[. . . ] Configuration options: [Auto]  - 
Allows you to set the uncore ratio of the processor to its possible maximum value. Configuration options: [Auto]  - 
Allows you to set the CPU bus speed to DRAM speed ratio mode.
2. 5. 7
Memory Frequency [Auto]
Allows you to set the memory operating frequency. Configuration options: [DDR3800MHz][DDR3-1066MHz][DDR3-1333MHz][DDR3-1600MHz][DDR3-1866MHz][DDR32133MHz]~[DDR3-3200MHz]
Selecting a very high memory frequency may cause the system to become unstable!If this happens, revert to the default setting.
2. 5. 8
CPU Graphics Max. Ratio is set to its optimized setting depending on the system loading. Use the <+> or <-> keys to adjust the optimal CPU Graphics Max. The frequency may vary depending on the system load.
2. 5. 9 2. 5. 10
GPU Boost [As is] EPU Power Saving Mode [Disabled]
Allows you to enable the GPU Boost to accelerate the integrated GPU for extreme graphics performance. Configuration options: [As is] [Enabled].
Allows you to enable or disable the EPU power saving function. Configuration options: [Disabled] [Enabled]
Chapter 2: Getting started
2. 5. 11
DRAM Timing Control
The sub-items in this menu allow you to set the DRAM timing control features. To restore the default setting, type [auto] using the keyboard and press <Enter>.
Changing the values in this menu may cause the system to become unstable!If this happens, revert to the default settings.
2. 5. 12
CPU Load-Line Calibration [Auto]
Load-line is defined by Intel VRM specification and affects CPU voltage. Higher value gets a higher voltage and better overclocking performance, but increases the CPU and VRM thermal conditions. This item allows you to adjust the voltage range from the following percentages to boost the system performance: 0% (Regular), 25% (Medium), 50% (High), 75% (Ultra High), and 100% (Extreme). Configuration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme]
The actual performance boost may vary depending on your CPU specification.
CPU Fixed Frequency [XXX]
This item allows you to set a fixed CPU frequency. The values range from 200kHz to 350kHz with a 50kHz interval.
CPU Power Phase Control [Standard]
Allows you to set the power phase based on the CPU. Configuration options: [Standard] [Optimized] [Extreme] [Manual Adjustment]
DO NOT remove the thermal module when setting this item to [Extreme] and [Manual Adjustment]. The thermal conditions should be monitored.
This following item appears only when you set the CPU Power Phase Control item to [Manual Adjustment].
Manual Adjustment [Fast] Allows you to set a response for the CPU power phase control. Configuration options: [Ultra Fast] [Fast] [Medium] [Regular]
CPU Power Duty Control [T. Probe]
DIGI + VRM Duty Control adjusts the current of every VRM phase and the thermal conditions of every component. Select to maintain the current VRM balance.
CPU Current Capability [Auto]
Allows you to configure the total power range, and extends the overclocking frequency range simultaneously. Configuration options: [Auto] [100%] [110%] [120%] [130%] [140%]
Choose a higher value when overclocking, or under a high CPU loading for extra power support.
2. 5. 13
CPU Power Management
The subitems in this menu allow you to set the CPU ratio and features.
Enhanced Intel SpeedStep Technology [Enabled]
Allows you to enable or disable the Enhanced Intel® SpeedStep Technology (EIST). The operating system dynamically adjusts the processor voltage and core frequency which may result in decreased average consumption and decreased average heat production.
Turbo Mode [Enabled]
Allows you to enable your core processor’s speed to run faster than the marked frequency in a specific condition. Configuration options: [Disabled] [Enabled]
• • Turbo Mode is only available on selected CPU models only. [. . . ] If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • • • • Reorient or relocate the receiving antenna. Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.
The use of shielded cables for connection of the monitor to the graphics card is required to assure compliance with FCC regulations. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
