Sep 5, 2019 · Increasing the VRM Switching Frequency from 500 KHz to 800 KHz shows very minor improvements. How does motherboard load-line settings really work and how does the voltage output change with it? Check these oscilloscope pictures to find out.

I know what is load line calibration, but what are the options such as "CPU Power Phase Control", "CPU Current Capacity", "VRM Spread Spectrum" and "CPU Power Duty Control", and what do they do?

Aug 18, 2021 · AC & DC Load Line can adjust the amount of overshoot and undershoot that occurs after the load is released (or in other words when the CPU goes back to idle). It is best …

These high-current very low-voltage power supplies are often called Voltage Regulator Modules (VRMs) if they are prepackaged in module form, or a Voltage Regulator Down (VRD) solution if the design is made up of discrete components laid out directly on the mother board.

Higher load-line calibration settings result in reduced VDroop at the expense of voltage overshoot and will increase CPU temperatures due to higher voltage under load. Select from level 1 to 7 to adjust the load-line slope. Level 1 = greater VDroop, Level 7 = minimum VDroop.

Mar 11, 2024 · Loadline calibration, aka LLC, is a tool to compensate for voltage drop (Vdroop) under load. Basically the CPU drops its voltage under load to mitigate a transient spike when the heavy load ends. Measured in Ohms.

Sep 4, 2019 · An R7 1700 at the same clockspeed will draw around double the current, and would provide a much higher testing resolution to analyze. What the 2400G is good for, is SoC VRM testing. If you stress the iGPU you'll pull much higher current on the SoC VRM than a CPU without an iGPU.

The implementation of LL had its genesis in the Intel VRM applications. As processors change power states and vary clock speeds, implementing LL has numerous advantages.
