Hello all,

I have a the Z170 Maximus VIII Hero board (0603) and 16GB DDR4 Corsair 2400 MHZ (XMP 14-16-16-31-2))

I have my overclock set to 4.6 ghz (turbo) and I notice the voltage is going past 1.35 to 1.4 (fluctuates) I set the voltage to 1.35v in the cpu voltage overide in the bios and cpu ratio is set to 46 and synch to all cores enabled.

Temps on idle 29c / 100% load is 58-61c using H100i GTX Corsair cooler. and no issues so far but what concerns me is that voltage it goes past 1.35v is this normal?

I believe

In the UEFI bios

The setting is this

CPU Core Ratio Per Core

1-4 Core Ratio Limit 46

CPU Core/Cache Voltage [1.376V] - Manuel
-CPU Core Voltage Overide - 1.350v
Dram Voltage - Auto
CPU VCCIO Voltage - Auto
CPU System Agent Voltage - Auto
PCH Core Voltage - Auto
CPU Standby Voltage - Auto

I have not changed anything in the AI Suite 3

Also another thing here is my Corsair Link screenshot

The CPU (H100iGTX) Cooler is blinking red but the fans are moving at slow speed but when hit load it goes up it is currently set in QFan (UEFI Bios) to DC should it be changed to PWM? I tested to see what PWM does and it removes the blinking red to showing actual fan speed rpm and it can be changed properly using AI Suite or corsair link. What is your opinion on this?

Btw if anyone wanted to know why I upgraded was this is new computer I got on the 2nd sept it came with 0403 but had to upgrade to 0603 because my K95 RGB and M65 mouse was having usb issues (starting up from coldboot) it has now resolved the issue.

I have a Maximus VII Gene and voltage is all over the place.

At 4.6GHz:

If I set to "Auto", it runs at around 1.35
If I set to Adaptive 1.4V, it runs around 1.32 and crashes
If I set Offset 0.005V, it tuns at around 1.44

If I want to target around 1.39V, i'm not sure if it's best to set Adaptive 1.39V and bump up the load line calibration until I get 1.39 or if it's best to set the adaptive target up around 1.46 to actually get 1.39V.

I'm really looking forward to a more mature BIOS version to say the least!

My voltage is at like 1.37 at default 4.2 in uefi bios at idle, all on auto, i was told not to worry as voltages change for all chips.

I use LLC5 this gives me 1.36V when set at 1.35V and at full load it can drop to 1.344V, I have only overclocked to 4560mhz (max I can get at that voltage any more overclock ant it wants 1.4v) at 1.35v temps are so low and I am running silent fans.
Now have a fast silent comp happy days.

Keep it S1mple Stupid

I use recommended by Asus adaptive voltage , for me works fine
im running stable 4.7 Ghz with settings
CPU Core/Cache Voltage (1,200v)- Adaptive
Additional CPU boost voltage -1.345v
CPU Core Voltage Overide +
Offset +0.004

In AI suite voltage go max 1,360 , so i guess BIOS always need add like 0,1 V - no idea why

currently im running 4,6 GHz with offset core/cache voltage +0,04V, everything else on default & auto, even llc and voltage in cpuz is around 1,39V in load and going down to something like 0,8V when idle
transoding h.264 -> h.265 in handbrake nearly all day and no problem 🙂

i just instaled new beta BIOS 902 , and i must say finaly shows properly voltage , same as CPU-Z or HWinfo , so far working well for me , i just had to set LLC 6 to get CPu stable

6700K Overclock? Set to 1.35 but it goes over slightly
