F3-12800CL9T-6GBNQ CPU constantly crashes (BSOD)

[Anthraces]

I recently built a computer with the following components:

RAM: F3-12800CL9T-6GBNQ (12 GB)
CPU: i7-920 (not overclocked)
MoBo: ASUS P6X58D (12 GB of this RAM is listed as compatible with this board)
GPU: SAPPHIRE Vapor-X 100281VX-2SR Radeon HD 5870
HDs: Rapter x2 RAID 0
PSU: PC Power & Cooling 75W
Cooler: CORSAIR Cooling Hydro Series CWCH50 (CPU never gets above 40C)
OS: Windows 7 64

At first it seemed stable. Then it started crashing every couple of days. Now it crash daily sometimes before i can even log back into windows. It crashes in game, while on. the internet, while idle...doesnt seem to matter. All drivers are up to date. BIOS is up to date. Windows log shows Power.Kernal

When i installed the ram it did not recognise 1600, it defaulted to 1066. doesnt really matter either way it crashes. Have tried to tweak various voltages, though i am not really sure what they should be set at. setting it to X.M.P. doesnt seem to work either...still crashes.

I am new to the ASUS BIOS and am not an overclocker so i am not sure what things should be set at. Everything is set to Auto as well so i cant really tell what it is automatically setting things to. Here are my current settings:

AI Overclock Tuner: Auto (XMP didnt work when i tried it either)
CPU Ratio: Auto
Intel Speedstep: Enabled
Intel Turbotech: Enabled
Xtreme phase full power: Auto
DRAM Freq: 1600 (Manually set to this)
UCLK Freq: Auto
QPI Link Data Rate: Auto
DRAM Timing Controls: defaults to 9-9-9-24-5-88-12-8-24-0 when set to 1600MHz
CAS Latency: Auto
RAS to CAS Delay: Auto
RAS PRE Time: Auto
RAS ACT Time: Auto
RAS to RAS Delay: Auto
REF Cycle Time: Auto
Write Recovery Time: Auto
Read to PRE Time: Auto
FOUR ACT WIN Time: AUto
Back to Cack CAS Delay: Auto
2nd information: defaults to 2N-61-62-62
3rd Information: Defaults to 6-6-18-10-10-10-7-6-4-7-7-4

CPU Voltage Control: Manual
CPU Voltage: Auto
CPU PLL Voltage: Auto
QPI/DRAM Core: Auto (have set between 1.2 and 1.4 with no luck)
IOH Voltage: Auto
IOH PCIE Voltage: Auto
ICH Voltage: Auto
ICH PCIE Voltage: Auto
DRAM Bus Voltage: Auto (have set between 1.5 and 1.64 with no luck)
DRAM DATA REF and CTRL REF on CHA, CHB, CHC all set to Auto

Load Line Calibration: Auto
CPU Differential Amplitude: Auto
CPU Clock Skew: Auto
CPU spread Spectrum: Auto
IOH Clock Skew: Auto
PCIE Spread Spectrum: Auto

I am pretty new at building computers (this is my third and most complicated) so i really dont have a clue what some of these BIOS settings mean. many are for OC'ing and i am not an OC'er (at least not yet).

Is my RAM bad? Are my settings wrong? Please help...this computer is driving me nutz!!

sorry posted before i could finish....windows shows the following error
Event ID: 41
Source: Kernal-power
Task Category (63)
"System has rebooted without cleanly shutting down first. This error could be caused iff the system stopped responding, crashed, or lost power unexpectedly" (not that that explination helps any)

Looking in TurboV (Asus) my computer is defaulting to:
BLCK Freq: 134
CPU Volt: 1.225
DRAM: 1.64 (manually set..defaulted to 1.66 last time...above intel recomendations)
QPI/DRAM Core: 1.375
CPU PLL: 1.8
ICH PCIE: 1.5
IOH PCIE: 1.5
ICH: 1.1
IOH: 1.1

right now i can barely keep my computer running long enough to access the log or system settings...

Try testing each module individually to insure none are defective.

Then try increasing QPI/DRAM Voltage to 1.50V.

Keep us posted on the results.

Thank you
