Question Need to release Cache memory

Right now i am using Red Hat Enterprise Linux AS release 4 and cache memory occupying around 1.5GB mentioned below,

Code:
            total       used       free     shared    buffers     cached 
Mem:   2026       2021          5          0        161       1477 
-/+ buffers/cache: 382       1644 
Swap:  4094          0       4094

I have tried
Code:
sync; echo 3 > /proc/sys/vm/drop_caches
