The amount of physical memory (RAM) required depends on the number of applications run simultaneously, the size and complexity of the opened SolidWorks parts, assemblies and drawings and the types of operations used on those models. 



If physical RAM is exhausted, your system will still continue operating using Virtual Memory, but performance may be seriously degraded and may also eventually lead to system instability.



Determining if there is enough Physical Memory


  1. Start Windows Task Manager or Resource Monitor (Windows 7).
  2. Start SolidWorks, including SolidWorks add-ins, open typical SolidWorks parts, assemblies, drawings, and performing typical SolidWorks operations on the files, along with other applications used in everyday workflows.
  3. Track the physical memory usage in

       Windows Task Manager
       Total and Available values under the Physical Memory (MB) section in the Performance tab
       Resource Monitor
       In Use and Available values under the Physical Memory section



If the Available Physical Memory gets depleted to under 5% (Task Manager), or the Used Physical Memory exceeds 95% of your Total Physical Memory (Resource Monitor), then more RAM is needed.






: If you find that more than 4GB of RAM is needed, a 64 bit Operating System will be needed to make use of any additional RAM. SolidWorks recommends the use of 64-bit Windows 7 with at least 6 GB of RAM.
