NOTES:
 Up to 48 GB (4 GB × 12) of DIMMs can be added. (If a water-cooling heat sink is
installed, up to 24 GB (2 GB × 12) of memory can be added.)
 In the error messages and logs in POST, NEC ESMPRO Manager, or Off-line
Maintenance Utility, the DIMM connector may be called group. The number next to a
group meets the connector number in the figure shown above.
Installation
Install a DIMM as described in the following procedure.
IMPORTANT: Due to the interleaving feature, you must always add two identic DIMMs
at a time. The server will not operate if two DIMMs of different specifications are installed
in a group.
1. See the section "Preparing for Installation and Removal" described earlier to prepare.
2. Remove the side cover.
3. Remove the CPU duct cover.
4. Locate the socket where you are going to install the DIMM module.
5. Push the DIMM straight into the socket.
NOTE: Make sure the orientation of the DIMM is correct. The terminal side of the DIMM
has a key to prevent incorrect insertion.
The levers are automatically closed when the DIMM is inserted into the DIMM socket.
IMPORTANT: Always install two DIMMs at a time. In addition, use a set of memory
devices with the same specifications. The specification of a memory device is described on
the label on the module.
6. Install the components you removed earlier.
7. Turn on the power of the server, then make sure that no error message appears during the POST.
If an error message appears, write down the message and look it up in Chapter 8.
8. Start SETUP, then go to [Advanced] → [Memory Configuration]. Make sure that the status of the additional
DIMM is set to "Normal" (see Chapter 4).
9. Set [Reset Configuration Data] on the [Advanced] menu to "Yes".
This is required to update the hardware configuration. See Chapter 4 for details.
10. When a Windows operating system is used, set the paging file size to the recommended value or larger.
Installed memory capacity × 1.5 (See Chapter 5.)
