Help with overclocking

[bhackbob]

I recently purchased an i5 4670k and a msi z87-43 motherboard. I'm trying to overclock, nothing major i only want about 4ghz, but when I do this my computer will boot with the overclock just fine and work properly doing normal things like serfing the internet etc.. But when i go to play battlefield 3 (ultra settings) it will work just fine for about 20 minutes of playtime and then i get the dreaded blue screen. Also when i leave my computer and come back to it after it already goes into sleep mode it says that the overclock failed and that it is booting with default settings. Ive checked the temp and it stays at about 50-55. If anyone has experienced problems like this or knows how to fix it please help me out. Like I said i dont want anything major just 4ghz.

 

Thanks
