Price & Performance Comparison

Buying Guide

1. Identify Your Platform

Check your motherboard or laptop manual to see whether it supports DDR4 or DDR5. DDR5 is only available on newer 2024‑25 hardware, whereas most current PCs still use DDR4. If you’re buying for a laptop, the form factor matters – many notebooks use SO-DIMM modules.

2. Decide on Capacity & Channel Layout

For gaming, 16GB is the sweet spot, but creative workloads may benefit from 32GB or more. Dual‑channel kits (two identical sticks) maximise bandwidth; avoid mixing brands or speeds unless you’re certain the board will handle it.

3. Prioritise Speed vs. Price

DDR5 offers higher speeds (up to 6000MHz) but at a premium. DDR4 3200‑3600MHz remains excellent for most tasks and is cheaper. If your budget allows, a DDR5 kit can future‑proof your build.

4. Check Compatibility & BIOS Support

Some motherboards require a BIOS update to recognise the latest DDR5 modules. Verify with the manufacturer before purchasing.

5. Warranty & Support

All listed brands provide at least a 3‑year warranty. Look for retailers offering free returns or extended coverage for peace of mind.
