SolidWorks only using half of available ram?

When trying to manipulate fairly simple assemblies, my computer slows to a crawl. Looking at the task manager, SolidWorks never uses more than 4 of my available 8 GB of RAM. Is there some setting I need to change to have it use all available RAM?

SolidWorks Version: 2017 Student Edition

Processor: Intel i7-8550U
