How to increase RAM in an ASUS laptop: a detailed guide with photos

Why is it worth upgrading the RAM in an ASUS laptop?

Laptops ASUS are some of the most popular devices on the market, but even top models begin to slow down over time when working with modern programs. Video editing in Adobe Premiere, multitasking with a dozen browser tabs or running Cyberpunk 2077 at minimum wages - all this requires more RAMthan was provided upon purchase. Adding an additional RAM module is often cheaper than buying a new laptop, and the effect is noticeable immediately: the system stops freezing, games run smoother, and heavy applications run more stable.

However, not all laptops ASUS support memory upgrade. For example, ultrabooks series ZenBook often have sealed RAM, and gaming models ROG Strix or TUF Gaming usually allow you to add a second module. In this article we will look at how check compatibility, choose the right RAM stick, physically install it and avoid common mistakes that can damage your laptop.

Step 1: Check if you can increase the RAM in your ASUS laptop

Before you buy a new memory stick, make sure that your laptop supports the upgrade at all. There are three ways to do this:

• 🔍 Documentation. Find your laptop model (on the sticker below or in System Properties) and check the specifications on the official website ASUS. Look for the section Memory or RAM — the maximum volume and number of slots are indicated there.
• 🛠️ Visual inspection. Turn the laptop over and locate the service cover (usually marked with a screw with a screwdriver icon). If there is no cover, the memory is most likely sealed.
• 💻 Software diagnostics. Use utilities like CPU-Z (tab SPD) or HWiNFOto see the number of slots and occupied modules.

Critical information: ASUS laptops with 12th generation Intel processors and newer (e.g. ZenBook Pro 14 OLED or ROG Zephyrus G14 2023) often have sealed LPDDR5 memory. In such cases, an upgrade is not possible without replacing the motherboard.

If your laptop only one slot under RAM (for example, in ASUS Vivobook S14), you will have to replace the current module with a more capacious one. If there are two slots, but one is empty, you can simply add a bracket. The best option is pair work two identical modules (dual mode), which increases productivity by 10–15%.

Step 2: Select compatible RAM

An error in choosing RAM can lead to the laptop simply not turning on. Here are the key parameters to pay attention to:

Parameter	What does it mean	How to check
Memory type	DDR3, DDR4 or DDR5. ASUS 2018–2020 usually use DDR4, new models use DDR5.	B CPU-Z in the tab Memory or on the official website.
Frequency	Measured in MHz (for example, 2400, 3200). Must match the supported motherboard.	In the laptop specifications or via AIDA64.
Form factor	For laptops - SO-DIMM (short planks). Desktop DIMM won't fit!	On the packaging or in the product description.
Volume	8 GB, 16 GB, 32 GB. The maximum depends on the model (for example, ASUS TUF A15 supports up to 32 GB).	In the documentation or via msinfo32 (type in Windows search).

Example of correct selection: for ASUS ROG Strix G15 (2021) with processor Ryzen 7 5800H will do DDR4-3200 SO-DIMM 16 GB (if the slot is free). If the laptop already has 8 GB, it is better to buy another 8 GB stick for dual mode than to install one with 16 GB.

⚠️ Attention: Some laptops ASUS (For example, ZenBook Flip) require memory support ECC (error checking). Installing regular DDR4 without ECC may result in blue screens of death (BSOD).

Step 3: Prepare tools and work area

To install RAM in a laptop ASUS you will need:

• ✅ Phillips screwdriver (usually PH0 or PH1). In some models (for example, ROG Zephyrus) screws with a non-standard head are used - a set may be needed iFixit.
• 🧲 Magnetic mat or tray for screws (so as not to lose small parts).
• 🧴 Plastic spatula (for careful opening of the latches). Metal tools may scratch the casing.
• 🔌 Antistatic wrist strap (optional, but recommended for static protection).
• 📸 Smartphone — take a photo of the location of the screws and connectors before disassembling!

Work for flat, clean surface (table covered with cloth). Avoid carpets - they accumulate static electricity. If you do not have an antistatic wrist strap, before starting work, touch your hand to a metal object (for example, a radiator) to remove the charge.

⚠️ Attention: In laptops ASUS with aluminum housing (eg ZenBook Duo) screws can be of different lengths. By mixing them up, you risk damaging the motherboard when tightening!

Step 4: Disassemble the laptop and install RAM

The disassembly process differs depending on the model, but the general scheme is as follows:

1. Turn off your laptop and disconnect the power cable. Remove the battery if it is removable (in most modern models ASUS built-in battery).

2. Turn the laptop over and unscrew all screws on the bottom cover. In some models (for example, ASUS ROG Strix Scar) the lid is secured with latches - carefully pry it off with a plastic spatula, starting from the corner.

