L2 cache

This item is obsolete. On all modern systems, that is all supported processors/systems, it should not be an issue. This is not related to the hardware; it is only useful for computers with direct-mapped L2 caches. Pentium II and later processors do not have direct- mapped L2 caches.

If you have more than 256K of L2 cache, NT may not be using all of it. To correct this:

Key: SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement
Name: SecondLevelDataCache
Value: 0 default for for 256KB of L2 cache

If you have more cache, adjust the value by double-clicking SecondLevelDataCache to bring up DWORD editor. Click Decimal. Enter the amount of L2 cache you have and click OK.
