Why is my vccio voltage so high on auto. Brand new to overclocking.

[Palmonte88]

My setup: -ASUS ROG Strix Z390-e
*-I7 8700k
*-32gb tridentZ RGB 3200mhz ram (8gb x4)
-Coolermaster ma620p dual tower dual fan air cooler (massive)
-850watt 80+gold Thermaltake PSU
-ASUS gtx 1060 6gb
*-phanteks Enthoo pro case
-2x 250gb Samsung 970 evo m.2 ssd in raid 0 for boot drive
-1x 500gb 850ev0 ssd
-1x 6tb toshiba hdd

*And what I did was
*-enable XMP_II
*-sync all cores
-And set the multiplier to 47
*Left all other settings on auto

**Why would my VCCIO be so high?
Is it because of the 4 sticks of ram?
And are any of my other voltages too high or unsafe?
*I don’t really know much about the technical settings and what each one actually does.
This is my first time overclocking and my first system build in 10 years.
I wanted a basic and safe overclock so I settled for 4.7ghz but left everything else alone.
*Any knowledge on what each voltage setting actually correlate to would Be greatly appreciated.
*And any advice on changes I should make Would be even more appreciated.*

If image doesn’t show my vccio voltage is 1.328 to 1.344*

Hi,
Sort of a strange quirk asus has gone to and maybe other board manufactures too I don't know

All I know is my x99 and 5930k was quite happy at 3200C14 4x8gb kit with vccio cpu 1.05v voltage at +- at that amount for years on 2101 bios

Any bios past 2101 for broadwell-e jolts vccio cpu 1.05 voltage to 1.25v darn near the core voltage for 4.3 takes 😄

Why, well it wouldn't be first time auto voltage didn't zap more than needed into the system if you had vccin/ input voltage you'd know what I mean lol on auto might produce 1.2v into a system and system agent as well just for the sake of brute force.

Lastly use hwinfo not hwmonitor.

Thanks for the reply. I do also have hwInfo but it has a ton of readings and I’m very new to this so i don’t know what they all mean. * Some of them like temp sensor 9 read like a million degrees. And others like temp sensor 3 show readings of like 3 degrees C. *Idk what they could possibly be reading but nothing in my system could be that cold (or in case Of sensor 9 reading temps in excess of 200C) that hot or something would just be on fire.
* In regards to my original reason for this post. I am in contact with ASUS engineering team who have been very helpful, and after several back and forth emails with them I am currently waiting for them to verify my findings regarding my memory modules voltage requirements being very high. As per the manufacturer website specifications for the exact model number of my modules “F4-3200C16D-16GTZR” (which is what ASUS engineering team requested me to provide) it is listed that the modules require 1.35 v or were tested at 1.35v. * And as far as me doing some tinkering and trying to lower the VCCIO, lowering it below 1.3v causes the system to be unable to boot or even get into the UEFI and change it back, I actually had to clear cmos (this was before I knew about holding the power button for 6 seconds) to be able to get back in.**However if I disable XMP the ram does not run at 3200mhz (I forget what it’s set to run at without XMP but it is much lower), *and the vccio also runs lower. But in order to run at the 3200mhz, which is what the manufacturer specification states they run at, I can not lower The VCCIO below 1.3v or as stated above I can’t even get into UEFI.
*If you have any tips on what I could do to lower VCCIO and still be able to run at 3200mhz please let me know. *Or if, as stated a few comments above yours, it is okay to run them like this then I will just leave the vccio set to 1.3 or change it back to auto if that is what ASUS engineering says to do.
* Thank you everyone for all of your help. It is very much appreciated as I am a first time overclocker learning as I go and also not looking to push anything too far or too hard. Just looking for a safe and stable 4.7 all core OC on my 8700k / Strix z390-e, and for my ram to safely run at 3200mhz.
* Thanks again everyone.

P.S. *No idea why when replying on my iPhone it places ( *’s) *in random areas that should just be spaces. *

Hi,
I have no idea what a safe voltage might be on your platform
Just shared something I noticed on new bios for my x99 board which doesn't need anywhere near what auto voltage produces 😄

x299 is pretty much the same on it's input voltage and system agent voltage over zapping
I haven't noticed it zapping vccio as high though seems docile compared to your platform and x99 for sure 🙂
