View Full Version : wWhat does virtual memory mean in this case?

07 July 2012, 01:16 PM
On The Foundry Mari system requirements page, they have this note:

"Virtual Memory Requirements

It is recommended that virtual memory be available for MARI to use, especially when handling large projects. The use of virtual memory improves stability, helping to prevent data loss on large projects." (

I guess I should know this, but what does this mean as far as my system goes? Do they just mean system RAM?

Virtual memory is what the system will use if it runs out of physical memory. Depending on your operating system it might be called swap. Typically this means writing data to the hard disk (or SSD) temporarily as if the disk were memory. In a perfect world virtual memory would never be needed because there would be sufficient physical memory but that isn't the reality.

If no virtual memory is available when the physical memory runs out things will simply crash and not in a controlled way that might automatically save something last second. By default every modern operating system will have some sort of virtual memory setup. That warning from The Foundry is mostly for the users who disable the virtual memory because they think running a system without virtual memory is somehow faster or more stable (which it isn't).

Now I know what this means, something I've always wondered about. Thanks.
