You need to tell us the operating system you are using and how much
memory is installed on the system and how big the data is that you
are working on.

After this info, I predict the answer will be:

- use a machine with more memory
- use a Linux system instead of Windows as it is easier to use more
  memory there.
- use a 64-bit Linux system to use GBs of RAM.

But the real question may be: how can you accomplish your task on a
memory limited system.
