There is one familiar tool called Intel Desktop Utility in the software suite provided with the DX58SO2 mainboard. It is neither remarkable nor particularly useful.
It knows some basic facts about your system and helps monitor its temperatures, voltages and fan speeds. When any value goes beyond an acceptable limit, the utility issues a warning message.
The new Intel Extreme Tuning Utility is far more interesting. Its window takes up the whole screen by default. Although you can make it smaller, the utility really has a lot of information to tell you, making the full-screen mode most appropriate.
Detailed system information (about the CPU, memory, graphics card, and the mainboard itself) is displayed at the top of the program window. At the bottom you can see a customizable graph with key monitoring parameters. By the way, you can minimize the window so as to leave only the bottom section visible.
This utility allows changing nearly all of key system parameters such as frequencies, multipliers, voltages, memory timings, and fan speeds. Adjustable values are highlighted in a different color. To apply most of the settings you have to reboot the system. After that, you can use this utility to test the CPU, memory and graphics subsystem (if it’s made by Intel) for stability and save the settings into a profile.
We like this Extreme Tuning utility as it seems to have high potential. It even offers some functions, which you cannot find in the mainboard BIOS like finer tuning of the fans rotation speeds. On the other hand, some important options are missing, for example CPU power-saving modes (the so-called C-States) or the technology for counteracting the CPU voltage drop under load.
