L2 Cache Tweakage
The L2, or second-level, cache, is an integral part of your CPU. However, XP is very shoddy at detecting it, so setting it manually is sometimes necessary. It's easy to do, though, you simply have to navigate to RUN>Regedit>
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\
in the registry and find the value SecondLevelDataCache. You must then adjust it to the value (in kilobytes) of the L2 Cache of your processor.
You should be able to find the L2 Cache value of your processor from its manufacturer.
NOTE: The L2 Cache of your processor should be entered in Decimal mode.
