Setting Maximum Memory Bus Frequency

Configure the system to run memory at a lower maximum speed than that supported by the installed

processor and DIMM configuration. Setting this option to Auto configures the system to run memory

at the maximum speed supported by the system configuration. Configure this option only when HP

Power Profile is set to Custom.

To set the maximum memory bus frequency:

1. From the System Utilities screen, select System Configuration→BIOS/Platform Configuration

(RBSU)→Power Management→Advanced Power Options→Maximim Memory Bus Frequency

and press Enter.

2. Select one of the following options:

• Auto (default)

• 1333MHz

• 1066MHz

• 800MHz

3. Press F10 to save your selection.

NOTE: Options vary depending on the installed processor.

Setting Channel Interleaving

Modify the level of interleaving for which the memory system is configured. Typically, higher levels

of memory interleaving result in maximum performance. However, reducing the level of interleaving

can result in power savings. Configure this option only when HP Power Profile is set to “Custom.”

To set channel interleaving:

1. From the System Utilities screen, select System Configuration→BIOS/Platform Configuration

(RBSU)→Power Management→Advanced Power Options→Channel Interleaving and press

Enter.
