Load line calibration depends on what voltage you have set. And being Digi VRM or conventional VRM, every VRM monitors CPU activity and sets voltage accordingly. My motherboard does that too. I set 1.375 LLC on and C&Q off. It will be 1.368 idle and 1.4V extreme load and 1.380 moderate load(Songs, files, browser and all). So you see it is near the one I set in BIOS. But if you set 1.7V through the BIOS, even LLC will never allow 2.172V to be driven to the CPU. It is hardware limitation(VRM) and cannot be controlled by software(BIOS).
