How this affects you

Users, especially gamers or those doing intensive tasks like 3D rendering, might experience reduced performance and increased stuttering because their RAM is operating significantly slower than its theoretical maximum bandwidth. A simple BIOS setting change can unlock the full potential of their RAM.
