If you receive a message that the current session's memory usage is approaching the operating system
limit, save your work as soon as possible and restart Revit Architecture. If you are using a workshared
environment, save your local file, restart Revit Architecture, and then save to central.

operating system to improve performance on 32-bit machines.
See
Enabling the 3 GB Feature on 32-Bit Machines
on page 16.
■
Run Revit Architecture on a Windows 64-bit operating system.
■
Reduce the number of loaded DWG and RVT links. See
Managing Links
on page 1222.
■
Reduce the number of loaded RVT and RFA files. See

Close Hidden Windows.
3 GB Feature Considerations
Before deciding to use the 3 GB feature, review the following considerations:
■
This feature is supported only on Windows XP SP2 and Windows Vista running on 32-bit machines.
■
When the 3 GB feature is enabled, your operating system has less memory space. It is not completely
clear what implications this may have on Windows, so be cautious with regard to the total application
load placed on Windows while running in this mode. If you do not require the larger address space, it
is recommended that you do not enable this option.
■
At least one graphics card driver version is known not to work with 3 GB. This is ATI Fire GL 8800, driver
version 6.12.10.3035. If you experience a crash, restart your computer without the /3GB option and
check whether upgrading to the latest graphics card driver resolves the issue.
Enabling the 3 GB Feature on 32-Bit Machines
Revit Architecture is a 32-bit application, which is limited to 4 GB of virtual address space. Typically, on a
32-bit machine, Microsoft
®
Windows
®
reserves 2 GB of the 4 GB virtual address space of any process for the
operating system and leaves the remaining 2 GB for the application process (including the space for the
code pages, the stack, and all dynamically allocated memory). The 3 GB feature divides the virtual address
space differently on 32-bit machines, providing 3 GB for the application and 1 GB for the operating system.
On 64-bit machines, the 3 GB switch does not apply because Windows does not reserve virtual address space
for the operating system, allowing Revit Architecture to use up to the available 4 GB.
Before enabling the 3 GB feature, see
3 GB Feature Considerations
on page 16.
To enable the 3 GB feature on Windows XP
1
Open the boot.ini file.
This file is typically located in C:\boot.ini.
2
In the "operating systems" section, copy the original line containing the boot path, then modify
the copied line to add the option (/3GB) and the display string that identifies the boot option.
An example of the line to copy and the modified version of the line are shown below. The
modified portions of the copied line are in bold.
