I'd expect that such products (at least Bamboo Prevalence) will use virtual memory when necessary, as Windows may allocate more memory than the RAM available when an application asks for it. As for setting the limit for when virtual memory will be used, Bamboo Prevalence does not expose such a setting. Maybe the OS will let you set such limits...!?!?
Have a look at my latest article about Object Prevalence with Bamboo Prevalence.
