This is the section every overclocker and enthusiast loves. This is where all the overclocking magic takes place. In the top part of the Extreme Tweaker section is where the CPU properties are adjusted. This is where the BUS speed, multipliers and memory straps are set for maximum performance. One of the best features of this board is the Auto Clock feature, or "CPU Level Up" as they call it. This feature takes the CPU you have and designs a safe auto-setting profile for overclocking. There were three settings for the Phenom II X4 955, which were 3.4GHz, 3.6GHz and 3.8GHz.. The system will automatically set the voltages needed for these overclocks and they are benchmark stable with no issues. For the memory, there are four straps that are set as memory speeds. In this case, with the CPU BUS speed at 200MHz, there is an 800MHz option, a 1066Mhz option, a 1333MHz option, and a 1600MHz option. To get more than 1600MHz, you need to overclock the CPU BUS speed, which will in turn raise the strap and push the memory speed further. In addition to memory speed, there are two sub menus that allow you to control the way the memory operates and the timings for the modules, with numerous options for a more precise and stable set of memory.
In the lower part of the Extreme Tweaker section is where the voltages are changed. There are options for the CPU, memory, Northbridge, Southbridge, and Hypertransport. To change the voltages, you just key in the number that you want or type Auto for auto settings. There are even current voltage displays for you to know where you are sitting in reference to where you want to place them. Below the voltages there is a section for you to set memory reference voltages as well as select how you want the LCD POSTER to show debug information, such as in text or POST codes.
Now we can move on to what we have been waiting for, the testing.
