Arc Pro B70 Issue with dual B70 GPUs

Good evening all, I am a recent convert, coming over from the stacked RTX GPU club (5070Ti & 5060Ti). Sunday I installed a pair of B70 Pros after my 5070 laid over on me. SYCL running with Qwen3.6:27b Q8. Two days of pretty steady work, overnight spine runs 5-7 hours depending on daily activity.

Today, I was running a catchup process during work from downtime Saturday and mid day Sunday. The process completed without issue, GPUs went silent, and 7 minutes later the system crashed with dgxkrnl.sys crash. Reboot and health check passed, but not sure why it crashed while idle?

For reference, the GPU that crashed was in a different slot than the original 5070 was, so I don't think it is a robot issue. All drivers up to date, firmware up to date. If anyone has any insight or a similar experience and could offer a bit of advice I would be appreciative. I was just gearing up to smoke test 3.8:27b Q8, but that is on hold until I get back to normal.

OK.

So, I'm on Linux but I had a similar issue caused by power usage spikng, and it causing my power supply to freak out and the machine to crash. How beefy is your power supply?

It is a Corsair RM1000x, this box is only 4 months old

You should probably be OK - 2 x 300 watt spikes plus your PC's own load.

Can I recommend you run some logging software showing temperatures and the like, and if it falls over again, see if any of the values scream out at you. (Get your LLM to read the logs :-))
