Configuration options: [Optimal] [Normal] CPU Vcore Setting [Auto] In JumperFree mode, this field allows you to select the core voltage supplied to the CPU. Leave on [Auto] to use the CPU default setting. If you want to set it manually, select [User Define], go to the subsequent CPU Vcore field, and refer to your CPU documentation to make the configuration. CPU Level 1 Cache, CPU Level 2 Cache [Enabled] These fields allow you to choose from the default of [Enabled] or choose [Disabled] to turn on or off the CPU's Level 1 and Level 2 built-in cache. Configuration options: [Disabled] [Enabled] CPU Level 2 Cache ECC Check [Disabled] This function controls the ECC capability in the CPU level 2 cache.
