How to find out the amount of RAM on Xiaomi Redmi 8: all ways

Why check RAM on Redmi 8?

RAM is a key component that determines the speed of your Xiaomi Redmi 8. If your smartphone starts to “slow down”, spontaneously close applications or slowly switch between tasks, the first diagnostic is to check the available amount of RAM. But how do you do it correctly?

Owners of Redmi 8 often face confusion: specs indicate 3 or 4 GB of RAM, but how to make sure that the manufacturer did not “save”? or how to understand how much memory is actually available to the system after downloading MIUI? In this article, all working methods of verification, including hidden MIUI functions and third-party utilities.

Important: The RAM capacity on Redmi 8 can’t be increased physically (as opposed to the internal memory), but knowing the current performance, you can optimize the device’s performance, such as turning off background processes or choosing “light” firmware.

Method 1: Using standard MIUI settings

The easiest method is to use the built-in MIUI tools, which do not require any additional applications to be installed and is suitable even for beginners.

1. Open the Settings menu (the gear icon on the main screen).
2. Scroll down and select the About Phone section.
3. Tap on General characteristics or characteristics of the device (name depends on the version of MIUI).
4. Find the RAM line – here will be the physical amount of RAM (for example, 3 GB or 4 GB).

⚠️ Note: This section displays full memory, not free! To see how much RAM is currently occupied, use Task Manager (see method 3).

Make sure the version MIUI at least 10 (otherwise, the item may not be available)|Compare the specified volume with the characteristics on the box|Write down the serial number (useful for warranty)-->

If the About Phone section doesn't show RAM information, you might have custom firmware, in which case you'll move to method 2 or 4.

Method 2: Using the Security App

The Security app in MIUI not only protects against viruses, but also provides detailed information about the system. Here's how to find RAM data:

1. Launch the Security app (shield icon).
2. In the lower menu, select the Optimization or Acceleration tab.
3. At the top of the screen, you'll see a memory usage chart.
4. The Memory Use section will open, where the total RAM volume and current loading will be indicated as a percentage.

💡 Useful tip: In this section, you can manually close unnecessary processes, freeing up memory: MIUI Automatically manages background tasks, and forced closure can lead to rebooting applications and increased battery consumption.

If the Security app doesn't have the Optimization tab, update it via Google Play or MIUI App Store.Outdated versions may not display full information.

Method 3: Task Manager (Fast View)

To quickly check the current RAM load, use Task Manager, which will show how much memory is currently occupied, but will not display the full amount of RAM.

Instructions:

1. Click on the recent apps button (square at the bottom of the screen).
2. Swipe up the screen to open the full list of tasks.
3. At the top of the screen, you'll see a panel that shows you how much memory you're using: 📊 RAM occupied (e.g. 1.8 GB/3 GB). 🔄 Free (remainder of available memory).

⚠️ If the task manager displays 0 GB freely, but the smartphone is stable - this is not a mistake! MIUI It caches data aggressively, and free memory doesn't always mean "unused." It automatically frees up resources when needed.

Method 4: Through the Engineering Menu (for Advanced)

The engineering menu (#4636##) provides advanced system data, including detailed information about RAM, which is suitable for advanced users, as it requires caution.

Step-by-step:

1. Open the Phone app.
2. Enter the combination: ##4636## (no spaces).
3. In the menu that appears, select Phone Information or Usage Statistics.
4. Scroll down to the Memory block: 📱 Total RAM — full-time memory. 🔄 Available RAM — free memory at the moment. 📉 Used RAM — volume.

⚠️ Warning: Do not change other options in the engineering menu unless you are sure of their purpose! Incorrect settings can lead to network loss or overheating of the processor.

Method 5: Third-party applications (CPU-Z, AIDA64)

If standard methods don't work or you need the most detailed information, install specialized utilities. We recommend two proven applications:

CPU-Z

A free utility showing the full characteristics of the device, including RAM.

1. Download CPU-Z from Google Play.
2. Open the app and go to the Memory tab.
3. In the section RAM will be indicated: 🔢 Total Memory - Full volume. 📊 Used Memory - busy. ⚡ Memory Type – Type of memory (for example, LPDDR4X).

AIDA64

A more advanced analogue with advanced diagnosis.

1. Install AIDA64 from the official store.
2. Start and select System → Memory.
3. Pay attention to the lines: 📱 Total RAM — total. 🔄 Free RAM — memory-free. 📈 Memory Usage History – Timeline.

💡 Useful advice: B AIDA64 You can create a system report (Menu). → Report → Share) and save it in.txt or.html format, which can be useful for diagnosing malfunctions or contacting a service center.

What if the RAM volume does not match the declared?

Sometimes Redmi 8 users find that the settings display a smaller amount of RAM than the box indicates. For example, instead of 4 GB, 3.7 GB is shown.

• 🤖 Systemic processes (MIUI Android).
• 🎮 Graphics processor (video memory).
• 🔒 Secure storage (for encryption).

But if the difference is significant (for example, 2GB is displayed instead of 4GB), it may indicate:

• 🛠️ Memory module malfunction (diagnosis in the service is required).
• 📱 Fake device (check out) IMEI via *#06#).
• 🔄 Castom firmware with errors in the core.

🔍 How to authenticate Redmi 8?

1. Enter the phone application: ##6484## (Equipment Test).
2. Compare the serial number on the box and in settings (Settings → About phone → General information).
3. Check out the IMEI at imei.info.

💡

If the RAM volume in the settings differs from the stated by more than 10% (for example, 3.5 GB instead of 4 GB), this is an occasion to contact the Xiaomi service center - perhaps the memory module is defective or a fake board is installed.
