Buying Guide

Match form factor to your system

Confirm SODIMM for laptops and small-form-factor PCs versus DIMM for desktops to avoid compatibility issues

Choose the right DDR generation

DDR4 modules offer higher performance and broader modern compatibility, while DDR3/DDR3L remains relevant for older systems

Prioritize capacity for multitasking

16GB kits suit most users upgrading for smooth multitasking and light content work; 8GB remains acceptable for basic use

Check memory speed and latency

Higher MHz and lower CAS latency can improve performance in memory-sensitive workloads, but platform support determines real-world gains

Buy matched kits for dual-channel

Paired kits (2x8GB) ensure matched timings and frequencies to enable dual-channel operation and optimal throughput
