So I just build a new machine:
- 6900K
- Asus Rampage 5 Extreme E10
- G.SKILL Trident Z 32GB DDR4 3200 Mhz 14-14-14-34-2N (F4-3200C14Q-32GTZSW)
- See signature for further details
Motherboard settings are default except that I enabled XMP for my memory. I ran HCI MemTest for 24h+ via a USB book stick and the RAM appears stable (http://i.imgur.com/mgc1Uzyh.jpg).
I use AIDA64 in Win 10 Pro to monitor my hardware.
Questions:
- In Windows I notice that my CPU clock will hit 4 GHz. Turbo for the 6900K is 3.7 GHz. How am I hitting 4 GHz - can the XMP profile be causing this?
- In Windows the CPU Core Voltage reports 1.250v. BIOS is set to auto. Even though I see the CPU clock down clocking when the PC is idle (drops to 2600 Mhz) I'm not seeing the CPU Core Voltage move down at all. On my R4E system, with a 3930K, AIDA64 will show the CPU Core Voltage going up and down depending on PC use, which is what I want.
Thanks.

I checked Windows Power Settings and even if I set the profile to balanced to the CPU voltage will not drop. I'll see the CPU clock drop, but never the voltage.

It is pretty easy to avoid XMP profiles doing this kind of thing....just set up RAM manually.....should be no problem to run that ram on 100 BCLK at rated timings. Just input these manually and set RAM speed manually as well a DRAM volatge.....

Oh yeah..should have seen that in screenies..
That's strange...like you have manual voltage set...is XMP setting manual voltage?

I think I figured it out.
With CPU Core Voltage = AUTO and Fully Manual Mode = Enabled, the CPU voltage is locked.
But with CPU Core Voltage = AUTO and Fully Manual Mode = Disabled, the CPU voltage is dynamic.
What I don't understand is if you can set the CPU Core Voltage = AUTO why does that NOT mean AUTO in all situations?
