Is there a "default" undervolt applied when you first install? #108

Closed spiff72 closed 4 years ago

spiff72 commented 4 years ago

I just installed Ubuntu 20.04 as a fresh install (after using 19.10 on my Thinkpad X1 Extreme Gen 2), and I have Throttlestop installed on the Windows side of my dual-boot.

I copied the throttlestop.ini file from my windows setup to a folder on my Ubuntu install, but it is buried in a folder and I did nothing but copy the file over.

After first installing undervolt with pip3, I ran sudo undervolt --read, and it gives me values that are very similar to those I use in Throttlestop. Is this just coincidence? Or does the setting from Throttlestop in windows somehow get carried over to the linux side of my dual boot?

I get these values when running the --read option: temperature target: -20 (80C) core: -125.0 mV gpu: -75.2 mV cache: -125.0 mV uncore: 0.0 mV analogio: 0.0 mV

Thanks!

Well this is really weird - I just ran the command again, and now it states: temperature target: -20 (80C) core: 0.0 mV gpu: 0.0 mV cache: 0.0 mV uncore: 0.0 mV analogio: 0.0 mV

I have no idea how the other values above were generated...

some users have reported their settings persist through reboots, so I think it is likely the first set of values you got persisted from throttlestop in windows
