How to overclock Xiaomi Redmi Note 8 Pro: 5 proven ways to speed up your smartphone

Introduction: Should we overclock the Redmi Note 8 Pro in 2026?

Xiaomi Redmi Note 8 Pro, released in 2019, is still popular with users thanks to the powerful MediaTek Helio G90T chipset and 64-megapixel camera. However, with the release of new versions of Android and MIUI, many owners notice that the device begins to “brake” — especially when launching modern games or multitasking. CPU overclocking or system optimization can return the previous “drive”, but it is important to understand that not all methods are equally safe.

In this article, we’ll look at 5 ways to speed up your Redmi Note 8 Pro, from harmless cache cleaning to deep overclocking through an engineering menu, which methods give real performance gains and which can lead to overheating of the chipset or locking the bootloader, and we’ll also analyze whether to overclock the smartphone based on its age or better consider alternatives like custom firmware.

Warning: some operations require unlocking the bootloader and may be unwarranted. If you are not willing to take risks, skip the advanced methods and focus on software optimization.

1. Preparation for acceleration: what to do before the changes

Before you start overclocking, make sure your Redmi Note 8 Pro is ready for loads.Neglecting preparation can lead to unstable operation or even hardware damage (for example, battery failure due to overheating).

Check the processor temperature in normal mode (use CPU Monitor)

Backup data through Settings → Additional → Backup

Charge the battery at least 70% (acceleration at low charge is dangerous!)

Make sure the MIUI version is updated to the latest stable (checked in Settings → About Phone)

Disable all background applications through Settings → Applications → Auto-Run-->

Pay special attention to cooling. Redmi Note 8 Pro is prone to overheating due to the compact body and powerful chipset. If you plan to overclock the processor, buy a cooling case in advance or use your smartphone in a ventilated room. Temperatures above 65 ° C when loaded - a signal to immediately reduce the frequency!

⚠️ Note: If your smartphone is already overheating in normal mode (for example, when shooting a video) 4K), Acceleration will only make the problem worse, in which case you can replace the heat paste first or clean the device of dust.

Also check the battery status, and if it's under 80 percent (as you can see in the AccuBattery app), it can accelerate degradation, so you'd better replace the battery first.

2. Software optimization: acceleration without risk for hardware

Don't get too excited about the processor settings! Often the Redmi Note 8 Pro's brakes are not about hardware limitations, but about a contaminated system. Start with these steps, they don't require root rights and are safe:

🧹 Cache and garbage cleanup: Use the built-in Security app (Settings) → Annexes → Security → Clean up! Delete unnecessary files, app residues and Google Play cache.
⚡ Turn off animations: Turn on Developer Mode (7 times click on Version) MIUI In Settings → About the phone, then in Settings → Additionally. → For developers install: Animation windows = 0.5x Animation of transitions = 0.5x Duration of the animator = Off.
🔄 Factory reset: Last resort, but effective. Save data before reset! Pathway: Settings → Additionally. → Recovery and discharge → Resetting settings.
📱 Shutdown MIUI-Chips: Features like Second Space, Game Turbo, or Smart Assistant eat resources. Turn them off in Settings. → Special facilities.

If you still do this, you can move on to more radical methods, but remember, overclocking through the engineering menu or custom core will void the warranty (if it still works).

💡

After cleaning the cache, restart the smartphone – this will allow the system to reassemble temporary files from scratch, which will speed up the work by 10-15%.

Comparison of optimization methods

Method	Productivity gains	Risks.	Need root?
Clearing the cache	5-10%	No.	No.
Shutdown of animations	15-20% (subjectively)	No.	No.
Reset to factory	20-30%	Loss of data	No.
Shutdown MIUI-chip	10-15%	No.	No.
Overclocking through MTK Engineering	30-50%	Overheating, blockage	Yes.

This method involves manually adjusting the frequencies of the MediaTek Helio G90T through a hidden engineering menu. It gives a noticeable boost in games and benchmarks, but requires caution. Redmi Note 8 Pro has 8 cores: 2 powerful Cortex-A76 (up to 2.05 GHz) and 6 energy-efficient Cortex-A55 (up to 2.0 GHz).

