Greetings.

Laptop model: Lenovo Legion Y540-17IRH
GPU: Geforce GTX 1660 Ti

After few minutes of gaming the gpu voltage starts to regulary drop from 1 to 0.6 and it's causing huge fps drops. The GPU & CPU are not overheating, temperatures don't go over 55 and temp limit is set at 87.

Also, the CPU was randomly locking (again, with normal temp) hz to 0.79, but I fixed it with throttlestop by disabling BT Prochot. I have latest possible BIOS and drivers.

Please. help me with solving this problem.
