Extending Your Usable Address Space and Adding
RAM for Improved Performance (Windows)
The Microsoft Windows XP and Vista 32-bit operating systems limit every program to
2 gigabytes (GB) of address space. It reserves the remaining 2 gigabytes of address space for
its own use. The operating system includes a boot-time mechanism that allows applications
access to a larger virtual address space than was previously available. Avid provides a utility
for setting the boot-time mechanism to extend the process address space.
For Microsoft Windows XP and Vista 64-bit operating systems, applications are allocated an
address space well beyond the 2-gigabyte limit allocated by the 32-bit operating systems.
No utility is needed to tell the 64-bit operating systems to allocate additional memory for the
applications.
Setting your Avid editing system to access a larger virtual address space might improve
working with HD projects without running out of memory. Even though you might gain
more memory space, this can be quickly consumed with bins and complex HD effects. For
best performance, if you choose to extend your address space beyond 2 gigabytes, you
should install an additional 1 or 2 GB of RAM.
Using Install3GB.exe to Extend Your Usable Address Space
It is not necessary to run this executable on Vista 64 systems. Perform this procedure on
Vista 32 systems or Windows XP systems.
To extend the application address space:
1. Double click the Install3GB.exe file in the Utilities\3G folder where the Avid
application is installed.
A window opens. You must have administrative privileges to run this utility.

The hardware and software configuration you are running, Nitris DX, Nitris, Adrenaline,
and so on, determines the amount of memory you should allocate for the application address
space.
2. Type the amount of memory you want to allocate for the application space at the
prompt. The recommended settings are:
- 2700 for Mojo and Adrenaline
- 2700 for Mojo DX and Nitris DX
- 2500 for Symphony Nitris Classic
- 2700 for Software Only systems
