Thank you Brian.  I booted from the install DVD and typed memtest86
at the "boot:" prompt.

It reported memory error as you suggested, somewhere around the 1.5GB
mark for certain tests.  I tried running the memory slower (lowered to
667MHz down from 800MHz via BIOS settings), but it still erred out.
The memory is going back to the store, and I will be testing all memory
in this manner before deployment.

Best regards,
