Idle speed vs rated max speed, at isle desktop the speeds idle down to save power, under load it ramps up, Nvidia Pascal boost can and will increase speed past rated speeds on the GPU core depending on several factors, load and temperature, the cooler the card runs the higher it will clock
Idle speeds

Using GPU-Z click on the ? to run the render test and you can see the speeds increase

This happens in real-time during normal use, also memory speeds use a multiplier, similar to desktop memory, 2X, 4X, depending on what software you use for monitoring

Thanks Menthol. I did`nt realize that clock speeds ramp up and down. When i was opening Firestorm or Afterburner, this was at idle. So, those speeds I was seeing are the idle speeds. I thought my GPU was under clocked. I`ll check out that GPU-Z render test when I get home this evening.

When idling a GPU is underclocked for save energy reason. If you want to render the nominal speed of a GPU without stressing it and without trigger GPU boost, just open nVidia control panel -> manage 3D settings, then scroll down and check for the voice "power consumption management" and select "prefer maximum performance".

Reboot and you card should be clocked at nominal speed in idle.
