Hi,
I would like to "disable" the Memory Clock increase of the GPU when the laptop is AC connected. I've replicated the same behaviour either on Windows and Linux, so this its not related to OS energy profile.The powersave energy profile on battery works flawless ( Windows/Linux ) almost all time silence laptop, but when AC adapter its connected, the GPU increase his "mclk" ( memory clock ) from 400Mhz to 933Mhz ( windows/Linux ) and the fan start to work every 5 or 10 minutes due this. Independent on the video usage. Who is changing this parameter ? Lenovo says they do not alter that option in the bios. I dont need more gpu power for my laptop.
Would appreciate your help.
Thank you in advance.
