Memory Tweaks

Posted by n0nsequitur on January 26, 2008

Although Vista already does a great job managing your computer’s memory, you can custom tailor it to your needs. Open your favorite registry editor and navigate to the following:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management]

There are several keys here that can be changed to customize memory management.

ClearPageFileAtShutdown:
If you are a person who is very concerned with security, this option should be very useful.

  • 0: Inactive pages in the page file are not written with zeros during shutdown. This is the default.
  • 1: The page file will be overwritten with zeros during shutdown. Note that this will increase your shutdown time so use this option only if you absolutely need this kind of security.

LargeSystemCache:
This setting controls the size of the file system cache.

  • 0: This is the default setting. Vista will allocate a standard sized file system cache; usually less than 10MB.
  • 1: This setting will enable Vista’s large file system cache. The cache use all of your system’s ram minus 4MB therefore it is only recommended for use on servers. Do not use this option if you intend to use your system for gaming or other applications. Microsoft notes:

    “When you enable System cache mode on a computer that uses Unified Memory Architecture-based video hardware or AGP, you may experience a severe and random decrease in performance. The Drivers for these components consume a large part of the remaining application memory when they are initialized during startup.”
