Dynamic Energy Saving: To validate or disprove the energy saving features of the GA-X48-DQ6, I installed the Dynamic Energy Saving software to get started. After the install I was prompted to return the memory speeds and voltages to stock so that the DES software could do its job. The software works in conjunction with the energy saving features of the X38/38/P35 chipsets. Namely the C1E and EIST features, which dynamically lower the core speed and voltage to the processor at off load times. The DES expands on this functionality to further reduce energy consumption. To test the software I will make a comparison of the wattage measured with a KillaWatt meter to test actual wattage consumed at idle and load with the software on and off. I will also show the savings generated by the software at both idle and under load.
In the views of the software in action below, the the effectiveness of the software is painfully obvious to the energy conscious of the world. At Idle, with the software disabled, the CPU alone was pulling 19+ watts from the PSU, and under load this balloons to almost 52 watts. CPU-Z is used to show the power saving and processor throttling.
Now I will run through the same scenario with the DES software enabled. At idle, the processor pulled a whopping 7.9 watts. Under load, the power consumption blossoms up considerably, but at this point the savings is 16 watts! These are pretty substantial numbers from just enabling the software.
The DES software allowed the X48-DQ6 to reduce power consumption at both idle and while under load. The savings at idle amounted to 25 watts measured and 24 watts under load with the meter. This over the long term amounts to considerable savings. The savings measured by the software are pretty incredible. At idle, the difference between with the software on and off was 12 watts, or well over a 100% savings. Under load, the savings were only about 30%. So if the two are averaged, one comes pretty close to the 70% efficiency savings stated in the Gigabyte literature.