Step-by-step:

Install the MTK Engineering Mode app from Google Play (or download the APK from a trusted source).
Open the app and go to the Hardware Testing → MTK Settings section.
Select a Frequency CPU (if there is no partition, your MIUI version hides it, you will need root).
For Cortex-A76 cores, set a maximum frequency of 2200 MHz (normal — 2050 MHz).
For cores Cortex-A55 leave the standard 2000 MHz — their acceleration is useless.
Save the settings and restart the smartphone.

⚠️ Note: After the acceleration, monitor the temperature in CPU Monitor: If the temperature in a game (such as Genshin Impact or Call of Duty Mobile) is above 70°C, immediately reduce frequencies to 2100 MHz.

To test the results, run the benchmark AnTuTu or Geekbench, which is expected to increase 10-15% in single-core tests and 5-8% in multi-core tests, but in real-world tasks, the difference may not be noticeable due to the limitations of the Mali-G76 MC4 GPU.

What happens if you set the frequency above 2200 MHz?

If you exceed 2200 MHz on the cores of the Cortex-A76 Redmi Note 8 Pro begins to "trott" (automatically reduce frequencies) after 5-10 minutes of load. In the worst case, a sudden rebuke or damage to the chipset is possible. The manufacturer limited the maximum frequency for a reason - the limit is determined by the physical capabilities of the 12-nm process.

4.GPU overclocking and improving graphics in games

The processor is not the only bottleneck in the Redmi Note 8 Pro. The Mali-G76 MC4 graphics accelerator can also be overclocked, but there are even more pitfalls, and the wrong settings will lead to artifacts on the screen or a full driver crash.

GPU overclocking methods:

🎮 Through Game Turbo: Enable the Mode in Settings → Special facilities → Game Turbo and activate the option Improved graphics. It's not overclocking in a literal sense, but allows games to use more resources.
🔧 Through ADB-Commands: Connect the smartphone to the PC, turn on debugging USB and execute the command: adb shell setprop gpu.max_freq 850 The trunk frequency GPU — 820 MHz, maximum for acceleration — 850 MHz. Higher values cause overheating.
📊 Through the custom core: Install the Perseus Kernel (requires root and unlocked bootloader). GPU and control the voltage.

After overclocking the GPU, test stability in GFXBench or 3DMark. If you notice graphical glitches (flickering, tearing textures), return the standard settings. Also keep in mind that overclocking the GPU has a stronger effect on autonomy than overclocking the CPU - the time in games will be reduced by 20-30%.

💡

GPU overclocking is only effective in games that support the Vulkan API (such as PUBG Mobile or Fortnite).

5. Alternative methods: custom firmware and cores

If regular overclocking methods don’t work, consider installing custom firmware or a modified core.This is a radical step, but it could bring the Redmi Note 8 Pro back to life for 1-2 years.

Top.-3 speed-up:

🚀 LineageOS 20: Lightweight firmware based on Android 13, devoid of “heavy» MIUI. Dayet. +15% performance through optimized code.

To install custom firmware will require:

Unlock the bootloader via the Mi Unlock Tool (the process takes 7-14 days due to Xiaomi restrictions).
Install the custom TWRP recavator.
Swipe firmware and GApps (if not included in the build).

⚠️ Attention: Redmi Note 8 Pro with Android 12-based firmware+ The camera module may not work due to the closed source code of Helio G90T. Before firmware check if the build supports GCam.

If you are not ready for such drastic measures, try to optimize the current MIUI with the help of Magisk modules:

Displax’s Mod improves multitasking.
PowerHAL – manages the processor frequencies more flexibly than standard settings.
Thermal Configs – reduces the aggressiveness of trottling during heating.

6.Risks of overclocking: what could go wrong?

Overclocking the Redmi Note 8 Pro is always a tradeoff between performance and reliability, and even if you follow the instructions, you may run into problems.

🔥 Overheating: When accelerating to 2200+ MHz chipset temperature can reach 80-85°C, which results in automatic frequency reduction or shutdown.
🔋 Fast battery discharge: Overclocked processor consumes on 30-40% If the battery is already worn out, it's enough to power it. 2-3 high-hour.
🐢 trottling: MIUI aggressively restricts performance when heated, even after overclocking 10-15 play-off FPS may fall below baseline.
🚨 Loader locking: Some methods (e.g., changing frequencies through a MTK Rootless engineering can lead to soft-brick, and you can only fix this by flashing it over.
📉 "Iron" degradation: Constant operation at higher frequencies accelerates wear of transistors in the processor. 1-2 This can be a result of unstable work.

