Whenever a program is executed on a hosting server, it is loaded into the physical memory. In case you run a resource-demanding script, or if you just add more scripts on your sites and you get a lot of visitors, you may encounter a case where your Virtual Private Server has too little memory to run all the applications and freezes for that reason, which means that your sites will stop working correctly and that the website visitors will start seeing error messages. To avoid this sort of a scenario, you can take advantage of the RAM upgrade that we're offering and increase the amount of physical memory at your disposal without changing the whole plan. This way, you may pay just for the resources you actually need and not for additional disk space or higher CPU speeds that you won't really use, for instance. With the upgrade, you'll be able to ensure the faultless functioning of your websites, which also means a better experience for your website visitors.
