ASUS UEFI Steps ContinuedCPU Power Duty Control - This setting controls phase array loading policies. When set to default operation of T.Probe the phase array will complete loading based on avg temp distribution, this is done to help minimize hot spotting of the VRM and overall provide more balanced temperatures across the VRM. This setting does not affect phase switching polices. For overclocking up to 4.6-4.8GHz depending on voltage required the T.Probe vsetting will ensure sufficient current delivery. For 4.7GHz + it may be recommended to switch to Extreme this will change distribution policy from temperature to current ensuring highest current delivery. Be advised this setting will produce more heat for the VRM and increase total system power consumption. It is advised this setting be used only when airflow is present for the VRM heatsink assembly. * Cooler operation of the VRM ensures superior efficiency and maximum current delivery under either setting.
CPU Power Phase Control - This setting controls phase switching policies for idle and moderate load. When set to default operation of standard phase switching will be 1 to 4 phase, optimized will default switching operation to 1,2,4,6 onward in increments of 2 until maximum phase count is reached. Extreme will force phase switching to no longer be active and maximum phase array will be enabled at idle and full load. Regardless of defined parameter once under full load phase switching will put maximum phase array under load. The general recommendation for this setting is optimized for most situations and for moderate overclocking as well. This setting generally will provide fast enough response and power delivery up to 4.8GHz. This setting should ideally be matched with considerations for LLC, C States and Vid options (manual or offset). Such as an overclock of 46x should ideally use an offset voltage, with T.Probe loading policy and a phase control setting of optimized or standard. In addition if all C states should be active and LLC should be disabled this would provide a good mix of increase performance but minimized thermal increase (at idle, moderate load and full load) as well as less consistent voltage being supplied to the CPU. Be advised this setting (when set to extreme) will produce more heat for the VRM and increase total system power consumption depending on which option is selected. It is advised this setting be used only when airflow is present for the VRM heatsink assembly. * Cooler operation of the VRM ensures superior efficiency and maximum current delivery under either setting.
DRAM Current Capability - This option is key an ensuring OCP trigger point is not hit when overclocking as well as heavily loading memory. This value needs to be defined dependent on the load of applications and potential stress tests. Overall a recommended % is 120% this should allow for stability under heavy memory load for frequencies exceeding 1866 and voltages higher than 1.65 it is advised to consider 130%.
DRAM Power Phase Control - This setting controls phase switching policies for idle and moderate load. Extreme will force phase switching to no longer be active and maximum phase array will be enabled at idle and full load. Regardless of defined parameter once under full load phase switching will put maximum phase array under load. The general recommendation for this setting is optimized for most situations and for moderate overclocking as well. This setting generally will provide fast enough response and power delivery up to1600 and possibly 1866. This setting should ideally be matched with considerations for LLC, C States and Vid options (manual or offset). Such as an overclock of 46x should ideally use an offset voltage, with T.Probe loading policy and a phase control setting of optimized or standard. In addition if all C states should be active and LLC should be disabled this would provide a good mix of increase performance via increased frequency but minimized thermal increase (at idle, moderate load and full load) as well as less consistent voltage being supplied to the CPU. Be advised this setting (when set to extreme) will produce more heat and increase total system power consumption depending on which option is selected.
Intel Adaptive Thermal Monitor - The Adaptive Thermal Monitor feature is intended to help protect the processor in the event that an application exceeds the TDP recommendation for a sustained time period. As such during the course of overclocking this can affect the stability of the frequnecy defined. As such it is advised it be disabled when under overclocking and stress testing with high load and high power consumption sythetics or applications. Be advised this will not disable the CPUs internal TCC functionality.
Thermal Control Circuit: Thermal monitor uses the TCC to reduce the die temperature by using clock modulation and/or operating frequency and input voltage adjustment when the die temperature is very near its operating limits. When at a range of approx 87 to 91c this will kick in and generally shutdown the system to ensure CPU functionality/lifespan.
C States - These setting defined whether C States protocols are in effect more advanced sleep states allow for deeper levels of clock gating and especially help to improve power efficiency and minimize thermal load as the CPU frequency will vary depending on load. In internal testing we have found generally C States to not readily impacting CPU scaling up to and around 4.8GHz. Be aware though potential PSU initialization issues can occur at deeper C States than can affect cold posts and rebooting. This in addition to memory training at post can cause potentially instabilities. For maximum power efficiency and reduction of consistent thermal load (reduced temperatures C States are advised to be enabled. Once reaching 4.8GHz a tradeoff is generally something to consider and to ensure superior smoothness in cold post/rebooting of an overclocked system it is advised to disabled C3-C7.
Anti Surge Support - This setting is important to overclocking as the Super/O controller can tell the difference between high current draw/high power consumption relative to overclocking vs. a potential surge, spike in the power line. As such this setting can limit high frequency (and high CPU vid) scaling causing the system to cut off or produce a stop error. Once at a frequency level of approximately 4.7GHz or 1.45v is achieved it is advised to disable this option to ensure smooth scaling especially under high voltage and high frequency parameters.

Also the screenshots make it hard to follow....You should had made a table with 2,3 OC variations, would be easier for people to follow.
Please if this is just an agreement with the guys at ASUS to promote their products rename it to ASUS X79 Overclocking Guide, otherwise search and see what other settings the other mainboards in the market have so people can actually use them regardless of what model they have.
