❓ What Is High RAM Usage?

RAM stores data for active programs, background tasks, and Windows services. Under normal conditions, idle RAM usage should stay around 20%–40%.

If your system uses 70%–100% RAM when nothing is running, you have a high memory usage issue.

❓ Is 100% RAM Usage Good?

No — 100% RAM usage is NOT good.

When RAM hits 100%:

• Apps freeze
• Games lag
• Browser tabs crash
• Windows slows down drastically
• SSD/HDD overworks (due to pagefile usage)
• The system may show blue screen errors

❓ What Happens If RAM Hits 100%?

When RAM reaches 100%, Windows starts using your storage drive (pagefile), causing:

• Severe slowdowns
• System freezes
• App crashes
• Shorter SSD lifespan

So it’s critical to fix 100% RAM usage immediately.
