Log How do I undervolt my i9-9900K on my ASRock Phantom Gaming ITX

[MPKWGWBGATES1189888]

A Very Good Day to You All,

I hope everyone is doing Very Well,

I have a i9-9900K in my ASRock Phantom Gaming ITX Motherboard

Both are sitting in my DansCase V4.1

I also have a RTX2080Ti Graphics Card in this setup

So far Everything is running smoothly without any glitches

I noticed that the CPU Temps are a little high

I would like to do some undervolting to maintain a low CPU Temp

May I please kindly ask how do I undervolt my i9-9900K on my ASRock Phantom Gaming ITX

Please kindly see the 2 attached Pictures of my Bios Parameters

May I please kindly ask - What Settings should I set for each of the below Parameters

Hope to hear from you soon

Thank you and kind regards Sir

Good guide to read to get a general idea to undervolting your CPU.

Intel Extreme Tuning Utility (XTU) Undervolting Guide

News, Reviews and other Informations about Laptops

www.notebookcheck.net

The guide uses Intel's XTU software but you can use BIOS if you like.
You need to find the 'CPU core voltage offset' (or equivalent) in your BIOS.
From the 1st pic, click into 'CPU Core/Cache Voltage' and see if it is there.

Dear Sir,

Thank you for the quick reply

When I click on the "CPU Core/Cache" I get these options

Thank you Sir

The option you need to select from that menu is Offset mode.

CPUs adjust the voltage they use depending on the task they are performing. With the offset mode instead of setting a fixed voltage for the CPU to use at all times, you are setting the difference in voltage from the default.

To under volt you will set the offset to a negative value. You will need to test the setting for your particular CPU to make sure it is stable.

Start with a small reduction, then test using benchmarks such as CineBench and 3DMark. If the system is stable then reduce the voltage a bit more and test again.
