If you are a Windows Vista User, then this tweak is for you.

Click on “Start Button”, “Run…” then type “regedit” and click on “OK”

Go to the key: “HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Session Manager Memory Management ”

Create or modify value DWORD “IoPageLockLimit” and enter one of the following values (into hexadecimal) according to the quantity of your RAM:

• For 128 MB of RAM: “0001C000”
• For 256 MB of RAM: “0003C000”
• For 512 MB of RAM: “00070000”
• For 1024 MB of RAM: “000F0000”

Example for 192 MB of RAM:

• 192 – 16 = 176 (subtraction of the quantity of RAM)
• 176 * 1024 = 180224 (conversion into kilobytes)
• 180224 = 2C000 (conversion into hexadecimal)

To convert into hexadecimal, open the computer of Windows, in the TAB “Posting” select “Scientific”. Check that “Decimal” is selected then type your number. It is enough for you to select “Hexadecimal” to convert the number.

The value which it is necessary added is thus “0002C000”.
