(a) CPU Cache Use this option to enable or disable the CPU cache. Enabled Enables the CPU cache. (Default) Disabled Disables the CPU cache. When enabled is selected, a subwindow similar to the one below is displayed to select the cache write policy. The options for this setting are Write-back (default) and Write-through for CPU cache. OPTION Write policy = Write-back Write-back policy provides better system performance, because main memory is accessed only when necessary to update the cache contents with changes in main memory. Write-through policy accesses main memory every time data is handled by the processor. (b) Level 2 Cache Use this option to enable or disable the level 2 cache. When "CPU Cache" is set to "Disabled", this option is not displayed. Enabled Enables the level 2 cache. (Default) Disabled Disables the level 2 cache.

When the computer is in use, the CPU power consumption and clock speed are automatically switched when necessary. (Default) Always High Disables Intel SpeedStep technology and always runs the processor at its fastest speed.
