Frequently asked questions
- Can I upgrade the RAM in any laptop?
- No. Many thin laptops have memory soldered to the board and cannot be upgraded. Check your model's specification or service manual before buying SO-DIMM modules.
- How do I know which SO-DIMM type my laptop uses?
- Look up your laptop model's specification, which lists DDR4 or DDR5 and the supported speed. Existing module labels or system tools can also confirm the type fitted.
- Is it better to fill both memory slots?
- Generally yes. Using two matched modules enables dual-channel mode, improving bandwidth, though a single module can be a stepping stone if a slot is currently free.
