How to increase the performance of Xiaomi RedmiBook 9: from software tweaks to upgrades to iron

Xiaomi RedmiBook 9 is a popular notebook with a good price/quality ratio, but over time even it begins to slow down. The reasons can be different from a clogged system to overheating of the processor. In this article, we will discuss all possible ways to increase performance, from basic Windows settings to upgrade components and overclocking.

It's important to understand that not all methods are equally effective. For example, cleaning up the boot will increase the amount of time you have. 5-10%, a replacement SSD on NVMe, before 40%. We have distributed tips on the degree of impact on speed, so you can choose the best option for your tasks and budget.

If your RedmiBook 9 is slow to open programs, warms up or frisitizes when you're loaded, this guide will help you get it back to speed. Let's start with the simplest and free.

1. Windows Optimization: System Cleaning and Autoboot

The first thing to do is to remove the garbage from the system. Even on a new laptop, temporary files, cache and unnecessary programs accumulate over time, which eat up resources. On RedmiBook 9, with its modest 8 GB of RAM, this is especially critical.

Start by cleaning the disk:

1. Open This Computer, Right-Click on Drive C: and Select Properties → Clearing the disc.
2. Check all items (especially Temporary Files, Recycle Bin, Update Log Files).
3. Click Clear system files and repeat the procedure.

It'll free up until 5-15 GB space, which is especially important for models with SSD 256 GB.

The next step is to disable the autoload of unnecessary programs:

• 🔧 Press Ctrl. + Shift + Esc, go to the Autoboot tab.
• 📉 Sort programs by column Impact on launch.
• ❌ Disable everything except antivirus, drivers, and critical utilities (e.g. Xiaomi Quick Apps or other software). NVIDIA GeForce Experience, if you have them installed).

Don’t forget to defragment (if you have a HDD) or optimizing SSD:

Win + R → dfrgui → Select the C: → Optimize the disc

For SSD Choose Optimize (this will run the command). TRIM, It cleans the dead memory cells).

Delete temporary files through "Disk Cleanup"|Disable unnecessary programs in the boot|Defragmentation/optimization of the disk|Remove old restore points (via System Settings) → System protection")|Clear the browser cache (Chrome, Edge, etc.)

Updating drivers and BIOS: Why is this a critical issue for RedmiBook 9?

Outdated drivers are one of the main reasons for lags and poor performance, especially in RedmiBook 9, where they often work “curvely”:

• 🖥️ Intel Video Driver UHD Graphics (leads to artifacts in games and brakes when watching videos).
• 🔊 Realtek Audio Driver (can cause sound stuttering).
• 📶 Intel Wi-Fi Driver AX200/AX201 (leads to communication breakdowns).

You can update drivers in two ways:

1. Through Device Manager: Win + X → Device Manager → Right-click on the device → Update the driver → Auto Search: Windows doesn’t always find the latest version.
2. Manually from the manufacturer's website: 🌐 For video card: Intel Driver & Support Assistant. 🌐 For Wi-Fi/Bluetooth: Intel's download page AX200. 🌐 For the rest: Xiaomi official website (choose the RedmiBook model) 9).

Special attention should be paid to the update BIOS. RedmiBook 9 has new versions BIOS correct:

• 🔥 Overheating problems (improves fan management).
• ⚡ Power-consuming bugs (increase battery life).
• 🖥️ Compatibility with new SSD and RAM.

⚠️ Attention: Update BIOS — If you interrupt the process or use the wrong firmware, the laptop may stop turning on. Before upgrading: Connect the laptop to the power source. Close all programs. Download the firmware ONLY from the official Xiaomi website.

3. Power Management: How the Right Settings Save Resources

RedmiBook 9 is the default Balanced mode, which isn’t always optimal. If you want maximum performance (for example, for video editing or games), switch to High Performance:

Control Panel → Equipment and sound → Power supply → High performance

But there's a caveat: this mode increases heat and reduces battery life.

• 🔋 In the Additional Power settings, set: Minimum CPU state is 5% (instead of 0%); maximum CPU state is 90% (instead of 100%); Battery threshold is 20% (so that the laptop does not run to zero).
• 🔄 Turn it off. USB-Selective suspension (it can cause lags when connecting devices).

For advanced users, there is another trick – unlocking. TDP (The heat pack of the processor. 9 Intel Core i5-10210U The default is the limit in 15W, But it can be upgraded to 25W through:

• 🔧 ThrottleStop (for overclocking and power management).
• 🔧 Intel XTU (official utility for fine-tuning).

⚠️ Attention: Increase TDP increases productivity by 10-15%, But it also heats the processor very much. Without good cooling (like a fan stand), this can lead to trottling).

