Chapter 2: Getting started
2.5.8 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]
Selecting a very high memory frequency may cause the system to become unstable! If this
happens, revert to the default setting.
2.5.9 Max. CPU Graphics Ratio [Auto]
Allows you to set the CPU Graphics ratio. Use <+>/<-> to adjust the value. The ratio may
vary depending on the system loading.
2.5.10 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 Tuning] [BCLK + Ratio Tuning]
Ensure that you installed an efcient CPU fan for CPU and graphics loading before
selecting either [BCLK + Ratio Tuning] or [Ratio Tuning]. To keep the current
overclocking tuner status, select [Keep Current Settings].
2.5.11 EPU Power Saving Mode [Disabled]
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]
2.5.12 DRAM Timing Control
The subitems in this menu allow you to set the DRAM timing control features. Use the
<+> and <-> keys to adjust the value. To restore the default setting, type [auto] using the
keyboard and press the <Enter> key.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
2.5.13 DIGI+ VRM
CPU Load-Line Calibration [Auto]
Load-line is dened by Intel VRM specication and affects the CPU power voltage. The CPU
working voltage will decrease proportionally depending on the CPU loading. Higher levels of
the load-line calibration can get a higher voltage and a better overclocking performance but
increases the CPU and VRM thermal. Conguration options: [Auto] [Level 1] [Level 2] [Level
3] [Level 4] [Level 5] [Level 6] [Level 7] [Level 8] [Level 9]
The boosted performance may vary depending on the CPU specication. Do not remove
the thermal module.
