We are moving from a 32 Bit PA-RISC processor to 64 Bit Itanium processor based System.
I am aware that 64 Bit processor allows for memory (RAM) addressibility beyond the 4 GB memory (RAM) limit imposed by a 32 bit processor

I have been asked to prove that the new systems are capable of addressing RAM beyond 4 GB

Is there any utility that I can use to prove this or UNIX command or script

Any input / help on this would be great!

Thanks in advance.
