How to increase RAM on Xiaomi Redmi: from virtual RAM iron-upgrade

Owners of Xiaomi Redmi smartphones sooner or later face a shortage of RAM, especially if the device is used for multitasking, gaming or working with “heavy” applications. 6-8 GB RAM They start to “slow down” through 1-2 But what if you don't plan to buy a new phone and the current configuration doesn't keep up with the load?

In this article, we will discuss all the current ways to increase RAM on Redmi - from software tricks with virtual memory to physical upgrades (yes, this is possible on some models!). MIUI And alternative solutions that can help unload the system without interference with the hardware, and it's important that not all methods are equally safe, and some can lead to loss of warranty or failure of the device, more details are given in the relevant sections.

1. Virtual memory (RAM Expansion): how it works and whether to include

The easiest and official way to “increase” RAM on Xiaomi Redmi is to activate the function RAM Expansion (aka Memory Extension or Memory Extension) – This technology uses a portion of the internal memory (UFS Or eMMC) as an additional buffer for background processes, essentially, the smartphone tricks the system into showing more features. RAM, what is.

The feature is available on most Redmi models with MIUI 12.5 and newer, but there are nuances:

• 📱 It only works on Qualcomm Snapdragon chipsets (series) 6xx/7xx/8xx) MediaTek Dimensity (1000+). On the budget Helio G may not be available.
• 🔄 Virtual memory does not speed up the phone — it only allows you to keep more applications in the background, but the speed of their reboot remains the same.
• ⚡ Increases battery consumption on 5-15% Due to frequent read/write operations in internal memory.

How to turn on:

1. Go to Settings → About the phone → All the characteristics.
2. Put it on the RAM line. 5-7 The Memory Extension Menu is available.
3. Select the amount of virtual memory (usually 1, 2 or 3 GB).
4. Reset the device.

Myths about virtual memory that are worth debunking:

• ❌ «It’s the same as physical RAM — no, speed. UFS 2.1 into 5-10 times lower than LPDDR4X.
• ❌ «Function is useless" - useful for multitasking, but not for games or rendering.
• ❌ «Harmful to memory: modern chips can withstand hundreds of thousands of rewrite cycles, the risk is minimal.

⚠️ Note: On Redmi Note 10 Pro and older models UFS 3.1 Virtual memory is more stable than on budget devices with eMMC 5.1. If after activation of the function the phone starts to "lag", turn it off and clear the cache in Settings → Memory. → Cleanup.

2. Optimizing current memory: how to free RAM without root

Before resorting to radical methods, try maximizing the efficiency of current RAM. Xiaomi Redmi has built-in tools and hidden settings that will help the memory load.

Main “eaters» RAM:

• 🎮 Games (especially with background loading textures, such as Genshin Impact or Call of Duty Mobile).
• 📱 Messengers (Telegram, WhatsApp) with active chats and media files.
• 🔄 Background processes MIUI (For example, com.miui.analytics or com.xiaomi.midrop).
• 🌐 Browsers with multiple tabs (Chrome, Mi Browser).

Step-by-step optimization:

Disable the autoloading of applications|Remove unused widgets|Limit background activity|Clear the cache of system applications|Turn off animation. MIUI-->

Deep setup (requires activation of Developer Mode):

1. Turn on Developer Mode by tapping 7 times on the MIUI version in Settings → About Phone.
2. Go to Settings → Additional → For developers.
3. Install: Limitation of background processes → «Maximum 2 process. Do not save actions → On. (turns off transition animations). Debugging by USB → On (required for some tweaks).

Adaptive brightness

Auto-update of applications

💡

If RAM is still not enough after optimizing, try using Lite versions of apps (such as Facebook Lite or Messenger Lite). 30-50% memory.

3.Use of SWAP-File: An alternative to virtual memory

If the function RAM Expansion is not available on your Redmi model, you can create it. SWAP-A file is an analog of virtual memory that runs at the Android kernel level, which requires root rights but gives you more control over sizes and priorities.

Advantages SWAP Memory Extension:

• ⚡ Flexible size setting (up to 4 GB can be allocated).
• 🔧 Opportunity to choose type SWAP: file.
• 📉 Less battery load with proper configuration.

