Parameter	Type	Description
index	number	Index/Identifier of Hacknet Node.
n	number	_(Optional)_ Number of times to upgrade RAM. Must be positive. Will be rounded to the nearest integer. Defaults to 1 if not specified.

**Returns:** boolean True if the Hacknet Node’s RAM is successfully upgraded, false otherwise. ## Remarks RAM cost: 0.5 GB Tries to upgrade the specified Hacknet Node’s RAM n times. Note that each upgrade doubles the Node’s RAM. So this is equivalent to multiplying the Node’s RAM by 2 n. Returns true if the Hacknet Node’s RAM is successfully upgraded n times or if it is upgraded some positive number of times and the Node reaches its max RAM. Returns false otherwise.
