Free yourself from memory constraints with 64-bit computing
With the widespread availability of 64-bit computers, you can
now take advantage of greater processing power and memory.
Such computers process larger blocks of information at a time and can directly address more memory
than their 32-bit predecessors.
For exceptionally large datasets, the more memory you can access, the
better. With 64-bit Stata software, you can maximize your 64-bit system's
potential and say goodbye to the old 2-GB memory barrier
imposed by 32-bit systems. You are limited only by the
total amount of memory on your machine.
In addition to accessing more memory, 64-bit Stata processes larger datasets more
efficiently, making 64-bit Stata faster than 32-bit Stata.
For example, see the results for the sort and regress commands below.

What kind of performance increase can I expect in going from 32-bit to
64-bit Stata? and our list of supported platforms.
64-bit Stata requires both a 64-bit computing platform and a 64-bit operating system.
