NT Second Level Cache Tweak

Last Updated: 24 March 1998

By default, NT only uses 256K of Level 2 cache per processor. If you have 512K, or more, you might want to tweak your registry to let NT know... If you don't know how much level 2 cache you have, pay attention while your machine is booting.

To do this, run regedt32 from the Start -> Run window.

  8. enter your cache size
  9. close regedt32
