P100 + Gemma not working properly?

Reply in thread

Nah, the PSU controls the voltages. All the motherboard does is turn on the PSU by shorting the green PS-ON wire in the mobo cable to ground. The thunderbolt card actually came with a switch to do that, normally I use a paperclip :D.

PS-ON is an active low signal that turns on all of the main power rails including 3.3V, 5V, -5V, 12V, and -12V power rails. When this signal is held high by the PC board or left open circuited, outputs of the power rails should not deliver current and should be held at a zero potential with respect to ground. Power should be delivered to the rails only if the PS-ON signal is held at ground potential. This signal should be held at +5VDC by a pull-up resistor internal to the power supply.

Here is an example of a switch: https://a.aliexpress.com/_msxxnjv Mine doesn't have the third wire, I think its just for powering the switch LED though.

Current suspicion is that because I'm both passing through and using thunderbolt, the GPU isnt getting properly reset at reboot, and is getting to a broken state.

I'm gonna try removing the VM portion of the chain when I get a spare PC. And maybe if that doesnt work I'll try drop the thunderbolt part as well, but that is a little harder to deal with.

Some GPU gore in the image:

"feminine"

Bed frames are feminine, put that mattress on the floor. While your at it, get rid of the sheets, bare mattress it up.

Lighting is too fancy, fancy is feminine. Plain flickering bulb is what you want for ambiance.
