Memory
Choose the right RAM for your platform.
Capacity
Working memory available to the system, measured in GB. Add the capacity of all installed modules.
DDR generation
DDR3, DDR4, and DDR5 require compatible hardware. Desktop DIMMs and laptop SODIMMs also differ.
Speed and latency
Transfer rate describes data movement. CAS latency is measured in clock cycles; consider both rather than treating either as a score.
