Description

Specifies the size of the paged pool.

Value Meaning
0 The system calculates an optimal value for this entry based on the amount of physical memory on the computer, and adjusts this value if the amount of memory changes. The system algorithm typically sets the size of the paged pool to slightly less than the amount of physical memory in the computer. This value is optimal for most systems.
Number of bytes Creates a paged pool of the specified size. This overrides the value calculated by the system and prevents the system from adjusting this value dynamically. This setting can degrade performance.

Activation method

You must restart the computer before a change to this value takes effect.

Caution Image Caution

Do not change the value of this entry. The system adjusts this value dynamically based on internal algorithms. Changing this value prevents the system from calculating an optimal value. This is likely to degrade the performance of your system.
