Hello,

Using a Titan X (Pascal) for a deep learning application I notice in nvidia-smi the following:

```auto
Performance State : P2
    Clocks Throttle Reasons
        Idle : Not Active
        Applications Clocks Setting : Not Active
        SW Power Cap : Active
        HW Slowdown : Not Active
        Sync Boost : Not Active
        Unknown : Not Active

```

However the power utilised is way below the max:

```auto
Power Readings
        Power Management : Supported
        Power Draw : 81.54 W
        Power Limit : 299.00 W
        Default Power Limit : 250.00 W
        Enforced Power Limit : 299.00 W
        Min Power Limit : 125.00 W
        Max Power Limit : 300.00 W

```

Temperature is also low:

```auto
Temperature
        GPU Current Temp : 65 C

```

Could anybody explain why the clocks are throttled and the performance state is ‘only’ P2?

This is under Ubuntu 17.04 driver 375.66

Thank you!
