 hashGainRate() Netscript Function
 ==========================================
 
-.. js:function:: hashGainRate(level, ram, core[, mult])
+.. js:function:: hashGainRate(level, ramUsed, maxRam, core[, mult])
 
     :RAM cost: 0 GB
     :param number level: level of the server.
-    :param number ram: ram of the server.
+    :param number ramUsed: ram used on the server.
+    :param number maxRam: max ram of the server.
     :param number core: cores of the server.
     :returns: Money per second that a server with those stats would gain per second.
