2.5.8 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] 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. Configuration options: [Keep Current Settings] [Ratio Tuning] [BCLK + Ratio Tuning] Ensure that you installed an efficient 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. Configuration 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 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 defined by Intel VRM specification 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. Configuration 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 specification. Do not remove the thermal module. 2-22 Chapter 2: Getting started