4.Iron upgrade: what can be replaced in RedmiBook 9

If the software methods do not give the desired increase, it is time to think about upgrading components. RedmiBook 9 allows you to replace:

The most effective upgrade is a replacement SSD Stock drive in RedmiBook 9 is often slow (especially in models with a high-end SATA SSD). For example, the transition from Kingston A400 Samsung 980 Pro gives you:

• 🚀 Increased read/write speed from 500 MB/s to 3,500 MB/s.
• ⏱️ Reduce Windows boot time from 30 to 10 seconds.
• 🎮 Lack of friezes in games (e.g. in games) GTA V or Cyberpunk 2077 when loading textures).

Modules will be suitable for replacing RAM DDR4 2666 MHz from Crucial, Kingston or Samsung, the main thing is that they are dual-channel (set in pairs, for example, 2×8 Single-channel mode reduces productivity by 15-20%.

⚠️ Attention: Replacement SSD RedmiBook 9 Be careful with the plumes, they're fragile. If you've never taken a laptop out, you better go to the service: ~1500-2000 ruble.

5.Cooling: How to prevent trottling and overheating

RedmiBook 9 is known for overheating problems, especially during long-term loads.°C, trottling is triggered - automatic frequency reduction, which is why the laptop begins to "lay down».

The first thing you need to do is to clean the cooling system:

• 🧹 Remove dust from the vents (you can vacuum at minimum power).
• 🔧 Remove the bottom cover and clean the radiator and fan with a brush or canister of compressed air.
• 🧴 Replace the thermopaste (original on RedmiBook) 9 squirts 1-2 Recommended: Arctic MX-6 (Good price/quality balance.Thermal Grizzly Kryonaut (for extreme cooling).

If cleaning didn’t help, try the software methods of temperature control:

• 🌡️ ThrottleStop – allows you to limit the temperature of the processor and adjust the voltage (undervolting).
• 🌡️ MSI Afterburner + RivaTuner – to control the frequency of the graphics card.

For example, in ThrottleStop you can put:

FIVR → CPU Core → reduce voltage by 50-100 mV (start with -50 mV and test stability).

It'll lower the temperature by 5-10°C without loss of productivity.

For passive cooling, use:

• 🪑 Fans stand (e.g. Cooler Master NotePal) X3).
• 🖥️ External cooler for laptop (connected through the USB).

Do not put your laptop on soft surfaces

6. Overclocking and fine-tuning: for advanced users

If you're willing to take risks, you can try overclocking the processor and RAM. On RedmiBook 9 Intel Core i5-10210U This gives rise to 5-15%, but it requires caution.

Methods of acceleration:

• 🔧 Intel XTU (Extreme Tuning Utility: Allows you to boost Turbo Boost to 4.2 GHz (instead of the standard 3.9 GHz). TDP before 25W (But it's a lot of heat on the laptop).
• 🔧 ThrottleStop: Unlocking BD PROCHOT (Remove artificial frequency restriction; adjust the Speed Shift for more aggressive acceleration.

Use the RAM to disperse. MemTest86 To check stability after changing timings. RedmiBook 9 can be tried:

• Increase the frequency from 2,666 MHz to 2,933 MHz (if the modules support).
• Reduce the timelines (for example, with CL19 before CL17).

⚠️ Warning: Dispersal may lead to: 🔥 Overheating and automatic shutdown of the laptop. ⚡ Reduced battery life. 💥 Losing warranty (if laptop warranties, don't take risks!) Be sure to back up data before overclocking and check stability in stress tests (AIDA64, Prime95).

If overclocking is not suitable for you, but you want more performance, consider alternative OSes:

• 🐧 Linux (Ubuntu, Mint) – less load on hardware, but not all programs are supported.
• 🪟 Windows 11 LTSC — «lightweight version without unnecessary services.

On the RedmiBook. 9 Linux Mint is running on the 10-20% faster 10 daily.

7.Optimize for Games: How to Make the Most of RedmiBook 9

RedmiBook 9 is not a gaming laptop, but it can run many projects (for example, it is not a gaming laptop, CS:GO, Dota 2, GTA V at low settings:

Graphic settings:

• 🎮 In games, get permission. 1280×720 instead 1920×1080.
• 🖥️ Turn off the anti-aliasing (FXAA instead MSAA).
• 🌿 Reduce the detail of shadows and effects.

Programming tweaks:

• 🔧 Use Radeon Software (if you have discrete graphics) or Intel Graphics Command Center to optimize games.
• 🔧 Enable Game Mode in Windows (Win) + G → Settings → Game mode).
• 🔧 Turn it off. NVIDIA GeForce Experience (if any) as it eats resources.
