yup, I do. Hi again. First off, I don't have a Dell
computer so I cannot speak with authority here. I can
say that it would surprise me to find out that Dell
purposely disables L2 cache on their systems. That's my
first observation. Secondly, it is typically the system
BIOS that controls whether L2 cache is enabled or
disabled - not the operating system. I have found no MS
documentation (so far) that indicates that this registry
item has any effect on whether or not the L2 cache is
enabled on newer systems. Now it might be possible (I
just don't know for sure) that part of the XP memory
management algorithm is affected interactively if the
system thinks there is no L2 cache. In any event, before
you try to modify the registry in any way, may I suggest
that you run wcpuid.exe, ver. 3x which I believe is still
available here: http://www.h-oda.com/ (ignore prompt for
foreign language support - page will come up in
English). This standalone, no install utility will at
least tell you if the L2 cache exists and is enabled.
Then if you like you can enter the missing key(s) into
the registry. Though I'd be surprised to hear from you
that this has any effect at all on the poor performance
issue. But hey, I'm prepared to be surprised. This is
how mine looks which I believe is pretty much default (XP
Home). I suppose you could copy and paste into three
separate reg documents or combine into one excluding my
numbers (1.),(2.),(3.) Once merged, you can modify
values in the registry. I believe SecondLevelCacheData
takes a decimal value in DWORD.
