Where is the RAM in the Xiaomi phone: disassemble the smartphone on the shelves

Why users are looking for RAM in Xiaomi and when they really need it

Have you ever wondered where the RAM is physically hidden in your Xiaomi? For most owners, this question remains abstract until the phone starts to brake, spontaneously reboot or requires an upgrade. In practice, knowing the location of RAM (RAM) is critical in three cases: when you try to replace the chip yourself (which is extremely risky), diagnosing hardware failures or buying a used device with suspected “dilted” components.

Xiaomi’s current smartphones, from the budget Redmi Note to the flagship Xiaomi 14, are built on the principle of maximum compactness. There are no removable memory modules, like in old PCs: RAM is integrated into the motherboard at the chip level. This means that physical access to it requires a complete disassembly of the case, and any error can lead to irreversible damage to the device. Before grabbing the screwdriver, it is worthwhile to understand: do you really need to dig into the “inneries?”

In 90% of cases, memory problems are solved software-based, such as cleaning the background, turning off heavy applications or resetting to factory settings, but if you're determined to disassemble the phone -- for example, to replace the charging connector and want to look at RAM -- this article will help you do that safely. We'll look at where the RAM chip is, how to identify it among other components, and why some Xiaomi models may have different locations.

Anatomy of the Xiaomi smartphone: where to look for RAM on the motherboard

The RAM in Xiaomi smartphones is a LPDDR (Low Power Double Data Rate) chip soldered directly to the motherboard, unlike the eMMC/UFS, which can also be soldered but sometimes executed in a removable format (older models), RAM is always integrated, standardized but depends on the generation of the processor and the architecture of the board.

In most devices, the RAM chip is:

• 📍 Near the processor (SoC) — usually to the right or bottom of it. This is the most common location in models on Snapdragon (for example, Xiaomi 13 Pro or Snapdragon). POCO F5).
• 📍 Under a metal screen (in passive cooled models) – for example, in Black Shark or gaming smartphones, where RAM can be covered with a heat distribution plate.
• 📍 On the back of the board - in budget models (for example, Redmi). 9A), where components are distributed to save space.

Visually, the RAM chip looks like a small black rectangle (usually 8×6 mm or 10×8 mm) with a label that contains the letters LPDDR and version numbers (for example, LPDDR4X or LPDDR5). On the board, it can be denoted by the acronym RAM or DRAM. It is important not to confuse it with a flash memory (storage), which is often nearby, but has a different marking (for example, UFS 2.2).

How to distinguish RAM from other chips: a visual guide

On the motherboard of the Xiaomi smartphone dozens of chips, and the inexperienced eye easily confuses RAM with a Wi-Fi module, power controller or even a processor. To avoid errors, pay attention to the following signs:

If you've disassembled the phone and aren't sure which chip is in front of you, use a camera lens or macro lens to read the marking. For example, Samsung's RAM chip might have the inscription K3UH7H70AM-AGCL (that's 8GB LPDDR4X) and the drive might have the inscription THGBF7G9L4LBATR (UFS 2.1 by 128GB).

⚠️ Warning: Don't touch chips with your bare fingers - static electricity can damage chips. Use an antistatic bracelet or at least discharge yourself by touching a grounded metal object.

Step-by-step: how to get to RAM in Xiaomi

If you're determined to disassemble your phone, follow this algorithm. Warning: self-disassembly is insecure and can lead to breakdown! Take the Xiaomi Redmi Note 11 Pro+, one of the most popular models with typical component layouts, for a demonstration.

Turn off the phone and remove it. SIM-memory-card|Discharge the battery before 20-30% (to avoid fire in case of damage)|Prepare tools: plastic shoulder blades, cross screwdriver, tweezers, antistatic bracelet|Take photos of each step of disassembly for reverse assembly-->

Step 1 Remove the back cover

On most Xiaomi models, the lid is attached to clips and glue. Carefully tuck it with a plastic blade from the bottom edge (near the charging connector) and slowly lead along the body. In the Redmi Note 11 Pro+, under the lid you will find:

• 🔋 Battery (glued, removed after the disconnection of the plume).
• 📱 Motherboard (fixed on screws under the battery).
• 📶 Antenna modules (thin metal plates at the edges).

Step 2. Battery disconnection

Before you touch the board, be sure to turn off the battery by disconnecting the power plume (usually a white latch connector). In the Redmi Note 11 Pro+, it is at the top of the board. Use a plastic blade to gently lift the connector.

