Advanced Turbo 50 is some kind of Auto setting for 4.8GHz of somewhere around that clock speed. I don't remember exact frequency, but voltages were were quite high and I don't use that Auto mode.
CPU Load-Line Calibration fights against CPU v-drop under load. When level 1 is set, then CPU receives increased voltage in advance to compensate eventual voltage decrease. That rises CPU temperature, but helps to pass Prime95 or Linpack tests without errors. If you don't have errors in LinX or Prime95 in first place, use level 5 CPU LLC. That setting is a testimony for CPU power supply circuit quality. If it is good (typically ASRock one is often good), then you don't need level 1 LLC.
