true.The default profile has unnecessarily high voltages - may not bother some people but for those with OCD like myself I hate it
I tried the asrock pre set 4.6ghz overclock, when I put it under full load the vcore goes to 1.320v which is fine but when the cpu goes under a small load (18% cpu usage) the vcore goes to 1.380v~ which isn't good.
so I manually done it.
multiplier at 46
turbo power limits 200, 200
additional turbo voltage +0.031
CPU PLL Voltage 1.750v
vcore mode to auto
LLC level to 3.
under full load the vcore goes to 1.312v and when the cpu goes under a small load the vcore goes to 1.320v~, 0.960v idle
