Tip: Table 4-9 lists only memory configurations that are considered best practice in
obtaining optimal memory and processor performance. For a full list of supported memory
configurations, see the IBM System x3690 X5 Installation and User Guide or the IBM
System x3690 X5 Problem Determination and Service Guide. You can obtain both of these