Instructions for the establishment SWAP-file:

1. Get root access (for example, through Magisk).
2. Install the Swap File Creator app from Google Play.
3. In the application settings, specify: File size: 1024 MB (1 GB for starters. SWAP: File (easier to delete if necessary) Storage area: /data/swapfile.

Create Swap File

Termux

free -h

The output should appear Swap string with a non-zero value.

⚠️ Attention: Don't create SWAP-File on a microSD card will cause it to wear out quickly, and avoid sizes over 2 GB on budget models (Redmi) 9A, Redmi 10C), This can cause lags due to slow internal memory.

4. Physical increase in RAM: are there possible upgrades to Redmi

Few people know, but some Xiaomi Redmi models allow you to physically replace or add RAM, this applies to flagship devices with a modular design, for example:

• 🔧 Redmi K50 Gaming Edition – Supports Upgrade RAM Up to 12 GB (sweetening equipment required).
• 🔧 Redmi Note 11 Pro+ 5G — replace the chip LPDDR4X on a more capacious (up to 8 GB).
• 🔧 POCO F4 GT — similarly K50, But with better documentation for the upgrade.

What it takes to upgrade:

• 🛠️ A heat-air soldering station (e.g. Quicko) T12).
• 🔍 Microscope or magnifier ×10-×20.
• 💾 Memory chips LPDDR4X or LPDDR5 (motherboard-compatible).
• 📄 The diagram for your model (see on the 4PDA or XDA Developers).

Step-by-step process (simplified):

1. Remove the back cover and battery (requires a mediator and a hair dryer to heat the glue).
2. Disconnect the display and motherboard plumes.
3. Find RAM chips (usually marked as Samsung) K3 hynix H9).
4. Carefully remove old chips with a soldering hair dryer (temperature) ~350°C).
5. Install new chips while observing polarity.
6. Flow the device through EDL-Mode (May require Xiaomi authorization).

⚠️ Attention: Physical RAM upgrade on Redmi – a procedure with a high risk of damage to the motherboard or loss IMEI. No rationing experience. SMD-It is better to contact a specialized service. Also note that after replacing the chips, you may need to flash through the Mi Flash Tool with the authorization of the Xiaomi account.

5. Alternative methods: when to increase RAM is impossible

If none of the above methods are suitable (for example, you have a Redmi). 8A 2GB RAM and MIUI 11), consider alternative solutions that will help reduce memory load:

Light firmware:

• 📱 Pixel Experience or LineageOS – Used on the 20-30% less RAM than MIUI.
• 🔄 MIUI Lite – Lightweight version for weak devices (not available on all models).

Cleaning applications:

• 🧹 Greenify – suspends background processes.
• ⚡ Boost for Redmi – Optimizes the settings MIUI low-radiation.

3. Cloud solutions:

• ☁️ Shadow PC GeForce NOW — Starting games on a remote server (does not load your Redmi).
• 💾 Termux + Linux Deploy – Transferring heavy tasks (such as code compilation) to a lightweight virtual machine.

Hardware tricks:

• 🔋 Replacing the battery with a new one – a worn-out battery forces the system to aggressively close applications to save energy.
• 🌡️ Cooling the phone – overheating leads to trottling and artificially restricting RAM.Use cooling pad for games.

💡

If your Redmi is released before 2020 (like the Redmi Note 7), physically increasing RAM is almost impossible, in which case the best way out is to buy a new device or switch to lightweight firmware.

6 Risks and how to avoid them

Any interference with the Xiaomi Redmi RAM is fraught with risks. Let’s consider the main threats and ways to minimize them:

Checklist before any manipulation:

Create a backup in Mi Cloud|Check the battery charge (minimum 50%)|Disable Two-Factor Authentication in Mi Account|Download the original firmware for your model|Prepare tools (screwdrivers, mediators)-->

What to do if something goes wrong:

• 🔄 Soft brick (phone turned on but not booted): Fastboot with the Mi Flash Tool.
• ⚡ Hard brick (no button response): required EDL-Mode and Authorized Xiaomi Account.
• 📵 Loss of loss IMEI: restore through QCN-file (instructions are available on the 4PDA).
