GTX 580 Overclocking Competion!

Hey all Alienware guys I am just telling you all that I have achieved the highest overclock on my unmodified GTX 580 on my Aurora, and here is my prof http://valid.canardpc.com/show_oc.php?id=1936048. By the way I am still experiencing problems from my CPU which keeps on showing the blue screen of death which says "A clock interrupt was not recieved on a secondary processor" although I have managed to move up base clock from last time stably I really want to hit at least 4.2ghz (I know guys from Alienware Aurora ALX overclocking problems it has moved up).
