Hi.
These are my settings for e8400. Orthos, Linpcak, OCCT, SuperPI, etc... all tests were OK, but when i start a 3d game (Burnout Pradise, Velvet Assasin, CoH:Tales of Valor) after a few minutes or seconds, freezes like hell.
First i thought it was win7, but it does the same thing under vista. VGA not OC-ed.
