Mixed GPU Types with Thunderbolt 3 eGPU

Posted: Sun Apr 26, 2020 6:28 pm

I have 2 internal Nvidia RTX 2080 GPUS and an eGPU enclosure with an AMD Vega64. The AMD runs fine sometimes, then the eGPU disconnects, the fan on the GPU spikes to full blast, and I see this in the logs. This only happens when using the FAH Client. Is this the common issue I have read about where the client tries to assign an Nvidia WU to an AMD GPU? If so, is there a solution? Thank you.

Hard to say. This could be related, or it also looks a bit like the error messages we see in logs from persons with laptops that use both an iGPU and a separate higher power GPU active. If the WU starts, and the laptop is using the iGPU, then the folding core does not "see" the full power GPU and the WU errors out.

Any chance your eGPU is going offline in between working and not working?

Maybe you can run FahViewer on the AMD eGPU so it gets never idle between work units.

There are several reports of problems with certain driver versions for various Vega devices. This might be the same issue and you might fix it by installing an earlier driver version ... but you'll have to read the reports and the solutions and figure out if they apply to you.

@Joe_H - Its a desktop with the onboard graphics disabled, but I'll double-check all that again.
@foldy and @bruce - Thanks - I hope I don't have to track down an old driver.

The last change I made, and I am hoping to see if it continues to work like it has over the last 24 hours, is that I explicitly set the types of GPUs by setting the gpu-index on each slot, then based on the GPU, I set the cuda-index for the NVidias and the opencl-index for the AMD. If this was an issue of passing the -cuda-device flag to the AMD GPU, then it should be resolved. If not, I'll move to the next suggestion...thanks all!

Sometimes I see similar behavior on Nvidia GPUs that are plugged in pcie risers with another GPU sharing the sata power cable.
Sata power cables should carry 70W, and each pcie riser should feed the GPU with 35W, but when there are spikes a GPU gets kicked offline. I'd probably check the power cable to the riser, and see if the PSU isn't overloaded (or running close to its max wattage).