To minimize the risks, follow the following rules:

Do not overclock the smartphone if it is already overheating in normal mode.
Use only verified frequency values (no higher than 2200 MHz for the CPU and 850 MHz for the GPU).
Regularly test stability in Prime95 or 3DMark.
Return the standard settings if you notice artifacts or sudden reboots.

💡

On the Redmi Note 8 Pro with a worn-out battery (capacity < 70%), overclocking reduces battery life by 2 times, in which case it is better to replace the battery first.

7. Alternatives to dispersal: what to do if nothing helps?

If overclocking didn’t give the expected result or you’re not willing to risk the stability of your smartphone, consider alternative ways to improve performance:

🔄 Lowering screen resolution: In games, set the resolution 1600×720 staff-up 2340×1080. It'll reduce the load on you. GPU on 20-30%.
🧊 Use of cooling cover: Fan covers (e.g. Black Shark Cooling Case) reduce the temperature by a factor of 10-15°C, which allows the processor to work longer at high frequencies.
🔋 Replacement of thermopaste: Over time, the factory thermopaste dries. Applying a new one (e.g. Arctic) MX-4) may improve the heat transfer to 15-20%.
📱 Switching to “light” firmware: Firmware like Havoc-OS or CrDroid are optimized for weak iron and give performance gains without overclocking.
💰 Upgrade to a new smartphone: If the Redmi Note 8 Pro can not cope with modern tasks, perhaps it’s time to consider models like Poco X6 Pro or Redmi Note 13 Pro+.

Also, pay attention to background processes. Many apps (especially Chinese ones) continue to run in the background, eating resources. Use Greenify or the built-in Background Limitation feature in MIUI (Settings → Applications → Permissions → Auto Run).

💡

If you play Redmi Note 8 Pro, turn off Wi-Fi Assist and Mobile data roaming in the settings SIM-These features are constantly scanning the networks, putting additional strain on the processor.

FAQ: Frequent questions about overclocking the Redmi Note 8 Pro

Yes, but the options are limited. Without root, you can: Optimize MIUI (cache clearing, animations disable), use the MTK Engineering Mode to slightly overclock the CPU (up to 2100 MHz), install firmware through Fastboot (but this will reset all data). Deep overclocking (cores, GPU, voltage) will require an unlocked bootloader and root.

❓ What is the safest possible overclocking for daily use?

For everyday tasks (social networks, video, light games), we recommend: CPU: 2100 MHz for Cortex-A76 cores (instead of the standard 2050 MHz). GPU: 830 MHz (standard value - 820 MHz), These settings give an increase of 5-10% without critically affecting temperature and autonomy.

❓ What to do if after overclocking the smartphone began to overheat?

Follow this algorithm: Return the normal frequencies through the MTK Engineering Mode. Clean the case of dust (especially near the speaker and camera). Install the Thermal Pastor app to monitor the temperature. If the problem persists, replace the thermopast or battery. If the smartphone turns off when heated, this is a sign of trottling. Try rolling back the firmware or resetting.

❓ What games will not run on the overclocked Redmi Note 8 Pro?

Even with overclocking, some modern games won't work consistently: Genshin Impact (requires OpenGL) ES 3.2+, Mali-G76 It only supports 3.1. Diablo Immortal (locked due to non-compliance with the iron part requirements). Apex Legends Mobile (works, but with strong friezes at high settings). For these games, it is better to use cloud gaming (for example, Xbox Cloud Gaming or GeForce). NOW).

❓ Should you overclock the Redmi Note 8 Pro in 2026?

It depends on your goals: ✅ Worth it: If you play lightweight games (Brawl Stars, Clash Royale) or want to extend the life of your smartphone for another year. ❌ Don’t: If you plan to play heavy games (PUBG on ultra-settings or smartphone is already worn out (battery) < 70%, normal overheating. Most of the time, optimization. MIUI It gives a greater increase than acceleration, without risk to iron.
