DDR4 vs DDR5 compatibility
DDR4 and DDR5 DIMMs have different electrical designs and are not interchangeable even when capacities appear similar.
Key things to check
- Motherboard determines RAM generation
- CPU platform also matters
- Do not force a DIMM
Why it matters for gaming
PC performance is the result of several components working together. Frame rate, frame-time consistency, loading, temperatures and upgrade compatibility can all be affected by the surrounding system. Use this guide as a starting point, then verify the specifications for your exact hardware.
Before you buy or change anything
Check the exact model numbers in your PC, read the motherboard and component documentation, and pay attention to FrameForecast compatibility warnings. A faster component is only a useful upgrade when the platform can safely support it and it improves the workload you actually care about.
