Whether or not you need to configure the computer with these options depends primarily on
the kind of software or peripherals you use.
(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 sub window 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.
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.
