The BIOS – Extreme Tweaker
Going back to the Extreme Tweaker tab there are sure a lot of options and settings you can mess with. First up is the Sync function that enables and disables syncing with the TurboV EVO or RC Tweakit software. CPU Level up at predesignated values depending on your processor and you can select one and it will automatically change all of the values for you.
The Ai Overlcock Turner has 5 different settings: Manual, Auto, X.M.P., CPU Level Up, and ROG memory profile. The CPU configuration has many different setting in it. You can enable and disable hyperthreading here and you can also turn Intel SpeedStep on or off here.
Moving down you have the DRAM frequency, UCLK frequency, QPI link data rate, and the DRAM timing control. In the DRAM timing control page you can set the specific timings for your installed modules.
If you want to increase the stability of your overlcock you can adjust the Differential Amplitude. You are able to adjust the CPU and IOH clock skew settings. You can adjust the Differential Amplitude from 700mV up to 1000mV. The CPU clock skew can be set on auto, normal and set at a delay.
Moving down to the Extreme Engine Digi+ section you can set the Digi+ PWR mode. There are 2 different modes: T-Balanced and X-Power. T-Balanced is auto phase switching (which will dynamically load the phases based on the system/cpu load) this is ideally for normal usage whether it is stock or moderate overclocking. X–Power enables power delivery for the entire phase array and pushes the most current/power for CPU power delivery. It will provide the highest level of power and stability for high level overclocks but will consume the most board level power as well as produce the most VRM heatoutput. Load-Line Calibration has 4 different options: Auto, 0%, 50% and full calibration. CPU Voltage OCP (Over Current Protection) has the option to be turned on or off. The CPU PWM frequency can be changed from auto all the way up to 1000KHz. PWM Frequency is generally best left at Auto as 90% of the time it will provide a range that meets multiple levels of operation whether it be stock, moderate or even heavy overclocking.
Moving down to the voltages you have options for the CPU, CPU PLL, QPI/DRAM Core, DRAM Bus, DRAM REF, IOH, IOH PCIE, ICH and ICH PCIE. You can really push these voltages high.
The OC Profile allows you to save up to 8 different overclocking profiles.
