-You may only request the following amount of RAM: <br>
-\*62.5GB <br>
-\*\*187.5GB <br>
-\*\*\*250GB <br>
-\*\*\*\*500GB <br>
-\*\*\*\*\*994GB <br>
-\*\*\*\*\*\*1500GB
+\* Due to overhead for the operating system and hardware, the maximum available memory is lower than the total installed memory. Requesting more may result in your job not running, being delayed, or running on a smaller number of nodes.
