Can I add RAM to the Xiaomi TV: myths and reality?

Xiaomi TVs based on Android TV or Google TV often face a shortage of RAM, especially when running multiple applications or games at the same time. Users are beginning to look for ways to upgrade hardware, assuming that you can simply buy the RAM bar, as in a PC or laptop. However, the architecture of smart TVs is fundamentally different from a computer – here the memory is integrated into the motherboard and cannot be replaced without specialized equipment.

In this article, we will explain why adding RAM to Xiaomi Mi TV, Redmi Smart TV or Xiaomi TV A Pro is impossible in 99% of cases, but we will talk about legal ways to optimize existing resources. You will learn how to free RAM without losing functionality, what system settings will help reduce the load, and when you really need to think about buying a new device.

Why Xiaomi TVs can’t be physically added to RAM

Unlike desktop computers, where RAM is a removable DIMM or SO-DIMM module, Xiaomi TVs use soldered memory like LPDDR. It is integrated directly into the motherboard (most often in the chipset) and does not have connectors to connect additional modules.

• 🔧 Board layout: Manufacturers save space by placing RAM and flash memory (eMMC) in the same chip as the processor (so-called SoC, or System on a Chip). For example, Mi TV 4S or Redmi X50 models use an Amlogic or MediaTek chipset, where memory is tightly tied to architecture.
• 📏 Form factor: TVs are designed to be minimally thick. Additional slots for RAM would require larger dimensions, which is contrary to the trend for ultrathin devices.
• ⚡ Energy consumption: Removable memory requires additional controllers and power circuits, which increases cost and reduces energy efficiency — a critical parameter for machinery running 24/7.

Even if you theoretically find a compatible memory chip (which is almost impossible for an average user), soldering it will require:

• 🔬 A soldering station with precise temperature control (a chip overheating causes it to fail).
• 🧪 Experience with BGA- packets (multi-output chips where the legs are hidden under the body).
• 💻 Specialized software for flashing a memory microcontroller (without it, the TV won’t recognize new memory).

⚠️ Warning: Attempts to solder the memory on a Xiaomi TV board result in loss of warranty and in 80% of cases, complete failure of the device.

How to check current memory usage

Before looking for ways to increase RAM, make sure that the problem is really lacking. Xiaomi Android TVs allow you to monitor resource usage through hidden menus or third-party apps.

1. Open the settings → Device → About the program.
2. Find the Build Number and click on it 7 times in a row to activate the developer mode.
3. Go back to the main settings menu and select a new section for developers.
4. Scroll down to the Debugging block and turn on the Process Statistics option.

Now, when you press the Back button on the remote in the upper right corner of the screen, a panel with data about:

• 📊 The memory used (e.g. 1.2 GB/2 GB).
• ⚡ Load CPU (percentage of processor usage).
• 🔄 Active processes (how many applications are running in the background)

Alternatively, install the AIDA64 app from Google Play (if available for your model) and provide detailed information about the type of memory (LPDDR3/LPDDR4), its frequency and loading in real time.

💡

If the TV is slowing down a lot, but statistics show that there is enough free memory (for example, 500 MB out of 2 GB), the problem may be in the fragmentation of flash memory or overheating of the chipset. Try resetting to factory settings (Settings → Storage and reset → Data reset).

Methods of optimizing RAM without upgrading

While you can’t physically increase the RAM in a Xiaomi TV, you can significantly improve its performance through software methods.

1. Clearing background processes

Android TV tends to keep apps in memory even after they're closed, to force RAM to be released:

• 🛑 Close all applications via the Home button → the cross in the upper right corner of the thumbnail.
• 🔄 Restart the TV (Settings) → The device → Reboot).
• 🚫 Turn off auto-run unnecessary services in Settings → Applications → Auto-run.

2. Use of “light” versions of applications

Many streaming services (YouTube, Netflix, Kodi) have lightweight versions for weak devices, such as:

• 🎥 YouTube Go (if available for your model) consumes 30% less RAM.
• 📺 SmartTubeNext is an alternative client for YouTube with optimized code.
• 🎮 RetroArch instead of Play Market emulators (e.g., for NES or SNES).

3. Transfer of applications to an external drive

While this won’t increase the RAM, releasing internal memory (eMMC) will reduce the system load. Connect a USB- flash drive or a SD- card (if there’s a slot) and transfer heavy applications there:

1. Go to Settings → Applications.
2. Select an app (such as Kodi or Twitch).
3. Click Warehouse → Change → External Drive.

