Click on “Starting”, “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”

If you have another quantity of RAM, you can find the value added by laying down the following rule:

• If you have 64 MB of RAM or less, to withdraw 7 MB from your quantity of RAM before converting into hexadecimal.
• If have between 64 and 512 MB of RAM, to withdraw 16 MB from your quantity of RAM before converting into hexadecimal.
• If you have more than 512 MB of RAM, to withdraw 16 MB from your quantity of RAM before converting into hexadecimal.

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”.
