Trouble Shooting
Even with PAE enabled, the underlying architecture of the system is still based on
32-bit linear addresses. This effectively retains the 2GB of application space and the
2GB of kernel mode space because only 4GB of addresses are available. However,
multiple processes can immediately benefit from the increased RAM because they are
less likely to encounter physical memory restrictions and begin paging. Additionally,
applications can be modified to use the AWE API to allocate memory outside of the
applications process space, bypassing the 2-GB limit for applications.
