Out of Memory issues

Some time ago one of the Atodesk's technical staff (don't remember his name) had written a long lecture on minimum requirements for 3dsMax. He had inserted a note of the importance of virtual memory settings, but who knows why he did not want to share how to did this. Well, after quick googling I found the answer myself. Today I accidentally came across this Mental Ray blog and I see so there is a topic as well about Windows virtual memory settings.
