I have a Maximus Xiii Hero and want to undervolt for lower temps.
Is it possible?

Hey there,

Undervolting without underclocking will lead to instabilities.
You may be able to do it a little bit, it's generally recommended though to underclock too.

In general for overclocking/underclocking you have 3 options.

1. Manual Core Voltage + Sync All Cores

All cores will be synced to your preffered ratio (lower ratio for underclock).
All cores will run at your fixed/static core voltage. (lower voltage for undervolt)
Example: All-Core 42x @ 1.15v (static voltage)


2. Auto Core Voltage + Sync All Cores

All cores will be synced to your preffered ratio (lower ratio for underclock).
All cores will run on a automatically controlled voltage. (lower voltage for undervolt)
Example: All-Core 42x @ 0.60 - 1.15v (dynamic voltage)


3. Auto Core Voltage + By Core Usage

All cores will be synced to the ratio specified by the core-usage, chosen by you. (lower ratio for underclock).
That means that the ratios will change basen on how many core are used.
All cores will run on a automatically controlled voltage. (lower voltage for undervolt)
Example: 45x-45x-44x-44x-43x-43x-42x-42x @ 0.60 - 1.15v (dynamic voltage)

** (values and voltages are just an example, they are not valid) **

When Auto Core Voltage is chosen, you can also use the V/F Curve to further offset the automatic voltage using Point Offsets.
My exaplanation is not the best, you may want to check this amazing video below, and use it as a reference for underclocking / undervolting instead of overclocking.

the most direct way is to enter v/f point offset menu,
start with -0.05v for the high frequency points vfpt8/7/6/5
