Clevo N850hp6 GPU constantly power limit throttling

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.

 

have same thing on my clevo with gtx 1060. your best option is to oc or to flash modified vbios.

 

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.

 

How did you try flashing it? You need nvflash with disabled security check. You can check your full number with GPU-z tool. here's nvflash without security check http://forum.notebookreview.com/thr...6-owners-lounge.797128/page-747#post-10580891

 

Sorry what I meant is that I didn't attempt the vbios flash, as I have the same model card as you, for which no vbios seems available. I might try experiment with the overclocking.

 

So I've come across some threads where Clevo control Center seems to be causing very similar throttling behaviour to what I'm seeing. Is there a way to workaround this if so? I tried quitting control center and XTU service through Task manager, but this crashed my laptop. I have come across Obsidian PCs software, but I don't think the free version fully replaces control center?

 

won't help. I run my laptop without ccc, the problem is power limit throttle.

 

So did you have much success with overclocking the card?

 

You can undervolt the card to alleviate the power limit throttling. I've N870EP6 with gtx1060 and there is no easy way other than to flash another vbios which is not a risk i'm willing to take. The card is designed to throttle.

 

The card is designed to actively turbo as much as possible given the design spec is the other way of looking at it.

 

yes, that's the only way to gain boost other than flashing custom vbios. can run with +190 core clock, +700 memory clock stable.
undervolting won't do any difference because of the pascal architecture. the card will run at the undervolt and the core clock you set, but will get a lot lower performance out of it, because of a low power drainage. undervolt is only good to keep gpu running at low temps at not demanding games which don't use 100% of the gpu.

 

For whatever reason the clock speeds are way higher in Fortnite, with the card maintaining about 1750-1800Mhz consistently and much less power limit throttling. It is rather odd. Anyway thanks for all he responses, I think at the end of the day it's not a big issue though I may keep experimenting with overclocking.

 

The Witcher 3 is a much more intense application so will hit the system harder.

Boost is different as a result m, that's how it should be.

 

I see, well I've definitely learnt something by monitoring the hardware more closely.

 

Not a bad way to learn, it's how modern turbo works to get the most out of every load.
