Re: [X1C6/T480s] low cTDP and trip temperature in Linux

> Out of curiosity, do you mind sharing what settings you are using to undervolt in Throttled?

 

It might be best to start a new thread for that. For, as one person has said (recently) - and I concur - it is useful to reserve this thread for the throttling fiasco and more particularly for the awaiting of the happy and hopefully not mythical day when Lenovo fixes that particular problem.

@tokyovigilante You cannot use Secure Boot with throttled, because throttled requires being able to write to MSR and PCI BAR.

I'd be happy to, but throttled is a fix for the throttling fiasco and it seems reasonable to discuss it here. I understood the earlier comments are more directed at the "are we there yet" "no" back and forth that has been going on between Lenovo updates.

For reference, my /etc/throttled.conf is attached (in a zip because of the attachment rules). These settings are probably conservative, but I have not had a single failure or panic while running extended compiles.

That is why I don't use secure boot Smiley Happy. I'm also using wireguard so can't use it anyway.

Re: [X1C6/T480s] low cTDP and trip temperature in Linux

Guys please start a new topic for the workaround !

Keep this ticket only for the Lenovo firmware fix related issues.

Than you.

You could self-sign your wireguard modules, but there is no such workaround for writing to the msr. But this is not the point, this should not be my issue nor concern in the first place.

Sure, and throttled has pros and cons as you point out. However it is an issue, and throttled can help while people wait. Frankly, the firmware update for my X1Y4 hasn't offered me anything beyond what throttled was doing, but I guess it is an "official" fix. Anyway, use throttled or not if it's right for you or not, I'm just saying I've had good results with it.

I certainly don't think continued discussion of throttled is inappropriate for this thread, given the first 9 pages weren't about the Lenovo fix, nor is a Lenovo fix even released for the T480/X1C6 AFAIK.

Re: [X1C6/T480s] low cTDP and trip temperature in Linux

throttled is not quite a full fix. Those with dGPUs are still stuck with the low temperature limit. Once the GPU reaches the trip temperature, it throttles itself. So, I'm stuck using the iGPU ):
