Please don't use that kind of title for your future threads. You're trying to push things and get a BSOD just work the problem and there's a solution. Voltage is an issue in this case with how high you're pushing things.

RAM voltage seems high unless that's how you bought them. I'd recommend setting the CPU PLL to 1.7v and the VTTCPU seems to be fine. I know you don't want the VTT over 1.2 otherwise I don't know too much about it.

LLC enabled? If not then the voltage difference is the vdrop. The feature called load line calibration will increase the voltage input to balance the sudden need of more juice when running prime.

Sorry bud...but that's not how the Sandy Bridge E overclocks. Per the MSI X79 Platform Overclocking guide...

hey i set my cpu pll to 1.7v i had it at 1.9 was that to high? what does that do? also i left everything else the same i up more on the cpu voltage to 1.45v and set the cpu loadline calibration to high and now my vdroop is at 1.43v to 1.45v instead of 1.40v to 1.42v i ran prime for 30min and it ran fine with temperature of 48c at 4.8ghz @1.45v, i know 30 min is nothing on prime and does not mean is stable BUT before i was not able to run 2 min of prime, so everyone's advise have helped a lot so please keep it coming and thanks you all

now i have my bios setting at:

BCLK 100
CPU 1.45V
CPU VCCSA 1.15V
CPU PLL 1.7V
VTTCPU 1.15
2nd VTTCPU 1.05V
PCH 1.1V: 1.10V



In the DIGI + POWER CONTROL:
CPU LOADLINE CALIBRATION HIGH
CPU CURRENT CAPABILITY 180%

That's good. This stress test:
http://www.xtremesystems.org/forums/showthread.php?201670-LinX-A-simple-Linpack-interface

Set the memory to the quarter of the total amount you have and put like 200 passes to let it run for a good 1-2 hour. It finds faster than prime errors. Prime can run a good hour without finding anything while this stress test find something in <2mins (hapenned to me!)

Try to reduce the voltage gradually if you are planning on running @ 4.8 24/7
Good luck!
