Frequently asked questions
- How much DDR4 RAM do I need?
- For everyday use and light multitasking, 16GB is a comfortable baseline. Heavier gaming or content work benefits from 32GB, though needs vary by application and workload.
- Will DDR4 fit in a DDR5 motherboard?
- No. DDR4 and DDR5 use different physical slots and are not interchangeable. Check your motherboard's specification to confirm which memory type it accepts.
- Should I buy matched pairs of RAM?
- Yes, buying a matched kit and using two or four sticks enables dual-channel operation, which improves memory bandwidth compared with a single module of the same capacity.