3. Locate the RAM slot(s). They are usually located under the black protective cover or next to the cooler. In laptops ASUS TUF slots can be hidden under a metal screen.

4. If the slot is occupied, carefully move clamps to the sides (they will click with a characteristic sound). Remove the old plank by pulling it upward at an angle of 30°. Insert the new strip at the same angle, then press until the latches click.

Important nuance: in some laptops ASUS (For example, Vivobook Pro 15) one slot can be covered with a cooler thermal pad. Do not remove it unless necessary - this will disrupt the heat dissipation!

After installation, reassemble the laptop in reverse order. Do not over-tighten the screws as this may cause the case to crack. Connect power and turn on the device.

What to do if the laptop does not turn on after installing RAM?

1. Check whether the bar is tightly inserted (until the latches click).

2. Make sure the contacts are not dirty (clean with an eraser if necessary).

3. Try returning the old stick - if the laptop works, the new RAM is incompatible.

4. Reset BIOS (remove CMOS battery for 10 seconds or use jumper CLR_CMOS, if there is one).

Step 5: Check the functionality and configure the BIOS

After turning on the laptop:

1. Go to BIOS (usually the key F2 or Del when loading). Check if the new memory appears in the section System Information or Memory Settings.

2. If the volume is displayed incorrectly (for example, 8 GB instead of 16 GB), the mode may be enabled Legacy Support. Disable it and save the settings (F10).

3. On Windows, open Task Manager → Performance → Memory. The full amount of RAM should be displayed there. If not, check the system bit depth (32-bit Windows does not support more than 4 GB).

To test stability, use the following utilities:

• 🔧 MemTest86 — checks RAM for errors (runs from a flash drive).
• 📊 AIDA64 — cache and memory test (Tools → Cache & Memory Benchmark).
• 🎮 3DMark — if you upgraded your laptop for gaming, run a stress test.

⚠️ Attention: If after installing new RAM the laptop ASUS starts to randomly turn off or overheat, check if the memory strip is blocking the cooler air ducts. In models ROG Strix Sometimes you have to shorten thermal pads.

Step 6: Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when upgrading RAM. Here are the most common:

• 🔌 Frequency mismatch. If you install DDR4-3200 in a laptop that only supports DDR4-2400, the memory will operate at a lower frequency. Check the specifications!
• 🔄 Wrong dual mode. To activate the two-channel mode, the strips must be of the same volume and frequency. For example, 8 GB + 16 GB will not give any performance gain.
• 🔥 Overheating In compact laptops (for example, ASUS ZenBook 13) Additional RAM can increase heat dissipation. Monitor temperatures in HWMonitor.
• 🔒 BIOS lock. Some models ASUS (especially with processors Intel 11th generation) require manual enablement of support for new modules in the BIOS (Advanced → Memory Configuration).

If after the upgrade there are BSOD with type errors MEMORY_MANAGEMENT or IRQL_NOT_LESS_OR_EQUAL, most likely the problem is incompatibility of the strips. Try:

1. Install the modules one at a time (to identify the defective one).
2. Update BIOS to the latest version.
3. Reset BIOS settings to factory defaults.

Extreme case: If the laptop does not turn on even with the old RAM stick, you may have damaged the slot. In this case, only a service center will help.

FAQ: Answers to frequently asked questions

Is it possible to install DDR5 in a laptop with DDR4?

No, that's impossible. Connectors SO-DIMM DDR4 And SO-DIMM DDR5 physically incompatible (different number of pins and keys). Attempt to install DDR5 into a DDR4 slot may damage both the motherboard and the RAM module.

How much RAM do you need for gaming in 2026?

Minimum comfortable volume - 16 GB (for example, for GTA V or Fortnite). For modern games like Alan Wake 2 or Star Citizen recommended 32 GB. In this case, not only volume, but also frequency is more important: for Intel Core i7/i9 or Ryzen 7/9 DDR4-3200 or DDR5-4800 is optimal.

Which is better: one 16 GB stick or two 8 GB sticks?

Two 8 GB sticks dual mode will give a performance increase of 10–15% compared to one 16 GB stick. However, if you plan to upgrade to 32 GB in the future, it makes more sense to immediately take 16 GB and later add another 16 GB module.

How can I find out how many RAM slots my ASUS laptop has?

Methods:

1. Run CPU-Z and go to the tab SPD — all slots will be displayed there.
2. Type at the command line wmic memphysical get MemoryDevices.
3. Physically inspect the motherboard (requires disassembly).

Do I need to update the BIOS after installing new RAM?

Updating the BIOS is recommended if:

• New memory is not detected.
• The laptop gives errors like Memory not installed.
• You have installed modules with a frequency higher than the standard for your model.
