Have you ever thought how great it would be if you can adjust the frequency setting on your motherboard under Windows environment and be a real master of your system? Everybody knows that the ratio and frequency setting are key factors to influence the system performance, however, it’s absolutely not an easy task for an amateur to adjust the setting value. On most traditional motherboards, you have to get into BIOS screen for the frequency

and reboot the system again and again. But from now on, you don’t have to surfer the boring stuffs anymore.

With brand-newanduser-friendlyEzClock that AOpen specially designs for his users, you can adjust those important values as you please and think of suitable. Thistailor-madeEzClock allows you to set the voltage and frequency of CPU, VGA, PCI and memory under Windows environment as well as in BIOS setting page; even better, those settings will be displayed realtime. Having this handy EzClock, you can monitor the system when you’refine-tuningthe performance of your system. It provides you detailed and necessary information. Now let’s take a look how it works on utility, BIOS and POST.




How You Adjust the Settings in EzClock Utility

In EzClock utility, you can adjust CPU Front Side Bus (FSB), the voltage and frequency of VGA, AGP, PCI and DRAM. Besides, the CPU related information such as CPU voltage, temperature and CPUFAN rotation speed will also be displayed on this utility.

CPU Color Bars:

The color bar will light on and show different colors as values change. On default values, it will show green.

On the left circle area shows Ratio, FSB and frequency information about CPU. When the values are set to factory default, the light on the top and bottom of the circle will show green and it will vary as you change these CPU settings.

CPU Ratio, FSB and frequency displaying area:

You can adjust CPU FSB here by entering preferred value.

On the right part of the panel is the section that you adjust the settings of VGA, AGP, PCI and memory. To adjust the voltage and clock frequency of those installments, you can press “-“or “+” on corresponding items. The color parts represent the situation of values. The higher value you set, the light on the color bar goes to right and turns red. After finishing those value settings, you can press “S” button on the upper right hand corner to save changes to CMOS.

VGA, AGP, PCI and DRAM Voltage / Clock Area:

Pressing “_” and “+” buttons, you can adjust the voltage and clock frequency values of onboard70 VGA, AGP, PCI and DRAM.

Control buttons:

“_” button allows you to minimize the utility and “X” button to close the utility. Pressing “S” button you can save the changes to CMOS.



On the bottom rectangular panel represents CPU fan speed, CPU voltage and CPU temperature. The three color bars on the right hand side will light on according to operation temperature. Please refer to the picture shown above.

CPU Color Bars:

The color bars will light on according to CPU operation temperature.

CPU Fan, Voltage and Temperature: representing CPU fan speed, CPU voltage and CPU temperature in Celsius and Fahrenheit degrees.

How You Adjust the Settings in BIOS

Apart from EzClock utility, the voltage and frequency values of CPU, PCI and memory can also be adjusted on BIOS page. By pressing “+”, “-“,“PgUp” or “PgDn” keys, you can adjust the frequency values of CPU Bus, PCI Bus and DRAM.

Also, the same keys help you adjust the voltage of CPU and DDR settings. Some values may change while you adjust the settings. You can press “F10” to save the changes you’ve made.

How Your Boot Screen Looks Like


After you finish setting BIOS, these setting values will be displayed on the boot screen like the shown picture here.

Every time you boot your system, both default and current settings will pop up on the screen. Your personal settings that had been adjusted earlier will be highlighted; thus, you can have clear idea how your system functions and monitor your system more easily.
