  • AC_LL (AC Loadline)

    Controls the CPU load-line slope used by the processor's internal voltage regulator. Unlike LLC which affects the actual voltage delivered by the motherboard VRM, AC_LL affects how the CPU requests voltage from the VRM.

This setting works in conjunction with DC_LL and motherboard LLC to determine the final voltage behavior. AC_LL primarily affects transient voltage response during rapid load changes and can help stabilize all-core loads at high frequencies. Extreme overclockers often use low AC_LL values with high motherboard LLC levels for better thermal performance. Values are in milliohms (mOhm).

  • CPU Current Capability

    Sets the maximum current limit for the CPU power delivery system as a percentage above stock. This setting effectively increases the electrical current headroom available to the processor. While it doesn't directly increase the current, it removes limitations that would otherwise throttle the CPU when drawing high current during heavy loads. Higher values allow the VRM to deliver more current without triggering protection mechanisms, which is essential for high-end overclocking. This setting works in conjunction with Load-Line Calibration. Values of 140% or higher should only be used with adequate cooling for both the CPU and VRM components.

  • DC_LL (DC Loadline)

    Controls how the CPU reports its power and voltage telemetry back to the system. Unlike AC_LL which affects voltage requests, DC_LL affects power reporting and how the CPU measures its own voltage. Setting DC_LL too low can cause the CPU to report lower power draw than actual, potentially allowing it to exceed power limits. Setting it too high may cause unnecessary throttling. For the most accurate power reporting, DC_LL should match the actual impedance of the motherboard's VRM circuit. When manually overclocking, many users set DC_LL very low (0.01) to prevent power throttling, but this can be dangerous if power limits are also increased significantly. Values are in milliohms (mOhm).

  • Load-Line Sync with Cache

    Synchronizes the load-line calibration (LLC) settings between the CPU core and cache domains. When enabled, the cache voltage domain will use the same LLC level as the core domain, ensuring consistent voltage behavior under load transitions. This can improve stability during high-frequency cache overclocking, especially when the ring/cache ratio is pushed beyond 48x. In default mode (disabled), the cache typically uses a more aggressive LLC which can lead to voltage spikes during load transitions.

  • Memory Training Algorithms

    Controls which memory training algorithms are used during boot. Memory training is the process where the motherboard determines the optimal signal timing and voltage parameters for stable memory operation. Different algorithms focus on different aspects like command/address training, data eye training, write training, read training, etc. Disabling certain algorithms can speed up boot time but may reduce memory stability, especially at high frequencies. Advanced users may disable specific algorithms that are causing training failures when pushing memory beyond rated speeds. This setting is sometimes split into multiple sub-settings for each individual algorithm.
