Replacing RAM on an ASUS laptop: from choosing modules to testing

Replacement RAM on a laptop ASUS is one of the most effective upgrades for increasing productivity. Even budget models like Vivobook or gaming ROG Strix can get a second life after installing additional strips RAM. But before you take up a screwdriver, it’s worth understanding the nuances: not all laptops support memory expansion, and the wrong choice of modules can lead to conflicts or even failure.

In this article we will walk through the entire process from A to Z: how to check the current configuration RAM, select compatible modules for your model ASUS (be it ZenBook 14, TUF Gaming A15 or ROG Zephyrus), it is safe to disassemble the case and install new memory. We will pay special attention to typical mistakes that beginners make - from ignoring dual-channel mode until the strips are installed incorrectly in the slots. If you've never opened a laptop, don't worry: our step-by-step instructions with photos and videos will help you avoid problems.

1. Compatibility check: what memory does your ASUS laptop support?

The first and most important step is to determine what RAM modules compatible with your model. U ASUS there are laptops with soldered memory (for example some ZenBook or Vivobook S), where to replace RAM impossible. To avoid wasting your money, check:

• 🔍 Laptop model - find it on the sticker below or in System Information (Win + R → msinfo32).
• 📄 Official documentation - on the website ASUS In the support section of your model, look for specifications (Memory Specification).
• 🛠️ Current configuration - use utilities like CPU-Z (tab SPD) or HWiNFO.
• 🔧 Physical examination - if there is a lid at the bottom with the inscription RAM or MemoryMost likely the memory is removable.

Please note memory type (usually DDR4 or DDR5 for new models), maximum volume (for example 32 GB or 64 GB) and number of slots. In gaming ROG often two slots, and ultrabooks ZenBook - one or the memory is soldered. Also check clock frequency: if your processor supports DDR4-3200, don't take it DDR4-2400 - this will limit productivity.

⚠️ Attention: Laptops ASUS on processors Intel 12th generation and newer (for example, ROG Strix G15 2022) often require memory DDR5, which is incompatible with DDR4. Check this in the documentation!

Laptop series	Memory type	Max. volume	Number of slots	Soldered?
ZenBook 13/14 (UX325/UX425)	LPDDR4X	16–32 GB	Soldered	Yes
Vivobook S14/S15 (S433/S533)	DDR4	32 GB	1–2	No
TUF Gaming A15/17 (FA506/FA706)	DDR4	64 GB	2	No
ROG Strix G15/G17 (G513/G713)	DDR4/DDR5	64 GB	2	No
ASUS ProArt StudioBook	DDR4	128 GB	4	No

2. Choosing RAM: what to buy for ASUS

Once you know what memory is needed, all that remains is to select specific modules. Here are the key parameters to pay attention to:

• 🔄 Dual-channel - if the laptop has two slots, buy two identical slots (for example, 2x16 GB) to increase the throughput by 50-100%.
• ⚡ Such frequency — take the maximum supported by your processor (for example, DDR4-3200 for Ryzen 5000).
• 🔋 Low voltage memory - for ultrabooks (ZenBook) search LPDDR4X (but it is usually soldered).
• 🛡️ Brand - reliable manufacturers: Corsair, Kingston, Crucial, Samsung, G.Skill.

For gaming laptops ROG or TUF Gaming We recommend modules with radiators (For example, Corsair Vengeance or G.Skill Ripjaws), since they heat up less under high loads. If you are purchasing a single stick for an upgrade (for example, adding 16 GB to an existing 8 GB), make sure that timings (CL16, CL18 etc.) match the already installed memory.

Examples of compatible modules for popular models:

• ASUS TUF Gaming A15 (2021) → Crucial CT16G4SFRA32A (16 GB, DDR4-3200, CL22).
• ROG Zephyrus G14 (2022) → Kingston KF564S38IBK2-32 (32 GB, DDR5-4800, CL40).
• Vivobook Pro 15 (K3500) → Samsung M471A2K43DB1-CWE (16 GB, DDR4-3200, CL22).

⚠️ Attention: If you install memory with a frequency higher than standard (for example, DDR4-3600 instead of DDR4-2933), it can operate at a lower frequency without manual configuration in the BIOS.

3. Preparing for replacement: tools and safety precautions

Before disassembling your laptop, prepare everything you need. You will need:

• 🔧 Screwdriver - usually Phillips #0 or #1 (for small screws).
• 🧲 Magnetic mat or a tray for screws - so as not to lose them.
• 📱 Smartphone - for photographing the location of screws and connectors.
• 🧴 Thermal paste (optional) - if you remove the cooling system.
• ⚡ Antistatic wrist strap - for protection against static electricity.

Also follow these steps:

1. Turn off your laptop and disconnect the charger.
2. Remove battery (if it is removable). For many ASUS (For example, TUF Gaming) the battery is fixed with screws.
3. Work for flat, clean surface no carpets or fabrics that accumulate static.

Check for warranty seals (damage to them will void the warranty)-->

If your laptop is under warranty, please note: replace it yourself RAM may cancel it. U ASUS some models (eg ROG Strix) have warranty seals on the cover screws. In this case, it is better to contact a service center.

4. Disassembling an ASUS laptop: access to RAM slots

The disassembly process depends on the model. Most ASUS there are two options:

1. Separate cover for RAM - y TUF Gaming, ROG Strix and some Vivobook.
2. Complete disassembly - y ZenBook and thin ultrabooks (requires removing the entire bottom cover).

Let's consider both cases.

