Whetherthesystemwillworkstablywiththeoverclock/overvoltagesettingsyoumadeisdependent
onyouroverallsystemcongurations.Incorrectlydoingoverclock/overvoltagemayresultindamage
to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced
users only and we recommend you not to alter the default settings to prevent system instability or
other unexpected results. (Inadequately altering the settings may result in system's failure to boot. If
this occurs, clear the CMOS values and reset the board to default values.)

& CPU Upgrade
 AllowsyoutosettheCPUfrequency.ThenalresultmayvarydependingontheCPUused.Optionsare:
Default,GamingProle,Advanced.(Default:Default)
& CPU Base Clock
 AllowsyoutomanuallysettheCPUbaseclockin0.01MHzincrements.(Default:Auto)
Important: It is highly recommended that the CPU frequency be set in accordance with the CPU
specications.
& PVD Ratio Threshold Override
(Note)
Allows you to determine whether to improve performance under extreme BCLK OC by reducing a "PLL
Banding" condition caused in part by a very high DCO frequency. (Default: Auto)
& PCIe/DMI/PEGClockFrequency
 AllowsyoutomanuallysetthePCIe/DMI/PEGfrequenciesin0.01MHzincrements.
& Enhanced Multi-Core Performance
Determines whether to allow the CPU to run at Turbo 1C speed. (Default: Auto)
& CPU Clock Ratio
Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU
being installed.
& Ring Ratio
Allows you to set the CPU Uncore ratio. The adjustable range is dependent on the CPU being used. (Default:
Auto)
& IGPRatio
(Note)
Allows you to set the Graphics Ratio. (Default: Auto)
