To add RAM to a mini PC, first confirm it has removable SO-DIMM slots rather than soldered memory, buy modules of the right type (DDR4 or DDR5) within the maker’s stated maximum, then power down, unplug, open the case, seat the module at an angle until the clips snap, and confirm the new total in the BIOS or Windows. If the memory is soldered, it cannot be upgraded.

Step 0: Find Out Whether Your Mini PC Can Be Upgraded
Many mini PCs use laptop-style SO-DIMM sticks, but some, especially newer models built around LPDDR5X, solder the memory to the board. Guides from Evetech, Starry Hope and PC Build Advisor suggest looking in the maker’s spec sheet for the words SO-DIMM, soldered, onboard or LPDDR5X. A single model can even come in a soldered edition and a socketed edition, so match the exact model number.
On Windows you can see the installed type in Task Manager under Performance and Memory, which lists speed and the number of slots used. The tab shows form factor (SODIMM or row of chips). On Linux, the command dmidecode with the memory option lists type, speed and slots. If slots read as used with no spare and the maker says memory is soldered, stop here.
What You Need
- The right modules. SO-DIMM, not desktop DIMM. DDR4 and DDR5 are not interchangeable, and the notch position differs.
- Capacity within the limit. Look up the maximum supported memory and maximum speed in the manual or the maker’s support page. Modules faster than supported usually run at the lower supported speed.
- A small screwdriver for the bottom plate screws, and a clean work surface.
- Matched pairs where possible. Two identical modules allow dual-channel mode, which helps integrated graphics performance.
Step-by-Step Installation
- Back up and power off. Shut down Windows fully rather than putting it to sleep.
- Unplug everything. Remove the power adapter and peripherals. Press the power button for a few seconds to drain remaining charge.
- Discharge static. Touch bare metal on the chassis before handling modules. Hold modules by the edges.
- Open the case. Remove the screws on the bottom or lift the cover per the manual. Some models have a latch or a plate that slides off. Take care with any ribbon cables or antenna leads that attach to the lid, and note that opening the case may affect warranty terms on some models, so read the warranty section first.
- Locate the slots. Look for one or two angled slots with a metal clip on each side. A drive bracket or a shield may cover them.
- Remove old modules if replacing. Gently push both clips outward at once. The stick pops up at an angle. Slide it out without touching the gold contacts.
- Align the new module. Match the notch on the module to the key in the slot.
- Insert at an angle. Push it in at roughly 30 to 45 degrees until the contacts disappear.
- Press down. Push the module flat until the clips snap. It takes firmer pressure than you may expect. A module seated but not clipped can cause failed or intermittent starts.
- Close and reconnect. Replace the cover and screws, reconnect power and boot.
- Confirm in the BIOS. Enter setup with the key named in the manual (commonly Del, F2 or F10) and look at the system information page for the total capacity. Menu names vary by maker.
- Confirm in Windows. Task Manager and Settings, then System, then About show installed RAM.
Quick-Reference Table
| Item | What to check | Where to find it |
|---|---|---|
| Memory type | DDR4 or DDR5 SO-DIMM | Spec sheet, Task Manager |
| Soldered or socketed | SO-DIMM listed, or LPDDR5X (soldered) | Maker’s page, teardown guides |
| Max capacity | Total across slots | Manual, support page |
| Max speed | Supported MT/s | Manual |
| Slots | One or two | Task Manager, inside the case |
| Dual channel | Two matched modules | CPU-Z or Task Manager |
What Result to Expect
After a successful install, the BIOS and Windows report the new total. Games and apps that were short on memory should stop swapping to disk, and integrated graphics may gain from dual-channel memory because it shares system RAM. Do not expect a large frame-rate leap if you already had enough RAM for your workload.
Common Mistakes
- Buying desktop DIMMs instead of SO-DIMMs.
- Mixing DDR4 and DDR5 or assuming one can replace the other.
- Exceeding the supported capacity, which can lead to no boot or reduced capacity.
- Leaving the module unclipped, causing intermittent starts.
- Forcing a module that is the wrong way round.
- Touching gold contacts or working without unplugging.
Troubleshooting After the Upgrade
If there is no display, power down, unplug, and reseat each module. Try each module alone, then in the other slot, to find a bad stick or slot. If the system boots but shows half the capacity, a slot may be unseated or the board may cap the memory. A BIOS update from the maker can add support for larger modules, but BIOS updates carry risk, so follow the maker’s instructions and keep power stable. Memory settings in BIOS should stay at default or the stored profile if the module has one; manual overclocking can cause instability and void warranties.
When Not to Do It
Do not attempt the upgrade if memory is soldered, if the maker says opening the case voids warranty and you are still covered, or if you are not comfortable handling small parts. Contact the maker or a technician if the unit has no spare slot, uses unusual hardware, or you hit problems you cannot resolve. Never open the power adapter.
Choosing Capacity and Speed
For a gaming or general-purpose mini PC, 16 GB covers many titles and everyday tasks, while 32 GB gives room for browser tabs, streaming software and background apps together. Mini PCs with integrated graphics share system memory with the GPU, so more memory and a dual-channel pair can both help. Speed matters less than capacity: if your model supports DDR5-5600, a kit rated higher usually just runs at the supported speed. Look at the maker’s memory support page for tested modules where available, and buy a reputable brand with a warranty.
Frequently Asked Questions
How do I know if my mini PC RAM is soldered?
Check the spec sheet for SO-DIMM or LPDDR5X wording, or look inside for angled sticks held by clips. Flat chips fixed to the board with no clips mean it is soldered.
Can I use laptop RAM in a mini PC?
Yes, if it is the same SO-DIMM type and generation. Match DDR4 or DDR5 and stay within the supported speed and capacity.
Do I need two identical sticks?
Not required, but a matched pair enables dual-channel operation, which usually performs better than a single module, particularly for integrated graphics.
Will faster RAM than my mini PC supports work?
Often it runs at the highest speed the system supports. The stated maximum in the manual is the safe limit.
How much RAM should a gaming mini PC have?
Sixteen gigabytes is a common minimum for gaming and 32 GB gives extra room for multitasking, if the model supports it.
Will opening the case void my warranty?
It depends on the maker. Read the warranty page before opening the case, since some allow memory upgrades and some do not.
