Chapter 2: BIOS information
FSB / CPU External Frequency Synchronization
FSB Frequency [xxx]
Displays the frequency sent by the clock generator to the system bus and PCI bus. The
value of this item is auto-detected by the BIOS. Use the <+> and <-> keys to adjust
the CPU frequency. You can also type the desired FSB frequency using the numeric
keypad. The values range from 200 to 800. Refer to the table below for the correct
Front Side Bus and CPU External Frequency settings.
Overclock Options [Overclock 5%]
Allows you to select the overclock options. Configuration options: [Overclock 5%]
[Overclock 10%] [Overclock 15%] [Overclock 20%] [Test Mode]
DRAM Frequency [Auto]
Allows you to set the DDR3 operating frequency. Configuration options: [Auto]
[DDR3-602MHz] [DDR3-802MHz]

Selecting a very high DRAM frequency may cause the system to become unstable! If this
happens, revert to the default setting.
PCI Express Frequency [Auto]
Allows you to adjust the PCI Express frequency. The values range from 100 to 180.
DRAM Timing Control [Auto]
When this item is set to [Auto], the DRAM timing parameters are set according to the DRAM
SPD (Serial Presence Detect). When set to [Manual], you can manually set the DRAM timing
parameters through the DRAM sub-items. Configuration options: [Auto] [Manual]
CPU Over Voltage [Auto]
Allows you to adjust the CPU over voltage or set
to Auto for safe mode. Press <+> / <-> to
adjust the value. Configuration options: [Auto] [Max.=0.6300V] [Min.=0.0100V]
NB Over Voltage [Auto]
Allows you to adjust the Northbridge Chipset over voltage or set to Auto for safe mode. Press
<+> / <-> to adjust the value. Configuration options: [Auto] [Max.=1.49375V] [Min.=1.10000V].
