DIMM Idle Power Saving Mode
NOTE: This option is available on select G7 servers.
The DIMM Idle Power Saving Mode option provides the capability to enable or disable power
throttling for the DIMMs installed in the system. Enabling this option allows DIMMs that support
idle power saving features to enter a low power mode when idle. In some applications, this can
reduce overall system power consumption, but may also slightly reduce overall memory performance
due to the increased latency associated with transitions into and out of idle power saving mode.
When disabled, this option prevents installed DIMMs from entering a lower power mode when
idle. Be sure that all installed DIMMs support DIMM idle power saving features before selecting
the Enabled option. Such support has been verified for all HP DIMMs supported on these platforms.
Options include:
•
Enabled (default)
•
Disabled
