Buying Guide

Choose the correct form factor

Match SODIMM for laptops and standard DIMM for desktops to ensure physical compatibility with your device

Match DDR generation and speed

Install the same DDR generation (DDR3 vs DDR4) and check motherboard or CPU-supported speeds like 2400–3000 MHz to avoid instability

Consider capacity and kit configuration

Decide between single modules or matched kits (e.g., 2x8GB) to enable dual-channel performance and meet multitasking needs

Look at CAS latency and timings

Lower CAS latency (e.g., C16) and tighter timings can improve responsiveness, especially in latency-sensitive tasks

Prefer reputable brands and warranty

Choose established memory makers with clear specs and warranty coverage to reduce risk of compatibility issues
