    Hi everyone,

    I've recently noticed an issue on my laptop which I'm not sure was occurring before. Basically in Msi Afterburner, I can see that my GTX 1060 is constantly hitting the power limit while playing the Witcher 3 (see the image). I feel this could be reducing the graphics clock speed and performance, as the GPU seems to only be able to maintain around 1600Mhz, with brief spikes up to higher clock speeds. Temperatures certainly shouldn't be an issue, as they are hovering around 70 Celsius and peaks don't even reach 80 degrees. Updating the graphics driver has not helped the problem.

    I saw a previous post in the forum where someone updated the BIOS. Could that be the issue again here? Or is this sort of power limit throttling just to be expected? I got the laptop from Eluktronics and am also trying to get their thoughts on the problem.

    Thanks for any help

    Luke

    The modern Nvidia GPUs are designed to turbo up against a limit, be it power and a game like the witcher 3 is going to be quite stressful. You could check some benchmarks to make sure it's expected but if the clocks and FPS are pretty stable then it's likely doing what it's meant to.

    Or just leave it if the performance is what you are after ;)

    Thanks for the responses. I feel the clock speed is slightly lower than it should be when I compare to benchmark videos. I knew thermal throttling was something I'd expect to run in to, but didn't think I'd see constant power limit throttling like this. I know some people get high GPU temperatures in reviews of this laptop, but I'm getting no high temps or thermal throttling at all, almost as if the power limit is throttling before temperature can become an issue.

    I might look into the vbios as you mentioned acekard. Any way to ensure you're updating to the right version? Just wary of messing up my graphics card trying to fix something which might not be that bad to begin with.

    I myself am looking for gtx 1060 10DE 1C20 clevo OC vbios, which raises power limit to 88w tdp, found only for g-sync 10DE 1C60 and also on chinese forum vbios for my card, but the links seems to be down so a bit unlucky. if you got gtx 1060 10DE 1C60 you can flash this bios http://forum.notebookreview.com/threads/clevo-vbios-repository.812918/ to raise power limit from 75w to 88w.

    Thanks that's some useful info there. Do you or anyone else have any idea whether raising the power limit is likely to affect the lifespan of the card at all?

    doubt that raising by that small amount of power will affect anything but peformance/temperature of gpu.

    No luck for the vbios flash @acekard, looks like I have the exact same card as you do.
