Maximum Memory Bus Frequency
When Power Profile is set to Custom, use this option to configure the system to run memory at a lower
maximum speed than that supported by the installed processor and DIMM configuration. Auto enables
memory to run at the maximum speed supported by the system configuration.
Setting the maximum memory bus frequency
Prerequisite
Power Profile is set to Custom.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power Management > Advanced Power Options > Maximum Memory Bus Frequency and
press Enter.
2. Select a setting and press Enter.
a. Auto—Memory runs at the maximum speed supported by the system configuration.
b. 1333MHz
c. 1066MHz
d. 800MHz
3. Press F10.
Channel Interleaving
When Power Profile is set to Custom, use this option to enable or disable a higher level of memory
interleaving. Typically, higher levels of memory interleaving result in maximum performance. However,
reducing the level of interleaving can result in power savings. Enabled enables the highest level of
interleaving for which the system memory is configured.
When you are enabling NVDIMM-N Memory Interleaving, then you must also enable Channel interleaving.
Enabling or disabling channel interleaving
Prerequisite
Power Profile is set to Custom.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Power Management > Advanced Power Options > Channel Interleaving and press Enter.
2. Select a setting and press Enter.
a. Enabled—Enables the highest level of interleaving for which the system memory is configured.
b. Disabled—Does not enable memory interleaving.
