This sounds like a bug in the Landmark code that was fixed in version 1.1x;
systems using page-interleave memory would execute the benchmark at different
speeds depending on WHEREin physical memory the code was actually loaded.
(i.e. on a bank boundary or not). Welcome to the world of benchmarks.
Is this what you bought your computer to run? :-)
