Hi everyone,
I am wondering if anyone else has had a problem with system instability using the ATI HD7970 cards.
I have a problem where, if I try to use my workstation for anything while processing a model with PhotoScan, my system will freeze (sometimes in minutes, sometimes hours) if I try to do anything else. I have this problem in 0.9.1 and the 1.0 (1736) beta. Haven't tried going back to 0.8.5. Didn't occur with my NVidia cards. I thought it might be a temp issue and was carefully monitoring temps on this run, and both cards were both pretty low (60s and 70s) when this happened.
I am starting to wonder if it's a defective card, but have no idea how to figure that out. Nothing in the event log. Symptoms are that for a few seconds before the freeze the system stutters (redraw, mouse, sound if playing), then it becomes unresponsive. Sometimes one monitor blanks, but not always the same one - which makes me think maybe not the card.
I have more than enough power for both cards - I was underpowered before and that just shut off my machine.
Any thoughts?
