Dell Precision M6800 Laptop Quadro M5000M GPU Power Limit throttling issue at 100W

Did you face throttling with m5000m in your dell or hp workstation?

    We tested Pascal earlier this year (GeForce 1070 in M6800 and Quadro P5000 in M6700) and the power limit was around 120W for both. For my M5000M in M6700 I am seeing the same behavior as you. For some applications it will run close to 1100 MHz but usually I am seeing it stop at 962 MHz. GPU-Z never reports power throttle.

    That's interesting with your M5000M in M6700. Usually these M5000M ship with 1050 Boost freq & 962 as Base freq. So if you say that even in FurMark it is not stepping below 962 then it is operating at >100W. If you can confirm then I will just buy the M6700 and shove this M5000M in there.

    No. I tried Furmark just now (this is not a tool I usually keep on hand). It bounces between around 735-750 Mhz and GPU-Z reports power throttling — very interesting, nothing else I have put this card through reports that.

    Furmark isn't representative of any sort of regular workload so it doesn't bother me if the GPU can't run it at 900+ MHz.

    Wow. Now we disovered that it does throttle on M6700 too. I do understand that it doesn't bother a lot of us. However, to the ones that would like to extract more juice out of the M5000M, the vBIOS mods to improve clock rates can be a mess because there is almost more than 15C headroom (thermal throttling at 87C). Potential is being wasted a bit.

    I was asking for FurMark because I have seen it in a few other applications like games and professional rendering workloads.

    Do you think there is something we can do to about this?

    I don't really know. I haven't spent any time trying to push the M5000M further. Back when I was on a K5000M I was able to overclock it pretty simply with a modded vBIOS and NVIDIA Inspector. I'm not sure if M5000M is as simple, it seems that it is hitting a legitimate power limit of some kind as opposed to the K5000M which was just clocked way too low for what the card is capable of. It is possible to undervolt? I seem to remember that being limited to Pascal and up.

    See if the power limit slider is unlocked with NVIDIA Inspector, MSI Afterburner or EVGA Precision X1. If it is, try maxing out the power limit slider and the voltage offsets sliders. It could be the driver is ignoring your modded vBIOS power limits based on the hardware ID. You can also try opening an admin command prompt and pasting this command. See what NVIDIA SMI reports as the maximum watts. Then try to set that value using the same command (instead of 2000).

    Code:
    C:\Progra~1\NVIDIA~1\NVSMI\nvidia-smi.exe --power-limit=2000

    furmark is a bad tool to test with, nvidia has implemented code especially for furmark, in that the gpu throttles once it detects that tool.

    Agree. That could also give a false read on the power performance cap. I prefer using EVGA OC Scanner Julia test.

    Clocking M5000M is just as simple as K5000M. Just have to adjust the right sliders. the attachment shows the undervolted m5000m running heaven load <100W. this is different with other applications as mentioned earlier.

    Thank you. I just confirmed that it is indeed capped at 100W. ref attachment. I followed the code C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe and it displays 100W as pwr limit.
    I couln't adjust beyond 100W as it says the value of power limit must be between 0-100W.
    The power limit and other sliders aren't unlocked in third party OC tools.
