`` M.I.T. Current Status This screen provides information on CPU/memory frequencies/parameters. `` Advanced Frequency Settings && BCLK/PCIe Clock Control Enables or disables the control of CPU base clock and PCIe bus frequency. Enabled will allow the Host Clock Frequency and Processor Base Clock items below to be configurable. Note: If your system fails to boot after overclocking, please wait for 20 seconds for automated system reboot, or clear the CMOS values to reset the board to default values. (Default: Disabled) && Host Clock Frequency Allows you to manually set the host clock frequency (which controls CPU, PCIe, and memory frequencies) in 0.01 MHz increments. This item is configurable only when BCLK/PCIe Clock Control is enabled. When you change the Host Clock Frequency setting, the Memory Frequency (Mhz) setting below will be changed synchronously. Important: It is highly recommended that the frequency be set in accordance with the CPU specifications. && Processor Base Clock Allows you to configure the Processor Base Clock by multiplying the Host Clock Frequency by several preset host clock multipliers. This item is configurable only when BCLK/PCIe Clock Control is enabled. When you change the Processor Base Clock setting, the Memory Frequency (Mhz) setting below will be changed synchronously. Important: It is highly recommended that the frequency be set in accordance with the CPU specifications. && CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being installed. && CPU Frequency This value is determined by multiplying the Processor Base Clock value by the CPU Clock Ratio value. BIOS Setup - 38 -

M.I.T. Current Status
`
This screen provides information on CPU/memory frequencies/parameters.
BCLK/PCIe Clock Control
&
Enables or disables the control of CPU base clock and PCIe bus frequency.
Enabled
will allow the
Host
Clock Frequency
and
Processor Base Clock
items below to be configurable. Note: If your system fails
to boot after overclocking, please wait for 20 seconds for automated system reboot, or clear the CMOS
values to reset the board to default values. (Default: Disabled)
Host Clock Frequency
&
Allows you to manually set the host clock frequency (which controls CPU, PCIe, and memory frequencies) in
0.01 MHz increments. This item is configurable only when
BCLK/PCIe Clock Control
is enabled. When you
change the
Host Clock Frequency
setting, the
Memory Frequency (Mhz)
setting below will be changed
synchronously.
Important:
It is highly recommended that the frequency be set in accordance with the CPU specifications.
Processor Base Clock
&
Allows you to configure the
Processor Base Clock
by multiplying the
Host Clock Frequency
by several
preset host clock multipliers. This item is configurable only when
BCLK/PCIe Clock Control
is enabled.
When you change the
Processor Base Clock
setting, the
Memory Frequency (Mhz)
setting below will be
changed synchronously.
Important:
It is highly recommended that the frequency be set in accordance with the CPU specifications.
CPU Clock Ratio
&
Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU
being installed.
CPU Frequency
&
This value is determined by multiplying the
Processor Base Clock
value by the
CPU Clock Ratio
value.
