The BIOS – Ai Tweaker
Now let’s go back into the Ai Tweaker tab, this is where you will find all of the settings for overclocking and really tweaking out your system. You are first shown your target CPU speed and target DRAM speed. In the Ai Overclock tuner you are given 3 options Auto, Manual and X.M.P. If you choose manual a new option set will come up that allows you to adjust the BCLK by all cores.
Moving down to the memory frequency you can set it above the default 1333Mhz, looks like it can go pretty high too as we have the option to go all the way up to 2400MHz! The EPU power saving mode is what it says, it is a way to save power while your system is operating. The OC Turner setting when selected will automatically reboot the system and “auto tune” it for the best overclock. If you go into DRAM timing control you can set the timings for your installed memory.
In the CPU Power management section you can again set the CPU ratio. You can also enable Intel Speedstep and Turbo Mode. Moving down the page you have many of the Digi+ VRM settings, the first is load-line calibration, which can be set on auto or go all the way up to extreme. You also have Phase control settings, duty control settings, and CPU current capability settings, all of which can be changed.
Finally at the bottom of the page you have all of your voltage settings. You can change the voltages for the CPU, DRAM, VCCSA, VCCIO, CPU PLL, and PCH. You are also able to change the CPU spread spectrum.
