you lose by turning it off.</p>


# Why Tweak CPU Boost?
* **Heat & Noise:** Aggressive boosting spins fans faster and raises CPU temperatures, often causing thermal throttling and fan noise spikes.
* **Battery Life:** Reducing boost levels directly cuts power draw, extending unplugged runtime.
* **Workload Fit:** GPU-bound games or lightweight tasks rarely need max CPU frequency, so limiting boost can be unnoticeable in practice.
* **Fine-Grained Control:** Beyond the basic `Enabled`/`Disabled` options, Windows offers efficiency-focused and calculated-boost modes—some only visible after the registry tweak.


# Quick Registry Hack to Reveal Boost Modes

1.  **Open Registry Editor:** Press `Win+R`, type `regedit`, and click OK. (Be careful in the registry!)
2.  **Navigate to the Path:** In the top bar of the Registry Editor, paste:
```
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7
```
3.  **Modify _Attributes_:** Find `Attributes` on the right side, double-click it, and change its value from `1` to `2`.

Now, you can control the mode:

1.  Search for `Edit Power Plan` in Windows search and open it.
2.  Click `Change advanced power settings`.
3.  Expand `Processor power management`, then expand `Processor Performance Boost Mode`.
4.  You can now choose different _**`STATE/MODE`**_ for `On Battery` and `Plugged in`.


# Processor Performance Boost Modes

## Classic Modes

| Mode                 | Simplified Effect                                            | Use Case                                     |
| -------------------- | ------------------------------------------------------------ | -------------------------------------------- |
| Disabled             | No boost—CPU stays at base frequency.                        | Laptops seeking max battery life & low heat. |
| Enabled              | Standard boost—OS-managed boost when needed.                 | Everyday use with balanced performance.      |
| Aggressive           | Boosts readily to max frequencies, regardless of power draw. | Demanding workloads on well-cooled rigs.     |
| Efficient Enabled    | Boosts but favors energy efficiency over raw speed.          | Laptops needing mild boost without heat.     |
| Efficient Aggressive | Prioritizes efficiency but still seeks higher boost levels.  | Mixed-use systems wanting more boost safely. |

## `At Guaranteed` Variants

> Guaranteed performance level = the CPU’s nominal base frequency.

| Mode                               | Simplified Effect                                                                    | Use Case                                               |
| ---------------------------------- | ------------------------------------------------------------------------------------ | ------------------------------------------------------ |
| Aggressive At Guaranteed           | Requests a calculated extra boost above the base frequency for a precise jump.       | When you want controlled high boost.                   |
| Efficient Aggressive At Guaranteed | Same precise boost above base, but with efficiency constraints to limit power usage. | Modern systems needing strong boost with better power. |


# Which Mode Is Best for You?

* **Ultra-quiet/cool laptops:** Start with `Disabled`, then step up to `Efficient Enabled` if performance lags.
* **Balanced desktop/laptop:** `Enabled` or `Efficient Aggressive At Guaranteed` offers strong performance with decent power control.
* **Max-performance rigs:** Use `Aggressive` or `Aggressive At Guaranteed` —just keep an eye on thermals.

## A Friendly Advice

While tweaking these settings can be very beneficial, always make changes one at a time and observe your system's stability, temperatures, and performance.
