hi all ok my question is has any one ever over clocked to 4ghz stable?

i have msi 790fx-gd70 psu kingwin mach 1 1000w and the rest is with cpu-z.

i dont know how to add the actual picture here so below i have added the picture to my cpu z

what i have done so far was under clock the nb that way it wasn't high. under clocked my memory and tried 4ghz at 1.55v and 1.60v it would load desktop but when i try to run CPU z PC shows BSOD. so i tried to many settings i still don't get nothing so i am stable at the current setup. i disabled amd cool and quiet and still the same results.

i have read around people got it to 4.1 ghz stable and used prime95. so what am i doing wrong? its not a heating issue cause my home is at least 50 degrees and cpu is cool at 28-30c

What is your cooler ? if your cooler performace below noctua nhd-14 / H100 , you can't get it.
Also overclock fsb will safe use dual chanel ram and seem your ram not strong at 3:8 (1066) in high fsb, this need drop ratio at 800mhz and raise voltage ram at max 1.65v.
