in your start bar go to RUN type in REGEDIT then navigate to Memory
management as described below, double click the entry and change the DWORD
value to suit your CPU.

HKEY_LOCAL_MACHINE => SYSTEM => CurrentControlSet => Control => Session
Manager => Memory Management

SecondLevelDataCache
for 256kB Level 2 Cache = 0
for 512kB Level 2 Cache = 200
for 1024kB Level 2 Cache = 400
for 2048kB Level 2 cache = 800

If I recall correctly this works only for L2 cache on the system bus and not for integral L2 cache that has been common since the Pentium 2.

direct-mapped L2 caches. Pentium II and later processors do not have

I was reading about this, and other "recommended" tweaks, when
researching pagefile sizing on a website which pointed out the various
inaccuracies and occasional tweaking myths, but I can't find the site
again for the life of me.....
