Custom eGPU: Dell DA-2 + GTX-1070: Blue Screen (Kernel-Power, ID 41) after ~4h GTA-V
Yesterday I received my final parts for my custom eGPU-build. It is my first GPU in general, so I'm not too experienced. But everything worked very plug&play and I'm really happy! My 14-inch i5-laptop now manages GTA-V on highest settings on a 3440x1440-screen!
However after some hours I got a blue-screen. The shown event is ID. 41 - Kernel-Power.
Now I suspect it could be caused by a power peak from the GPU and too small power supply? The DA-2 achieves 216W based on the Specs. Theoretically a GTX 1070 should have around 160W max power. But I've also seen tests where random peaks would go slightly above 200W.
Now my question: Could this even be a reason for a blue-screen (if eGPU has not enough power)? Or would the symptoms look different? If yes, are there nice ways to limit GPU-power to not reach these peaks? Would you know other reasons for this problem?
I'm asking this early because I soon would like to start building the enclosure for the eGPU. There I'd like to know first if I can use my PSU.
- Lenovo C940
- i5-1035G4 CPU
- 16GB Ram
- 2TB SSD (upgraded from original 512GP)
I would be very happy about every hint towards finding the root of this problem
Best wishes already for 2021!
EDIT: Just 2 minutes after sending this I had the next issue: The computer just froze. I couldn't do anything anymore. I never had this before (have the laptop already a few months). Only browser open, so no GPU load. First time after like maybe 10hours of running with eGPU.
EDIT2: This was again Kernel-power nr 41 in the windows-event-viewer. So really weird, this time without blue-screen and without any load. So yes, probably not the PSU....
EDIT3: Due to the new symptom (freeze) I could find more in the internet. I changed the Nvidia-GPU-settings to "maximum performance" as suggested by other threads. I'll see if this helps and if so update here.
Update for others experiencing the same:
As hinted by EDIT3, changing the Nvidia-settings solved the problems and I never experienced issues again in the last two weeks.
Open your NVIDIA control panel --> 3d-settings --> energy management mode --> Prefer maximum performance
(actual wording could be slightly different as I translated my settings from german)
