ASUS ROG GTX 1070 clock speeds spiking and seem abnormal

Hey I am fairly new to PC gaming, just built a new pc and my gpu clock spikes every once in a while for seemingly no reason. Seems to correlate with the gpu voltage...

For example, the GPU voltage (in mV) sits at 625 idle, and GPU clock (in MHz) sits at 278 idle. But for almost no reason at all, suddenly the GPU voltage will go up to around 700 and the GPU clock will spike all the way up to around 1600.

I also decided to buy myself doom, and I'm running it on high settings at 1080p, 60Hz refresh rate, and almost the entire time my graphics card was maxing out on a clock speed of 2038 MHz, memory clock at 8014 MHz, but the GPU usage was only 51%...

Maybe I'm accidentally overclocking it? I just don't feel like these numbers should be the way they are..someone give me advice? I am up to date on drivers, so that's kind of out of the question.

1) Spiking is normal. Your CPU can do the same thing. It's meant to reduce POWER consumption when it's not needed...

No, that's how GPU boost work on Pascal cards :)
The GPU will work on max possible clock depending on temperature and power.
So basically you should be happy that your card reaches 2038 on its own. Mine was boosting to 1938 "only".
As a side note, start looking for a new monitor :) something like 3440x1440p@75-100MHz.

okay awesome, thanks! What do you think about the spiking though? it does it for simple things, like opening a new tab on a web browser. Voltage goes from 625 to 793, GPU clock goes from 278 to 1633, and Memory clock goes from 810 to 8014. Spikes for a second and then goes back down to normal...

1) Spiking is normal. Your CPU can do the same thing. It's meant to reduce POWER consumption when it's not needed.

2) FYI, your GPU usage can be capped if using VSYNC. If you have a 60Hz monitor, then enable VSYNC then the FPS output is capped at 60FPS. If you turned VSYNC OFF (which causes screen tear) you'd likely see your GPU usage go near 100% (depends on if a CPU bottleneck or not) and well above 100FPS since you mention 51% usage.

3) other:
There's a feature coming called "FAST SYNC" which may interest you. I tested it already. If you can output at least 2X the monitor refresh rate (i.e. over 120FPS for 60Hz monitor) it will still drive the monitor at 60FPS but it will feel less sluggish... less laggy.

Fast Sync simply has the GPU output a frame as fast as possible, then the GPU driver only sends the very latest complete frame to the monitor when it's time to draw a new frame. This means some frames are never shown, but when they are they tend to be newer than if locked to 60FPS output from GPU thus the game responds quicker (like turning your character).
