Whenever an app is executed on a hosting server, it's loaded into the physical memory. If you run a resource-demanding script, or if you just add more scripts on your sites and you get loads of visitors, you might encounter a case where your Virtual Private Server has not enough memory to run all the applications and freezes as a result, which means that your websites will stop working correctly and that the site visitors will start seeing error messages. To avoid such a scenario, you may take advantage of the RAM upgrade that we are offering and increase the amount of physical memory at your disposal without changing your entire plan. In this way, you'll be able to pay only for the resources that you actually need instead of for additional disk space or higher Processor speeds which you will not really use, for example. With the upgrade, you can guarantee the flawless functioning of your Internet sites, which also means a better experience for your website visitors.
