    If I undervolt my 7700HQ will I lose turbo boost/gaming performance on my laptop? I want to keep the 3.8Ghz turbo boost intact so I don't know if I should undervolt, and by how much. Thanks in advance.

    Keeping the 7700HQ at 3.8GHz is not possible. 3.4GHz is the max 4-core turbo

    Why? Intel's website says the max turbo boost is 3.8GHz. But even if 3.4GHz is the max, will undervolting about 100-120mv drop the max turbo boost? Because this amount is about what people can get without performance drop, but I don't know if they are referring about performance drop from stock or turbo boost frequency.

    Undervolting doesn't affect clockspeed or performance, it may affect stability. That's why people stop at about 100-120mV - because otherwise it becomes unstable and starts crashing. As for the Turbo numbers, Intel claims 3.8GHz on 1 core, but modern games almost always tax 4-8 cores meaning that 3.8GHz is pretty much impossible.
