Buying laptop RAM before checking the machine is how a quick upgrade turns into a return. The memory may be soldered, one slot may be hidden behind the base cover, or the system may need DDR5 when the spare module in your drawer is DDR4. Ten minutes with the exact model number will answer most of that before you reach for a screwdriver.
Quick Answer
Find the full model code on the underside label or in Windows System Information, then read its specification sheet and service manual. Look for SODIMM slots, soldered memory, maximum capacity and DDR generation. Confirm the current layout in Task Manager or a hardware-information tool, but treat software slot counts as a clue rather than proof. The ASUS Vivobook Go 15 with 8GB/256GB was listed at R7,999 in Evetech's July 2026 snapshot; its price says nothing about your laptop's slot layout, which must be checked by exact model.
🏷️ Start with the complete model code
A family name such as TUF, Legion, Victus or Katana is too broad. One chassis can ship with different processors, boards and memory layouts across regions. Copy the complete alphanumeric code, including the suffix after the main model number.
In Windows, press Win + R, enter msinfo32 and read System Model. Compare it with the base label and purchase record. If they disagree, use the service tag or serial number on the maker's support page to identify the shipped configuration.
Search that official support page for the product specification and hardware-maintenance manual. You want wording such as two DDR5 SODIMM slots, one onboard module plus one slot, or memory onboard. A maximum figure can apply to the configuration the maker tested rather than every module that may boot, so plan around documented support.

🪟 Use Windows to map what is installed
Open Task Manager, choose Performance and Memory. Note total capacity, speed and Slots used. A reading of one of two suggests a free slot, but firmware can report soldered banks or slot counts in confusing ways. Do not order from that line alone.
A hardware-information tool can show module part numbers, ranks and timings. Match those details with the manual. If software reports one 16GB module and the manual says two SODIMM slots, you have a strong case for one open socket. If the manual says 8GB onboard plus one slot, the same screen needs a different interpretation.
Check whether Windows sees the full installed amount. A machine sold with 16GB but showing 8GB may have a loose module or hardware reservation that needs diagnosis before any upgrade.
🧩 Match the memory the platform can use
DDR4 and DDR5 SODIMMs have different electrical designs and key positions. They are not interchangeable. Desktop DIMMs do not fit laptop SODIMM sockets. Match generation first, then supported speed, capacity per slot and module voltage.
Two matched modules make the cleanest dual-channel arrangement when the laptop has two sockets. A soldered-plus-slot design can still use a broader memory path across matching capacity, with any extra capacity handled according to the platform. The exact behaviour varies, so prioritise stable supported capacity over chasing a label.
Faster memory can run at the laptop's supported speed rather than the number printed on the package. Many laptops do not expose XMP or manual memory tuning. Buy for compatibility with the machine, not for a desktop overclocking profile you cannot enable.
🪛 Check service access before opening the base
Read the disassembly section for screw positions, clip direction and battery disconnection. Some screws stay captured in the cover; others use different lengths. Photograph the base, use a labelled tray and remove the charger before starting.
Warranty terms and upgrade access differ by model and region. Check them before breaking a seal or disturbing internal parts. If the machine is still covered and the memory socket sits beneath the motherboard, professional installation makes more sense than a full strip-down at home.
When you do have safe access, disconnect the internal battery as directed. Release the SODIMM clips, align the module's notch, slide it in at the specified angle and press it down until both clips lock. Do not touch the gold contacts or force a module whose notch does not line up.
Evetech's gaming laptop range provides a current reference when an older soldered-memory design has reached its practical ceiling.
✅ Boot, count and test the new RAM
The first boot can take longer while the firmware trains the memory. Give it time. If the laptop never reaches its logo, shut down, disconnect power and reseat the new module. Restore the original configuration if you need to prove the new part is the cause.
Once Windows loads, check total capacity and speed in Task Manager. Run the built-in memory diagnostic or a dedicated bootable test, then use the laptop through a normal game and sleep-wake cycle. A module that reaches the desktop but throws errors under load is not a successful upgrade.
Keep the original RAM until the new setup has passed. Its part number is also a useful reference if you need to return to the known-good configuration.
Frequently Asked Questions
How do I check if my laptop RAM is soldered?
Use the full model code to find the official specification or service manual and look for onboard or soldered memory wording.
Can a system tool show free RAM slots?
It can report slots used, but firmware data is sometimes misleading. Confirm the result against the model documentation.
Does opening the laptop void the warranty just to check?
Terms differ by model and region. Read the current warranty and service guidance before removing the base.
What RAM type do most upgradeable laptops use?
They use SODIMMs, but the required DDR generation, speed and capacity depend on the exact platform.
Is dual-channel RAM worth confirming before buying more?
Yes. The installed layout helps you choose between adding one module and replacing both with a matched pair.
Does maximum RAM capacity vary by laptop model?
Yes. Processor, firmware, board layout and tested module densities can all set the documented limit.
Should I buy RAM before confirming compatibility?
No. Confirm model, slot layout, DDR generation and supported capacity before placing the order.
Reached the limit of a soldered or single-slot design?
Compare current gaming laptops at Evetech, then check the exact memory layout before deciding between an upgrade and a new machine.