Step 3: Dismantling the motherboard

Unscrew all the screws that attach the board (Xiaomi often uses Y000 or PH00 screws). Carefully raise the board, starting at the top edge. On the back side, you will see RAM and storage chips. In this model, RAM is located to the right of the processor (Snapdragon 695) and marked as LPDDR4X.

💡

If you are disassembling a phone to replace RAM, keep in mind: in 99% of cases this is impossible without specialized equipment (sweeter station, BGA-Chips soldered with ball contacts (BGA), Replacing them requires professional skills.

Xiaomi models with non-standard RAM arrangement: exceptions to the rules

Most Xiaomi smartphones have RAM next to the CPU, but there are exceptions to this, which are worth knowing if you work with rare or gaming models:

1.Series of Black Shark (Gaming Smartphones)

In Black Shark 4/5, RAM can be hidden under an active cooling system, a metal plate with heat pipes, and to get to the chips, you have to remove this plate, which requires thermal paste and accuracy. These models often use LPDDR5 at an increased frequency (up to 6400 MHz).

2. Xiaomi Mix Fold and foldable models

In foldable smartphones, the board is divided into two pieces connected by a flexible plume. RAM can be on the second board (under the screen), rather than on the main board. For example, in Mix Fold 2, memory chips are distributed between both boards to balance weight.

3. Budget models (Redmi) 9/10A)

In the cheapest Xiaomi smartphones, components are often placed on the back of the board to save space, so in the Redmi 9A, RAM (LPDDR4X) is under the battery, and to see it, you need to flip the board.

4. Models with Mediatek Dimensity

In Mediatek-powered phones (like the POCO X4 Pro), RAM can be integrated into the processor chip itself (called internal memory, iRAM), in which case you won’t find a separate chip — memory is part of the SoC.

⚠️ Note: In the Mediatek Dimensity 1000+ and a new attempt to "update" RAM by replacing the chip will lead to the inoperability of the device - the memory is soldered inside the processor and is not subject to upgrade.

What happens if you damage the memory chip: consequences and signs of malfunction

RAM is one of the most vulnerable components of a smartphone, and even minor damage (such as overheating when soldering or static electricity) can make it go downhill.

• 🔄 Cyclic reboots – the phone turns on, loads to the logo MI It's a sign of damage to the RAM boot sector.
• 🐢 Extreme brakes -- the interface is lagging, the applications are not opening, even though the processor is not loaded.
• 📵 Artifacts on the screen – stripes, flickers or “snow” on the display may indicate damage to the graphic buffer in RAM.
• 🔋 Fast battery discharge – faulty memory can cause the processor cores to constantly reboot, which increases power consumption.

If you see these symptoms, check your phone programmatically first:

1. Install MemTest86 (Xiaomi will need to unlock the bootloader).
2. Run the memory test via fastboot: fastboot flash boot memtest.img fastboot boot memtest.img
3. Errors in the test (e.g., Memory address error at 0x12345678) will indicate physical damage to RAM.

It's impossible to restore damaged RAM at home, and the only way out is to replace the chip at the service center (costs between 3,000 and 10,000). ₽ depending on the model) or buying a new phone if the repair is unprofitable.

1. Connecting the battery plume.

2. Integrity of contacts on the motherboard.

Only then suspect a malfunction of RAM - in 80% of cases the problem is mechanical damage during assembly.-->

Is it possible to increase RAM in Xiaomi: myths and reality

There are a lot of tips on how to "boost RAM" on Xiaomi, from "magic apps" to soldering new chips, to see what's true and what's deceitful:

Myth 1: RAM Expander Apps Really Increase Memory

Programs like ROEHSOFT RAM-Expander or Swapfile create a paging file on the drive, but it's not RAM. The read/write speed from flash is hundreds of times lower than LPDDR, so this upgrade will only worsen performance. MIUI has a built-in RAM Boost feature (in Settings → Section "Additional"), but it only optimizes the use of existing memory.

Myth 2: You can replace the RAM chip with a more capacious one

Theoretically, yes, but in practice, it is:

• ⚠️ Requires a soldering station with precise temperature control (for the purpose of BGA-chips need settings 220-260°C).
• ⚠️ You need a complete flashing of the phone, as the memory controller in the SoC must support the new chip.
• ⚠️ The cost of work will exceed the price of the phone (in services for such a replacement charge from 15 000). ₽).

Reality: The Only Way to Increase RAM

If you really lack RAM, there are only two options:

1. Buy a model with a large volume of RAM – for example, instead of Redmi Note 12 with 6 GB take the version with 8 GB.
2. Use cloud memory — MIUI has a Smart RAM Extension (in Settings → Memory) that uses up to 3GB of storage as a buffer. It's not full RAM, but it helps with multitasking.
