FillRam: RAM Stress Test

Fill RAM and see how Android responds to memory pressure. With FillRam's RAM stress test, you choose a target, increase the load gradually, and watch RAM and swap usage in real time. No root required.

Fill RAM to a target

In Fill mode, set a target percentage for physical RAM usage and choose a Light, Balanced, or Aggressive profile. Watch available RAM, memory allocated by FillRam, swap usage, and low-memory status as the load increases.
