Diagnosing a PC performance issue can be tricky, especially if you suspect memory is involved. Chances are, you’ve heard the advice of “just add more RAM”, which is a blanket fix that’s as old as PC hardware. It’s been around since the days of XP, and it’s not entirely incorrect. Modern systems are far better at managing memory than they used to be, and adding more RAM often does little unless you’re running into specific bottlenecks. Heavy multitasking and professional workloads require boatloads of memory; if your PC is used for more than just gaming, you might need to add a couple of sticks to your system.
