Re: X1 Extreme throttling at really bizarre temperatures

Deactivating Virtualization doesn't solve it for me. Looking into Throttlestop I see CpuMaxTemp/PROCHOT is set to 85C. Ironically the fan isn't even running at this temp, creating a vicious cycle, worsening performance even more...

@Lenovo Please fix it.

Anyone tried intalling an older version of Intels / Lenovos Thermal solutions driver / software? Because, you know: in the beginning it worked just fine.

Re: X1 Extreme throttling at really bizarre temperatures

I have just noticed today that I am also getting some really bizzare behaviour with thermal throttling. Thermal Throttling, according to XTU, seems to be kicking in around 60c!! have Intelligent Cool set to off, Performance plan, and Windows battery set to "Best Performance". I don't use any virtualisaiton software. 

 

A couple of odd things that I have noticed recently are

 

1) With Windows Battery set to "Best Performance" and when in Lenovo Vantage, with Intelligent Cooling switted off, and selecting "Cool & Quite", a message box would pop informing I need to change the Windows battery setting to "Better Performance' before "Cool & Quite" could be activated. Now this message box doesn't appear, and I can select Cool & Quite with Windows battery set to "Best Performance". Strange? Seems something is broken. 

 

2) Windows Update. An update for "Lenovo - Input - USB Enhanced Performance Keyboard" started appearing and always failed. I don't have, and never had this keyboard. Looking online, a few people have come across this weirdness, and the answer seemed to be using a MS utility to hide / silence the update. I have done this, so I no longer see it. Still, it is a little strange.

Even if you don't use virtualization software, virtualization may still be ENABLED in your BIOS, which for me caused 80C throttling every time, consistently, without fail (BIOS 1.17).

I did turn it off in the BIOS.

I'm also hitting this.  I use VT + hyper-v.  It's incredibly frustrating.  Lenovo support has not been helpful at all.

I confirm that. When I build C++ projects, CPU throttles to.... 1GHz!!!

Virtualization is off (BIOS), Intelligent cooling is off (Vantage), same on Linux and Windows.

I don't know what to add.

A screenshot is attached.

Everything works normal again: Fan works again and CPU max temp is 97C. So CPU doesn't throttle as bad as before. But IMO the fan should run stronger towards such high temperatures.

It is intermittent. 

Overall, it looks like it hits close to 100'C for  second, then goes down to 60'C 10W 1GHz and stays there.

Attached: a Linux screenshot.

OK, it is even more interesting.
It may appear things are normal because this bizzare throttling is triggered by continuous load.

I reproduce it this way:
1. reboot
2. start Intel XTU
3. start the CPU stress test
4. things run OK, CPU is 95'C-100'C
5. after exactly 1 min 15 sec, CPU throttles to 1GHz 10W
6. it stays spooky till the next reboot, any significant load causes it to throttle immediately (1GHz, 10W, under 60'C)


This behavior is *very* specific.


I wonder if any Lenovo engineers ever read this forum.

 

P.S. The other run got throttled after 45sec, the next one 1m20sec (rebooted after each run).
