I have a Northwood processor with 512 of level 2 cache memory. When I look
into regedit ->
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SesionManager/MemoryManagement
-> DWORD SecondLevelDataCache , the cache is "0". why the
SecondLevelDataCache is not "512". have I to change it by "512"

Detailed Explanation of SecondLevelDataCache
http://support.microsoft.com/kb/183063

"SecondLevelDataCache records the size of the processor cache, also known as
the secondary or L2 cache. If the value of this entry is 0, the system
attempts to retrieve the L2 cache size from the Hardware Abstraction Layer
(HAL) for the platform. If it fails, it uses a default L2 cache size of 256
KB. If the value of this entry is not 0, it uses this value as the L2 cache
size. This entry is designed as a secondary source of cache size information
for computers on which the HAL cannot detect the L2 cache."
 
That doesnt always dictate the amount running on the OS,for specific details
download the "processor identification utility" from intel,the utility will
give
you all running info for it...
