RAM quota corresponds to the amount of RAM available in your account. It comes from both shares that are available in your account (not attached to a server) as well as any additional RAM that you may have purchased.

The quantity of RAL allocated to a server cannot exceed 6 GB.

Modify the quantity of RAM allocated to your server during its creation

When you create a server, you will be presented with the quantity of RAM that corresponds to the number of shares that you are going to allocate to your server.

You can:

• attribute less RAM. Quota will be then available for use by other servers, for example.
• attribute more RAM if you have quota available in your hosting account.

Change the amount of RAM on an existing server

On your server's management page, you will see a line that says specifies the amount of RAM associated to your server (it is on the right, in the General Information box). Click on the "Modify" link. You can then change the amount of ram allocated to the server using the dropdown menu.

Which RAM limit should I choose for my VPS ?

The RAM limit should be chose as the maximum of RAM that you may allocate to the VPS.

Flex operations (which allow to increase the server power by adding shares directly in case of a load peak) should have a correct RAM limit before beginning, else the VPS will restart to adapt the RAM limit to apply the changes.

For example, you use a 1-share VPS, you do a Flex operation to add 9 more shares for a total of 10 shares because you want to prevent a high load. If the VPS manages itself the Flex operation, when the operation begins, the RAM limit will be updated and the VPS restarted. To avoid that, configure the RAM limit before doing the Flex operation, doing so, when the operation begins, the VPS won't restart.
