How Much RAM Should You Buy?
Choose the capacity that fits your workload, pass the compatibility checks, then compare qualified live kits without leaving the site.
Check compatibility before comparing price
1. DDR generation
DDR4 and DDR5 use different slots and are not interchangeable.
2. Form factor
Desktop DIMMs and laptop SO-DIMMs are physically different.
3. Board limits
Confirm maximum total capacity and supported capacity per slot.
4. Matched kit
Prefer one matched kit instead of mixing separate modules.
Quick capacity decision
16GB
Minimum sensible target
Choose this for a budget build when gaming and everyday apps are the heaviest workloads.
32GB
Best default for most buyers
The strongest balance of headroom, current game requirements, and total kit cost.
64GB
Creator and VM upgrade
Worth it when editing, development, local AI, or virtual machines regularly exceed 32GB.
128GB
Workload-driven only
