On older machines there is a significant limit to the amount of main memory 
that is cache-able, even if you increase the cache size, due to the TAG RAM 
limitations.  Compaq typically didn't put any extras in their machines.
My desktop until last summer, a Pentium MMX233, had a cache-able RAM limit 
of only sixty-four, yes 64, MB.  Every memory access outside of this range 
would run at main memory speed and latency, NOT at L2 cache speed.

The impact gets more significant as the processor gets faster.  It might 
even be possible that NT uses the non-cached memory first.

- Just a guess.  You can experiment by removing memory.  While you are at 
it, examine the main-boards to determine that they are indeed identical.
