For AMD Duron, XP, 64-bit
L2 cache by default only uses 256kb unless Celeron/Duron uses 128kb or less.
Windows is optimized for a 256KB secondary cache by default. With most computers now having L2 caches larger than that it pays to take the time to change the setting to correspond to the size of the cache memory installed.
Covers Windows NT/2000/XP/2003 won't take advantage of it.
Under Registry look for:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
Create a new DWORD key:
SecondLevelDataCache
Set in Decimal Notation to your Cache size in Kb
Example P4 Prescott A has 1024kb L2 cache (1MB)
In the Decimal Notation I would type in: 1024
Reboot PC
