Test bench rig kept crashing, turns out it was the riser cable

I set up a test bench last Tuesday with a spare GPU and a cheap 16x riser from an old mining build. Every load test would hard freeze after about 10 minutes, even after swapping the PSU and RAM. Swapped in a direct mount and it ran fine for 2 hours. Anyone else had riser cables cause weird intermittent faults like this?

My buddy dealt with this exact thing last summer on his bench setup. Same deal, cheap riser from an old mining rig, and it would lock up maybe 15 minutes into any game test. He swore it was his CPU for a week until he finally tried the direct mount and everything was fine. Those cheap risers just can't handle the bandwidth once things warm up, the signal starts dropping and the card chokes.
