Memory requirements depend heavily on your project size and configuration. The smallest Sinolta project will require 1 GB (in addition to the OS). The biggest user of memory is the Sinolta Historian. You will need to perform some bench tests to decide how much memory you need. As a general guideline, plan for 4GB RAM for systems with up to 5,000 points. 8GB RAM for systems with up to 20,000 points and so on.
