Hello everyone!

Over the past year I purchased an Akitio thunder2 to run by GTX 780 with a bootcamp setup on my MBP early 2011. My PSU is a corsair 550w and the gtx is plugged directly in the thunder2 casing. (I modified the case to fit the big gpu.) 

My OS I use primarily with my egpu is windows 10 x64 home edition on a separate internal SSD. Thus far everything works very smoothly (plug in play). However, when I play planetside 2, over time I have run into a BSOD crash. The crash code is always nvlddmkm.sys. Even after running "whocrashed" that is always the error that shows up. I haven't figured out if it's a heat issue, a power issue (shouldn't be considering between the PSU that comes with the Akitio to power the pcie slot AND the 550w corsair PSU is all that's running power. Nothing else hooked up.) 

I haven't had this issue with any other game. The crash seems to be random and when it's under heavy consistent load. 

Anyone have any ideas as to what's taking place?

Also I'm running 16 gigs 660mhz ram. 

The windows install is through the uefi style (I believe that's correct as my native audio drivers will not work. Thankfully I have an external sound card - Presonus Firestudio mobile).

 

Thank you!

Consider trying these things to increase your eGPU reliability:

1.  downclock your video card's core as well as decrease the power target by 15% using MSI Afterburner. This will decrease both GPU and PSU load.

2. set your Windows power profile's CPU performance on AC to 99%. Doing so will disable turbo, dropping internal temps.

3. ensure your Thunderbolt cable is not coiled and is away from any major EMI noise sources. This keeps the Thunderbolt signalling robust.

Thus far I've had the GPU fan set to 100% and haven't had a crash yet. Will report back with an update. 

 

Thank you Nan!

This far running the GPU fan at 100% manually seems to have done the trick!

Hello, EOX. I have a similar setup as yours. But I think I'm missing something, because games are still using internal graphics and not my GTX 1050 TI. I'm doing that on external display, of course. Right now I can't do the trick to make it work with internal display.

I forgot to say that I'm having this issue on macOS Sierra. In Windows 10 it works flawlessly.
