GPU limited clock speed

[Seb_1]

Hi,

I have a Zbook 15 G3 with intel I7-6820HQ CPU and Quadro M2000m GPU on windows 10

For a while now i have seen random drops in performance from my PC. This slowdown can last many hours, regardless of if im using the PC or not and then everithing magically goes back to normal. Last time i noticed my PC slowing down, i ran the nvidia-smi -q command

What i noticed is that the GPU reports 100% usage and performance state P0 BUT it only runs at 284Mhz when the  maximum is 1137Mhz. This seems to be related to the flag Clocks Throttle Reasons -> HW Slowdown : Active

My understanding is that this flag is raised by the main board to limt heat or power usage.

I am using the original power supply for this PC (i tryed two different HP power supply 150W and 200W), i have a full battery and my GPU is at around 55 Celsius. I also updated my GPU driver and it made no differance.  What else can trigger this?

I am not sure but i think the issue might have started not long after i updated my bios to N81 V1.55 (before the update i was using a version from 2017, not sure the exact rev number). Is there an issue with this bios version?
