Hi I'm using a Lenovo IdeaPad s340
I've had a bios update recently after that my GPU core speed kept dropping to 130
after like 5-10 mins of doing anything with it
and what is strange is changing the fan mode from performance to quiet and back to performance seems to fix it for another few mins and the same happens again
I thought it was a heat problem and I've undervolted using throttle stop which seems to help on the timing but not fix it
and with some testing, I found that if I disable turbo boost this issue go away but I can't do that cuz my processer is a low end
I don't play intensive games but the drop is so heavy that it affects any game
as an example, I usually play Minecraft with some lite shaders I get around 120-140 fps
but when the drop happens it goes down to 15-20

side note
after the same bios update
power limiting the turbo seems not to work as well
and the only way to do that is by using the power limit 4
might have a connection idk

i've tried to rollback on the bios update but i couldnt find it anywhere on the internet :facepalm:

Most likely the Bios update locked you out from undervolting.
Screenshots of Throttlestop will help to see any issue.
