I have a stability question,

With several loops on crysis using the ambush and GPU maps, maxing everything out I dont have any crashes / artifacts, same with the warhead benchmark and 3DM demo looped several times.

I do get a hardlock with Dragon Age 2, but im NOT sure if its caused by the GPU OC ( 1.088v , 900Mhz Core ) Dragon Age 2 stays at about 50-60% GPU usage.. The music in the background or sound continues but the system hard locks.. its NOT that often though and very very hard to reproduce!
