Description:
On windows, the number of page table entry for the virtual memory tables is set in the registry. The number of page table entries in the registry has to be increased to enable the mapping of a large memory range and the amount of available virtual memory is increased. This tweak can define the number of system page table entries that are reserved for mapping i/o buffers and other information. For this, go to start > run menu, enter regedit and navigate to the registry path listed below. Now, right-click and modify the dword value systempages, in the right panel, to any value given in the below table: <table><tr><td>hexadecimal value</td><td><center>description</td></tr><tr><td><center>0</td><td><center>system calculates page table entries</td></tr><tr><td><center>1-fffffffe</td><td><center>specifies the number of reserved page table entries</td></tr><tr><td><center>ffffffff</td><td><center>maximize system pages</td></tr></table> however, if you want to revert to the original state, change the value to default data c3000 as hexadecimal value. The changes take effect after a restart or logoff.
