Well I have been playing games on the gfx clocks in my sig, such as COH, Supcom, Dirt and Oblivion. All fairly intensive games and have not had any graphical issues at all. However whenever I load either BF2142 or BF2 on the clocks below as soon as i click join game i get a string of artifact patterns evenly spaced across the screen, not speckling just a constant pattern and the video doesnt load but sound does...As soon as I drop down to stock clocks both games are fine. Now I know this isnt an issue with the overclocks and must be something to do with the engine but it baffles me as to why...(i know i shouldnt be since it is battlefield for gods sake lol). Can anyone shed any light on why this happens and if it has happened to them?
