2700k overclocking issue

[gareth170]

hi

when I try 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 lite load (18% cpu usage) the vcore goes to 1.380v~ which isn't good.

so I tried manually setting the 4.6ghz, with:

multiplier at 46
turbo power limits 200, 200
additional turbo voltage auto
CPU PLL Voltage 1.750v
vcore mode to auto
LLC level to 3.

when I put it under full load the vcore goes to 1.304v which is fine but when the cpu goes under a lite load (18% cpu usage) the vcore goes to 1.260v~, but the clock speed goes to 4.6ghz still.

why when it's under full load the vcore goes to 1.304v or 1.320v but when it's under a lite load (18% cpu usage) the vcore goes to 1.260v or 1.380v?

I want the vcore to be at 1.304 or 1.320 under full load and lite load.

try changing the additional turbo voltage to its lowest value, or off if ur mobo lets you. its adding the extra voltage. u may need to up your vcore abit to counter act this.

is it safe to use is additional turbo voltage setting? and is this ok / safe settings?

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.

when I put it under full load the vcore goes to 1.312v and when the cpu goes under a lite load (18% cpu usage) the vcore goes to 1.320v~, 0.960v idle.

or is this better.

multiplier at 46
turbo power limits 200, 200
additional turbo voltage auto
CPU PLL Voltage 1.750v
vcore mode to +0.035
LLC level to 4.

when I put it under full load the vcore goes to 1.320v and when the cpu goes under a lite load (18% cpu usage) the vcore goes to 1.288v~, 1.00v idle.

I'd probably leave it on auto, my 2700k fetches 1.0107vcore on idle (1600Mhz) and around 1.35v~ when it's being hammered via prime95, and my multi is set to 46 with everything else in the bios overclock being left on default.