⚠️ Warning: Not all applications support external portability, system services (e.g. Google Play Services) will remain in internal memory, and the speed of USB 2.0 will be lower than with the built-in eMMC.

4. Disable animations and visual effects

The Android TV interface uses animations that consume up to 100-150 MB of RAM.

1. Activate the Developer Mode (as described above).
2. In the section For Developers, find:
3. The scale of the animation windows → No animation.
4. The scale of the transition animation → Without animation.
5. Duration of animation → Off.

Can you programmatically increase RAM? Myth-debriefing.

On the Internet, there are often tips for "increasing RAM" through:

• 📱 Swap file on the flash drive.
• 🔧 Change the kernel parameters through build.prop.
• 🖥️ Firmware with "optimized" memory.

Let’s see why these methods don’t work or harm the device.

Myth 1: Paging file on USB- drive

Some gurus suggest creating a swap partition on a flash drive and mounting it as virtual memory, which is theoretically possible on a Linux PC, but there are critical limitations on Android TV:

• ❌ The Android kernel in Xiaomi TVs does not support swap on external media.
• ❌ The USB 2.0 read/write speed (~30 MB/s) is 100 times slower than LPDDR4 (~3 GB/s).
• ❌ Permanently writing to a flash drive will reduce its life (especially cheap models with MLC- chips).

Myth 2: Editing build.prop

Instructions are made to change the parameters in /system/build.prop, such as:

dalvik.vm.heapsize=512m


ro.config.low_ram=true

In practice:

• ⚠️ These parameters only affect the Dalvik virtual machine (an outdated runtime for Android), but not the physical machine RAM.
• ⚠️ Incorrect values will cause the system to crash (infinite boot or "bootloop").
• ⚠️ After the firmware update, all changes will reset.

Myth 3: Castom firmware with "enhanced" memory

Some users believe that firmware like LineageOS or ATV Custom ROM can unlock hidden memory, which is impossible for two reasons:

1. Hardware limitation: The firmware cannot physically add memory if it is not on the board.
2. Brick Risk: Unofficial firmware for Xiaomi TVs often contains bugs leading to loss of IMEI or broken Wi-Fi.

The only legitimate way to increase RAM is to buy a TV with a larger TV, such as the Xiaomi TV Q2 75′′ has 3 GB of LPDDR4, while the budget models (Redmi Smart TV A55) – only 1.5 GB.

Comparison of Xiaomi models by the amount of RAM

If your TV is really not doing well due to a lack of RAM, it may be time to consider buying a new model, and the table below shows Xiaomi TVs that are up to date for 2026, showing the amount of RAM and internal memory:

Please note:

• 📺 Models with 3 GB RAM (Xiaomi TV Q2, Xiaomi TV A Pro) are suitable for gaming (NVIDIA GeForce NOW, Xbox Cloud Gaming) and multitasking.
• 💾 The volume ROM is important for installing applications: 8 GB is enough for 10-15 programs, 32 GB is enough for 50+.
• ⚡ The MediaTek MT9611/MT9638 chipset is more energy efficient than Amlogic, which reduces heat under high load.

💡

If your TV is less than 2 GB RAM and slows down when viewing 4K-If you're optimizing for video or games, you're only going to have a temporary effect, and you're going to think about buying a model with 3GB of memory and support. HDMI 2.1.

What to do if the TV is slowing down due to memory loss

If all optimization methods are exhausted and the TV is still laying, follow this algorithm:

1. Check the temperature of the chipset. Overheating (above 80°C) causes trottling (forced performance decline). Use the app AIDA64 or an infrared thermometer. If the temperature is high: 🪟 Make sure the vents on the back are not closed. 🌡️ Move the TV away from the heat sources (batteries, cookstove). 💨 Force the charge to cool with the USB- fan (connects to the TV port).

Reset the settings to factory. This will remove unnecessary cache data and reset the background processes. Path: Settings → Storage and Reset → Data Reset.

Update your firmware. The manufacturer can optimize memory management in new software versions. Check for updates in Settings → About Program → System Update.

Limit background activity. In Settings → Applications turn off autostart for:

• 📱 Social Networking (Facebook, VK).
• 🎮 Game launchers (Google Play Games)
• 📊 Analytics Services (Google Analytics)

If nothing helps, consider the following options:

• 🔄 Sell + buy: Xiaomi models hold the price well in the secondary market. You can sell an old TV and buy a new model with more memory.
• 🛠️ Repair/replacement: Service centers sometimes offer to replace the motherboard with a similar, but with a large volume RAM (for example, from 1.5 GB to 2 GB).
