Advanced Clock Calibration
Allows you to determine whether to enable Advanced Clock Calibration when using an AMD Black Edition CPU. We recommend that you enhance heat dissipation for the CPU VRM area if you enable this function.
Disabled | Disables this function. (Default) |
Auto | Lets the BIOS to configure the settings to defaults. |
All Cores | Configures Advanced Clock Calibration for all CPU cores. |
Per Core | Individually configures Advanced Clock Calibration for each CPU core. |
Value (All Cores)
This option is configurable only when Advanced Clock Calibration is set to All Cores. Options are:
Value (Core 0), Value (Core 1), Value (Core 2), Value (Core 3)
This option is configurable only when Advanced Clock Calibration is set to Per Core. Options are:
CPU Clock Ratio
Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being used.
CPU NorthBridge Freq.
Allows you to alter the North Bridge controller frequency for the installed CPU. The adjustable range is dependent on the CPU being used.
CPU Host Clock Control
Enables or disables the control of CPU host clock. Auto (default) allows BIOS to automatically adjust the CPU host frequency. Manual allows the CPU Frequency (Mhz) item below to be configurable. Note: If your system fails to boot after overclocking, please wait for 20 seconds to allow for automated system reboot, or clear the CMOS values to reset the board to default values.
CPU Frequency (MHz)
Allows you to manually set the CPU host frequency. The adjustable range is from 200 MHz to 500 MHz.
Important It is highly recommended that the CPU frequency be set in accordance with the CPU specifications.
PCIE Clock (MHz)
Allows you to manually set the PCIe clock frequency. The adjustable range is from 100 MHz to 200 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto)
HT Link Frequency
Allows you to manually set the frequency for the HT Link between the CPU and chipset.
Auto | BIOS will automatically adjust the HT Link Frequency. (Default) |
200 MHz~2 GHz | Sets HT Link Frequency to 200 MHz~2 GHz. |
Set Memory Clock
Determines whether to manually set the memory clock. Auto lets BIOS automatically set the memory clock as required. Manual allows the memory clock control item below to be configurable. (Default: Auto)
Memory Clock
This option is configurable only when Set Memory Clock is set to Manual.
x4.00 | Sets Memory Clock to x4.00. | |
x5.33 | Sets Memory Clock to x5.33. | |
x6.66 | Sets Memory Clock to x6.66. | |
x8.00 | Sets Memory Clock to x8.00. | |
