Question XMP profile makes idle cpu voltage remain at 1.2v instead 0.800v

[amasoun]

CPU: i7 6700 non K
MOBO: ASUS Z270F
RAM: RIPJAW DDR4 3000MHZ
GFX: ZOTAC 3070 AMP HOLO
OS: WINDOWS 10 LATEST


I only wanted my RAM to run at 3000mhz, so I selected xmp profile and boom goes the voltage of cpu at idle.
I remains at 1.248v even when its idle in even in Power savings mode but cpu clock drops to 818 mhz.

And in Balanced mode, cpu runs at full clock speed all the time. So I have to keep my pc in Power savings mode.
Any help?
All I want is to run my RAM at 3000mhz and cpu to drop voltage at idle. And a little overclock without having high voltage at idle.

BIOS version for your motherboard?

When you enable XMP, it will put a low level OC onto the CPU as well. In your case, a bit higher vcore voltage for CPU.

And 3000 Mhz RAM is not "little OC". It is actually high-level OC since Skylake chips default RAM speed is 2133 Mhz. From there: 2400 Mhz, 2666 Mhz, 2800 Mhz and then 3000 Mhz.

E.g my Skylake chip (i5-6600K) also runs 3000 Mhz RAM but on CPU idle (300Mhz to 500Mhz), the vcore fluctuates around 0.776V to 0.836V. But different chip and completely different build, so, not comparable at all.

Oh, better to use HWinfo64 to monitor voltages/frequencies, if you're not already doing that.

All I want is to run my RAM at 3000mhz and cpu to drop voltage at idle. And a little overclock without having high voltage at idle.

Disable XMP, set RAM voltage to 1.35V, then set RAM clock manually to 3000 MHz and timings to 16-18-18-38.

The balanced mode issue has to do with the minimum utilisation setting in Control Panel Power Options. You need to set that to 0% and also C-States need to be enabled in your BIOS.
