Step 4 Check the Memory Module.

Ensure that the memory is present and seated
firmly in the DIMM socket.

Note: For more information about supported memory,

contact Technical Support. Refer to the
Technical Support section in this document for
contact information.

Step 5 Install the RAID Controller.

Install the MegaRAID 320-2X in a 3.3 V PCI or
PCI-X slot, as shown in Figure 2. Press down
gently, but firmly, on the top edge of the card to
seat the card properly in the slot. The bottom
edge of the controller card must be flush with the
slot. Attach the MegaRAID 320-2X to the
computer chassis with the bracket screw.

If your board has a memory module, never apply
