What would be a good setting to free memory on linux? I have 8GB but gets used up so fast.

current settings:
kernel.sched_min_granularity_ns = 10000000
kernel.sched_wakeup_granularity_ns = 15000000
vm.dirty_ratio = 40
kernel.pid_max = 4096
vm.bdflush = 100 1200 128 512 15 5000 500 1884 2

What settings would I need so linux frees old ram faster?
