Internal PLL Overvoltage [Auto]
This item allows you to enable the internal PLL Overvoltage for K-SKU CPUs to get the
extreme overclocking capability.
Conguration options: [Auto] [Enabled] [Disabled]
BCLK Frequency: DRAM Frequency Ratio [Auto]
[Auto] The BCLK frequency to DRAM frequency ratio will be set to the optimized
setting.
[100:133] The BCLK frequency to DRAM frequency ratio will be set to 100:133.
[100:100] The BCLK frequency to DRAM frequency ratio will be set to 100:100.
DRAM Frequency [Auto]
This item allows you to set the memory operating frequency. The congurable options vary
with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized
setting.
Conguration options: [DDR3-800MHz] [DDR3-1066MHz] [DDR3-1333MHz] [DDR3-
1400MHz] [DDR3-1600MHz] [DDR3-1800MHz] [DDR3-1866MHz] [DDR3-2000MHz] [DDR3-
2133MHz] [DDR3-2200MHz] [DDR3-2400MHz] [DDR3-2600MHz] [DDR3-2666MHz] [DDR3-
2800MHz] [DDR3-2933MHz] [DDR3-3000MHz] [DDR3-3200MHz] [DDR3-3400MHz]
Max. CPU Graphics Ratio [Auto]
Allows you to automatically optimize the CPU graphics ratio or manually set a value for an
optimal CPU graphics ratio. Use the <+> or <-> keys to adjust the value. The minimum value
depends on the installed CPU.
OC Tuner [Keep Current Settings]
This item allows you to automatically overclock the CPU and DRAM frequencies and voltage
for an enhanced system performance. It also accelerates the CPU graphics performance to
the extreme depending on the CPU graphics loading.
Conguration options: [Keep Current Settings] [Ratio First] [BCLK First]
Ensure that you installed an efcient CPU fan for CPU and graphics loading before
selecting either [BCLK First] or [Ratio First]. To keep the current overclocking tuner
status, select [Keep Current Settings].
EPU Power Saving Mode [Disabled]
The ASUS EPU (Energy Processing Unit) sets the CPU in its minimum power consumption
settings. Enable this item to set lower CPU VCCIN and Vcore voltages and achieve the best
energy saving condition.
Conguration options: [Disabled] [Enabled]
