In case you use a Virtual Private Server for online and offline programs, you may come across a case where they don't work adequately because of lack of physical memory. This can take place if you try to run an application which requires more RAM than the amount your package includes, or in case you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even when you get a powerful plan, this could happen if you add more apps on the web server in the future, and since it's possible that you shall need only more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you'll be able to use without changing your whole plan. This way, you can pay just for the system resources which you really need and you shall be able to avoid errors on your sites caused by deficiency of memory and the inability of the VPS to load the programs.
