    Barton L2 Cache Optimisation

    Apparently Windows XP by default does not recognize the Barton chips as having 512k L2 Cache. Here’s a little registry tweak to fix it!

    Go to:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement.

    Find the DWORD entry: SecondLevelDataCache. If entering it as hexadecimal 256KB = 100 and 512KB = 200 in hexadecimal, and so on.

    Hope this helps

    It looks like it just how windows uses the cache
    The OS however uses the actual cache size to adjust the memory allocation policy for internal data structures, so as to increase the odds that recently-referenced stuff will stay in the cache.
