Low-Voltage DIMM Considerations
The server can be ordered with low-voltage (1.35 V) DIMM pairs or standard-voltage (1.5 V) DIMM
pairs. Low-voltage DIMM pairs and standard-voltage DIMM pairs can be mixed in the same server. Note
that this causes the system BIOS to default to standard-voltage operation (Performance Mode). That is,
the server cannot operate in the Power Saving Mode unless all DIMM pairs in the server are low-voltage
DIMMs.
There is a setting in the BIOS Setup utility that you can use to change the DDR memory mode when the
server has all low-voltage DIMMs installed. To access this setting, follow these steps:
Enter the BIOS setup utility by pressing the F2 key when prompted during bootup.
Step 1
Step 2
Select the Advanced tab.
Step 3
Select Low Voltage DDR Mode.
Step 4
In the pop-up window, select either Power Saving Mode or Performance Mode.

Step 5
Press F10 to save your changes and exit the setup utility, or you can exit without saving changes by
pressing Esc.

Cisco Systems Supported DIMMs for M2 Servers
Description
4 GB DDR3 1333 MHz RDIMM PC3-10600 single rank/Low Voltage
16GB DDR3 1333 MHz RDIMM PC3-10600 dual rank/ Low Voltage
16GB DDR3 1333 MHz RDIMM PC3-10600 dual rank/ Low Voltage A
16GB DDR3 1066 MHz RDIMM PC3-8500 quad rank/Low-Dual Volt
BIOS package.
Power Saving Mode–Enables low-voltage memory operation. This setting is available only if all
DIMMs installed are low-voltage DIMMs.
Performance Mode–Disables low-voltage memory operation. If you mix low-voltage DIMM pairs
with standard-voltage DIMM pairs, the system defaults to this setting.
