and DIMMs could pass that hardware tester and still fail in a production 
server due to differences in timing, capacitive/inductive signal load, 
etc.   especially sensitive are systems that use dual bank interleaving 
on a single memory bus.

actually, said machines DO exist, known as ATE (Automatic Test 
Equipment) but they cost $1M's
