Now let’s compare the mainboards when they are overclocked.

The Gigabyte mainboard falls behind here because it has a memory clock rate of 1600 MHz as opposed to the MSI mainboard's 1866 MHz. On the other hand, the gap is no larger than 4% in our tests. So, although memory speed is an important factor, it doesn't influence a computer's performance much in some applications.

Power Consumption

We performed our power consumption measurements using an Extech Power Analyzer 380803. This device is connected before the PSU and measures the power draw of the entire system (without the monitor), including the power loss that occurs in the PSU itself. In the idle mode we start the system up and wait until it stops accessing the hard disk. Then we use LinX to load the CPU. For a more illustrative picture there are graphs that show how the computer’s power consumption grows up depending on the number of active execution threads in LinX (both at the default and overclocked system settings). The mainboards are sorted in alphabetical order on the diagrams.

The mainboards consume about the same amount of power in default mode but differ when overclocked. MSI mainboards do not support energy-efficient overclocking (they do not lower the CPU voltage in idle mode), therefore the MSI needs more power at low loads than the Gigabyte.
