The value is specified in Megabytes. Each UGX or AGX G
16 MB shareable system space. The shareable 16 MB are made visible to the CPU through the mapping windows
reserved as specified by the MappingCache registry setting.
If other drivers need a lot of system pages or if they are forced to do so by applications there are two possibili-
ties to make the necessary space available.
On the one hand you can change the set value for the system pages to a sufficient large value. The system pages
entry can be found in the registry under the following path:
HKEY-LOCAL-MACHINE
\System
\CurrentControlSet
\Control
\Session Manager
\Memory Management
\SystemPages
The table below list depending on the operation system the amount of a sufficiently large value for the system
pages.
Operating System
Windows 2000
Windows XP
On the other hand you can decrease the value for the MappingCache. This can lead to a small loss of perform-
ance for some graphic operations.
