Why Upgrade Your Laptop RAM?
Adding RAM is the most cost-effective laptop upgrade. Going from 8GB to 16GB or 32GB dramatically improves multitasking, reduces lag when switching between apps, and eliminates the sluggishness caused by Windows swapping data to disk.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
