How to find RAM on a Xiaomi phone: a complete guide

Xiaomi smartphone owners, including Redmi and POCO, often face the need to accurately determine the amount of RAM installed, which is required not only to check the characteristics of the purchase, but also to diagnose problems with the performance of the MIUI or HyperOS system. Modern applications consume more resources, so understanding how much RAM is available to your device becomes critical for comfortable use.

There are several proven methods of obtaining this information, from built-in system utilities to third-party software. In this article, we will examine each method in detail, explain the difference between physical memory and virtual expansion, and consider the nuances that manufacturers often do not mention.

Verification through the system settings of Android

The easiest and most affordable way to find out the amount of RAM installed does not require installing additional software. In the shells of MIUI and HyperOS, this information is often hidden in deep menus, but it can be found by standard tools of the Android operating system, you need to go to the settings menu and find the section responsible for information about the device.

The path to data may vary slightly depending on the firmware version, but the logic remains the same: you need to open Settings, then scroll down to About. This is where your Xiaomi's basic specification is contained. However, the standard display often only shows the amount of built-in storage, and the RAM data can be hidden.

To see the details, click on the Memory or Storage bar inside this menu. The system will display the occupancy chart and the total volume figures. Note that this shows the physical volume of the chip installed in the factory, excluding the resources reserved by the system. This value is the reference value for your model.

Sometimes users confuse these numbers with the available space for installing applications. It is important to understand that RAM (RAM) and ROM (Embedded Memory) are different types of drives with distinct speed and destination characteristics. In this section, you see exactly the volume of the fast-acting buffer in which running programs are executed.

⚠️ Note: Some global versions of the firmware MIUI The section with detailed information about RAM can be hidden or show averaged data. If you do not find accurate numbers, use alternative methods described below.

Use of engineering menus and codes

For more advanced users, there is a way to get technical information through a special engineering menu, which allows you to see not only the total volume, but also the current CPU load and memory in real time. USSD-codes or commands in the application "Phone».

Type ##6484## on the call keyboard. This action will automatically open the CIT (Customer Interface Test) menu. There are many tests to check all components of a smartphone. You need to find a memory item, often called Memory or RAM Info.

The window that opens will show a technical summary. Look for the Total RAM string that will show the total physical volume of the chip. There may also be an Available RAM bar that shows how much is free right now, which is the most accurate, because it's read directly from the memory controller.

##4636##

Another useful combination is ##4636##. It opens the test menu. Select Device information or Running services (depending on the Android version). In the running services section, you can see how many megabytes or gigabytes of RAM is occupied by the system and applications, and how much is left in reserve.

⚠️ Warning: Be careful in the engineering menu. Do not change settings that you do not know the value of, as this can lead to unstable network operation or system failures.

Third-party diagnostic applications

If the built-in tools don’t give you the full picture, Google Play provides comprehensive hardware information, including the type of memory you installed (LPDDR4X, LPDDR5), frequency and number of channels, which is especially useful when comparing different Xiaomi models.

One of the most popular and reliable tools is the CPU-Z application. Once installed, run the program and go to the Device or Memory tab. Here you will see the exact amount of RAM specified by the chip manufacturer. The program will also show the current boot and frequency at which memory is currently running.

Another powerful tool is AIDA64, which is an app that generates a detailed report of all the components of a smartphone. Android OS -> Memory displays the full amount of physical memory. It also knows how to plot load graphs, which helps identify "voracious" applications that eat resources.

Using third-party software gives you the benefit of historical data and real-time monitoring, so you can track how memory consumption changes after you install a new firmware update or a specific application, and it helps diagnose memory leaks that are common in MIUI betas.

Memory Extension Memory Extension

Modern Xiaomi smartphones are equipped with Memory Extension technology, which allows you to use part of the built-in storage as virtual RAM, which is designed to improve multitasking on devices with a small amount of physical RAM. You can activate it in settings, but it is important to understand the principle of operation.

The system reserves, for example, 2, 3 or 4 GB from internal memory and adds them to the RAM pool. In the interface, this is displayed as the total value: physical memory plus virtual memory. However, the speed of this expanded volume is much lower, since flash memory technology is inferior to the speed of RAM chips.

To enable the function, go to Settings -> Additional -> Expansion of memory. Here you will see a volume slider. After changing the settings, you will need to reboot the device. The system will redistribute the file system, and the new volume will be taken into account in the overall calculations of available resources.

It is worth noting that on devices with a fast type of memory UFS 3.1, the effect of expansion will be more noticeable than on older models with eMMC. However, for heavy games, this feature gives a minimal increase in FPS, but helps keep more background applications open.

⚠️ Warning: Constantly writing and overwriting data in memory expansion mode can theoretically speed up the wear of the built-in drive, although modern controllers are good at load distribution.

Analysis of processor and model characteristics

Often, a smartphone is bought with your hands or a box is lost, and you don't know which version of memory is installed, and in this case, analysis of the processor model and the device model number helps. Each Snapdragon, MediaTek or Dimensity chipset has a limit on the type and maximum amount of memory it supports, which narrows the search.

Find the exact model name in Settings -> About Phone (e.g. Redmi Note 10 Pro). Then type that query into a search engine with the name "specifications" or "specs." Xiaomi's official website or authoritative technical portals will provide accurate information about the configurations in which the model was released.

It is important to know that the same phone model can be produced in different versions: with 6, 8 or 12 GB. RAM. Visually identical, so you can only trust software testing or labeling on a factory box. On a box, the volume is usually indicated in a Memory line or through a fraction, for example, 6GB+128GB.

Below is a table of correspondence of popular models and their memory configurations for quick orientation:

💡

Knowing the exact model of the processor helps to predict the type of memory used and its real speed, which is more important than dry volume digits.

Optimization and management of operational memory

Once you know how much memory you have, it's a question of how to use it effectively. The MIUI shell has built-in cleaning mechanisms, but they're not always effective. To manually clean, run the Security app and press the Cleanup button, which will close the background processes and free up resources.

For advanced users, the Developer Form feature is available. To activate the menu, you need to click 7 times on the version number in About Phone. In the developer menu, find the Background Process Limit. Here you can severely limit the number of simultaneous applications that work simultaneously, which will free RAM for the current task.

Also worth paying attention to is the autoload of applications. Many programs prescribe themselves to start, consuming memory constantly. Go to Settings -> Applications -> Permissions -> Autorun and turn off everything that is superfluous. This will significantly speed up the smartphone after you turn on.

Regularly restarting your device is a simple but effective way to combat memory fragmentation and system debris accumulation, so if your phone is starting to run slower, try restarting it by shutting down all applications, which will give the system a fresher state.

💡

Use the Memory Cleanup widget on your desktop for quick access to the RAM release feature without logging into the deep settings menus.
