I have two 5700G CPUs serving my Gigahorse farmer each with a chia_recompute_server to access the OpenCL iGPU resources.
One of these machines also has an nVidia 1030 serving an official Chia client.

The 5700G with no nVidia GPU has a recompute server working fine.
The 5700G with the 1030 has a recompute server that runs for a few seconds and then crashes with an nVidia driver error.

I previously used CHIAPOS_VISIBLE_DEVICES=5 to force the recompute to ignore the CUDA card entirely, and have recently added the CHIAPOS_MAX_CUDA_DEVICES=0 but it still crashes on nVidia driver issues, despite telling it to only look at OpenCL.

The command line crash is below:

C:\Status>SET CHIAPOS_MAX_CUDA_DEVICES=0

C:\Status>SET CUDA_VISIBLE_DEVICES=5

Figured out my system drive was dying, so that file was actually corrupt. I've restored from backup and am running with no issues, so closing this.