Option 1: RAM Cover (Easy Access)

For example, at ASUS TUF Gaming A15 (FA506) or ROG Strix G15 (G513):

1. Turn the laptop over and find the cover with the symbol RAM or Memory.
2. Unscrew the screws (usually 2-4 pieces) and carefully pry the cover with a plastic card.
3. Under the cover you will see 1–2 slots SO-DIMM with fasteners on the sides.

Option 2: Complete disassembly (difficult access)

For models like ZenBook 14 (UX425) or Vivobook S14 (S433):

1. Unscrew all screws on the bottom cover (they can be hidden under the legs).
2. Carefully pry the cover around the perimeter, starting from the corner. Be careful - the latches are fragile!
3. After removing the cover, find the slots RAM (usually next to the cooler or under the battery).

What to do if the screws won't come off?

If the screw is “slipped” or does not budge:

1. Try a screwdriver with better grip (such as one with a rubber tip).

2. Apply a little WD-40 and wait 5 minutes.

3. As a last resort, use screw extractor or contact service.

For some models (for example, ROG Zephyrus G14) slots RAM may be hidden under the cooling system. In this case:

1. Disconnect the cooler and battery cables.
2. Unscrew the screws securing the radiator.
3. Remove the heatsink (you may need to replace the thermal paste later).

5. Installing new RAM

Once you have access to the slots, proceed carefully:

1. Retrieving Old Memory:
   • Bend the fasteners on the sides of the slot (they should snap out to the sides).
   • Plank RAM rises a little - carefully pull it out, holding it by the edges.
2. Installing new memory:
   • Combine key (notch) on the bar with a protrusion in the slot.
   • Insert the module at an angle of ~45° and press until the latches click.
   • Make sure the bar sits level and the latches click into place.

If you have two slots and are installing two strips, place them in the slots 1 and 3 or 2 and 4 (usually they are marked with different colors) to activate dual-channel mode. For example, at ASUS ROG Strix G15 slots A1 And B1 (see markings on the motherboard).

1. Are the strips inserted correctly (the latches should click into place).

2. Memory compatibility with motherboard.

3. Contacts on the modules (if necessary, wipe them with an eraser).-->

⚠️ Attention: Don't touch the contacts RAM bare hands - oil and sweat can cause oxidation. Grab the planks by the edges!

6. Laptop assembly and testing

After installing the memory, reassemble the laptop in reverse order:

1. Make sure that all cables and connectors are connected.
2. Tighten the screws (do not overtighten!).
3. Connect the battery and charger.

Now check if the new memory is recognized:

1. Turn on your laptop and go to BIOS (usually the key F2 or Del when loading).
2. Find a section Memory Information or System Info — the new volume should be displayed there.
3. Boot Windows and check in Task Manager (tab Performance → Memory).

If the memory amount is displayed incorrectly (for example, instead of 32 GB it shows 16 GB), possible reasons:

• 🔄 The strips are installed in the wrong slots for dual-channel.
• 🔧 One of the strips is faulty or incompatible.
• 🔄 Disabled in BIOS XMP profile (for high frequency memory).

To test stability, use the following utilities:

• MemTest86 — boot memory test (it’s better to run from a flash drive).
• AIDA64 — checking the bandwidth in the section Memory Benchmark.
• Prime95 — stress test to check for errors.

7. Common mistakes and their solutions

Even with careful replacement, problems can arise. Here are the most common ones and how to fix them:

Problem	Possible reason	Solution
Laptop won't turn on	The RAM stick is not fully inserted	Check the latches, remove and reinsert the module
Memory capacity has not increased	Incompatible timings or frequency	Check specifications, update BIOS
Blue screens (BSOD)	Defective module or strip conflict	Test each strip individually
The laptop gets hotter	Poor contact of cooling system	Reinstall the heatsink, replace the thermal paste
Memory works in single-channel	The strips are installed in the wrong slots	Rearrange the modules according to the markings on the board

If after replacement RAM The laptop starts to slow down or crashes into BSOD, try:

1. Reset BIOS to factory settings (remove battery CMOS for 30 seconds).
2. Update BIOS to the latest version (download from the website ASUS).
3. Install the strips one at a time to identify the faulty module.

FAQ: Answers to frequently asked questions

Is it possible to replace the memory on ASUS ZenBook if it is soldered?

No, if the memory is soldered to the motherboard (as in most ZenBook series UX), it is impossible to replace it without specialized equipment. In this case, the only way to increase performance is to optimize the software or buy a new laptop.

Which is better: one 32 GB stick or two 16 GB sticks?

Two 16 GB sticks are preferable, as they work in dual-channel mode, which increases throughput by 30–50%. One 32 GB stick deprives you of this advantage, although it gives you room for a future upgrade.

Do I need to update the BIOS before replacing RAM?

Update BIOS recommended if you are installing memory at a higher frequency than was originally supported. For example, for ASUS TUF Gaming A15 (2020) BIOS update may add support DDR4-3200 instead of DDR4-2933.

Is it possible to mix planks from different manufacturers?

Technically it is possible, but this is fraught with problems: unstable operation, reduction in frequency to the minimum, or refusal to boot. If you mix, make sure that the bars have the same frequency, timing and volume. It is better to use a set of two identical modules.

How to check if new memory works in dual-channel?

Run the utility CPU-Z and go to the tab Memory. In the field Channel # must be indicated Dual. You can also check the bandwidth in AIDA64 — in dual-channel it will be approximately 1.5–2 times higher than in single-channel.
