GPU core jumping all over the place

in Hardware

I've never been one to run a bunch of monitors while gaming, so I've never noticed if this is normal or not.  But while playing ESO I'm noticing that my core clock on my GPU is jumping all over the place.  I know that during idle times core clocks will drop to idle speeds, but this looks a bit different.  It's going from 1329, 1228, 11xx something and all over the place between.  Is this just some type of dynamic controller only using what GPU power is needed?  Or is it a sign that there are other issues?

Sorry for the nublet question, but I've never been a huge one to watch HW monitors while gaming, so I don't know if this is normal or not?

Using a Evga GTX 980

    The 980, just like many other Nvidia GPUs since the (I believe) 600 series, have a base clock frequency and a nominal boost core frequency expressed as an average.

     

    The core frequency is the absolute minimum frequency it will run at but the boost clock is expressed as an average and it can be boosted at times higher than that and also lower.

     

    The algorithm used for this dynamic overclocking is complex and look at many factors including chip and memory temperature, power consumption, GPU load, memory load, etc.

     

    As long as you're not seeing any numbers that are lower than the base clock, you're seeing what you're supposed to be seeing.

    If you are going to watch numbers the one to look at is the Temp.

    If the gpu is performing well and you are not having any issues in game then dont worry about it. Maybe keep and eye on the temp while under load for a few hours. After that shut down the monitoring and just enjoy the game.

    With a GTX 980 dude you should be good to go.

    If it aint broke dont fix it.

    Yeah, the only reason i started looking at it, it started to chug a little bit in ESO around the doomcrag.  But temps across the board were fine, only 3 cores of 4 (8 virtual) were being used, memory was at like 20%, and gpu was barely being taxed.  Maybe its just bad portaling right at that particular part of the game.

    There's a dynamic controller that changes the GPU clock speeds based on what's needed. If the clock speed jumping around disturbs you, or you feel that's it's not working correctly, you can change the power management mode from

     Nvidia Control Panel -> Manage 3D Settings -> Power Management mode

    EDIT: You can also change the settings for just a single application (ESO). Just make sure the cooling is okay if you change it to work at max performance all the time /EDIT

    If you feel there's a problem with the card, it's also always best to make sure you've updated your graphic card drivers to latest version.

    There are parts of many MMOs that are CPU-bound not GPU... and then there is server lag, connection hopping that can hiccup on any node... MMOs are bad for assessing CPU or GPU performance or issues..
