Another follow to my previous comment. I’ve voluntarily triggered it again (not that hard, just some crazy camera movements)…I noticed this happening to my system.
Red marks where the crash happened. Mainly note the memory usage went max usage. The memory usage didnt drop until I clicked OK on the message (green).
This happened as I was testing an underclocked GPU in afterburner, as I see some comments above noting to do so. So it doesnt seem to matter if over or under.
