Need help with GPU P-State bug

[FNSaver]

Hello guys,

 

I'd like to thank everyone beforehand for reading. I'm bolding some words to make it easier to skim through.

 

I have an ASUS G750JZ laptop with 4GB GTX 880M. Before this one I had never encountered any problems with the laptop or the GPU and it's quite weird and I am running out of patience. Basically, what happens is that whenever there is no monitoring software running which shows the clocks, the GPU runs at P-State P0, which means it's running at the max clocks. This happens even on idle. However, as soon as I run any monitoring software such as GPU-Z, HWInfo or Nvidia Inspector, the clocks go back to normal and the GPU idles normally. The P-State goes back to P8 - the state it should be when it's idle.

 

I have tracked GPU usage using Process Explorer and there is no difference in GPU usage with or without a monitoring software running. At idle, the only two processes which show GPU usage are csrss.exe and dwm.exe which are both Windows processes. I'm dying for a solution for this because I bought the machine while I was working in a different country where I made more money, and it's impossible for me to replace it or get something that's nearly as good with my current wages.

 

The troubleshooting processes I went through have been going through countless different driver versions using DDU and 2 clean Windows reinstalls.

 

I am using Windows 7 Ultimate 64-bit.

 

Has anyone encountered a problem like this before? I'm open to any and all suggestions. Thanks in advance.

Sorry how do you know the gpu state if you have no monitoring software open? sound? heat?

 

Is the process of launching a program causing the gpu to spike (or clock up) then return to idle?

Heat. Since it's a laptop, it's not hard to notice when I touch the right corner of the laptop where the GPU is. Program launches don't affect it - the only way it idles properly is if it is monitored. The other alternative solution is using Nvidia Inspector to lock it to P-State P8.

 

Thanks for your reply

Interesting.  This is a common problem with Nvidia Cards, I had similar issues on a 144Hz multi-monitor desktop set-up.  

 

Other that Nvidia Inspector not sure anyone has an easy solution, good luck.  Please post back if you find anything interesting.

Thank you. I'm on 60Hz but I appreciate the replies anyway. Hope we can find a solution. Cheers

Try NV control panel, maybe it's set to maximum performance. Set it to optimal power, Adaptive and close every background app to see if it drops. 

Disengage Shadowplay replay thingy and close any GPU accelerated gpu load. (Web Browser, video players, etc).

It's set to adaptive and I don't have Geforce Experience installed (don't like it). This was still a problem when the only thing installed on the computer was Windows and Nvidia drivers so I'm pretty certain it's not about hardware acceleration
