Need help with BSOD after OC

[Pitcher666]

Hi,

I hope that anyone can help me here.
Here is my pc specs :
i7 930
gigabyte x58a udr3
gtx 470
OCZ gold 3x2gb 1600mhz
H50 water cooling

I was under a stable 3.8ghz OC. I decided to try a 4.2 OC. After I tried some settings from a i7 920 user found on a website (200x21), it booted right, the temps were looking really good. Then I tried to run prime95 and the PC you restart itself after 1 second. I tried starting a game, it does the same thing. The BSOD is :
DRIVER_IRQL_LESS_OR_EQUAL
stop 0x000000D1 ( 0x094A, 0x0D, 0x08, 0x94A0

Here are my bios setting, note that it is a 930 with a x58a ud3r mobo :
200x21
turbo boost disable
cpu enhanced halt : disable
Hyperthread ON
C3/C6/C7 state support : disable
CPU thermal monitor : enable

Voltage

all other dram voltage to NORMAL(0.75)


Thanks for helping !

this QPI/VTT voltage : need increase voltage from default

generally Driver VGA / Sound can caused that !
- uninstall software OC GPU & installed the latest Nvidia driver,
