2.4.2 CPU Ratio [Auto]
Allows you to set the ratio between the CPU Core Clock and the FSB Frequency. Use the
<+> and <-> keys to adjust the ratio. The valid value ranges vary according to your CPU
model.
The following two items only appear when you install a 6-core CPU.
AMD Turbo CORE technology [Enabled]
Enables or disables the AMD Turbo Core technology. Conguration options: [Disabled]
[Enabled]
Turbo CORE Ratio [Auto]
Sets the Turbo Core ratio. Use the <+> / <-> keys to adjust the ratio. The valid value ranges
vary depending on your CPU model. Conguration options: [Auto]
2.4.3 DRAM Frequency [Auto]
Allows you to set the DDR3 operating frequency. Conguration options: [Auto] [800MHz]
[1067MHz] [1333MHz] [1600MHz]
Selecting a very high DRAM frequency may cause the system to become unstable! If this
happens, revert to the default setting.
