Hello, I bought a a Lenovo Y50 few days ago. It has GeForce GTX860M GPU.
When I run my program where I need the full load of my GPU everything is OK, but as soon as I close the lid the the GPU Core Clock goes from 1020 Mhz to 405 Mhz and GPU Memory clock from 2505 Mhz to 405 Mhz as well, causing my program goes from @13 FPS to incufficient of @6 FPS.
When I just turn off display it doesn't matter, only closing lid cause the problem. I use VNC from tablet so I don't need laptop's display running and need to have it in the backpack.
It's happening even when power cord is plugged or unplugged.
nVidia drivers up-to-date: 340.52
Things I tried:
Choose "When I close the lid: Do nothing" in power options.
Power options set to: High performance
In nVidia control panel I Power Mgmt mode to: Prefer Maximum Performance.
Looked in BIOS but the was nothing about Clock of my GPU
any ideas how to fix this? I really need this working and have no clue what could cause this auto-underclocking GPU on closing lid.
Thanks in advance.
