To make Windows XP use L2 cache

[presh4u]

By default windows doesn't recognise your L2 cache on processor and doesn't make use of it, to enable it run regedit and navigate to
HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Session Manager > MemoryManagment
there is a DWORD called "SecondLevelDataCache" double click it, select Decimal and set the amount of L2 cache you have (e.g. if you have 256KB, then just type 256, and make sure you enter it in Decimal, not Hexadecimal

hmm fail, epic fail. Unless, or curse, you really are running half-life 2 on a Pentium or 80486 based PC with more than 64mb of memory. In which case - nice tip, thanks.
