How to enable additional RAM on Xiaomi: overclocking, setting up and optimization

Introduction: why Xiaomi smartphone "extra" RAM?

You have noticed that your Xiaomi Redmi Note 12 or POCO X5 Is Pro slowing down when multitasking? Or do you want to make the most of Xiaomi? 13 Ultra for games like Genshin Impact? the solution may be lurking in a hidden feature MIUI/HyperOS — virtual memory (RAM This technology allows you to use part of the built-in storage as an additional RAM, increase the total volume to 3–7 GB!

But there are nuances: not all models support the function, and incorrect activation can lead to accelerated wear of flash memory. eMMC/UFS (In this guide, we'll discuss how to safely enable virtual RAM Xiaomi: What models support the technology and whether it is worth using it all the time.

Spoiler: With Xiaomi 14 and new HyperOS devices, virtual memory has changed its algorithm to activate automatically at high loads, but older models like the Redmi Note 10 Pro will have to dig deeper into the settings.

Which Xiaomi smartphones support RAM expansion?

Virtual RAM technology was introduced in MIUI 12.5 and developed in later versions.

• 📱 Supported officially: All devices on MIUI 13/14 HyperOS with Snapdragon chipsets 7xx/8xx or Dimensity 900+ (for example, Xiaomi 12T, POCO F4 GT, Redmi K50).
• ⚠️ Partial support: Budget models on Snapdragon 6xx or Helio G (e.g. Redmi 10) may have a feature, but enabling it will give a minimum performance boost.
• ❌ Not Supported: Devices older than 2020 (e.g. Redmi Note 8 Pro) or with 2-3GB of physical RAM.

To find out exactly if your smartphone supports the feature, check:

1. Open the Settings. → The phone. → Version. MIUI/HyperOS.
2. If the version is newer than 12.5.4.0, the probability of support is 90%.
3. MediaTek chipsets (e.g., Dimensity 1200) require firmware at least MIUI 13.0.5.

Important! On HyperOS devices (such as the Xiaomi 14 or Redmi K70), the feature can be called Dynamic RAM Expansion and run automatically. You can't manually turn it off, the system decides when to use virtual memory.

Step-by-step: how to enable virtual RAM on Xiaomi

If your device supports the function, follow this instruction, and the process differs depending on the shell version:

For MIUI 13/14:

1. Go to Settings → Additional Settings → Memory Extension (or Settings → Memory → Virtual RAM).
2. Select the amount of virtual memory: 1 GB, 2 GB or 3 GB (maximum depends on the model).
3. Click Apply and restart the device.

For HyperOS:

1. Open Settings → Performance → Dynamic RAM.
2. Activate the automatic extension slider.
3. The system will select the optimal volume (usually 2-5 GB).

Note: On some models (e.g., POCO X3 Pro), the path may differ: Settings → Special Features → Memory → Virtual RAM. If no point, your device does not support the function.

Optimal settings for virtual RAM for different tasks

Not always the maximum amount of virtual memory means better performance.

Critical: On devices with eMMC 5.1 (e.g. Redmi 9A), virtual RAM can speed up wear by 15-20% when used intensively. If your smartphone is older than 2 years, it is better to limit 1 GB or turn off the function altogether.

💡

Before you start the game, turn on the option “Optimize for performance” in the graphics settings – this will make the system more actively use virtual RAM.

Problems and Solutions: Why Does Virtual RAM Not Work?

Even if you turn on a function, it may not have the desired effect. Let's look at the typical problems and ways to solve them:

• 🔄 After rebooting, the settings are reset: It's a bug MIUI 13 on some models (like the Redmi Note 11).Solution - upgrade to firmware MIUI 14.0.3+.
• 🐢 Smartphones are getting slower: Virtual RAM eMMC drives can backfire. Turn off the function and clear the cache in Settings → Memory. → Clean up.
• 🔋 Fast battery drain: Virtual memory increases the load on the processor. Try reducing the capacity to 1 GB or disable the function for battery life.
• 🚫 Option not available after the update: On some devices (e.g, POCO F3) After the update to HyperOS, the function is hidden. ADB:

adb shell settings put global virtual_ram_enabled 1


adb shell settings put global virtual_ram_size 3072

Warning: Use of ADB-commands require an unlocked bootloader and can cause a reset. If you're not sure, you better contact the service center.

💡

On HyperOS devices, virtual RAM works as a plug-and-play system, which distributes resources itself, and manual intervention can upset the balance.

Alternative ways to increase productivity without virtual RAM

If your smartphone doesn’t support memory expansion or you’re afraid of risks, try these methods:

• ⚡ Optimization MIUI/HyperOS: Turn off animation: Settings → Special facilities → Remove animations. Activate Performance Mode in Settings → Battery. Limit the background activity of applications in Settings → Annexes → Permits → Auto-start.
• 🎮 For gamers: Use Game Turbo (built-in) MIUI). Install. GFX Tool for fine-tuning graphics in games. MIUI Optimization through ADB (root):

adb shell settings put global miui_optimization_disabled 1

💡 Lifehack: On devices with Snapdragon 8xx (For example, Xiaomi 12 Pro can be enabled Force GPU Rendering in the developer settings. It reduces the load on the CPU, increases energy consumption.

Myths and Truths About Virtual RAM on Xiaomi

There's a lot of rumors going around technology, and we're going to look at the most popular ones.

⚠️ Attention: Virtual RAM It's not a physical replacement, it's just a temporary offloader for peak loads, if you have 4GB of physical memory, even if you have a physical memory. +3GB virtual won’t make a smartphone as fast as an 8GB model LPDDR5.

• ❌ Myth: “Virtual RAM spoiler." ✅ True: UFS 3.1 wear is minimal (about) 1–2% There are only risks on old eMMCs. 5.0/5.1.
• ❌ Myth: “The function only works in games." ✅ Truth: Virtual memory is used by the system for any background processes, including browser and instant messengers.
• ❌ Myth: “You need to include the maximum volume." ✅ Truth: Excessive virtualization RAM It can slow down due to frequent access to the storage device.

🔍 Test in practice: On Xiaomi 13 Pro (12 GB) LPDDR5X + 3GB of virtual) gains in Geekbench 6 were only 5-7 percent in the multithreaded test. 3DMark Wild Life Improvement Reached 12% Thanks to Better Texture Processing.
