Internal PLL Overvoltage [Auto]
This item allows you to enable the internal PLL Overvoltage for K-SKU CPUs to get the
extreme overclocking capability.
Configuration options: [Auto] [Enabled] [Disabled]
BCLK Frequency: DRAM Frequency Ratio [Auto]
[Auto] The BCLK frequency to DRAM frequency ratio is set to the optimized setting.
[100:133] The BCLK frequency to DRAM frequency ratio is set to 100:133.
[100:100] The BCLK frequency to DRAM frequency ratio is set to 100:100.
DRAM Frequency [Auto]
This item allows you to set the memory operating frequency. The configurable options vary
with the BCLK (base clock) frequency setting. Select the auto mode to apply the optimized
setting.
Configuration 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]
[Auto] This option allows you to automatically optimize the CPU Graphics Ratio
depending on the system loading.
[Manual] This option allows you to set a value for an optimal CPU Graphics Ratio.
Use the <+> or <-> keys to adjust the CPU graphics ratio. 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.
Configuration options: [Keep Current Settings] [Ratio First] [BCLK First]
Ensure that you installed an efficient 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.
Configuration options: [Disabled] [Enabled]
