CPU Host Frequency:
[By Jumper]: It is recommended to select this option, which will let the CPU
host frequency of this motherboard determined by the jumper-setting.
[Manual]: This allows user to set CPU host frequency manually. However,
because the CPU host frequency of this motherboard is determined by the
jumper-setting, you must set the FSB jumper adjustment according to your
AMD CPU before you use this “Manual” option as the FSB setting in BIOS
setup to perform over clocking. This is not recommended unless you
thoroughly know the feature. Wrong setup may cause problems during
operation.
DRAM Frequency:
If set to [Auto], the motherboard will detect the inserted memory module(s) and
automatically assign appropriate frequency. You may select other value as
the operating frequency: [133MHz (DDR266)], [166MHz (DDR333)],
[200MHz (DDR400)]. Please note that the option [200MHz (DDR400)] will be
available only when K7S41 motherboard is installed.
Flexibility Option: The default value of this option is [Disabled]. It will allow better
tolerance for memory compatibility when it is set to [Enabled].
