Undervolting HP Omen 15T i9-9880H

[NaveedJ]

Hello there, I would like to know if I don't undervolt i9-9880H would it be an issue. My laptop specs are

 

5VY11AV-7    NEW    HP Omen 15T    Core i9-9880H    16GB    1TB+512GB SSD    NO ODD    15.6" 240Hz    WIN 10H    Webcam    FHD (1920x1080)/NVIDIA RTX 2080 8GB/ENG. KB

 

I play apex legends and do design work with development. No video rendering so far but have plans to learn it soon.

It just runs faster with undervolt, you dont have to do it.

Can you recommend settings for undervolting?

I'm new to this thing.

I've never seen units do more than -200mV, but really it could be anything between -200 and -50 because default voltage behavior differs between models, let alone the silicon lottery of the CPU.

I tried to install Intel XTU but it's not working. Just give an error "XTU signature validation failed". I don't know how to use ThrottleStop.

Can any guide me how to use it or can solve the error of Intel XTU.

 

Thanks in advance.

In the screen shown in the last screenshot, check "unlock adjustable voltage" and pull down "offset voltage". Do the same to CPU cache (same offset) as you do CPU core.

 

If you're feeling adventurous you can do system agent, iGPU stuff only when iGPU is enabled.

Okay, I have set both on -50.8.

If I don't do any other change it will be good?

 

How can I test run these settings?

 

Was trying to install Intel XTU but it's giving me error so I switched to this software.

Before doing above settings, I noticed that I left laptop for some period and came back and it's was turned off. I have set the power options to 'never' but don't know why it got off.

Click "ok" and it will run these settings, you can stress test with say Prime95 but it doesnt guarantee stability as CPU will not run full speed due to the power limit being hit. You need to use it for some time and adjust settings if it gets unstable

I undervolted CPU & CPU Cache both to -50.8 and run Apex Legends game. The game was getting stuck and I can't play it. Then I reset the under-volt and stopped it then tired the game again now it was working fine.

 

After running for 10-15 min the temps were as below.

At this time I was not using any cooling pad.

if the  undervolt doesnt work, dont use it

Yes, I have reset it's settings and not using it anymore. I guess with 2080 Max-Q Design the thermals are pretty good.

 

Intel XTU was not working too. It was giving something certificate error. Added it to Defender as well but same issue.
