Why might a laptop GPU's core clock become stuck at a set value?
The core clock of the RTX 2070 GPU in my HP Omen laptop has become stuck quite frequently over the last few months. It can become stuck on boot up or after gaming for a short while.
When it becomes stuck, the core clock will usually not clock above either 300MHz or 1215MHz, and there never appears to be any clear reason why this happens.
I have taken all the steps I can think of to rectify it, but nothing works;
- The GPU drivers are the most up to date.
- I’m running the latest version of windows.
- I have the latest BIOS update for the laptop.
- I have ruled out any third party software as being the culprit through a process of disabling/uninstalling then testing.
- I am running monitoring software and CPU undervolting software to ensure the GPU isn’t throttling due to heat or power limit (and the issue occurs playing very light old titles as well as new, and the GPU never exceeds 60c).
- I have restored and recovered the system on more than one occasion.
- I have benchmarked the GPU (which confirms when it is working that it performs well).
The issue usually goes away on reboot, but sometimes it does not, and requires a full system recovery (starting a fresh) to be fixed. This usually gives me a month or so of gaming without any trouble before the issues returns.
I’m completely stumped, and so are HP support. Does anyone have any ideas?
